JSP是一个众所周知的NP难题。 柔性作业车间调度问题(Flexible Job-shop Scheduling Problem, FJSP)是经典JSP的拓展,该问题中每个工序允许在一组可用机器中的任何一个上进行处理。FJSP比传统的JSP更难,因为它引入了除了排序之外的另一个决策内容,即作业路径。确定作业路径意味着为每个工序决定使用哪台机器处理它。 下面是一个例子: 在这个例子中,有3个...
(Flexible Job-shop Scheduling Problem, 简称为FJSP) 是经典JSP的拓展 !!! 它与JSP最大的不同在于 FJSP允许每个工序在任何一台机器上面进行加工 除了需要对工序进行排序外 还需要决策加工该工序的机器 因此FJSP更加复杂 本文将为大家简单介绍一下FJSP问题 以及该问题在学术文献中的经典算例及其求解结果 问题简介 问...
This study investigated the flexible job shop scheduling problem considering preventive maintenance (FJSP-PM), which can be categorised into two types: FJSP-PM with a fixed maintenance strategy (FJSP-FPM) and FJSP-PM with a periodic maintenance strategy (FJSP-PPM). The objective is to minimize ...
Flexible Job-Shop Scheduling Problem (FJSP) with Parallel Batch processing Machine (PBM) is studied. First, a Mixed Integer Programming (MIP) formulation is proposed for the first time. In order to address an NP-hard structure of this problem, the formulation is modified to selectively schedule...
混合遗传算法求解FJSP柔性作业车间最优化调度问题 0、柔性作业调用问题介绍 调度问题是制造流程规划和管理中最关键的问题之一。 这个领域最困难的问题之一是作业车间调度问题(Job-shop Scheduling Problem, JSP),该问题...。JSP的典型性能指标是完工时间 (makespan),即完成所有工作所需的时间。JSP是一个众所周知的NP...
The flexible job shop scheduling problem with parallel batch processing operation (FJSP_PBPO) in this study is motivated by real-world scenarios observed in electronic product testing workshops. This research aims to tackle the deficiency of effective methods, particularly global scheduling metaheuristics...
scheduling system2. Especially, flexible double shop scheduling problem (FDSSP) that considers job shop and assembly shop is a kind of practical extension of FJSP3. Compared to FJSP where assembly-associated jobs can start only after machining is completed, FDSSP is the essential key to ...
