EcoSys{trademark}: Supporting Green Design through an extensible life cycle analysis approach

EcoSys is an environmental decision support tool to assist in the design of green products and process. EcoSys consist of an information and expert system that contains input from experts in products, processes and the environment as well as a flexible, goal driven, rule based decision model that can accommodate many environmental management perspectives. This includes allowing specific users to specify weighting factors for the impact decision model. This tool is extensible in that it can be utilized within the boundaries of a company and migrated to include suppliers and customers until full life cycles are assessed. We discussed the details and use of the environmental models available for the experts. We also showed how interviews with manufacturing experts led to the design of a goal-driven rule based reasoning system to support the problem solving. Finally, we offered a number of examples that detailed the types of analysis possible with EcoSys. Our ongoing work is to increase the precision of the environmental attributes database and to extend the product-process database to support a wider set of product analyses. Based on user feedback, we are also continuing to improve the X-Window user interface
