Abstract: Materials have very important influence on the environmental impact of the product life cycle from production to disposal and recycling. The environmental factors should be considered when product materials are selected, in order to improve the environmental friendliness of products. Due to the complexity of product material selection considering technical, economic and environmental factors, it is transformed into a decision-making problem. An integrated decision-making index system is presented, and a multi-objective decision-making framework model is established according to the index system. An algorithm integrating grey relation analysis (GRA) and analytic hierarchy process (AHP) is used to aid the decision making process. A material selection case of the housing of an electronic device is introduced, which shows the feasibility and effectiveness of the model and method presented.

Abstract: The paper concentrates on the issue of coordination and combined optimization of supply chains. All the member has its own interests, so there are conflicts between members motive and overall system objective. In the paper CAS theory is used as standard paradigm and complexity of the supply chain is analyzed. Case study includes some extreme situations of the supply chain in different levels, namely optimization and coordination problem within operation layer, business layer and enterprise layer. From the study, some rules are summarized to study the problem.

Abstract: Two-axle rotary shaping is one of advanced sheet metal forming process that combined stamping ascendant used elastic medium with traditional rotary shaping principle. The prediction model of two-axle rotary shaping is set up to predict the springback for two-axle rotary shaping. It used the back propagation neural network because of the better nonlinear mapping ability. Some of data from the experiment and FEM simulation is applied to train the network; the other data is used to test the prediction result. The result showed that the value of prediction and experiment is in good agreement, and just small error is existed. It demonstrated that the neural network model might predict the springback of two-axle rotary shaping and reduce the number of simulation calculation and experiment operation. It can offer a powerful guidance for rapid choice of process parameters in production.

Abstract: Aimed at the requirement of a project, a man-machine cooperation(MMC) manipulator was designed based on its system structure and man-machine function analysis. Meanwhile, the system functions were allocated between man and manipulator, and in order to realize information integration in MMC material handling system, a application method of mechatronics was discussed. Then an example is given to express one of the realization methods of information communication between man and manipulator.

Abstract: While logistics services have become a significant source of competitive differentiation between firms, significant challenges exist relative to developing logistics service offerings for the business customers. As a service offering, logistics services are also subject to cultural influences that exist in trade. In this article, we argue that logistics service quality (LSQ) components comprise personnel contact quality, information quality, ordering procedures, order accuracy, order condition, order discrepancy handling, order quality, convenience, agility and timeliness in context of China. This paper presents a hypothesize model of LSQ as a process.

Abstract: Manufacture cell scheduling (MCS) is a NP-hard problem, and the traditional optimization methods have their limitations when dealing with MCS. Immune algorithm that simulates the biologic immunity system is an intelligent optimization method and has potential to solve MCS. Multi-colony diploid immune algorithm (MDIA) is put forward to solve MCS. Firstly, the model of MCS is set up. Then, a typical benchmark problem is simulated with MDIA and other algorithms. Finally, simulation results show that MDIA is both effective and superior to other algorithms.

Abstract: Aviation manufacture cell scheduling is generally multi-constraint and multi-objective flexible job-shop scheduling, and is more complicated than classical job-shop because of flexible processing route, multi-restriction, multi-objective, dynamic disturb and complex model. The model of aviation manufacture cell scheduling is set up, and accordingly adaptive ant colony algorithm is brought forward. The adaptive mechanism and the genetic principle are introduced into the algorithm to accelerate convergence and avoid stagnation. Finally, the aviation manufacture cell scheduling of Xi’an Aero-Engine (Group) Ltd. is well solved by the proposed methods.

Abstract: In the process of global economy development and competition, how to strengthen the cooperation of enterprises in the supply chain environment plays a very important role to the success of enterprises. As well known, the IT technology is one of the quite essential factors to provide quicker and more accurate information for the enterprises, and therefore enhance the enterprises’ operation efficiency. In order to adapt to the supply chain (SC) environment and support for other enterprises’ common development in SC, we have to develop more powerful and unified IT technology. What is elaborated in this paper is the framework of the information cooperation system which is SC oriented. It does not deny or overthrow the legacy applications of enterprises, but to put forward a framework based on the old applications in SC. It also unifies the Web Service and references the principles of VPN. We call it the framework of Virtual Private Supply Chain Management (VPSCM). The principle, the model and the use of VPSCM as well as some other related issues are going to be explained in this paper.

Abstract: Mass customization (MC) is an emergent concept in industry intended to provide customized products through flexible processes in high volumes and at reasonably low costs. The method of configuration is one of important ways to realize quickly product customization. But, in business, particularly through the Internet, a customer normally develops in his mind some sort of ambiguity, when given the choice of similar alternative products to choose. This paper proposes an approach to product configuration according to uncertain and fuzzy requirements the customer submits to the product supplier. Finally, the digital camera is taken as an example to further verify the validity and the feasibility of the method.
