Model to determine Optimization number of work stations and balancing line by using genetic algorithm in the saipa company

Given the importance and attractiveness of the mixed product parallel lines balancing problem and the importance of the human factor in the development process and also very few studies in relation to several simultaneous objectives that is a new approach in the field of parallel assembly lines, this paper presents a two-objective combined integer mathematical model for balancing mixed-model parallel assembly lines. Because of the complexity of the problem is in the class of NP-hard problems, the mathematical model can’t be solved for the actual dimensions of the industry. Genetic algorithm was used to solve this problem, coding and designing is done with MATLAB. The proposed model is evaluated by data set provided in this area. Results reflect the good performance of the model and improved objectives. Therefore proposed model leads to reduce the number of stations required in lines and minimize the total cost of human resources in mixed model parallel assembly lines.
