Pemilihan sistem pelupusan sisa pepejal perbandaran menggunakan model dwikabur konflik

This research focuses on the application of a new fuzzy model for selecting municipal solid waste (MSW) disposal systems which recently has been big burden, particularly in central Peninsular Malaysia. The state of Selangor and Kuala Lumpur Federal Territoring (KLFT) for instance, recorded the highest MSW generation which estimated more than 2.32 million tonnes per year in 2005. Generally, the process to identify the most suitable disposal system involves various criteria and the options. It also involves the multi-criteria consideration from multiple stakeholders in decision process. In view of this problem, the conflicting bifuzzy multi-criteria model was proposed in an analytic hierarchy process (AHP) method using linguistic hedges concepts (i.e., dilation and concentration). This approach was adopted by using the new set theory, namely ‘conflicting bifuzzy set’. A case study in the state of Selangor and KLFT was utilised to demonstrate the applicable of the proposed model. Based on the calculations, the model offers a comprehensive evaluation in order to have on equilibrium characteristics in every single evaluation processes. Besides that, it also deals efficiently with the uncertainty in initial information through fully linguistic approach thus can assist the decision makers to make a better decision in an effective manner
