造船企业中管子生产线柔性资源分配研究

为解决造船企业管子生产线各工序间资源负荷比例的不稳定性所导致的在制品量多、加工周期长的问题,基于船舶管子制造的特征现状,以加工周期最短为目标,描述了一种多生产线柔性资源分配问题.建立柔性资源分配变量矩阵并提出工序当量生产能力的计算公式,采用离散事件仿真平台Arena12.0提出该问题的求解方法及步骤.最后以国内某造船厂碳钢管子和不锈钢管子生产线为工程背景,应用Arena12.0进行了仿真实例分析,验证了该方法的有效性和实用性.

Study of Flexible Resource Allocation in Tube Production Lines for Shipbuilding Enterprises

To solve the problem of high volume of work in process and long processing cycle caused by the instability of resources＇ load pro- portion aroused from the change of plan in the tube multiple production lines for shipbuilding enterprises, a study on flexible resource alloca- tion with the target of minimum processing cycle is proposed. First, the problem of flexible resource allocation in multiple production lines is described by establishing the ability efficiency matrix, resource allocation variable matrix and the formula of production capacity of each process. Second, a solution based on Arenal 2.0 of discrete event simulation is studied. At last, the validity and practicability of the solution is verified through a simulation example.
