The impacts of system neglect effect on emergency resource replenishment
by Zhiru Juan, Weidong Huang, Haiyan Wang, Jie Cao
Abstract: Aiming at preparedness and response to emergency events, this paper studies emergency resource replenishment decisions made by an irrational decision maker. The decision maker would exhibit system neglect effect, in the sense that the decision maker reacts primarily to signals they received and secondarily to the underlying system that produced the signals. By comparing the performances of threshold methods and smoothing strategies, we identify the impacts of system neglect effect on the resource replenishment decisions and offer insight into when high-consequence, low-probability events may occur. The results show that threshold method is more attractive than smoothing method in emergency management and the existence of system neglect may improve the efficiency of the replenishment decisions generated by smoothing strategies. The findings are meaningful to preparedness and response to emergency events and help manage the influence of system neglect effect when replenishing emergency resources.
Keywords: forecasting; system neglect; smoothing strategy; threshold method.
MBAN-MLC: a multi-label classification method and its application in automating fault diagnosis
by Shijun Chen
Abstract: With increasing competition in the mobile telecom network market, the network quality becomes one of the key factors for competitions between network operators. At the work site of drive-testing in the mobile radio communication network, drive-testing experts needed to tag the fault causes manually based on their experience for fault diagnosis, and there were always multiple causes. Traditional single-label classification method cannot be used here to automatically tag the multiple fault causes. In this paper such kind of fault diagnosis problem is transformed to the multi-label classification problem, and a multi-label classification method (MBAN-MLC) is proposed for fault diagnosis automation. MBAN-MLC is based on a Bayesian network-augmented Na

Dynamic Data Source Selection for Humanistic Culture Integrated Information Retrieval
by Song Deng
Abstract: There are hundreds of data sources in tourism, and the quality of data in data sources is quite different. How to obtain high-quality integrated information from a few data sources has become an important research direction, so the technology of data source selection arises at the historic moment. One of the core technologies of data source selection is to construct data source summary. When the data source content updates, it will inevitably lead to changes in the data source summary. The calculation work load to completely update the summary is huge, so a partial update strategy is used to improve the efficiency. In order to enhance the efficiency of tourism cultural information integration, we propose a new dynamic data source selection strategy. Firstly, we build a data source summary based on the relationship between people and characteristic words. Then, We design a local summary updating algorithm based on sampling technique. Finally, we propose a scoring method of data source base on the gain of cultural content of a single or synthetic character for integration purposes. We conduct a number of experiments based on field data collection, and the results showed that compared with the existing update algorithms, our method has higher accuracy. Therefore, it can provide effective support to character or attraction integration.

Railway route optimization from Romania to Poland based on an analysis of Chinas "One Belt and One Road" initiative
by Yang Wang, Xiaochun Lu
Abstract: With the proposal of the "One Belt and One Road" initiative, a new strategic route is underway. It travels from China to Afghanistan, Iran, Turkey, Romania, Poland, and Western Europe. This is a new rail route, and the exact path is unknown. This paper focuses on the railway route between Romania and Poland. Railway lines between two countries can be two different gauge rails, which can lead to transshipment problems. A dynamic programming model is established to find optimized railway routes between these countries. In the optimization model, the transshipment stations on country borders are set as constraints. First, four shorter routes from the hundreds of railway lines are obtained by the Dijkstra-based dynamic programming algorithm. Next, by accounting for the transit service abilities of railway stations, we estimate the total transportation time using Monte Carlo simulations. Finally, we obtain the two best routes. The first one passes Bucharest, Nevetlenfolu, Brest and Warsaw, and the second route is from Bucharest, Nevetlenfolu and Medyka to Warsaw. However, these two routes are not the shortest paths. We found that the line from Bucharest to Nevetlenfolu is the common section of two routes. The Nevelenfolu railway station may become a bottleneck of the two routes. Therefore, future upgrades of the Nevetlenfolu railway station will be vital. At present, these railway lines have not played role in trade between China and Europe, but they may become important transportation lines in the future.

