Mixed-model assembly line, reconfiguration, feeding lines, family, delivery deviation, pareto optimalAbstract
A mixed-model assembly line is a type of assembly line where various products with common basic features are assembled. Accordingly, this study aims to investigate and analyze the requirements and challenges of reconfiguring mixed-model assembly lines in the presence of sub-lines. In this paper, an optimization problem related to sequencing in a mixed-model assembly line is examined. Reconfigurable systems are designed around families of similar products. A mixed-model assembly line requires reconfiguration after assembling each batch of products within a family. The main objective of this research is to optimize the sequencing process in mixed-model assembly lines, which presents unique challenges due to the high variety of products and the need for rapid changes in the lines. To address these challenges, products have been categorized into different families based on commonality and complexity indices. This categorization is aimed at reducing the time and costs associated with reconfiguring the lines after assembling each product family. This optimization problem is solved by using Pareto-optimal solutions, which represent the optimal sequence of products within each family.
