In the science of operation research and decision theory, selection is the most important process. Selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. The multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literatur...

Purpose – The purpose of this paper is to define and describe Pugh matrix analysis as a method for decision making when there are multiple criteria that must be factored into a decision. Design/methodology/approach – Using theory and example, the author relates the use of Pugh matrix analysis to the successful selection of prioritized criteria in digital library projects. Findings – Pugh matrix...

Big data sizes are constantly increasing. Big data analytics is where advanced analytic techniques are applied on big data sets. Analytics based on large data samples reveals and leverages business change. The popularity of big data analytics platforms, which are often available as open-source, has not remained unnoticed by big companies. Google uses MapReduce for PageRank and inverted indexes....

Through quantitative evaluation of the data and information compiled in the literature review and survey, an explicitly defined list of alternatives and decision criteria to evaluate rehabilitation alternatives was developed for culverts 122 centimeter (48 inch) in diameter or smaller. Relative weights of each criterion were assigned in comparison to the defined alternatives, thereby allowing a...

Because trade-offs (Pareto optimal, non-dominated or efficient sets) are not properties of criteria or objectives, but of sets of feasible alternatives, the proper task of decision making is to work on designing proper sets of alternatives rather than assuming them to be fixed and given a priori. In fact, decision making takes place only when multiple criteria and trade-offs are present. All th...

Keywords decision analysis life-cycle impact assessment (LCIA) methods multiple attribute multiple-criteria decision analysis (MCDA) normalization Summary Life-cycle impact assessments (LCIAs) are complex because they almost always involve uncertain consequences relative to multiple criteria. Several authors have noticed that this is precisely the sort of problem addressed by methods of decisio...
