INTEGRATED PLANNING INFORMATION-SYSTEMS - CONTEXT, DESIGN REQUIREMENTS, AND PROSPECTS

This research contributes to the theoretical basis for appropriate des ign of computer-based, integrated planning information systems. The re search provides a framework for integrating relevant knowledge, theory , methods, and technology. Criteria for appropriate system design are clarified. The requirements for a conceptual system design are develop ed based on ''diffusion of innovation'' theory, lessons learned in the adoption and use of existing planning information systems, current in formation-processing technology (including expert system technology), and methodology for evaluation of mitigation strategies for disaster e vents. Research findings focus on the assessment of new information sy stems technology. Chief among these findings is the utility of case-ba sed reasoning for discovering and formalizing the meta rules needed by expert systems, the role of the ''diffusion of innovation'' theory in establishing design criteria, and the definition of client interests served by integrated planning information systems. The work concludes with the selection of a prototyping exercise. The prototype is develop ed in a forthcoming technical paper (Masri & Moore, 1994).
