A. (Riham A.)Flexible manpower lines (FMLs) are a form of flow process line in which operators are allocated 'walk cycles', i.e. a repetitive sequence in which to load and unload machine tools. The effective design of such lines is normally achieved with the expectation that operators without full walk cycles, i.e. those that do not require a full Takt time to accomplish, can complete their walk cycles at an adjoining FML. However, an alternative FML design strategy is possible in cases where no adjoining FML exists or it is not possible for operators to move between work areas. This strategy involves determining the minimum Takt time and the associated operator walk cycles at which the FML can operate under a fixed number of operators. To solve this type of problem, a genetic algorithm that make use of a novel crossover operator has been developed that can design FMLs. The genetic algorithm is capable of generating, for a specific Takt time and fixed number of operators, FMLs with high-quality, near-optimal operator walk cycles. Solutions for the fixed manpower case were then identified by performing multiple genetic algorithm runs to find the best walk cycles at various Takt times.Item Metadata only Designing multi-component flexible manpower lines.(JSAE, 2005) Stockton, David; Khalil, R. A. (Riham A.); Newman, S. T.; Ardon-Finch, J. P. (Jason P.)The use of multi-component flexible manpower lines (MCFMLs) is seen as one method of enabling component suppliers to deliver the cost reductions and increased flexibility of service levels expected by automotive manufacturers. This paper describes research undertaken to develop an advanced genetic algorithm optimization/simulation toolkit that is capable of automatically generating optimized MCFML designs. In order to deal effectively with the high levels of product and process variability that exist within MCFMLs research is reported that is aimed at developing methods for measuring the effects of variability on individual workstations along such lines.
