Technique | Advantages | Disadvantages | Areas of application |
---|---|---|---|
Analytic Hierarchy Process (AHP) | Easy to use; scalable; the hierarchy structure can be easily adjusted to many sized problems; not data intensive; the use of pairwise comparisons allows more accurate information to be obtained from decision makers. Check inconsistency in the judgements | Problems due to interdependence between criteria and alternatives; can lead to inconsistencies between judgement and ranking criteria; rank reversal. | Performance problems, resource management, corporate policy and strategy, public policy, political strategy and planning. |
Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) | A simple process; easy to use and programme; the number of steps remains the same regardless of the number of criteria; it returns stable results if input data are oscillating. More robust involving all stakeholders and interrelations between alternatives and objectives. | The use of Euclidean distances does not take into account the correlation of criteria; difficult to weight and to maintain consistency between judgements. Rank reversal. | Supply chain management and logistics, engineering, manufacturing systems, business and marketing, environment, human resources and water resources management. |
Simple Additive Weighting (SAW) | Ability to compensate between criteria; intuitive for decision makers; simple calculation. | Estimates do not always reflect the real situations; the results obtained may not be logical. | Water management, business and financial management. |
ELimination Et Choix Traduisant la REalité (ELECTRE) | Accounts for uncertainty and vagueness. | Its process and results may be complex to explain in layman’s terms; outranking can lead to the strengths and weaknesses of the alternatives not being directly identified. Rank reversal. | Energy, economics, environmental, water management and transportation problem. |
Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) | Easy to use; does not require assumption that criteria are proportionate. | Provides no procedure for obtaining weights for the criteria. Rank reversal. | Environmental hydrology, water management, business and finance, chemistry, logistics and transportation, manufacturing and assembly, energy, agriculture. |
Measuring attractiveness through a categorical-based evaluation technique[(MACBETH) | Uses a value tree to structure a problem; the use of pairwise comparisons allows more accurate information to be obtained from decision makers. Avoids inconsistency in the judgements. Uses two reference levels for more objective judgements. | Its application is time-consuming. | Airport management, credit scoring, and strategic town planning, maintenance, energy, water management. |
VIekriterijumsko KOmpromisno Rangiranje (VIKOR) | Able to establish the stability of decision performance; aggregate function is closest to the best solutions; the criteria selected may not allow homogeneous aggregation | Searching for the compromise ranking order; use of complex linear normalisation process; needs initial weights. | Renewable energy, service quality, earthquake sustainable reconstruction, material selection, land-use strategy |
