In this study, we consider an assembly line rebalancing problem. We assume that there is a disruption on one or more workstations that makes the current solution infeasible. After the disruption, we aim to find a rebalance so as to catch the trade-off between the efficiency measure of cycle time and the stability measure of number of tasks assigned to different workstations in the original and new solutions. We generate all nondominated objective vectors with respect to our efficiency and stability measures. We develop two optimization algorithms: classical approach and branch and bound algorithm. The results of our experiments show the favorable behaviors of both algorithms and superiority of branch and bound algorithm.

Two-sided assembly line balancing models and heuristics
Arıkan, Uğur; Kırca, Ömer; Department of Industrial Engineering (2009)
This study is focused on two-sided assembly line balancing problems of type-I and type-II. This problem is encountered in production environments where a two-sided assembly line is used to produce physically large products. For type-I problems, there is a specified production target for a fixed time interval and the objective is to reach this production capacity with the minimum assembly line length used. On the other hand, type-II problem focuses on reaching the maximum production level using a fixed assem...
Workload smoothing in assembly lines
İmat, Sadullah; Azizoğlu, Meral; Department of Industrial Engineering (2014)
In this thesis, we consider a simple assembly line balancing problem with fixed number of workstations and predefined cycle time. Our objective is to minimize the sum of the squared deviations of the workstation loads from the cycle time. We first present pure integer nonlinear programming model and then convert the model into mixed integer linear program. We develop several optimality properties and bounding mechanisms, and use them in our branch and bound algorithm. The results of our computational study ...
Rebalancing the assembly lines: exact solution approaches
Sanci, Ece; Azizoğlu, Meral (2017-01-01)
In this study, we consider an assembly line rebalancing problem with disruptions caused by workstation breakdowns or shutdowns. After the disruption, we aim to find a rebalance so as to catch the trade-off between the efficiency measure of cycle time and stability measure of number of tasks assigned to different workstations in the original and new balances. Our aim is to generate all nondominated objective vectors with respect to the efficiency and stability measures. We develop two optimisation algorithms...
Rebalancing in assembly lines
Girit, Utku; Azizoğlu, Meral; Department of Industrial Engineering (2019)
Assembly line balancing is an important and well recognized operations research problem. The current balancing might not stay optimal for a long time due to the changing conditions. The changing conditions, like disruptions in one or more workstations, may cause some inefficiencies, even infeasibilities, for the current balance. In this study, after the disruption, we aim to rebalance the assembly line by considering the trade-off between workload balancing (efficiency measure) and total displacement amount...
Rebalancing the assembly lines with total squared workload and total replacement distance objectives
Girit, Utku; Azizoğlu, Meral (Informa UK Limited, 2020-01-01)
Assembly line balancing is an important and well recognised operations research problem. The current line balance may not stay optimal, even feasible, due to the disruptions in one or more workstations. In this study, after the disruption, we aim to rebalance the assembly line by considering the trade-off between workload balancing (fairness measure) and total replacement distance for the tasks assigned to the different workstations (stability measure). We try to generate all non-dominated objective functio...
