Application of Optical Character Recognition with Tesseract in Logistics Management
by Sigurd Anders Berg, Soo-Yeon Seo, Richard Hau Yue So
Abstract: Warehouse and inventory management poses many challenges, for example in carton handling when upstream suppliers use labelling systems that are incompatible with a companys downstream system. In such cases, information is digitised using manual labour: this process can often become a bottleneck and, eventually, a source of handling errors. In this paper, the feasibility of applying Optical Character Recognition (OCR) technology in carton handling is assessed, and a prototype based on the open-source engine Tesseract is described in detail. Its performance on both printed and handwritten text is quantified, as well as the impact of turning the problem into a matching problem rather than a pure recognition problem.
Keywords: Optical character recognition; OCR; binarisation; Tesseract; logistics management; pattern recognition; image processing; warehouse material handling; business rule; data capturing; data integration.

Using Artificial Neural Networks to forecast producer price index for New Zealand
by Lin Lin Zhao, Bill Wang, Jasper Mbachu, Temitope Edbelakin
Abstract: Trend in the producer price is of much value to the central bank authorities in identifying the cost-push inflation that can improve their understanding of future directions of inflation in the aggregate economy and in formulating sound policies and macroeconomic plans. Forecasting of the producer price movement is complex; the popular use of conventional methods is fraught with inaccuracies which often produces misleading results and unreliable forward macroeconomic planning and control intent. This study explored the reliability and accuracy of the use of artificial neural networks (ANNs) for modelling and predicting producer price index (PPI) trend in New Zealand. Archival research method was used, which involved access and SPSS-based analysis of timeseries data maintained by the New Zealand Statistics and the Treasury over the period January 1990 March 2017. Input variables in the ANNs model comprised trade weighted index (TWI), interest rate/ official cash rate (OCR), and consumer price index (CPI). Lagged values of the PPI constituted the output variables. The study also compared ANNs results with those produced by the autoregressive integrated moving average (ARIMA) as an alternative. Results showed that the ANNs model outperformed the ARIMA model as a more reliable and accurate tool for timeseries data prediction. It was found that PPI timeseries data exhibited non-linear characteristics, making their prediction more suited to ANNs technique than the linear assumption, which underlie the conventional approach used in practice for such analysis. The results therefore revealed the key causes of inaccuracies and uncertainties surrounding existing timeseries model prediction efforts. The methodology developed could guide economists and macroeconomic policy makers in making more accurate forecasts and in formulating more workable policies and action plans targeted at cost-push inflation control. A strawman model of the potential causal relationships between producer price trend as exogenous variable, and the productivity and operating financial performance of manufacturing firms was proposed for further investigations. The proposed model recognises the uptake of industrial internet technologies as the mediating variable in the envisaged relationships in a multivariate setting.
Keywords: Artificial neutral networks; autoregressive integrated moving average (ARIMA); consumer price index; producer price index; trade weighted index.
Selection of Resource Service Chain with Conflict-Free Dependencies in Cloud Manufacturing Systems
by Haibo Li, Juncheng Tong
Abstract: In cloud manufacturing (CMfg), to improve the efficiency of a whole business process, all distributed manufacturing resources services should be selected as service flows, called Resource-Service Chain (RSC). However, selecting an RSC with conflict-free dependency is more difficult in collaborative manufacturing than in a centralized one, as resource services are usually selected independently by different organizations. To overcome this shortcoming, an algorithm based evolutionary algorithm is proposed. First, five common types of dependencies are defined after analyzing the relationship among manufacturing resources. Then, genetic algorithm (GA) is applied to find the optimal set of RSCs, in which the dependencies among resource services are considered as constraint rules. Finally, a collaborative business process is taken as an instance to verify the selection of RSCs with conflict-free dependency. The results show that it can improve the efficiency of resource service selection.

by Zhiming Zeng
Abstract: Manufacturing industry plays an important role in the national economy. However, it is worth noting that scientific and technological innovation in manufacturing industry is accompanied by risks. One of the important ways to solve technological risks is science and technology insurance. In this paper, we first analyze the development status of science and technology insurance in China, and then establish an index evaluation system by using the analytic hierarchy process (AHP) and the fuzzy comprehensive evaluation method. The index evaluation system includes three layers and selects 24 indicators, which can help the insurance companies to scientifically and quantitatively evaluate high-tech manufacturing companies. It also can avoid subjective and difficult-to-quantify problems in the past evaluation process. Finally, an empirical study is showed to explain how to quantify these indicators and how to calculate the weight coefficient values for each indicator. Our findings can provide relevant countermeasures and suggestions for insurance companies, high-tech manufacturing companies, and governments.

