ABSTRAK
Kajian ini memfokuskan penggunaan model kabur baru untuk pemilihan sistem pelupusan sisa pepejal perbandaran (SPP) yang dewasa ini dilihat semakin menghambat terutamanya negeri-negeri di bahagian tengah Semenanjung Malaysia. Rekod menunjukkan negeri Selangor dan Wilayah Persekutuan Kuala Lumpur (WPKL) mencatatkan penghasilan SPP tertinggi melebihi 2.32 juta tan setahun pada tahun 2005. Lazimnya, proses untuk menentukan sistem pelupusan yang sesuai melibatkan pengenalpastian matlamat dan kriteria berdasarkan pilihan yang ada. Ia juga bersifat pertimbangan multi-kriteria yang melibatkan banyak pihak berkepentingan dalam membuat keputusan. Berdasarkan permasalahan tersebut, model multi-kriteria dwikabur konflik diusulkan menggunakan konsep penegasan linguistik (i.i., dilasi dan konsentrasi) dalam proses hierarki analitik (AHP). Model ini diubahsuai menggunakan teori set baru yang diberi nama ‘set dwikabur konflik’. Kajian kes di negeri Selangor dan WPKL dimanfaatkan sepenuhnya untuk menunjukkan kesesuaian model yang diusulkan. Berdasarkan pengiraan yang ditunjukkan, model yang diusulkan dapat menilai kesemua kriteria secara lebih menyeluruh disebabkan sifat ‘timbal balas’ yang dimilikinya. Di samping itu, ia mampu menangani masalah yang bersifat berketaktentuan secara berkesan disebabkan pembuat keputusan boleh menilai secara linguistik sepenuhnya sekaligus memudahkan mereka membuat keputusan dengan lebih cekap dan berkesan.
Kata kunci: Model dwikabur konflik; pembuat keputusan multi-kriteria; sisa pepejal perbandaran
ABSTRACT
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.
Keywords: Conflicting bifuzzy model; multi-criteria decision making; municipal solid waste
