不确定需求下的设备动态布局方法
Dynamic Facility Layout Method under Uncertain Product Demands
摘要
Abstract
The dynamic facility layout method combined with fuzzy set theory and improved genet-ic algorithm was brought out on the basis of considering the influences of uncertain product demands, aiming at the deficiency of the present dynamic facility layout method.The characteristics of product demand uncertainty change over time were analyzed,and the uncertain demands were described by the triangular fuzzy numbers.The dynamic layout was transformed into several static layouts through an-alyzed facility relocation process between each period so as to establish a dynamic facility layout model under uncertain demands based on flexible bays structure.An improved genetic algorithm was pro-posed by combined triangular fuzzy number operation and adaptive local search with genetic algo-rithm,and then solved dynamic facility layout problems with uncertain product demands and unequal area constraints;the target of the problem was minimum the total cost of material handling and facili-ty relocation.At last,the examples were illustrated to verify the practicability and effectiveness of the given method.关键词
