Abstract
This paper presents typical examples showing how production management systems have developed up to the present day in line with technological developments, market changes and the diversity ro human values. It also shows how, when systems are expanded in the light of environmental conditions, the system parameters increase, what kind of parameters have to be taken into consideration on such an occasion, and what effect they have on the characterstics of the systems. Finally, with regard to the design of production management systems, the author looks at the present state and future problems in respect of theoretical studies and of CAM as a tool for processing a large number of system parameters.
