Modeling Emergency Logistics Location-Allocation Problem with Uncertain Parameters
Hui Li,Xiangyu Ge +1 more
TL;DR: In this paper , an uncertain multiobjective model is developed within the framework of uncertainty theory to model the emergency facility location-allocation problem with uncertain parameters, which minimizes time penalty cost, distribution cost and carbon dioxide emissions.

Optimum Locations of Switching Centers and the Absolute Centers and Medians of a Graph
TL;DR: It is shown that the optimum location of a switching center is always at a vertex of the communication network while the best location for the police station is not necessarily at an intersection.

Management Models and Industrial Applications of Linear Programming
TL;DR: In place of a survey or evaluation of industrial studies, two broad issues which are relevant to all such applications will be discussed, including the use of linear programming models as guides to data collection and analysis and prognosis of fruitful areas of additional research, especially those which appear to have been opened by industrial applications.

Expected value of fuzzy variable and fuzzy expected value models
Baoding Liu,Yian-Kui Liu +1 more
TL;DR: A novel concept of expected values of fuzzy variables is presented, which is essentially a type of Choquet integral and coincides with that of random variables, and is designed to calculate the expected value of general fuzzy variable.
