The term decision matrix is used to describe a multiple-criteria decision analysis (MCDA) problem. An MCDA problem, where there are M alternative options and each needs to be assessed on N criteria, can be described by the decision matrix which has N rows and M columns, or M × N elements, as shown in the following table.
The decision-matrix method, also Pugh method or Pugh concept selection, invented by Stuart Pugh, [1] is a qualitative technique used to rank the multi-dimensional options of an option set. It is frequently used in engineering for making design decisions but can also be used to rank investment options, vendor options, product options or any ...
For a simple numerical example suppose that a decision problem of this type is defined on three alternative choices A 1, A 2, A 3 each described in terms of four criteria C 1, C 2, C 3 and C 4. Furthermore, let the numerical data for this problem be as in the following decision matrix:
In this example a company should prefer product B's risk and payoffs under realistic risk preference coefficients. Multiple-criteria decision-making (MCDM) or multiple-criteria decision analysis (MCDA) is a sub-discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making (both in daily life and in settings such as business, government and medicine).
Teachers and users of the AHP know that the best way to understand it is to work through an example. The example below shows how a broad range of considerations can be managed through the use of the analytic hierarchy process. The decision at hand requires a reasonably complex hierarchy to describe.
Decision trees, influence diagrams, utility functions, and other decision analysis tools and methods are taught to undergraduate students in schools of business, health economics, and public health, and are examples of operations research or management science methods. These tools are also used to predict decisions of householders in normal and ...
For example, there is an effective decision procedure for the elementary integration of any ... Halava, Vesa (1997). Decidable and undecidable problems in matrix ...
An assessment of an option can be more reliably and realistically represented by a belief decision matrix than by a conventional decision matrix. It accepts data of different formats with various types of uncertainties as inputs, such as single numerical values, probability distributions, and subjective judgments with belief degrees.
