ABSTRAK

 

Keputusan terakhir yang dicari dalam menyelesaikan masalah berbilang kriteria ialah satu pangkat kedudukan unit yang dianalisis berdasarkan prestasi keseluruhan unit-unit tersebut. Satu cara untuk mendapatkan prestasi keseluruhan setiap unit adalah dengan menggabungkan prestasi dan wajaran kriteria masing-masing melalui pelbagai kaedah pengagregatan. Kajian tertumpu kepada penerapan tiga kaedah asas pangkat dalam menilai kepentingan kriteria yang melibatkan satu panel penilai dengan kewibawaan berbeza. Hanya dua pendekatan pengagregatan berasaskan kaedah pemurataan tertib berpemberat sesuai diutarakan agar hasil akhir boleh dicapai. Setiap pendekatan pengagregatan yang dicadangkan diringi dengan contoh pengiraan.

 

Kata kunci: Kewibawaan; masalah berbilang kriteria; pangkat; pengagregatan; wajaran

 

 

ABSTRACT

 

The final goal in solving multi-criteria problems is a ranking of the analyzed units based on their overall performance. One way to obtain the overall performance of each unit is by combining its performances and weights of criteria through various aggregation methods. This research focused on the application of three rank-based methods to evaluate the relative importance of criteria which involved one panel evaluators with different credibilitity. There are only two suitable aggregation approaches based on ordered weighted average method are proposed in order to achieve the final result. Every approach proposed is followed by a numerical example.

 

Keywords: Aggregation; credibility; multi-criteria problem; rank; weights
