... model was constructed to handle the SSRP with port disruption uncertainties, for which we derive tractable counterparts under the polyhedral ambiguity sets. Findings The results show that the size of ambiguity set, confidence level and risk-aversion parameter can significantly affect the optimal...

... uncertainties about product valuation and consumption states in the advance period and are overconfident about the probability of a good state, we study how the service provider chooses the optimal sales strategy among the non-advance selling strategy, the advance selling and disallowing cancelation strategy...

..., considering the uncertainty in the SC brings the issue closer to the real world. In this study, virtualization costs including security, recall and energy consumption in SC optimization are considered. Highlights Investigates the role of IoT for virtual supply chain profit optimization and mathematical...

... fuzzy uncertainty. Originality/value In this paper, the authors extend a class of solutions for cooperative games that all have some egalitarian flavour in the sense that they assign to every player some initial payoff and distribute the remainder of the worth v(N) of the grand...

... uncertainty and high risks. Fuzzy set theory has been used to address various aspects of project uncertainty, but with key practical limitations. This study aims to develop and apply a novel Pythagorean fuzzy sets (PFSs) approach that overcomes these key limitations. Design/methodology/approach The study...

...Fei Zhang; Xiao-Hua Zhou; Jiafu Su; Sang-Bing Tsai; Yu-Ming Zhai Purpose The purpose of this paper is to examine how signals of uncertainty in the media affect retail investor decisions and initial public offering (IPO) underpricing through theoretical and empirical methods. Design/methodology...

... is first applied to aid in the evaluation and refinement of these various available criteria to obtain the most important and relevant criteria for the oil and gas industry. The grey systems theoretic concept is adopted to address the subjectivity and uncertainty in human judgments. The grey-Shannon...

... for this dynamic decision situation. This research breaks new ground by proposing a decision analytic methodology where quantitative analysis can be applied to address problems where technologies are implemented with unintended consequences and where the precautionary principle is applied. Uncertainty...

... condition with the requirement the sellers will increase refund. Similar results are found when uncertainty is incorporated into demand and return quantity. In addition, how the sellers’ optimal refund is affected by market parameters and market volatile factors is discussed. Specially, the correlation...

...Lei Guo; Huimin Li; Peng Li; Chengyi Zhang Purpose – The purpose of this paper is to find how those uncertainty factors influence transaction costs generated and to identify ways to minimize the transaction costs borne by the construction owner. Design/methodology/approach – The literature...

... on how cybernetics principles may be applied on an individual basis to provide a more holistic way of coping with the challenges of everyday life in the early twenty-first century. The author sees how he can live a balanced life, cope with uncertainty, live with courage, move beyond dualities and develop...

...George J. Klir Presents an overview of currently recognized theories of imprecise probabilities and their possible extensions. It is shown how the theories are ordered by their levels of generality. A summary of current results regarding measures of uncertainty and uncertainty‐based information...

...Wang Qing Yin; Ren Biao; Wang FengLi We introduce the concepts of information, uncertainty information, systems and uncertainty systems, analyze the intension of these concepts, and point out the differences and connections among various concepts of systems. We put forward a mathematical method...

...Wu Chen In this paper, the author puts forward an incongruous imprecise reasoning model in expert systems from the viewpoints of pansystems methodology and suggests some new algebra algorithms for propagating uncertainty factors in this model. It identifies the existing reasoning models...

...Robert Vallée We consider a dynamical linear differential (or recurrent) system whose initial state is given only by a probability density. The Shannon information entropy, associated with the probability density, is considered as a global uncertainty index giving a measure of the uncertainty about...

...D.A. Bell; J.W. Guan; C.M. Shapcott The Dempster‐Shafer theory of evidence gives a solid basis for reasoning about situations characterized by uncertainty. A key feature of the theory is that propositions are represented as subsets of a set which is called a hypothesis space. This power set along...

... uncertainty‐based information that are beyond the narrow scope of classical information theory. Introduces well‐justified measures of uncertainty in fuzzy set theory, possibility theory, and Dempster‐Shafer theory. Shows how these measures are connected with the classical Hartley measure and Shannon entropy...