SOA-based distributed fault prognostic and diagnosis framework: An application for preheater cement cyclones
by Chouhal Ouahiba
Abstract: Complex engineering manufacturing systems require efficient on-line fault diagnosis methodologies to improve safety and reduce maintenance costs. Traditionally, diagnosis and prognosis approaches are centralized, but these solutions are difficult to implement on increasingly prevalent distributed, networked embedded systems; whereas a distributed approach of multiple diagnosis and prognosis agents can offer a solution. Also, having the capability to control and observe process plant of a manufacturing system from a remote location has several benefits including the ability to track and to assist in solving a problem that might arise. This paper presents a distributed and over prognosis and diagnosis approach for physical systems basing on multi agent system and Service-Oriented Architecture. Specifics prognostic and diagnostic procedures and key modules of the architecture for Web Service-based Distributed Fault Prognostic and Diagnosis framework are detailed and developed for the preheater cement cyclones in the workshop of SCIMAT clinker. The experimental case study, reported in the present paper, shows encouraging results and fosters industrial technology transfer.

by Hongguo Zhang, Chao Ma, Shuli Zhang, Shenghui Liu
Abstract: In the cloud manufacturing environment, the flexible job shop scheduling needs to handle the online task and offline tasks simultaneously, which make the processing time of equipment become from continuous to discrete. For solving this issue, a mathematical model considering discrete equipment capability was proposed. In this model, the additional profits constraint and the equipment capability conflict constraint are introduced. The former was used to promise the optimal solution is profitable for the manufacturing enterprise; the latter was used to promise the online task coming from the other manufacturing enterprises can be processed. Then an improved ant colony algorithm is adopted to solve this problem. Finally, the experimental results show that the flexible job shop scheduling problem with discrete equipment capability in cloud manufacturing environment could be solved effectively.

Wolf pack algorithm for optimisation of cutting parameters in WEDM using Taguchi method
by Yanqiu Xiao, Wuyi Ming, Dili Shen, Wenbin He, Jun Ma, Jianqiang Jiao
Abstract: The optimisation of cutting parameters for wire electrical discharge machining (WEDM) is one the most difficult combinatorial optimisation problems, due to their complicated, coupled and nonlinear nature of the input-output variables of them. An exact solution for a WEDM optimisation problem cannot be easily obtained within a reasonable amount of time. Therefore, a meta heuristic algorithm is required [e.g., genetic algorithm (GA), particle swarm optimisation (PSO), wolf pack algorithm (WPA), etc.)]. The objective of this paper is to develop a robust approach using WPA to obtain the optimised combination of cutting parameters for the process of WEDM. Hence, a Taguchi orthogonal array is proposed instead of a full factorial experimental design for determining the parameters of the WPA. The effects of the WPA parameters on optimising the cutting parameters are disclosed and an analysis of variance is performed to investigate significance factors on the results. By experiments of WEDM, an application was presented to illustrate the effectiveness of the proposed approach. Compared with the S/N ratio statistical method of reported previously, the performance of Ra and material removal rate (MRR) were improved by 12% and 3.99%, respectively.
Keywords: combinatorial optimisation; wolf pack algorithm; WPA; Taguchi orthogonal method; wire electrical discharge machining; WEDM.

by Meng Xiao, Qinhai Ma, Man Li
Abstract: With the transformation of social development and customer needs, the traditional model of value creation has been unable to adapt to market environment evolving. In order to enhance the core competitiveness of the firms, and meet the customers' needs, the value co-creation model was proposed and has achieved some good results. In the value co-creation model, customers and firms are brought into the process of production and consumption, and drawing support from the value proposition offered by firms. The business value and customer value are created together. Based theory of planned behaviour (TPB), the behaviour mechanism of value co-creation activities in the service industry between the customers and the firms are analysed in detail. Through the literature review, the theoretical model reflecting the relations among the concepts is established. In this study, the data were collected by the survey method. The structural equation model was used in the data analysis. The results showed that value co-creation attitude, subjective norm, and perceived behavioural control could truly affect the customers' co-creation behaviour. Finally, some suggestions and countermeasures that could effectively manage and motivate the value co-creation behaviour of the customers in the service industry were put forward.

