PERFORMANCE MODEL OF DATABASE RELATIONSHIP TO DESIGN AND MANUFACTURING
Recent trends of economization in the development and applications of computer software systems have become an important consideration for the design of modern computer systems. This has increased the efforts towards the study, evaluation and testing of the computer software. The model of information system presented here, is comprised of three subsystems viz,; CAD, Database and CAM namely as A, B and C respectively. Computer-Aided-Design (CAD) is a major element of a computer-integrated manufacturing system. CAD involves any type of design activity that makes use of the computer to develop, analyze, or modify an engineering design. First of all interactive graphics is entered into CAD then it interacts with database and at the last it comes under Computer-Aided-Manufacturing (CAM), which is another major part of manufacturing system. In the performance model of database relationship to design and manufacturing considered in this paper has all failure rates to be following exponential distribution and repair times to be following general time distributions. By the inclusion of supplementary variable and Laplace Transforms technique, all state probabilities, graphs of reliability v/s time, expected profit v/s time and MTTF v/s all types of failures have been sketched in the end so as to forecast the operable behavior of such performance model.
