针对机电产品市场周期中配件需求预测与供应问题,应用系统工程方法,基于机电产品及其易损耗零部件的失效时间分布密度函数,发展面向机电产品市场周期的机电产品配件需求预测模型,继而提出机电产品配件生产与供应策略.以机电产品及零件的寿命分布满足正态分布函数为例,通过数值仿真,分析探讨了产品及零件失效时间分布密度函数的参数和生产批量对零件替换率和配件需求量的影响;提出了基于机电产品及零件寿命正态分布的配件生产供应方案,与常规方法对比分析表明了所提出方法的优越性.这对于有效地组织配件生产和指导配件库存管理,提高机电产品维修和售后服务水平具有重要意义.
Aiming at the demand forecast and supply of parts in the market cycle of electromechanical products, this paper develops the demand forecast model of electromechanical products for the market cycle of electromechanical products based on the distribution function of failure time of electromechanical products and its easy-to-wear parts, and then proposes The production and supply strategy of mechanical and electrical products parts.According to the normal distribution function of the life distribution of mechanical and electrical products and parts as an example, the parameters of density distribution function of product and part failure time and the replacement rate of components and parts The demand and the impact of the demand; put forward based on the mechanical and electrical products and spare parts life distribution of the normal production of parts supply program, compared with the conventional method shows the superiority of the proposed method.This is effective for organizing parts production and guidance parts inventory management, improve Electrical and mechanical product maintenance and service level is of great significance.
