Ethical decision making is difficult. Decision makers with cognitive, emotional, social, and philosophical limits have incomplete information about ambiguous, dynamic situations, where the consequences of action are uncertain. This paper describes Dioptra, a decision support system that can help people become more effective ethical decision makers. Dioptra adds structure to the decision process...

This paper deals with multiple criteria decision making problem with incomplete information when multiple decision makers (Multiple Criteria Group Decision Making: MCGDM) are involved. Usually decision makers (DMs) are willing or able to provide only incomplete information, because of time pressure, lack of knowledge or data, and their limited expertise related with problem domain. There have b...

Decision making in environmental problems is a complex task due to multiple and often conflicting criteria, varying measurements, qualitative and quantitative input parameters, and lack of exact data. In this paper, we propose a multi-criteria decision making (MCDM) model based on an integrated fuzzy approach in the context of Hazardous Waste Recycling (HWR). The proposed method: (a) takes into...

Project portfolio selection is one of the most important decision-making problems for most organizations in project management and engineering management. Usually project portfolio decisions are very complicated when project interactions in terms of multiple selection criteria and preference information of decision makers (DMs) in terms of the criteria importance are taken into consideration si...

D organizations may incur inefficiencies because of scheduling issues associated with competition among decision makers (DMs) for limited resources. We analyze the decentralization cost (DC), i.e., the ratio between the Nash equilibrium cost and the cost attained at the centralized optimum. Solution properties of a dispatching-sequencing model are derived and subsequently used to develop bounds...

In group decision making with linguistic information, the decision makers (DMs) usually provide their assessment information by means of linguistic variables. In some situations, however, the DMs may provide fuzzy linguistic information because of time pressure, lack of knowledge, and their limited attention and information processing capabilities. In this paper, we introduce the concepts of tr...

This article proposes a calibrated individual semantic (CIS)-based failure mode and effect analysis (FMEA) to deal with the risk evaluation of industrial internet platforms (IIP) from four perspectives: network security, data processing capability, equipment performance, openness. The novelty CIS model is based on deviation between linguistic terms numerical values calibrate scales decision-mak...

Inefficiencies naturally form as organizations grow in size and complexity. The knowledge required to address these inefficiencies is often stove-piped across different organizational silos, geographic locations, professional disciplines. Crowdsourcing provides a way tap into the experiences of diverse groups people rapidly identify more effectively solve inefficiencies. We developed prototype ...

In the consensus reaching process (CRP) permitting negotiation, efficiency of negotiation is affected by order with decision makers (DMs), time, and number moderators. this paper, sorted against DMs considering time initiated into making, which can improve speed effectiveness consensus. Based on opinion dynamics (opinion evolution), uniform normal distributions are used to describe uncertainty ...

This article proposes a bidirectional feedback mechanism for consensus in group decision making (GDM) driven by the behavior of makers (DMs), which is discriminated with flexible harmony degree as one three possible states: (1) ‘tolerance behavior’; (2) ‘rationalist and (3) ‘conflict behavior’. The first two states are to be resolved reaching process round recommendations discordant DMs. Howeve...
