虚拟企业资源调度的灰色机会约束规划

Grey Chance-constrained Programming in Virtual Enterprise Resource Scheduling

虚拟企业运营中,存在许多不确定因素,在资源调度时,必须考虑这些不确定参数。该文考虑系统具有灰参数的情况,提出一种灰色不确定规划模型,由于模型不能直接转化为确定型规划求解,因此该文提出灰色模拟技术,结合遗传算法,给出了求解步骤与方法,通过计算实例,结果表明模型适用,方法正确有效。

The situation is naturally uncertain in virtual enterprise so that people must consider uncertain parameters to manage resource distribution.In this paper,an uncertain programming model,focusing on grey parameter of programming,is proposed.The model is so complicated that people have to use genetic algorithm to resolve it.For the purpose of dealing with grey Chance-constrained a method named grey simulation is suggested in detail.This paper studies on an example and compare s it with traditional method.The results prove that the model is correct and the method is effective.
