Consider two independent supply chains, each consists of a manufacturer and a retailer. The distribution of demand in one supply chain is determined and known by both manufacturers. The distribution of demand in the other supply chain changes with time. We consider 3 different scenarios. In the first scenario, the two manufacturers do not cooperate. They assemble their products exclusively. In the second scenario, the two manufacturers cooperate partly, which means that they must make capacity decisions independently. But they can share their excess capacities. In the last scenario, the two manufacturers cooperate completely. They can exchange their information before installing their capacities and share their excess capacities after demands are observed. We specify the optimal capacities for both manufacturers and analyze factors affecting them in those scenarios mentioned above

A real case of route arrangement problem caused by the needs of delivering goods directly to home is discussed in this paper. Normally the route is arranged by a driver according to his experience. However, this arrangement may not be appropriate. For preciseness, an accurate distance matrix is established by performing geographical information software, PowerMap. The problem is solved by adopting a Genetic Algorithm (GA), which is carried out by using commercial software, Evolver. The result shows that the best route given by GA will be better than the driver's experience, and will save about 9% of original distance every day

Based on empirical data of twenty third-party logistic providers in America, this study adopts DEA and cluster analysis to evaluate the key factors in performance assessment. It was found that returns of scale of DMUs' status influenced efficiency ranking. The A&P model is shown useful in distinguishing efficient DMUs, while for inefficient DMUs the cross efficiency model is excellent. Empirical analysis in classification shows consistent results for factors directly correlated with logistics in both DEA and cluster analysis. While past research emphasized the importance of financial performance, this paper argues that it should take another perspective in performance assessment. This study indicates that important factors generally used in financial studies do not exhibit significant influence as expected, demonstrating a critical approach is to achieve operations efficiency rather than financial efficiency. Finally, this paper makes some recommendations to improve the operations' efficiency for logistics firms

Continuous transport systems such as belt conveyor systems are playing an important role nowadays in industrial fields of logistics, transportation, storage, etc. Condition monitoring has been an established tool and widely applied to transportation management systems. However intelligent monitoring of belt conveyor systems is still in an early stage. This paper introduces an embedded conductive detection (ECD) technology that uses a magnet matrix embedded into the conveyor belt carcass and outside sensors to detect and monitor most of the conveyor belt parameters simultaneously. As a novel nondestructive test (NDT) technology, it overcomes drawbacks of traditional conveyor belt monitoring technologies and it has characteristics of absolutely maintenance free, long lifetime, non-contact monitoring and passive measurement. In this paper, applications of the main principle of the ECD technology have also been extended to the field of automatic guided vehicles (AGVs)

Manufacturing and service processes today usually involve several process stages and operations. With an emphasis on achieving satisfactory product and service quality, using statistical methods for multistage process surveillance and fault diagnosis has become a necessity. Statistical process control methods have been widely recognized as effective approaches for process monitoring and diagnosis. However, most conventional SPC methods focus on single stage monitoring without considering the multistage scenario. In this paper we attempt to offer comprehensive references and a bibliography of statistical control methods for multistage manufacturing and service operations; evaluations with respect to existing methods are also given along with suggestions for future research topics

The issue of returns is something unavoidable and headachy for online companies. However, the effective and efficient operation of returns logistics will probably be a competitive advantage for these companies. The paper firstly gives a brief literature review, and then analyzes the returns logistics system in e-business environment. According to the level of control exercised upon the returns logistics business and the degree of third-party providers' involvement, several operating modes of returns logistics system are presented and compared in terms of customer service, cost, technology, etc. Finally, some implementing strategies of returns logistics are discussed, with the hope of providing some valuable approaches of returns logistics operation for online merchants

Convenience stores in Taiwan have had remarkable successes with retailing delivery services by integrating e-commerce and logistics systems to form a new retail delivery model: "online shopping with pick-ups at convenience stores." Though ingenious, intensified competition and increasingly complex customer behavior, it has become increasingly difficult for marketing practitioners to maintain customer loyalty. To help solve this problem, this study explores the relationships between the service quality and switching cost on choice behavior using a catastrophe model. It also applies GEMCAT II to actual market data to demonstrate the model's use in choice behavior. The present analysis shows that, service quality and switching cost are the two major factors that influence choice behavior, and that a catastrophe phenomenon can occur with a high switching cost

Producer services, which are used as intermediate inputs for the production of other goods or services, have important economic functions and implications. However, it is difficult to identify producer services from the already existing service sector classification. So, in order to overcome the analytical obstacles, and according to the intrinsic sense of producer services, but not from the perspective of specific service sectors, this paper employs the input-output method to conduct an empirical study of the growth and structural changes of China's producer services as well as their influences on China's economy and industries. Some conclusions and policy implications are drawn
