JIT system has been introduced from 1970`s through 1980`s in foreign companies. There was more emphasis on JIT strengths than JIT weaknesses during those periods. But at the end of 1980`s through the beginning of 1990`s, many foreign companies also hold a JIT merits in common. After that, those companies are interested in the merits of western production techniques (espically CIM, MRPⅡ and OPT). And then, they discussed JIT system weaknesses. Here this article classifies two types of limits(problems) about JIT weaknesses. The one is managerial problems caused in the introduction of JIT system. The other is technical problems that it doesn`t own the merits of western production techniques. According to Ptak, the future success of manufacturing can not depend on only one of these concepts(MRP, MRPⅡ, JIT, OPT or CIM) ; a company must draw from the entire gamut to extract what makes sence for that particular company.
