Decisor: A Software Tool to Drive Complex Decisions with Analytic Hierarchy Process

Abstract

Addressing consistent and reliable decision-making are crucial activities when choosing seemingly related alternatives for a set of criteria. Models and methods for aiding decisions such as analytic hierarchy process (AHP) were developed to handle quantified assessments of quality attributes, usually intangible and numerically hard to cope. We introduce the Decisor software tool to assist the use of AHP to drive complex decision modeling. We present a study of related tools describing advantages and drawbacks. The tool is user friendly, with intuitive data entry fields. Users may input alternatives and criteria, assigning weights from different judgment scales. Decisor’s main characteristic is its simple interface where the tool computes priority vectors for all alternatives and its consistency rates. It is also possible to operate with negative weighting, inferring Benefits, Opportunities, Costs, and Risks. The tool implements Group Decisions, using the geometric mean to combine criteria comparisons from selected stakeholders.

An Improved Triggering Updating Method of Interest Message with Adaptive Threshold Determination for Directed Diffusion Routing Protocol

“…Because of the effective combination of qualitative and quantitative approaches, it has been popularly practiced in the fields of performance evaluation, engineering planning, program sequencing, economic management, etc. [36]. In this paper, the complex correlation and subordination between interest messages and information exchange rates are combined into a three-level analysis structure model by AHP, and the threshold determination can be converted into computing the relative weights of information exchange rates to the update threshold.…”
