in this paper, we develop a capacitated location-covering model considering interval values for demand and service parameters. we also consider flexibility on distance standard for covering demand nodes by the servers. we use the satisfaction degree to represent the constraint of service capacity. the proposed model belongs to the class of mixed integer programming models. our model can be redu...

conclusions these results revealed that cirrhosis produce prolonged qt interval and sour cherry extract has an ameliorating effect on qt prolongation probably via its antiarrhythmic property. results results were analyzed by using student t-test and one-way anova. p < 0.05 was considered as significant level. the qt interval was calculated using the bazettʼs formula and corrected qt (qtc) was o...

In this paper we consider modelling of composite material with inclusions where the elastic material properties of both matrix and inclusions are uncertain and vary within prescribed bounds. Such mechanical systems, involving interval uncertainties and modelled by finite element method, can be described by parameter dependent systems of linear interval equations and process variables depending ...
