Abstract

This paper aims to introduce the theoretical bases and technical applications of software models to all users and decision makers in order to leverage technical awareness for managerial staff, and certain of its effectively in rational decision and fields of use. The researcher selected (Excel) software because it contains technical tools and easiness in use. The research depends on comparison between three major types of selected models they are; what-If analysis, goal seeking, and Solver, which are the most important models in DSS. The results of this research are represented by varying of effectiveness of analytical techniques, the solver achieved highest level of effectiveness, because its capability of dealing with multiple decision variables, in addition to treat set of constraints related to the problem. In spite of the benefits of this analysis technique, the user cannot cession of the other analysis technique because its benefits in other fields..