Towards Business Process Recommendation based Collaborative Filtering
by Wei Luo, Zhihao Peng, Ansheng Deng, Xiaoming Bi
Abstract: Existing process recommendation methods cannot meet the various needs of personalized users. To address this problem, this paper proposed a personalized process recommendation method that is based on user behavior preference. This method combines traditional process recommendation with user behavior similarity and mines user behavior preference according to the historical tracks of processes that were performed by users. In the execution of a process, the execution trace of a behavior-similar user and executable candidate activities to be recommended that are provided by conventional process recommendation are analyzed. Then, activities or recommended activities for the current user are selected to realize the automatic construction of the entire process to meet the personalized needs of users. The experimental results show that the proposed method outperforms other methods in terms of accuracy and efficiency.

A Classification Algorithm Based on Weighted ML-kNN for Multi-label Data
by Ming Jiang, Lian Du, Jianping Wu, Min Zhang, Zexin Gong
Abstract: The ML-kNN algorithm uses naive Bayesian classification to modify the traditional kNN algorithm to solve multi-label classification problems. However, the ML-kNN algorithm is prone to misjudgment or incomplete judgment of the unseen instance's label set in two special cases: when the number of labels in the training set is not balanced and when the training instances are unevenly distributed in space. Therefore, a weighted ML-kNN algorithm (i.e., wML-kNN) is proposed in this paper. The main idea is to assign different weights to each label according to the proportion of labels and the mutual information of the spatial distribution of unseen instances to training instances. This method can reduce the probability of misjudgment of the unseen instance's label set. A comparative study was conducted on four multi-label datasets that included review classification and three other published benchmark multi-label datasets: yeast gene function analysis, natural scene classification, and musical sentiment classification. The results show that the performance of the wML-kNN algorithm is better than the other four multi-label learning algorithms, including ML-kNN.

by Y.P. Tsang, K.L. Choy, C.H. Wu, H.Y. Lam, G.T.S. Ho, P.S. Koo
Abstract: In cold chains, the essentials of cold storage are the chilling and freezing storage sections. Due to occupational safety concerns for the warehouse workers in such a cold environment, this paper describes a Bluetooth-based Access Management and Positioning System (BAMPS) to monitor worker location and movement in chillers and freezers, inspired by the growth of Internet of Things. In complying with the ISO11079, their occupational safety in term of exposure duration and recovery time in cold environments can be controlled. The Bluetooth Low Energy module is used for the transmitting and receiving sensing data in the cold storage environment. The positioning module is designed using Kalman filtering to eliminate signal variations instead of pre-requested calibration. Hence, the workplace ergonomics and monitoring in cold storage environment are enhanced. The significance of BAMPS is in exploring occupational safety management and real-time positioning in cold storage facilities.

Business Intelligence for Service Parts Logistics Management
by Nicole K. Y. Chan
Abstract: Many leading companies now offer global customers better spare parts services for system maintenance through a complex service logistics network, which extends traditional on-site stocking management to boost profit margins. The major challenge that spare parts service providers face is how to achieve desired service levels at a low cost and minimise excess inventory in the global spare parts supply chain. To address this issue, we demonstrate an inventory redeployment strategy that transforms a conventional spare parts supply chain into a closed-loop, multi-echelon service network capable of redeploying inventory from overstocked to understocked facilities, and thus reducing purchases of high-value spare parts. To assess the quality of our novel approach, we used a network flow optimisation model to analyse the proposed excess inventory redeployment strategy based on an international companys service parts operations. Significant inventory cost savings were identified.

