As Ag ile Supply Chain System (ASCS) is dynamic and distributed, the realization of it ’s processes needs to be much flexible. Often in Agile Supply Chain System (ASCS ), there are many dynamic tasks, many changes of the processes, and cooperative workflows, which need the workflows able to be adjusted agilely and smoothly, no t much affecting others. This paper will propose a flexible workflow management for achieving the agility and compatibility. At the first of the paper, we will discuss the situation in which Agile Supply C hain System is applied, and then we will elaborate the characteristics of Agile Supply Chain System. So with that, the shortcomings of the process managements t hat are, at present, used in Supply Chain Systems will be displayed clearly. The n, the proposal will be given in the paper, to resolve the problems in the prese nt process management in ASCS. We will see supply chain systems implemented mult i-agent-based technology to adapt to the dynamic environment, however in many systems, coordination of the workflows is executed by the explicit messages comm unicated between the agents. This will lead to a tightly coupled system. To over come it, the paper suggests the workflow management in agent-based ASCS using t he Events-Triggering mechanism, instead of the explicit messages. We create Eve nts-Triggering contents and rules, having push-pull mechanism, event-state se t and triggering-conditions, and store them in the distributed database subject ed to the corresponding agents. Adjusting the Events-Triggering data will be us ed to adapt to the dynamic tasks and the changes of processes. In sum, we will p resent the methods of process modeling, the system structure, and the executing -mechanism of the flexible workflow management we propose in the paper. Also, t he paper outlines several exception-handling policies for the flexible workflow management, in succession. And at the final of the paper, we discuss the realiz ation of the flexible workflow management in Agile Supply Chain System. The flex ible workflow management will be implemented using CORBA services and Java techn ology for the distributed systems. CORBA is chosen as the specification of distr ibuted electronic data exchange, and Java as the construction tool of the system . The framework of the flexible workflow management constructed on them is showe d in the paper.展开更多

One of its implements is establishing a virtual ente rprise (VE) around the task, where each manufacturing unit, or sub-task, probab ly have at least one resource, or referred to as suppliers. Because each manufac turing unit might be carried out in different geographical places that implies t his probably gives rise to transportation cost, the selection of resources for e ach manufacturing unit must considers not only the manufacturing price of each r esource but also the transfer cost between any two potential resources. This pap er discusses the resource reconfiguration problem with two hypotheses: 1. Permit s one or more resources to attend the same manufacturing unit as long as the tot al cost can reach its least; 2. The freight contains the initial part, that is t he freight concave. Indeed, these hypotheses are much meaningful in the real wor ld. Furthermore, to simplify the solution for this problem, we propose two conce pts: assembly tree (AT) and combinatorial mode base (CMB). Formally an AT is a c omplete production line, which can ensure the parts equilibrium, and its capacit y is subjected to the least capacity of every resources and every path in it. In the end, we propose an implicit enumeration algorithm (IEA) by the use of CMB, including it is a heuristic algorithm for integer programming (HAIP) by the use of AT. The IEA can be outlined that for a determined combinatorial mode, if it h as not enumerated, we use the HAIP to get an near optima and corresponding CMB, marking every combinatorial mode extended from the CMB as enumerated, other cont inue a new iteration. The HAIP can be outlined that for a determined combinatori al mode, there are some determined number of AT, we select an AT with the le ast slope, and select the volume of this AT to its ultimate within its capacity, iterates this doing until the needed volume reached. In the end, we conclude th is paper and prospect the deep research based on GA thought.展开更多

There is a common opinion that applying multi-agent collaborative work environm ent is an appropriate method to solve agile supply chain management problem. We have presented a model based on coordination of Multi-Agent System (MAS) two ye ars ago, and it has already been proved to be a rather better model by practical project. In the model, we apply MAS structure, and agents negotiate each other to achieve coordination, so the communication among agents becomes very impo rtant. Task allocation is a very common problem in agile supply chain management, and t here are many complex task re-allocation problems at the transaction level. In such situations, agents need to negotiate with others to produce effective alloc ation results. But traditional negotiation mechanisms often cease to work as a r esult of communication or computational complexities. Auctions provide an effici ent way of resolving one-to-many negotiations, so in this paper, we choose Eng lish auction to design a sufficient negotiation mechanism, and use combinatorial auction to solve the complex task re-allocation problems. We first analyze the features of task allocation problems in agile supply chain and build a problem model, and then design a comprehensive task allocation mechanism based on auctio n theories. Finally, by examining our results for what it is, essentially, an ap plication of game-theory and mechanism design to existing application, we draw some general conclusions on how such concepts can be operationalized in automate d agents. Some further research on the problem is also discussed.展开更多

Therefore the subjects regarding trust have become important. Trust established in Supply Chain causes effective relationships among definitive numbers of suppliers in the long-run. The effect of trust in supply chain on firm performance and the contribution of agility to this relation have been supported in the literature. In this research, the role of agility in the effect of trust in supply chain on firm performance will be investigated. According to the results of hypotheses tests, there are positive and significant relations between supply management integration and trust in supply chain, between trust in supply chain and supply chain agility, and between supply chain agility and firm performance.展开更多

This model is based on the literature review about the four supply chain management paradigms and also performance measurement systems. This paper contributes to the literature by introducing a new model to improve the leanness, agility, resilience, and greenness of manufacturing supply chains. Among the suggested LARG practices, the ones influencing more the supply chain performance are the just in time and also the supplier relationships. Also the supply chain performance measures with more LARG practices influencing them are the inventory levels and the time, that is, the supply chain＇s operational performance is the most affected by the simultaneous paradigms deployment in the supply chain.展开更多

文摘The main objective of this paper is to propose a conceptual model about the influence of lean, agile, resilient, and green （LARG） practices on supply chain operational, economic and environmental performance. This model is based on the literature review about the four supply chain management paradigms and also performance measurement systems.
