Multiobjective Fuzzy Mixed Assembly Line Sequencing Optimization Model

الملخص EN

It can be deduced from previous studies that there exists a research gap in assembly line sequencing optimization model for mixed-model production lines.

In particular, there is a lack of studies which focus on the integration between job shop and assembly lines using fuzzy techniques.

Hence, this paper is aimed at addressing the multiobjective mixed-model assembly line sequencing problem by integrating job shop and assembly production lines for factories with modular layouts.

The primary goal is to minimize the make-span, setup time, and cost simultaneously in mixed-model assembly lines.

Such conflicting goals arise when switching between different products.

A genetic algorithm (GA) approach is used to solve this problem, in which trapezoidal fuzzy numbers are implemented for variables such as operation and travelling time in order to generate results with higher accuracy and representative of real-case data.
