一、引言 管理信息系统的开发是一个系统工程,首先要涉及的是计算机系统,因为计算机系统是管理信息系统的物质基础,能否选择符合要求的计算机系统,是成功地开发管理信息系统的关键之一。要统筹全局,合理选择计算机的型号,以保证管理信息系统各项功能的实现;如果忽视了计算机系统的选型,盲目购进计算机系统,当需求有所变化,必须改动和扩充管理信息系统时,常常遇到困难,甚至竟陷入“削足适履”的难堪局面。 为合理选择计算机系统,要对计算机系统选型方案加以评价。第一步,是粗选机型,用专家会议法
I. INTRODUCTION The development of management information system is a systematic project. The first thing to be concerned is the computer system. Because computer system is the material basis of management information system, whether to choose the computer system that meets the requirements is the key to the successful development of management information system one. To overall planning and reasonable choice of computer models in order to ensure that the management information system to achieve the various functions; ignore the selection of computer systems, blind access to computer systems, when the demand changes, we must change and expand the management information system , Often encounter difficulties, or even actually caught in the “cut enough fit” embarrassment. In order to select the computer system reasonably, we must evaluate the computer system selection plan. The first step is rougher models, with expert conference law