by Jianjun Wang, Lei Zhou, Fachao Li
Abstract: The two-stage delay distribution problem is a class of special programming problem. In real life, the supply, demand and transportation environment are with uncertainty. If the random customer demand dose not reached full load, we will choose the decision of the delay delivery or delivery on schedule based on minimize expectation cost. In this paper, based on the analysis of the random distribution characteristics and deficiencies, a class of two-stage delay distribution stochastic programming model with compensation mechanism is put forward. Through synthesizing the expectation, variance and probability distribution of cost factors, stochastic programming model can be converted into a class of crisp programming models. Finally, combined with the case of the vehicle distribution, using the analytical method, the proposed model is applied to get the optimal solution which can reduce transportation costs and improve the profitability.

Modeling and Improvements of Production Processes using OptQuest and Process Analyzer
by Salih Aka
Abstract: Simulation models are methods that show the development opportunities in existing systems, and determine the performance difference between existing and desired systems. In a simulation model, the model must be structurally reconstructed or the parameters changed to see the difference between the first and after stages. However, alternative situations can be evaluated with Process Analyzer and OptQuest without the need to reconstruct the system. The Process Analyzer provides the running and comparison of alternative scenarios built by changing variable and parameter values in a simulation model. OptQuest module is an optimal search simulation tool that looks for the best solution through input variables and constraints to serve objective functions of the model. The aim of this study is to show that Process Analyzer and OptQuest can be used in improving of production processes. Process Analyzer and OptQuest provide computational simplicity with their user-friendly interfaces in improving production processes. According to current production process simulation model, a large number of iterations are performed in the direction of resource and capacity constraints through OptQuest and Process Analyzer, and the results that provide the best performances are determined. Finally, the best response values are achieved when the number of package maker (PM) and capacity of package are two.

Wolf Pack Algorithm for Optimization of Cutting Parameters in WEDM using Taguchi Method
by Yanqiu Xiao, Wuyi Ming, Dili Shen, Wenbin He, Jun Ma, Jianqiang Jiao
Abstract: The optimization of cutting parameters for Wire Electrical Discharge Machining (WEDM) is one the most difficult combinatorial optimization problems, due to their complicated, coupled, and nonlinear nature of the input-output variables of them. An exact solution for a WEDM optimization 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 Optimization (PSO), Wolf Pack Algorithm (WPA), etc.). The objective of this paper is to develop a robust approach using WPA to obtain the optimized 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 optimizing 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.

Coordination of production scheduling and vehicle routing problems for perishable food products
by Xueli Ma, Shuyun Wang
Abstract: This paper considers the integrated optimization of production scheduling and vehicle routing problems for perishable food products under a manufacturer-retailer supply chain model. Considering the perishable characteristics and randomness of market demands and delivery time, an integer nonlinear programming model is constructed. Combining an improved genetic algorithm(GA) and a random simulation algorithm(RA), we design a hybrid GA-RA algorithm. To validate the proposed model and the algorithm, a case problem of a catering service company and some different sizes of test examples from Solomons problem set are analyzed. The results show that arranging the production order and vehicle route simultaneously can significantly improve both the freshness of perishable food products and the customer service level. The proposed hybrid algorithm can obtain stable optimal solutions within a limited period of time for different sizes of such problems.

by Yuhan Wang, Wenbing Wu, Shuxiang Wang
Abstract: Agricultural products logistics is of great significance to regulating the supply and demand, protecting the income of peasant households and increasing the added value of agricultural products. The agricultural products logistics in China has the characteristics of long chain, multiple nodes and many influencing factors, which makes it difficult for the government and enterprises to find the effective focus of resource allocation. In view of this situation, this paper summarises 13 key factors that affect the development of agricultural products logistics in China on basis of the connotation of agricultural products logistics, in combination with actual development and expert opinions. Then, the paper establishes five-level hierarchical structure of those factors in the use of interpretive structural modelling (ISM), which intuitively reflects the hierarchical association among the influencing factors. Finally, according to the five-level hierarchical structure, this paper puts forward targeted development suggestions for relevant departments and enterprises.

