摘　　要：针对目前装配生产线普遍存在的生产效率低下、资源利用率不高的问题.本文以大型装配生产线为研究对象,对其进行资源优化配置.首先,构建有效的装配线Petri网模型,并配置保证Petri网正常运行的最少资源.其次,基于线性规划提出一种用于装配生产线优化的通用启发式算法,对装配生产线进行资源优化配置.在不超过预算的基础上,使生产线的生产效率最大化.最后,以某公司的汽车液力变矩器装配生产线为例,采用本文提出算法对该生产线进行资源优化配置,并通过仿真验证了算法的有效性.In view of the current low production efficiency and resource utilization rate of the assembly line,this paper takes the large assembly line as the research object and optimizes the resource allocation problem.First,we construct a Petri net model to describe an assembly line effectively and deploy the minimum resources to ensure the normal operation of the network.In addition,in order to maximize the production efficiency of the production lines under a limited budget,we develop a heuristic algorithm based on linear programming suitable for resource optimization of assembly lines.Finally,taking the hydraulic torque converter assembly line of a car manufacturing system as an example,we use the proposed algorithm to optimize the resource allocation of the assembly line.Thereby,according to simulate the optimization results and validate the correctness of the proposed algorithm.
