This investigation proposes the bases of a decision support model based on compensatory fuzzy logic, in order to assist the selection of technological combination to integrate information systems in a supply chain.In order to do so, theoretical definitions are given about main supply chain characteristics, about the use an role of information technology in the integration of these supply chains, and also regarding information systems integration and enterprise application integration technologies. Later a model proposal is explained, together with a general idea of the employed decision making approach, that include multi-criteria and compensatory fuzzy logic elements.
