In this paper we study an assembly line balancing problem that occurs in sheltered worker centers for the disabled, where workers with very different characteristics are present. We are interested in the situation in which complete parallel assembly lines are allowed and name the resulting problem as parallel assembly line worker assignment and balancing problem (PALWABP). This approach enables...

The General Assembly Line Balancing Problem with Setups (GALBPS) was recently defined in the literature. It adds sequence-dependent setup time considerations to the classical Simple Assembly Line Balancing Problem (SALBP) as follows: whenever a task is assigned next to another at the same workstation, a setup time must be added to compute the global workstation time, thereby providing the task ...

This research deals with a U-shaped assembly line balancing problem in which items are fixed on the conveyor. Operators execute tasks without removing from conveyor as assumed to be unsuitable for manual handling. The operators have walk beside at same speed while they tasks. If want assemble other items, may positions their normal walking speed. Therefore, cycle time of an operator should incl...

This article presents a novel alternative subgraphs assembly line balancing problem with resource selection and parallel stations. The model considers both the choice between different process alternatives of production resources for various tasks. It also allows parallelization stations in balanced line, thereby improving flexibility algorithm. objective optimization is to minimize total cost ...