The production strategy for two products considering stochastic demand under cap-and-trade regulation
by Hua He, Changsong Ma
Abstract: This paper deals with a production model involving one manufacturer who produces two products. One product adopts green technology and we term the product as 'green' product, and the other product, with regular production technique, termed 'regular' product. In this paper, we formulate models to examine the impact of production for two products under cap-and-trade policy. Analytical results are obtained: with cap-and-trade policy, the manufacture's maximum quantity for product 1 and product 2 is lower than the case without carbon emission constraint, and the expected profit of the manufacturer under this situation depends on initial allowance. To cope with the increasing awareness of environmental protection, firms are required to apply some green technologies to produce 'greener' products. General economics concepts are achieved. That is, the green technology input could improve the manufacture's normal product quantities and expected profit to some degree.
Keywords: two products; cap-and-trade; stochastic demand; production strategy.
Enabling cutting tool services based on in-process machining condition monitoring
by Guohai Zhang, Huibin Sun
Abstract: The cutting tool industrial product-service system (ct-iPSS) integrates intangible cutting services with physical cutting tools to satisfy consumers' cutting/machining requirements. It realises a win-win situation for cutting tool service consumers, cutting tool manufacturers and the third-party cutting tool service providers. However, the study on ct-iPSS is insufficient when some significant topics are still pending. In this paper, the in-process cutting tool condition monitoring service is integrated in the improved ct-iPSS model. A more precise cutting tool demand prediction service is enabled on the basis of in-process cutting tool reaming useful life prediction service. The used cutting tool collection routes are optimised together with the new cutting tool delivery routes. The total delivery/collection cost is minimised systematically to enable a more feasible ct-iPSS. A scenario is presented to verify these services. The ct-iPSS's feasibility and practicality are enhanced by the improved ct-iPSS model.

A novel improvement on rank reversal in TOPSIS based on the efficacy coefficient method
by Houxing Tang, Fang Fang
Abstract: Some papers present a simple and intuitive method for eliminating rank reversal in TOPSIS by replacing the relative ideal solution with the absolute ideal solution. Unfortunately, this method has some defects, because it creates new constraints on the initial data. Consequently, it will still result in rank reversal. However, these new constraints are neglected in the present studies. In this paper, the efficacy coefficient method is introduced to deal with these problems. Firstly, the merits and drawbacks of the absolute ideal solution are presented. Secondly, the efficacy coefficient method is used to restructure the initial data in order to eliminate these new constraints. Thirdly, it is proved that selecting a different preference weight coefficient in the efficacy coefficient method does not affect the relative rank, and can increase the discrimination degree of alternatives. Finally, based on an illustrative example, the results show that the novel improved method is valid and stable.
Keywords: TOPSIS; rank reversal; efficacy coefficient method; ECM; novel improvement; multi-criteria decision-making.

by Shiqi Wen, Cheng Wang, Haibo Li
Abstract: Aiming at the problem that the general Bayes classification model cannot be applied to regression prediction, a Naïve Bayes regression model is proposed. Firstly, in order to simplify the complexity of model, attribute values and decision values are discretised from continuous value to discrete value. By summing the probability of Bayesian classification and using the mathematical expectation value as the regression value, the process of regression problem is turned into a classification problem and the Naive Bayes classification model was modified into Bayesian regression model. The difference of input attribute values, output values, application scope, requirement of output values, operation to obtain output values between Naïve Bayes classification model and Naïve Bayes regression model is compared in detailed. Secondly, the Naïve Bayes regression model is application in collaborative filtering recommendation. This study identifies the user and the item as independent attribute characteristics, while rating as the classification category. And the attribute values and category values are discretised to simplify the complexity of Naïve Bayes regression model. The experiment results on Movielens-100k, Eachmovie and Jester data set show that this new method has high success rate and efficiency.

