Abstract
In design of machinary, computers are very useful and many jobs are aided by computer system and treated more efficient than before. Under recent sever economical environment, cost-benefit becomes important and many computer systems are developed for the sake to do jobs efficiently. Computer networks is the result of the ARPA project and now, this becomes important infrastructure. The success of the design system using computer networks becomes the key-point of the success of the bussiness and design of the product. In this fundamental examination, the authors have developed the design system for the design optimization under computer networks and tried to apply for the simple numerical examples.
