Abstract
With the rapid development of economic globalization and information technology, the competition between enterprises is more and more stiff. Under such a social background, if an enterprise wants to survive, it is necessary to improve its own competitiveness. However, most manufacturing is reduced by improving facilities layout. By investigation and analysis, Yimeng packing factory in order to meet the various needs of the consumers, the original assembly line production mode to the direction of mass customization development, making the enterprise facilities units increased, the relationship becomes more and more complex, therefore, a good facility layout design is very important. From the current situation of Yimeng packing factory facilities layout, i found that there are some problems, planning staff did not consider all factors and not fully take into account the subsequent development of the enterprise, resulting in a large number of internal material flow, increase the material handling distance and logistics; In the production site, there are a number of production equipments sharing cache areas, causing a mess of semi-finished products piled up, regional division is unreasonable. In view of the above problems, the solution method of the combination of the system layout design and the single parent genetic algorithm is proposed. Firstly, application system design and layout (SLP) method, factory logistics, non logistics factors were analyzed, and considering the actual conditions and correction factors for the restrictions on three feasible facility layout initial scheme. Secondly, using the analytic hierarchy process, the initial scheme is evaluated. Finally, the initial optimization scheme of SLP substitution to the partheno genetic algorithm (PGA) algorithm, establishes the mathematical model, the logistics cost as optimization objective function of the facility layout of workshop, workshop facility layout of a given constraint conditions,application of MATLAB software for simulation and optimization. By Yimeng packing factory before and after optimization layout scheme of analysis result, optimized layout scheme than the original scheme of material handling quantity reduced 11859.48 kg m , material handling costs reduce 14757.22yuan. By combining the SLP method and PGA method, re arrangement work location, material handling distance and time is shortened, reducing transport costs,

摘 要
随着经济的全球化和信息技术的迅猛发展，企业间的竞争变得越来越激 烈。在这样的社会大背景下，一个企业若想生存下来，就必须提高自身竞争 力。然而，大多数制造业都通过改善设施布置来降低成本。经调研分析，益盟 包装厂为了满足消费者需求的多样性，将原来的流水线生产模式向大规模定制 方向发展，使得企业的设施单元增多、相互关系变的越来越复杂，因此，一个 良好的设施布置设计是非常重要的。 从益盟包装厂设施布置现状入手，发现存在一定问题，规划人员没有考虑 所有因素以及未充分考虑到企业后续的发展，造成企业内部大量存在物料迂回 流动，增加物料的搬运距离和物流成本；在生产现场，存在多个生产设备共用 缓存区的情况，造成半成品堆放混乱，区域划分不合理。针对上述问题，提出 了系统布置设计和单亲遗传算法相结合的解决方法。首先，应用系统布置设计 （SLP ）方法，对工厂内部的物流、非物流因素进行分析，并考虑实际条件和 修正因素的限制，得到 3 个可行的设施布置初始方案。其次，应用层次分析 法，对初始方案进行评价择优。最后，将 SLP 得到的初始优选方案代入到单亲 遗传算法（PGA）算法中，建立数学模型，将物流费用作为车间设施布置的优 化目标函数，给定车间设施布局的约束条件，应用 MATLAB 软件进行仿真优 化。通过益盟包装厂优化前后布置方案的结果分析得出，优化后布置方案比原 方案的物料搬运量减少了 11859.48 kg m ，物料搬运成本减少 14757.22 元。通 过 SLP 方法和 PGA 结合的方法，重新布置作业位置，缩短物料的搬运距离和 时间，降低搬运费用，提高企业的物流效率和空间利用率，使设施布置更加合 理。 关键词：系统布置设计；层次分析法；单亲遗传算法
