화일배경 문제와 컴퓨터 위치선정문제를 동시에 고려한 분산정보시스팀의 모형화

Abstract

We have undertaken to develop an efficient solution methodology to adress distributed information system configuration problems through mathematical programming. We have simultaneously considered file allocation and computer location assignment problems which are two aspects of the design tighly coupled in a distributed computer system. A model for solving the problem is shown to be a class of nonlinearinteger programming problems and procedures are developed for computing its lower bound. A heuristic algorithm is also developed and some results are obtained. Numerical results yield practical low cost solutions with substantial savings in computer processing time.