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.

by Jianjing Jin, Yibing Li, Donglin Song, Lei Wang
Abstract: Abstract: Calibrator plays an important role in the shaping of the cooling in the plastic profile production. In this paper, a simplified model with the specific length was used as the analysis example. The multi-objective optimization for the water channel position of the model was carried out based on the modern intelligent algorithm. In order to realize the uniform distribution of the surface temperature of the profile, the position parameters and the diameter of the cooling water channel were taken as the design variables. Then Kriging model was established on the basis of Latin hypercube sampling, and the above variables were optimized based on NSGA-II. Finally, the optimized channel parameters were obtained. Compared with the initial scheme, the temperature distribution of the profile surface was uniform. Finally, the effectiveness and applicability of the design method of the chilled water channel parameters of the calibrator based on NSGA-II were verified.

Mining QoS benchmark of resource-service chain for collaborative tasks
by Haibo Li, Yafeng Gao
Abstract: To improve the efficiency and quality of resource services selection in collaborative task systems, the temporal relationship between the resource services should be taken into account. At the same time, the changing market requires a dynamic selection benchmark. QoS (Quality of Service) as the main basis for the selection of resource services, mining the business data set to develop the QoS benchmark has a good objectivity and dynamic. Taking Manufacturing as a typical collaborative process, based on the resource service chain (RSC, Resource Service Chain) formed by the scheduling order of resource services, an approach called the QoSB-RSC (mining method for QoS Benchmark of RSC) is proposed to obtain the QoS benchmark of RSC. By comparing the QoS similarity between scheduling instances of RSC, mining the cluster centers from business data set as the QoS benchmark. The performance of the QoSB-RSC is verified by experiment and case analysis, indicating that it has positive significance to improve the efficiency and quality of resource services selection.

Testing Job Characteristics Model: Empirical Research on Service-Oriented Organizations in China
by Xueliang Pei, Yang Yang, Yingying Su, Longfang Xue
Abstract: In service-oriented organizations, employees job characteristics and motivations are important to improving organizational performance. The job characteristics model is a classical model that links job characteristics, job motivation, and organizational performance; however, theoretical and empirical research on this model is insufficient. Therefore, a theoretical model of relationships among employees job characteristics, job motivation, and work outcomes is proposed. We took service-oriented organizations in China as our sample and conducted empirical research on data from 209 valid samples. The results showed the following: (1) job autonomy and task significance positively affected personal outcomes, and skill variety and job autonomy positively affected work-related outcomes; (2) skill variety, job feedback, and task significance were positively related to inner psychological needs, while skill variety, job autonomy, and task significance were positively related to work interest; and (3) job motivation had different mediating effects on the relationship between employees job characteristics and work outcomes.

Resource Selection Method Based on Service Capability in Cloud Manufacturing
by Zhuling Zhang
Abstract: The cooperation among enterprises becomes more popular than before as the manufacturing industry tends to be globalized. How to transform a production-oriented manufacturing industry to a service-oriented one still remains a problem. Cloud Manufacturing, which is a new manufacturing model based on the network, responds to the proper time and conditions. It collects unevenly distributed physical manufacturing resources of the world into virtual resources and provides services outward by providing services. When a large number of resources accumulate, it is difficult to select optimal resources objectively and a good resource selection method is needed. Service capability is the attribute of resources to provide external services. It represents performance indicators of resources or user's evaluation of resource services. It plays an extremely important role in measuring the quality of resources. This paper performs analysis in two contexts: the business system and manufacturing process. It uses workflow log mining technology to provide a favourable environment for resource selection. The paper proposes a resource selection method based on service capability and applies it to experimental analysis of a citys the research and development project named manufacturing service platform for small and medium-sized enterprises. The results show that the method proposed is feasible.

