The domain considered, comprises proposed research work applied to investment in agro-based industrial sector using Expert Systems techniques, CASE technology, Zachman s Framework, financial analysis, risk analysis, and qualitative analyses. The knowledge-based system, called AIES, enables users to determine the proper feasibility assessment for installation of agro-industries, which encompasses relationships among the many factors of the decision-making process across the domains of economic, financial, legal, technical, marketing, and environmental feasibilities. The AIES consolidates 57 decision-making factors into economical, technical, and general feasibilities in the proposed Expert System s Model, along with weight assignments to these parameters. Certainty Factors addition formula was adopted to evaluate the ES model. The AIES elicits, extracts, and consolidates the knowledge of experts of a variety of disciplines, like, Managerial and Agricultural Economics, Industrial Management, Statistics, and Information Technology, heretofore unfamiliar with one another s fields.
