摘要: 资源优化配置技术能够在系统执行任务之前提供合理的资源分配方案,以满足预先设定的生产目标、成本等约束条件,对于节约成本、提高经济效益具有重要意义.本文基于Petri网研究离散事件系统的初始资源优化配置问题.首先,根据Petri网的结构化特性将初始资源优化配置问题抽象为整数线性规划问题;其次,利用Lingo等软件求解初始资源优化配置问题;最后,利用实例对提出的方法进行验证.实验结果表明,提出的方法简单,高效,具有重要的实际意义.

Abstract: The technology of resource optimization allocation can provide a reasonable resource allocation scheme to meet the pre-set production target,cost and other constraints before the system performs the task,which is of great significance for saving cost and improving economic benefit.This paper studies the initial resource optimization allocation problem of discrete event systems using Petri nets.Firstly,the initial resource optimization allocation problem is abstracted into an integer linear programming problem according to the structural characteristics of Petri nets.Secondly,the software such as Lingo is used to solve the initial resource optimization allocation problem.Finally,the proposed method is verified by an example.The experiment results show that the proposed method is simple and efficient which is of important practical significance.

Key words: discrete event system, resource allocation, Petri nets, integer linear programming