Abstract: In order to solve the evaluation problem of cloud manufacturing service and then minimize the time of choosing the best service, a comprehensive evaluation index system of cloud manufacturing services is constructed in the light of the characteristics of cloud manufacturing service. The service attributes, manufacturing attributes and network attributes are taken into account from two views of the online characteristics and the offline characteristics of cloud manufacturing service in the evaluation index system. And on this basis, a quantitative evaluation model based on modular neural network (MNN) is proposed. Firstly, the clustering algorithm subtractive-k-means is introduced and used to divide the task into several subtasks based on the idea of modularization. Then, the subtasks are processed through the trained BP network. Finally, the self-adaptive genetic algorithm is used to optimize the integration weights of each subtask processing module. Combining with the cloud manufacturing evaluation index system, this modular neural network model can be used to effectively evaluate the cloud manufacturing service and help customers quickly select the best cloud manufacturing service.

User-based collaborative filtering algorithm fusing the local and global nearest neighbour
by Cheng Wang, Shiqi Wen, Fangfang Su, Yewang Chen, Yiwen Zhang, Guoqi Zheng
Abstract: Collaborative filtering method is one of the most successful used recommendation algorithm. It can be divided into the global nearest neighbour based method and the local nearest neighbour based method. The global neatest neighbour based method has high stability but the recommended results are not sufficiently personalized. The local nearest neighbour based method is more accurate and personalized than the global neatest neighbour based method, but the prediction failure rate is high and its not stable. Aiming at these problems, a new user-based collaborative filtering algorithm fusing the local and global nearest neighbour is proposed. Firstly, the max-min K-medoids clustering algorithm is applied for clustering items into several clusters. The local similarity of users is calculated in each item cluster. Secondly, the factor of correlation-weighted is introduced to improve the accuracy of the global similarity among users. By using the contribution proportion of the nearest neighbour as fusion weights, the global similarity and the local similarity are fusion as the new similarity measurement and the nearest neighbour can be found in this new similarity measurement. Finally, this new similarity among users is presented to optimize the selection of neighbours of target user. The user-based collaborative filtering algorithm fusing the local and global nearest neighbour increases the recommendation precision while avoiding the shortcoming of instability. The experimental results on EachMovie and MovieLens-100K show that the prediction reliability and accuracy of this new method are better than traditional ones.

Abstract: A humanoid head robot system with some specific expression was comprehensively modelled in this paper by interactive visual expression analysis between the operator and the robot. Firstly, based on the open source hardware of Fritz humanoid head robot, an integrated emotional expression mapping model was proposed by extending the functional module of voice, vision and so on. Secondly, to achieve a natural interaction between the expression robot and the operator, the integrated visual analysis is mainly utilized for emotion calculation. Haar-like featured cascade classified algorithm is utilized for automatic face location. Gabor feature is filtered and down-sampled as the emotional expression feature. To deal with unreasonable samples distribution in traditional Eigenface, an optimized eigenvectorss selection is built by comparing projection reconstructed images with original image. Finally, the classification of with-in class PCA with energy dimension is served as expression recognition. The experimental results on JAFFE database and real-time video image demonstrate the feasibility and effectiveness of the proposed modelling scheme.

by Xianbang Yang, Ting He
Abstract: In the modern manufacturing system, process planning is an essential function. Generally, a part has many alternative process plans since there are many other viable processing methods and techniques. Therefore, optimization of the process plan in manufacturing is an important task of flexible process planning. In this paper, the flexible process planning method based on firefly algorithm is developed for improving production efficiency and reducing production cost. Firstly, a hierarchical evaluation index system for the process plan is presented and a multi-objective nonlinear optimization model of process planning is formulated. This model is based on the evaluation index system in which the quality, cost, efficiency, and environmental consumption of parts processing can be optimized. Next, the improved firefly algorithm is proposed to solve the multi-objective nonlinear optimization model. Finally, an example is given to prove the validity of the model and algorithm.
Keywords: flexible process planning; multi-objective; optimization; firefly algorithm.
