摘要
针对网格环境下影响制造资源优化配置的关键参数具有区间性的特点,基于区间数建立了资源优化配置模型,以任务完工的总成本最低为目标,将资源的价格及任务的成本限制转换为区间数,并充分考虑了资源工作时间限制以及任务时间要求,给出线性区间规划模型及其解法,并通过算例分析表明该方法的可行性与有效性.该模型在反映市场需求以及应对市场变化基础上,可得出合理的优化配置方案.
According to the characteristics of interval of the key parameters,which impact the resources optimal allocation in manufacturing grid environment,this paper establishes a model for resources optimal allocation based on interval.In order to get the lowest total cost of all task,the model changes the resource price and the cost limitation of the task into intervals,and takes full account of working hours limitation of resources and task time requirements.This paper gives the linear interval programming model and its solution,and shows the feasibility and effectiveness of the method by analyzing an example.It is concluded that,the application of the model can respond swiftly to market changes by adjusting the parameters and give a reasonable plan of resource optimal allocation
