Owing to the randomness of the job release time, it is not possible to obtain all job information in real time during the operation of a manufacturing system. Generating a suitable scheduling strategy at the correct moment is the focus of addressing this disturbance. In this study, the flow time of the job in the manufacturing system was used as a...

Process planning and scheduling decisions are independently performed in a manufacturing system in traditional approaches. Integration of these two decisions provides significant benefits such as enhancing the productivity of manufacturing resources, lead time reduction, and decreasing total production costs. An approximately 10% improvement has be...

The objective of the research is to solve the flexible job shop scheduling problem (FJSP). In this paper, the new algorithm is proposed mainly based on discrete concepts of the differential evolution (DE) algorithm with the new idea called the fuzzy machine selection approach. In the first step, the initial population is created by using a set of t...
