the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

in this paper, a robust model presented is developed for hub covering flow problem in which hubs have capacity. this problem has two objective functions converting to a single-objective problem by using weighting method. firstly, the problem will be formulated in a certain case. then, by considering the demand as a non-random variable, it will be modeled by robust optimization. finally, by usin...

internet is one of the most promising future energy infrastructures which could enhance energy efficiency and improve system operating flexibility. In analog to the micro-grid, micro energy internet puts more emphasis on distribution level and consumer side. The concept and design principles of smart micro energy internet are proposed to accommodate micro-grids, distributed poly-generation syst...

Smartphone applications that continuously monitor user context are becoming popular for applications ranging from health-care to lifestyle monitoring to participatory sensing. Unfortunately, these emerging apps make poor use of the already scarce energy resources because they continually wake the CPU and other mobile device components for periodic sensing, computation, and communication. We rep...

The goals of hub location problems are finding the location of hub facilities and determining the allocation of non-hub nodes to these located hubs. In this work, we discuss the multi-modal single allocation capacitated p-hub covering problem over fully interconnected hub networks. Therefore, we provide a formulation to this end. The purpose of our model is to find the location of hubs and the ...
