Abstract

Life Cycle Management (LCM) is a framework of concepts, techniques and procedures concerned to an environmental management of products and organizations in achieving continuous environmental improvement viewed from life cycle perspective. One tool in LCM approach is Life Cycle Assessment (LCA) which consists of a method to quantify environmental impacts associated to products or activities throughout their life cycle, begins with extraction of raw materials, proceeds through production and use, ends to waste treatment (from cradle to grave). This research deals with analysis of LCA for products of Fluorescent Lamp of 20 Watt. The research question exposed is how to evaluate the best alternative to improve environmental performance among many strategies designed on LCA results. Due to in the real system, environmental consideration is not the only one criteria used for decision making, this research proposes to takes into account for multi criteria evaluation in selection of the best strategy such as criteria of investment cost, corporate image etc, to do so the method of AHP (Analytical Hierarchy Process) is proposed to apply. In order to evaluate the environmental impact associated the process throughout the life cycle the product, existing database built in SimaPro-5 software. This research concludes that the strategy of “product take back” principle is the best solution in order to achieve the optimal environmental performance.

Abstract

This paper proposes a development of Fuzzy Goal Programming model with imprecise information goal for optimizing the regional water quality management. Imprecision is associated with fuzziness which is non-statistical in nature and refers to the absence of sharp boundary in the information. Imprecise standards in environmental management objective could be represented by fuzziness functions. The objectives of management to be achieved in this model are categorized as: (i) Environmental objectives i.e. to maintain an ambient water quality in two parameters and standards, BOD(Biochemical Oxygen Demand) and DO (Dissolved Oxygen) closed to desired stream standard goal and to achieve an improvement sanitation program target;(ii) Economic objective i.e. to minimize the total cost of removing residual by an alternatives waste of treatment systems. The model of "Streeter Phelps" is adopted to represent the ecological relationship between organic pollutant loading and fluctuated water quality. Then fuzzy goal programming is developed as one of Multi Criteria Decision Making (MCDM) approach to "optimize" the objectives of decisions, in order to calculate how many pollutant should be removed at each system. The solution of the model provides a way of trade off analysis between attainment of objectives and useful imprecise information to the decision maker of environmental planning
