Recently, there has been a rapid development of the technical innovation in a H/W architecture, allowing EWS (Engineering Work Station) to achieve such a performance as to be comparable to the performance of the main frame computer. Thus, since about 1992, there has been a marked tendency to extend the application of EWS which has been limited to academic or engineering use, to computer systems for business use. It has become a popular way to construct a computer system on the basis of the Down-sizing concept.Now, the author will explain the attitude of Daido Steel Company to such a tendency of application of Down-sizing system to business use and some examples thereof.In the authors view, the merits of Down-sizing system are as follows:(1) We can develop a system under the OPEN environment using highly cost effective products of H/W and S/W freely from the venders restriction:(2) We can expand the range of the computer systems application through the user-friendly operation using GUI and Object oriented programming: and(3) We can reduce the total cost of computer systems.In principle, we will use Down-sizing approach to our new system developments and adopt 4 types of basic style; a planning assistant system, a support system of information reference, a support system of an accumulation of printing outputs, and a production control system at a small plant.
