Supply Chain Management System for Construction Material Planning

This study relies on integrated inventory theory which merges with the supply chain concept and aims at the steel bar material of precast factory’s twoechelon supply chain system. In order to consider the variable demand rate, unfixed supply time, unfixed supply frequency and unfixed supply quantity, this study builds a strategic model that minimizes the total inventory cost of all participators. Based on the established model, the material’s supply plan comes into existence, which takes into consideration the time and quantity of material supply, and the starting time of the supplier’s production. It is expected that the study result can be useful reference for participators to deal with the material supply in a more efficient way.
