The bin packing problem can be best described in 'transportation' terms: given a set of boxes of different sizes, how should one pack them all into containers of a given size, in order to use as few containers as possible? The task of balancing of (robotized) assembly lines is of considerable industrial importance. It consists of assigning operations from a given set to workstations in a produc...

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 ...

Abstract Nowadays, rapid product iterations result in large quantities of end-of-life products. To meet the fast-growing demand for remanufacturing engineering, companies have quickened standardization and industrialization waste dissembling. Two-sided disassembly lines can effectively disassemble large-sized products on both sides lines, parallel multiple simultaneously with fewer workstations...
