动态随机生产函数模型中库存量的确定

THE CONFIRMATION OF STOCK IN THE DYNAMIC AND STOCHASTIC PRODUCTION FUNCTION MODEL

生产制造系统在某种程度上具有不确定性,库存量是影响生产系统的诸多随机变量之一,它随着市场需求、库存成本、企业生产能力等的改变而改变.本文以原有的动态随机生产函数模型为基础,通过在模型中引入库存变化这一随机因素,对该理论模型进行了改进与扩充,使其更加符合生产系统的实际.

The production and manufacturing system experiences some uncertainties to some extent. Stock is one of the many random variables that affects the production system. It changes with market demand, stock cost and production capability of the enterprise etc. On the basis of the primary dynamic and stochastic production function model, the paper improves and extends the theoretical model to make it more consistent with the actual practice by introducing the stock variable into the model.
