考虑同质设备不同加工能力的模块化制造单元资源配置优化

Resource allocation optimization based on modular manufacturing cells considering different processing ability of homogeneous machines

针对传统制造单元易出现在制品的积压、加工效率低下的问题,提出一种模块化制造单元资源配置模型及算法.按照模块化思想进行制造单元划分,为了保证单元内部均衡,工作站内可配置若干个同类设备.考虑到同类设备之间的加工效率不同,建立以总加工成本最小及制造单元内与单元间的均衡为目标的数学模型,应用模拟植物生长算法进行求解.最后通过算例验证了模型与算法的有效性.

To solve the backlog of work in process and the low machining efficiency in traditional manufacturing cells,a resource allocation model together with its optimization algorithm is proposed. According to the ideology of modular manufacturing cells, various manufacturing cells are established. A mathematical model is established with the minimum total processing cost and equilibriums among various manufacturing cells as its goals. The plant growth simulation algorithm is applied to solve the model. Finally, a numerical example verifies the effectiveness and feasibility of the proposed model and algorithm.
