基于网络计划技术的制造型企业时间—成本优化研究

Research on Time-Cost Optimization of Manufacturing Enterprises Based on Network Planning Technology

针对数控机床装配过程中的时间—成本优化寻求最优工期问题,提出了一种使用网络计划技术建立时间—成本优化模型来缩短工程时间和降低人工成本的方法。运用WINQSB软件中的PERT_CMP模块对该模型进行研究分析。结果表明:在机床制造型企业面对订单/需求增加时,该模型可以使企业在成本增加最小的前提下有效地缩短工期。在此基础上,以某精密机械制造厂的实际案例验证了所提出优化方法的可行性与实用性。

To seek for the optimal time limit for time-cost optimization in the assembling process of numerically controlled machine tool, this paper puts forward a method of using network planning technology to establish time-cost optimization model to shorten engineering time and reduce labor cost and uses PERT CMP module in WINQSB software to study and analyze this model. The result shows that this model can effectively shorten the time limit for project under the premise of minimum cost increase of enterprises when numerically controlled machine tool manufacturing enterprises face increased order/demand. Finally, this paper verifies the feasibility and practical applicability of the optimization method proposed with the actual case of a precision machinery manufacturing plant.
