Line balancing is an effective tool to improve the throughput of assembly line while reducing nonvalue-added activities, cycle time. LB is the problem of assigning operation to workstation along an assembly line, in such a way that assignment is optimal in some sense. This paper mainly focuses on improving overall efficiency of single model assembly line by reducing the non value added activiti...

This paper wants to present an integrated approach to Line Balancing and Risk Assessment and a Software Tool named ErgoAnalysis that makes it easy to control the whole production process and produces a Risk Index for the actual work tasks in an Assembly Line. Assembly Line Balancing, or simply Line Balancing, is the problem of assigning operations to workstations along an assembly line, in such...

Assembly line balancing (ALB) and sequencing is an active area of optimization research in operations management. The concept of an assembly line (AL) came to the fact when the finished product is inclined to the perception of product modularity. Usually interchangeable parts of the final product are assembled in sequence using best possibly designed logistics in an AL. The initial stage of con...

An interesting empirical result in the assembly line literature states that slightly unbalanced assembly lines (in the format of a bowl with central stations less loaded than the external ones) present higher throughputs than perfectly balanced ones. This effect is known as the bowl phenomenon. In this study, we analyze the presence of this phenomenon in assembly lines with integer task times. ...

Mixed-model assembly line (MMAL) is a type of production line where a variety of product models similar to product characteristics are assembled. Line balancing and model sequencing problems are important for an efficient use of such lines. This paper presents integer programming formulation and a solution for a loading and assembly plan selection problem in a mixed-model assembly system. The p...

Time and space assembly line balancing considers realistic multiobjective versions of the classical assembly line balancing industrial problems involving the joint optimization of conflicting criteria such as the cycle time, the number of stations, and/or the area of these stations. In addition to their multi-criteria nature, the different problems included in this field inherit the precedence ...

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...

This paper presents a real-world industrial application of the multi-product and multi-objective scheduling and assembly line balancing problem, for a company involved in the production of four models of a product. Two objectives are considered: production rate maximization and minimization the dispersion of worker tasks on each one of the different models. An integrated approach for the schedu...

Assembly line balancing problem (ALBP) is a decision problem arising when designing or redesigning an assembly line and it consists in finding the optimal assignment of tasks among the workstations corresponding to some objectives. This paper deals with the single-model ALBP with the aim of minimizing the cycle time and maximizing the workload smoothness among the workstations. In order to solv...