Simulation Analysis of a Manufacturing Company
by Tommy Cheung
Abstract: Traditionally, many manufacturing companies focused more on the higher level of operation management, like assigning tasks to workers, and work scheduling. They often ignored low level operations and their timing optimization. As a result, a lot of these manufacturers suffer from inefficient and uncoordinated operations. Bottleneck would inevitably occur at some stages of the production, which caused the work-in-process goods to build up everywhere in the production plant. This paper used a simulation approach to analyse the low level manufacturing operations in details with the objective to identify the bottleneck and resolve the work-in-process inventory problem, without production out degradation.

by Jiuyun Xu, Xiaoting Sun, Ruru Zhang, Hongliang Liang, Qiang Duan
Abstract: The emerging IoT introduces many new challenges that cannot be adequately addressed by the current "cloud-only" architectures. The cooperation of the fog and cloud is considered to be a promising architecture, which efficiently handles IoTs data processing and communications requirements. However, how to schedule tasks to better adapt to IoT real-time needs and reduce the energy in the fog-cloud system is not well addressed. In this paper, we first model the energy consumption of the fog and cloud, respectively, and formulate a task scheduling problem into a constrained optimization problem in Fog-Cloud Computing System. Then, an efficient deadline-energy scheduling algorithm based on ant colony optimization(DEACO) is put forward to tackle this problem,which achieves to reduce energy consumption on the condition of satisfying the task deadline. Finally, algorithms have been simulated on the extended Cloudsim simulator. The experimental results have shown that our scheduling approach reduces energy more effective.

An Approach to Discovering Event Correlations among Edge Sensor Services
by Chen Liu, Yunmeng Cao, Yanbo Han
Abstract: In an IoT environment, a surge in sensor data volume has exposed the shortcomings of cloud computing, particularly the limitation of network transmission capability and centralized computing resources. To handle these issues, this paper proposes a service-oriented framework, called as INFOG, to support the dynamic cooperation among sensors with the fog computing paradigm. Proactive data services and service hyperlinks, which are our previous work, are two key abstractions for the INFOG framework. The services are software-defined abstraction of physical sensors. They are deployed in edge nodes in INFOG. And service hyperlinks, encapsulation of service correlations, enable the cooperation of sensors at the software layer. We also propose a frequent sequential pattern based approach to effectively discover service hyperlinks. Based on the dataset from a real power plant as well as several synthetic datasets, we do lots of experiments to verify the effectiveness and efficiency of our algorithm.

A CNN-based Temperature Prediction Approach for Grain Storage
by Liang Ge, Caiyuan Chen, Yiyu Li, Tong Mo
Abstract: Temperature prediction has a pivotal role in the grain storage phase. Accurate prediction results can optimize the effect of ventilation decisions and reduce the losses of stored grain. Most existing studies have only focused on layer temperature predictions whose predict particle size is very large. In contrast, this paper attempts to use Convolutional Neural Network (CNN) to predict the point temperature of grain piles. The CNN-based approach uses multiple convolution kernels that share weights to capture the characteristics of grain temperature at different locations, which make full use of the temperature information around the target point. Experiments on real business data show that compared to other conventional algorithms, CNN has the best prediction effect on point temperature prediction problems.

Design of candidate schedules for applying iterative ordinal optimization for scheduling technique on cloud computing platform
by Monika Yadav, Atul Mishra, BALAMURUGAN BALUSAMY
Abstract: In cloud computing, distributed resources are used on demand basis without having the physical infrastructure at the client end. Cloud has a large number of users and to deal with large number of task, so scheduling in cloud plays a vital role for task execution. Scheduling of various multitask jobs on clouds is considered as an NP-hard problem . In order to reduce the large scheduling search space, an iterative ordinal optimization (IOO) method has already proposed. In this paper, a set of 30 candidate schedules denoted by set U are created. The set U is used in the exhaustive search of the best schedule. After analyzing the set U, an ordered schedule vs. makespan graph is plotted. So in this work, set U is defined and created a base for applying IOO method to get optimal schedules. In this work, CloudSim version 3.0 has been used to test and analyze policies.

