one of the most important measures needed to be done in times of crisis is to optimize the allocation and distribution of resources among individuals. time is a critical factor effective to increase the number of people rescued by the relief activities.in this paper, we present a relief vehicle routing model in the affected area which uses covering tour approach to reduce total response time. a...

The literature on portfolio analysis assumes that the securities returns are random variables with fixed expected returns and variances values (see Bachelier [1], Briec et al. [4] and Markowitz [10]). However, since investors receive efficient or inefficient information from the real world, ambiguous factors usually exist in it. Consequently, we need to consider not only random conditions but a...

The open nature of the World Wide Web makes evaluating webpage credibility challenging for users. In this paper, we aim to automatically assess web credibility by investigating various characteristics of webpages. Specifically, we first identify features from textual content, link structure, webpages design, as well as their social popularity learned from popular social media sites (e.g., Faceb...

In this research work, a wholesaler-retailer-customer supply chain model for a deteriorating item is considered, where the retailer's warehouse in the market place has a limited capacity. The retailer can rent an additional warehouse (rented warehouse) if needed, with a higher rent compared to the existing warehouse (own warehouse). The customers' demand of the item is linearly influenced by th...

This paper discusses the optimization of emergency resource scheduling for major railway emergencies under multiple uncertainties while considering in demand, reserve, and transportation costs resources. We introduce a novel approach that integrates stochastic mathematical programming, interval parameter fuzzy programming to study uncertain interactions coupling. A two-stage credibility-constra...

The formation of macroeconomic policy is conceptualized as on-going process of interaction between private individuals and a centralized policymaker. This interaction is inherently strategic in nature and lends itself to a gametheoretical treatment. Starting from the basic principle of rational expectations, the analysis advances a theoretical perspective on the related concepts of macroeconomi...

Absurd? Yes. However, this false belief – that children are somehow naturally more able to use technology and are also somehow more Internet savvy – is a common one. Problems with Internet information and in more traditional forms of information are well documented. Professors of entering college undergraduates observe that students “are ill prepared to function in a technological and informati...
