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 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.