Mobile Self-organizing Network Positioning Algorithm Based on Node Clustering
by Jian Feng Cui
Abstract: It is not possible to correct the position of the node's space for traditional mobile self-organizing network positioning algorithms, which lead to low positioning accuracy. Based on the DV-hop algorithm, node clustering is used to optimize the DV-hop algorithm, and it is applied to node location of mobile self-organizing network. The narrative principle of mobile self-organizing network based on node clustering is completed by building RSSI ranging model. Combined RSSI technology to build a three-dimensional mobile self-organizing network model, we can obtain the strength of the mobile self-organizing network transmission signal and calculate the propagation loss of the mobile self-organizing network signal. Then, the transmission loss is converted into the node propagation distance, and the node position of the mobile self-organizing network is calculated. The DV-hop algorithm is used for positioning by the distance between nodes and the position of the anchor point. Node clustering is used to correct the spatial position of the node. Without increasing the hardware overhead of the mobile ad hoc network space node, the positioning accuracy is improved and the positioning range is expanded. The simulation experiment results show that node coverage of DV-hop positioning algorithm is higher than traditional algorithm. Besides, the spatial localization of mobile self-organizing network nodes is conducive to expanding the network space node coverage rate, thereby improving the positioning accuracy.

by Ming-cheng Peng
Abstract: During the process of self-organizing scheduling and control of vehicles, uncertainties often affect the operation of emergency vehicle road traffic. The traditional system cannot determine the road network connectivity, resulting in mismatch of transport routes and transportation vehicles, resulting in traffic congestion. To solve this problem, this paper proposes a wireless sensor-based information security scheduling method for vehicle self-organizing systems. Firstly, overall system is designed. Meanwhile, system hierarchy diagram and various modules of vehicle self-organizing system are introduced; Then, vehicle self-organizing scheduling model is established and design process of source code is provided. Finally, compared with differences of dispatch route length and management time of traffic dispatch for traditional neural network system and our proposed system security scheduling method, the superiority of our proposed method is reflected. Experimental results show that schedule length obtained by our proposed method is at least 200m shorter than those results obtained by the traditional method in the comparison of evacuation dispatch route length of traffic jam. At the same time, time consuming is at least shorter than those results obtained by the traditional method in the comparison of evacuation dispatch management time for traffic jams. Therefore, our proposed method is more efficient in slowing the congestion of vehicle self-organizing system networks.

Research on Algorithm of Information Transmission Path Planning in Big Data Environment
by Yun Fan Lu, Zhenjia Zhu, Xu Tan
Abstract: The information transmission path planning is conducive to the improvement of efficiency of information transmission, which matches requests of development of era. However, most of the information transmission path plans select transmission paths based on ID format. Although this algorithm can make nodes in big data environment reach the optimal path of sink node, it has high computational complexity. Therefore, an information transmission path planning algorithm based on an ingress-priority under big data environment is proposed. Based on this algorithm, a method for evaluating the information transmission path planning is obtained. Then analysis model of the information transmission path planning is constructed. Based on these, dynamic information transmission path planning is implemented by utilizing priority multi-actuators. Experiments show that our proposed method can effectively improve the efficiency of information transmission path planning, ensure the accuracy of information after transmission and improve the quality of information transmission.

Research on Virus Diffusion Prevention Method for Computer Singularity in Complex Sensor Networks
by Lei Ma
Abstract: In the current virus propagation defense methods, the case of immunization failure of singularity virus and the influ-ence of the combination of infectious vector and propagation delay in the process of propagation are not considered. It is hard to control the propagation of computer singularity virus with the current methods and the ability of defense is poor. For the case of infectious vector and propagation delay, a new SIS propagation model is proposed based on mean field theory. The influence of computer virus infectious vector and propagation delay in complex sensor net-works on the propagation property is analyzed. A new cellular automata model is built to simulate the whole process of computer virus propagation. By the information of abstraction layer from computer singularity virus detection model based on immunization principle, a fusion method for the singularity virus detection is proposed. Through the fusion of detection results of different antigen presentation gene library, the ability of defense of computer singularity virus propagation is improved. Experimental results show that target immune network connectivity factor ratio of our method is only 0.18, lower than 0.37 multiples of nearest neighbor immunity. Which indicates that viral immune infection density of our method is low. Therefore, our method can effectively inhibit the spread of the virus.

Outlier data mining of multivariate time series based on association rule mapping
by Yong-jun QIN, Arun Kumar Sangaiah
Abstract: In the outlier data mining with traditional methods, as the data is complex, the outlier
data is not effectively classified, which increase the complexity of data classification and reduce the precision of data mining. In this paper, an outlier data mining method of time series based on association mapping is proposed. By using association rule mapping between data sets, the association rule of data sets is determined. The mining factor and relative error are introduced to improve the precision of data mining. The shuffled frog leaping clustering algorithm is applied to cluster the mining factor. The cluster-based multivariate time series classification is used for classification of clusters based on training set category of time series combined with modified K-nearest neighbor
algorithm to achieve classification of time series data and outlier data mining. Experimental results show that running time is only 12.9s when the number of data sets is 200. Compared with traditional methods, our proposed method can effectively improve the precision of data mining.

