A model of a re-entrant line, consisting of the bottleneck workcenter and time delays representing other workcenters, is considered. Its mathematical description is provided and performance metrics are introduced. The steady states of this model and their stability properties are investigated under two dispatch policies—first buffer first served (FBFS) and last buffer first served (LBFS)—and under...
Traditional formal method has been solved the problems of functional modeling and verification of Web service composition, but it could not effectively analyze and calculate the costs of the service composition. A minimum cost composition algorithm based on process algebra CSP is proposed. The algorithm first translates the XML format Web service composition description to CSP format formal description...
Cluster supply chain is a complicated network structure, the enterprises in it not only have to coordinate with enterprises in the same single chain, but also have to compete and cooperate across chain. In this paper we study mainly on how core manufacturers in different single chains cooperate and compete with each other, in order to realize the minimal cost under the premise of cluster supply chainpsilas...
It is an ideal choice of establishing the simulation of the Automatic Storage&Retrieval System (AS/RS) for predicting cost and increasing efficiency. In this paper, Flexsim is used to build up an AS/RS system model for simulation and optimization. Firstly, the overall process and simulation modeling are described in detail based on Flexsim. During analysis of the model, this paper focuses on the...
This paper demonstrates the linkage between logistics system simulation and teaching mode, and explores new teaching methods and teaching ideas. It puts emphasis on analyzing the application of logistics simulation technology in the logistics system and exploring appropriate teaching modes of logistics system simulation. We make a point of the application of logistics system theory knowledge and the...
