Healthcare services are often provided to a country as a whole, though in many cases the available resources can be more effectively targeted to specific geographically defined populations. In the case of malaria, risk is highly geographically heterogeneous, and many interventions, such as insecticide-treated bed nets and malaria community health workers, can be targeted to populations in a way...

Background and Objectives: A sudden jump in blood demand during natural disasters may have strong negative impact on the performance of blood supply chain. Appropriate response to emergency situations requires predictive approach to determining the optimal allocation of blood supply chain resources for various disaster scenarios. The present study, thus, presents an optimization model aimed at ...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

In randomized experiments, a single random allocation can yield groups that differ meaningfully with respect to a given covariate. Furthermore, it is unfeasible to control the allocation with respect to a moderate number of covariates. As a response to this problem, Morgan and Rubin [1, 2] proposed an approach based on rerandomization to ensure that the final allocation obtained is balanced. Ho...

Estimation is one of the most critical areas in software project management life cycle, which is still evolving and less matured as compared to many other industries like construction, manufacturing etc. Originally the word estimation, in the context of software projects use to refer to cost and duration estimates only with software-size almost always assumed to be a fixed input. Continued lega...

This paper presents a novel reliable hierarchical location-allocation model where facilities are subject to the risk of disruptions. Based on the relationship between various levels of system, a multi-level multi-flow hierarchy is considered. The heterogeneous probabilistic disruptions are investigated in which the constructed facilities have different site-dependent and independent failure rat...

This paper revisits the put-call parity condition for European options, on both non-dividend paying and dividend stocks, in presence of fixed costs spreads. It demonstrates that becomes a set inequalities under these conditions. A model patterned Roll cost bid-ask spreads is postulated, its estimation using generalized method moments (GMM) approach, suggested. Finally, spreads, options non-divi...
