The Balance of Mixed-Model U-Shaped Assembly Line Based on A Fuzzy Goal Programming

Assembly line balancing is attached to great significance in terms of improving the assembly efficiency and cutting down the assembly cost, Business tends to adopt a mixed assembly line to satisfy the customers´ demands and reduce the costs nowadays, while in the actual productive process, productive activities are often influenced by some uncertain (ambiguous) factors, and end up in vague surroundings. Assembly line balancing generally requires a set of acceptable solutions to the several conflicting objectives. This paper addresses the existing problem in the balance of a mixed-model U-shaped assembly line and proposes a fuzzy goal (the number of workstations and cycle time goals) programming model. Moreover, the numerical example further tests and verifies the validity and feasibility of the proposed approach.
