目前中国95%的制造业都为小批量多品种柔性作业企业,传统单目标车间调度模型已不能满足企业调度要求。同时实际企业生产多为“部分柔性”生产,但目前对于柔性车间调度问题的研究大都针对于“完全柔性”车间,对“部分柔性”车间涉及较少。首先分析了经典作业问题,然后结合实际“部分柔性”生产的资源约束以及顺序约束,并引入最小提前拖后惩罚目标,建立多目标部分柔性作业调度模型,同时构建了针对“部分柔性”的约束函数。
目前中國95%的製造業都為小批量多品種柔性作業企業,傳統單目標車間調度模型已不能滿足企業調度要求。同時實際企業生產多為“部分柔性”生產,但目前對于柔性車間調度問題的研究大都針對于“完全柔性”車間,對“部分柔性”車間涉及較少。首先分析瞭經典作業問題,然後結閤實際“部分柔性”生產的資源約束以及順序約束,併引入最小提前拖後懲罰目標,建立多目標部分柔性作業調度模型,同時構建瞭針對“部分柔性”的約束函數。

Currently,95%of China's manufacturing are flexible operating companies with multi-species and small quantities,the traditional single-objective job-shop scheduling model can not meet the requirements of the enter-prise’s scheduling,while the actual production mostly are “part of flexible”production.But most studies about the flexible job-shop production are on “totally flexible”problems,little attention is based on “part of flexible”problems.This paper first analyzes the classic operating problems,then combines the request of resource con-straints and operation order constraints,introduce a function to minimize the advance or delayed penalty.Last,a multi-objective flexible job-shop scheduling mathematical model is established.At the same time,a constrain function about “part of flexible”is built.
