A Framework to the Modeling of Production/Distribution with Time Lags

摘要

Over the past decade, the traditional production model and logistics functions have evolved into a broader strategic approach to materials and distribution management known as supply chain management(SCM). However, they have some deficiencies to apply to the industrial practice, due to unrealistic assumptions. One such assumption is the requirement that processes occur instantaneously. This assumption makes it difficult to formulate the operations with significant post processing lags and transferring lags accurately. Therefore, in this paper we introduce a framework to the modeling of production/ distribution with time lags. Especially, we propose the framework for the modeling of the integrated production/ distribution with time lags that are non-integer using the concept of dynamic production function. The dynamic production function has characteristic that reflect well the situations, whether lead times are integer or non-integer. Experiments show that this model is a more reasonable than previous production/ distribution models and show its validity.
