    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 summarizes 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 5-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 5-level hierarchical structure, this paper puts forward targeted development suggestions for relevant departments and enterprises.

  • The Production Strategy for 2 Products Considering Stochastic Demand under Cap-and-Trade Regulation   Order a copy of this article
    by Hua He, Changsong Ma, Zhenyu Luo, Xiangchao Liu 
    Abstract: This paper deals with a production model involving 1 manufacturer who produces 2 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 2 products under cap-and-trade policy. Analytical results are obtained: With cap-and-trade policy, the manufactures 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 manufactures normal product quantities and expected profit to some degree.

  • Enabling cutting tool services based on in-process machining condition monitoring   Order a copy of this article
    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 realizes 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 service is enabled on the basis of in-process cutting tool reaming useful life prediction service. The used cutting tool collection routes are optimized together with the new cutting tool delivery routes. The total delivery/collection cost is minimized systematically to enable a more feasible ct-iPSS. A scenario is presented to verify these services. The ct-iPSSs 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   Order a copy of this article
    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 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; novel improvement; multi-criteria decision-making.

  • The impacts of system neglect effect on emergency resource replenishment   Order a copy of this article
    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

    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.

    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • User-based collaborative filtering algorithm fusing the local and global nearest neighbour   Order a copy of this article
    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.

    by Guoliang Zhang 
    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.
