DEXi is an educational Multi Criteria Decision Aid (MCDA) computer program aimed at interactive development of qualitative multi-criteria and hierarchical decision models and the evaluation of options. The Decision Desktop software, or d2 for short, is one of the software modules being developed in the Decision Deck project. It is a desktop, client/server application which has integrated severa...

background: the two most frequently diagnosed cancers among women worldwide are breast and cervical cancers. the objective of the present study was to classify the different countries based on the death rates from sex specific cancers. methods : in this cross-sectional study, we used dataset regarding death rate from breast, cervical, uterine, and ovarian cancers in 190 countries worldwide repo...

A method of minimizing rankings inconsistency is proposed for a decision-making problem with rankings of alternatives given by multiple decision makers according to multiple criteria. For each criteria, at first, the total inconsistency between the rankings of all alternatives for the group and the ones for every decision maker is defined after the decision maker weights in respect to the crite...

Immediate roof caving in longwall mining is a complex dynamic process, and it is the core of numerous issues and challenges in this method. Hence, a reliable prediction of the strata behavior and its caving potential is imperative in the planning stage of a longwall project. The span of the main caving is the quantitative criterion that represents cavability. In this paper, two approaches are p...

When using graphical models for decision making, a fundamental question is whether one is ready to make a decision (stopping criteria), and if not, what observations should be made to better prepare for a decision (selection criteria). In this paper, we review the notions of entropy and expected utility, which are commonly used for this purpose, and contrast them with a newly introduced notion,...

Over the past three decades substantial research has been dedicated to the task of providing theoretical models for group decision processes. Unfortunately, many models remain grounded in single-period decision contexts. The current work investigates an extremely basic process approach to multi-criteria multi-period group decision-making. The time-series model considered incorporates factors re...
