Özdeş paralel istasyonlar ve işçi kapasitesi olan bir montaj hattı dengeleme problemi

This study focuses on the balancing problem of the assembly lines in Vestel Electronics' TV production facility. TV production includes numerous tasks, and complex precedence relationships increase the problem's complexity. In assembly lines, the production is made in a given cycle time, and parallel stations can be opened to increase the line's efficiency. The tasks of the stations are performed by the workers. This study aims to assign the workers to the stations depending on their capabilities and not exceeding the cycle time of the line, and increasing the production rate by opening identical parallel stations. A mathematical model is formulated to solve the assembly line balancing problem type-1, which includes opening parallel stations and assigning the workers to the stations based on worker skills. Moreover, company-specific constraints are added to the model to satisfy the production conditions. Depending on the company's requirements, an alternative meta-heuristic algorithm is developed to receive more rapid solutions than the mathematical model. Computational experiments show that the developed algorithm can be used as a decision-support tool to satisfy the production metrics.
