生産と物流のジャストインタイム・スケジューリング研究に関する現状

Abstract

The Just-In-Time (JIT) production has been developed as a subsystem of the "whole" Toyota production system (TPS). Currently JIT or JIT production means the TPS especially in foreign countries. It is recognized that JIT is a key concept for enterprises competing in the diversified-products market. The technologies used in JIT are comprehensive and include technologies to design, install and control a production system, which are classified into three categories : hardware, information and software technologies. The software technology consists of ones for production planning/scheduling and shop control. In this paper, the concept and importance of JIT are discussed and then JIT researches related to technology of planning/scheduling for production and logistics are reviewed.
