Science and technology association is producing huge amount of information through the academic activities related in industrial technology between the members and becoming major provider of industrial technology information. But the infrastructure in its individual institute of institution is very poor, which makes systematic management and service unavailable. So, KISTI developed the management and logistics system collecting and processing various technical information produced by institutes and managing as well as distributing through the web. We studied cases matched with requirements of institution and opted for the modeling, using web based application and information retrieval system. Finally, the members of the institution as well as unregistered users can access to the technical reports database easily and quickly. We are planning to extend the range of target institutes and make a progress the system to high functional level.

In existing models in optimization, the crisp data improve has been used in the objective or constraints to derive the optimal solution, Besides, the subjective environments are eliminated because the complex and uncertain circumstances were regarded as Probable ambiguity, In other words those optimal solutions in the existing models could be the complete satisfactory solutions to the objective functions in the Process of application for industrial engineering methods to minimize risks of decision-making. As a result of those, decision-makers in location Problems couldn't face appropriately with the variation of demand as well as other variables and couldn't Provide the chance of wide selection because of the insufficient information. So under the circumstance. it has been to develop the model for the location and size decision problems of logistics facility in the use of the fuzzy theory in the intention of making the most reasonable decision in the Point of subjective view under ambiguous circumstances, in the foundation of the existing decision-making problems which must satisfy the constraints to optimize the objective function in strictly given conditions in this study. Introducing the Process used in this study after the establishment of a general mixed integer Programming(MIP) model based upon the result of existing studies to decide the location and size simultaneously, a fuzzy mixed integer Programming(FMIP) model has been developed in the use of fuzzy theory. And the general linear Programming software, LINDO 6.01 has been used to simulate, to evaluate the developed model with the examples and to judge of the appropriateness and adaptability of the model(FMIP) in the real world.
