Production Planning and Control System or FA
Wataru Yuzawa
The FA, which has been developed up from the bottom on the basis of the rapid progress of hardware technology, and the production planning and control system, which has been developed down from the top aiming at integration, link each other at shopfloor control. The production planning and control system has many problems in support of FA partly because of a little delayed development of software technology. This paper describes the role of production planning and control for FA from the viewpoints of its trends, problems and needs, and in addition, the concept and technology of the systems which has been developed and introduced by Fuji Electric.
Methodology for Factory Automation System Design
Makoto Furuya
The FA system consists of many subsystems, which have their own functions to execute. In order to design the system in which these subsystems link organically to exercise their functions completely, it is necessary to establish methodology for system design so that all members should design with the same design philosophy and design procedure. This paper describes the methodology for factory automation system design, which is established by Fuji Electric with its many years' experience and know-how, from the viewpoints of methodology for system design and that for project management, and also a procedure for system design to make it possible to design high quality systems efficiently in short time.
General-Purpose Material-Flow Control System, ΦNET
