投入产出生产函数在生产计划管理中的应用

Application of Input output Production Function to Make Production Plan

探讨了如何应用投入产出生产函数为订货生产类型的企业制订企业生产计划大纲和产品进度计划问题．将企业的整个生产过程划分为多个生产节点，根据生产节点划分的规则，不同品种的产品生产所需经过的路径可由产品依次经过的生产节点来描述．生产节点间的投入产出关系，以及生产过程中普遍存在着的动态随机性，则借助于动态随机生产函数来反映，从而使计划人员估计不确定性对完成项目时间的影响．在此基础上，同时考虑到订货生产类型企业的特点，在制订企业的生产计划大纲时，应用静态生产函数，制订企业的产品进度计划时。

The application of input output production function to make production plan outline and product scheduling of make to order enterprises are studied. The manufacturing system is divided into production nodes or process centers. According to the rule of dividing the manufacturing system, the route of each varied productions can be described by the production nodes they pass. The input output relations among production nodes and the dynamic and stochastic factors existing generally during production processes can be reflected by the model of dynamic & stochastic production function, in order that planners can estimate the stochactic factors which influence the manufacturing time. On the basis mentioned above of , considering the specificity of make to order enterprises, the production plan outline is made by the model of static production function, and the product scheduling is made by the model of dynamic & stochastic production function.
