An Approach to Development of Decision Support Systems for a Public Sector Administration
本文提出了一种结合软系统方法论（SSM）的决策支持系统开发方法，用于处理公共部门复杂决策中的信息不一致、不完整和不确定问题，并阐明了SSM在系统开发生命周期中的角色。
The decision making process in complex domains involves inconsistent, incomplete and uncertain information and a lack of established models or theories. These characteristics influence the nature of approach to be used in the development of any decision aids to support the process. This paper presents an approach adopted in the development of a DSS to support complex decision making in a Public Sector body. The approach incorporates the use of Soft System Methodology (SSM). The role of SSM in Information Systems in general and in the development of DSS in particular is not well understood. This paper attempts to enhance this understanding by presenting the role of SSM in the development life cycle. SSM was found to be useful especially at the initial stage of DSS development, namely in understanding the problem area, as well as in identifying models and information to be used as inputs to the DSS design.