RELIABILITY IN IoUT ENABLED UNDERWATER SENSOR NETWORKS USING DYNAMIC ADAPTIVE ROUTING PROTOCOL
by Jasem M. Alostad
Abstract: In recent years, the applications of the Internet of Underwater Things (IoUT) have meant under water wireless sensor networks (UWSN) are suffering mainly from a reduced network lifetime. Other challenges in the underwater sensor network include: limited bandwidth, high attenuation, high path loss, limited battery life and so on. The main focus of this paper is to consider a trade-off between the energy consumption and network lifetime. This paper proposes an optimal routing protocol called the Energy Dynamic Adaptive Routing (DAR) protocol. The DAR protocol maintains a trade-off between the reliability or packet delivery ratio (PDR) of sensor nodes and bit error ratio (BER) using an optimal dynamic adaptive routing approach. The proposed approach operates on three different phases, namely: initialization, dynamic routing and transmission. During the initial phase, all the nodes in the UWSN share location and residual energy information among all the nodes in the network. During the dynamic routing phase, an optimal directed acyclic graph (DAG) based route selection is exploited to select the neighbour and successor nodes. This facilitates the successive routing to transmit the packets from one node to another. Here, the cost function with a directed acyclic graph is utilized for better transmission of packets. The experimental results with BEAR show that the proposed method deals with the issues raised in the conventional protocol and improve the reliability of packets with higher BER.

Scheduling in a Cloud Environment
by Priya Govindaraj, Jaisankar Natarajan
Abstract: Efficient task scheduling plays a critical role in cloud computing environment.In this paper, we proposed a novel trust based fruit fly optimization(TFOA) algorithm for task scheduling .Even though traditional scheduling algorithms, namely First come First serve, Round Robin, Ant colony optimization and so on are used broadly in cloud computing process but still efficient scheduling is not achieved. In general cloud service provider desires to receive the customer task in a faster rate and the resource allocation to the task is to be done in a proper way. In this proposed work, tasks are allocated on the most trustworthy resource by using TFOA. Simulation outcomes show that the proposed algorithm performs better than the existing transitional algorithms like Round robin and Particle Swarm Optimization (PSO) in terms of reduced makespan and turnaround time and efficient resource utilization.

Multi-source Remote Sensing Image Big Data Classification System Design in Cloud Computing Environment
by Xuan Yue Tong
Abstract: Due to the problems of poor classification and time-consuming in traditional multi-source remote sensing image big data classification system, it cannot meet the standard requirements for image big data classification in related fields. To solve the above problems, the multi-source remote sensing image data classification system under cloud computing environment is optimized. Following the line string transmission protocol architecture, relevant information is processed, transformed and fused. Data are transported to the host through protocol transmission. Based on above principle, the system hardware and software are designed. Detailedly, designing hardware system refers to designing image sensor interface and system processing interface. The design of the system software part can be divided into two parts, including the two-wire serial protocol formulation and the image big data classification algorithm that provides users with initialization operations. At the same time, the image is sharpened and the pixels are improved. Experimental verification results show that the system has good processing effect and short time consumption.

Research and Analysis on Sensitive Data Encryption Method in Accounting Information Processing System
by Heng Li
Abstract: In order to protect the confidentiality and integrity of sensitive data in accounting information processing system, it was necessary to study the sensitive data encryption method. The current encryption method was mainly used different technology to make encryption for the sensitivity of sensitive data, which caused a problem of poor security. In order to improve the security of encryption, a hybrid encryption method for sensitive data of accounting information processing system was proposed. Firstly, the sensitive data was preprocessed. Then, based on the elliptic curve encryption mechanism, the additive and multiplicative homomorphic encryption methods of sensitive data were constructed respectively. Experimental results showed that the cryptographic running time obtained by our proposed method was relatively small and the increase in decryption computation overhead was smaller than the traditional method. Which was good to improve encryption security.
