为快速响应复杂、突变的市场,满足高效率和高柔性要求,在允许机器数量发生变化的条件下,从单元构建和单元系统布局进行集成设计与优化的高度提出了一种基于单元制造的可添/删机器的设施布局方法。首先,从物流成本和设备拆装成本的角度集成设计基于多工艺路线的单元构建与单元内设备布局,实现产品最优工艺路线、制造单元分组以及各单元内设备布局位置三者的同步输出;然后,采用连续优化的多行布局方法建立单元系统布局模型,避免设备重置带来的耦合关系,实现单元布局的集成性。利用Matlab7.0,结合实例进行验证,证明了该设备布局方法的可行性和有效性. In order to respond rapidly to complex and abrupt markets and meet the requirements of high efficiency and high flexibility, a new method of unit design and optimization based on unit building and unit system layout is proposed under the condition of allowing the number of machines to be changed. Add / delete machine facilities layout method. First of all, from the perspective of logistics costs and equipment disassembly costs, the design of unit construction and unit equipment layout based on multi-process route is designed and integrated to realize the synchronous output of the optimal product route, manufacturing unit grouping and the location of the equipment within each unit; Then, a continuous optimized multi-row layout method is used to establish the cell system layout model to avoid the coupling relationship caused by the device reset and to achieve the unit layout integration. The use of Matlab7.0, combined with examples to verify that the device layout method is feasible and effective.
