In this paper, first we study the kanban systems; then we analyzes the models of kanban systems, include simulation models and Markov chain models ; finally, we develop a mathematical optimization model that addresses a mufti-item, mufti-stage network for application to general supply chain systems. The dual-type kanban control system is adapted to plan and allocate production and delivery throughout the supply chain system. The objective is to minimize the operating cost and inventory holding cost.展开更多

However, Prolog is not suitable to develop many kinds of components, such as data acquisition and task scheduling, which are also crucial. To make the best use of the advantages and bypass the disadvantages, it is attractive to integrate Prolog with programs developed by other languages. In this paper, an IPC-based method is used to integrate backward chaining inference implemented by Prolog into applications or embedded systems. A Prolog design pattern is derived from the method for reuse, whose principle and definition are provided in detail. Additionally, the design pattern is applied to a target system, which is free software, to verify its feasibility. The detailed implementation of the application is given to clarify the design pattern. The design pattern can be further applied to wide range applications and embedded systems and the method described in this paper can also be adopted for other logic programming languages.展开更多
