Carlsson and Fullér (Fuzzy Sets Syst 122: 315–326, 2001) introduced the notations of lower possibilistic and upper possibilistic mean values of a fuzzy number, and investigated its relationship to the interval-valued possibilistic mean and variance. In this paper, we introduce the new notations of lower magnitude and upper magnitude mean values of a fuzzy number. The new interval-valued magnitude...
In view of characteristics of south-to-north water diversion supply chain, from the perspective of time, Markov chain theory is applied to the research of information flow response time distribution of the eastern route south-to-north water diversion supply chain, in order to provide a reference for the operation of this project. This study shows that information collection and processing efficiency...
