基于模糊综合评判的实际生产调度决策研究

为解决实际生产调度中的模糊不确定性决策问题,提出了基于优先级规则和模糊综合评判结合的生产调度决策方法.通过分析实际生产调度中的任务分派过程,得出任务分派时需要考虑的任务影响因素以及设备影响因素.利用影响因素的隶属函数表示各影响因素的优先程度,解决了调度过程中的不确定及偏好信息的表示问题.通过模糊综合评判计算,对任务优先级和设备的优先级进行综合计算,解决了调度过程中多模糊因素综合权衡问题.最后通过算例对该方法计算过程进行说明,并以实际车间调度应用为例分析了该方法的实用性.

Research on the Practical Production Scheduling Decision Based on Fuzzy Synthetic Evaluation

In order to deal with the decision-making ambiguity in practical production scheduling, this paper put forward a decision-making method based on the combination of priority rule and fuzzy synthetic evaluation. Through analysis of the task assignment process in practical production scheduling, the influencing factors relevant to task priority and machine priority were found. By using membership function to express the priority degree influencing factors, the problems of representing uncertainty and preference information in practical shop scheduling were solved. With fuzzy synthetic evaluation calculation aiming at computing the priority degree of tasks and machines, many problems in synthetic tradeoff were solved successfully. Eventually, examples were utilized to explain the calculation process of this method, and practical shop scheduling was applied to analyze the feasibility of this method.
