对混合型装配线平衡问题进行了描述和数学建模,提出一种启发式求解算法,求解目标是最小化工作站数目.为进一步优化求解结果,对启发式算法求解的结果进行仿真研究,分析各工作站的工作率、等待率和阻塞率,并以此为依据调整部分作业任务的分配,允许不同品种产品的相同作业任务安排在不同的工作站中,以对求解结果进行修正,进一步均衡各工作站的作业量.该求解方法既简化了求解过程,又兼顾到了系统的瞬时特性和作业任务的不可拆分性对求解结果的影响,实例分析验证了方法的有效性.
Aiming at the problem of the balance of hybrid assembly line, this paper presents a heuristic solution algorithm to solve the problem of minimizing the number of workstations.In order to further optimize the solution, the simulation results of the heuristic algorithm are analyzed and analyzed. Of the work rate, waiting rate and blocking rate, and as part of the basis to adjust the allocation of part of the task to allow different products of the same task assignment in different workstations in order to solve the results of the amendment to further balance the work of the workstation This method not only simplifies the solving process, but also takes into account the instantaneous characteristics of the system and the inseparability of job tasks on the solution results. The example analysis verifies the effectiveness of the method.
