In this paper, we propose a minmax multicommodity netflow model for routing in healthcare wireless body area networks (WBAN). The model is aimed at minimizing the worst power consumption of each bio-sensor node placed in the body of a patient plus the total heating costs subject to flow conservation and maximum capacity energy constraints. The model is formulated as a mixed integer linear progr...

We present a hybrid method to efficiently solve Google Machine Reassignment problem (MRP), the problem proposed at ROADEF/EURO Challenge 2012 competition. We study, implement, combine and empirically examine different local search neighborhoods to solve the set of available instances. Intensification and diversification of search is achieved through the suitable change of the objective function...

Let $kgeq 1$ be an integer, and let $G$ be a graph. A {it$k$-rainbow dominating function} (or a {it $k$-RDF}) of $G$ is afunction $f$ from the vertex set $V(G)$ to the family of all subsetsof ${1,2,ldots ,k}$ such that for every $vin V(G)$ with$f(v)=emptyset $, the condition $bigcup_{uinN_{G}(v)}f(u)={1,2,ldots,k}$ is fulfilled, where $N_{G}(v)$ isthe open neighborhood of $v$. The {it weight} o...

following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...

Adverse perceptions of neighborhood safety, aesthetics and quality including access to resources can induce stress and may make individuals more sensitive to cardiopulmonary effects of air pollution exposure. Few studies have examined neighborhood perceptions as important and modifiable non-chemical stressors of the built environment that may exacerbate effects of air pollution on cardiopulmona...

This paper investigates the structure of qualitative capacities, which are monotonic increasing set functions ranging on a finite totally ordered scale equipped with an orderreversing map. More specifically, we study whether these qualitative set-functions can be viewed as classes of more particular set functions, namely possibility measures, paralleling the situation of quantitative capacities...

An uncapacitated facility location problem considers a set of n warehouses W and a set of m stores S. Each warehouse w has a fixed cost fw, and the transportation cost from warehouse w to store s is given by cws. The problem is to find a subset of warehouses and an assignment of warehouses to stores in order to minimize the fixed and transportation costs. Observe that once the warehouses are se...
