A decision maker method, TOPSIS is subsequently applied to determine the best solution from Pareto front.
Decision makers need methods to help them identify the optimal allocation of limited resources to meet conservation goals, and decision analysis is uniquely suited to assist with the development of such methods.
Caution is needed when CVM is the sole method used to advise policy decision makers, with mixed methods using qualitative interviews to capture caregiver motives for refusing to answer the WTP question probably being preferable [54].
In fact, if they are considered as the desirable goals of the decision makers, the employed method should be able to have a general evaluation based on the results of Table 4 and the importance of each of the economic, social and environmental dimensions.
The subjective methods determine weights solely according to the preference or judgments of decision makers, and then some mathematic methods such as the eigenvector method, weighted least square method, Delphi method, and mathematical programming models are applied to calculate the overall evaluation of each decision maker.
Many health care decision makers have been seeking methods of more efficiently and effectively treating chronic disease; frequently, these methods include the development and implementation of disease management programs [ 1].
Because our goal is to generate a tool that is used by and useful to decision makers we are exploring methods to better understand how decision makers understand and respond to the manner in which information is presented.
Due to the fact that most researchers in the literature employed three decision makers to test their method, furthermore, in this research we used three experts, D1, D2, and D3, to form a committee to act as decision makers.
To apply this method, decision makers need to change their tolerance value at each iterative step and this might cause a delay in arriving at a satisfactory solution, especially for large problems.
While these results can be useful as a scientific basis of sediment management and selecting the soil erosion control methods for decision makers of natural resources they also show that it may not always be possible to identify sediment sources with great precision.
