Assembly line balancing has been a focus of interest to academics in operation management for the last decades. Despite diverse research works in this field, many problems still remained unsolved. 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...

In this paper, we propose a mathematical optimisation model to solve the simple assembly line rebalancing problem. This problem arises when an existing assembly line has to be rebalanced in order to meet new production requirements. In this paper, a Mixed Integer Program is proposed for solving this problem with the objective to minimize the number of changes in the initial line. The computatio...

We present a new mathematical model for the assembly line balancing problem with the objective of maximizing the line comfort to operators. Besides minimizing discrepancies between the ergonomic risks of workstations, balancing is subject to temporal and spatial conditions for the workstations. To evaluate the performance of the proposed model, we compare it with other mathematical model whose ...

A wide variety of combinatorial optimization problems have been studied in recent years Of particular interest are a class of optimization problems arising from the manufacturing of vehicles on assembly lines These problems consist of sequencing the vehicles that are going to be produced such that their production is done in an e cient cost e ective manner In this thesis we introduce a real wor...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...

In this paper we consider the optimal sequencing of vehicles along multiple assembly lines We present a constraint based model of the problem with hard and soft constraints An advantage of a constraint based approach is that the model is declarative and there is a separation between the model and an algorithm for solving the model As a result once the model had been de ned we could experiment w...

In this study, a mixed model flow line sequencing problem with two objectives is considered. Mixed model flow line (MML) is known to be a special case of production lines where products are transported on a conveyor belt, and different models of the same product are inter-mixed to be assembled on the same line. We have focused on product-fixed, rate-synchronous lines with variable launching. Ou...
