Application of Micro Input-Output Theory to Enterprises' Logistics System

摘要: 针对工厂企业物流系统的结构形式和特点,探讨了如何将描述企业投入产出关系的动态随机生产函数模型应用于制定企业的物流计划.动态随机生产函数模型可以反映各生产节点物流的种类、数量、空间和时间关系,以及随机因素的影响.通过在模型中引入周期生产能力的变化,进一步改进动态随机模型.研究表明,动态随机生产函数模型能够有效地制定企业的物流计划.Abstract: Based on the structure and the character of enterprises' logistics system, application of dynamic and stochastic production function which describes the input-output relation of an enterprise to logistics scheduling was discussed. The type, quantity, time and space of a flow of produce nodes can be expressed by the dynamic and stochastics production function. By introducing periodic production capacity into the model, the dynamic and stochastic model was improved. The results indicated that better logistics schedule can be obtained with the improved dynamic and stochastics production function.
