performance of a supply chain highly depends on its suppliers and therefore, appropriate selection of them is of great importance. this paper presents an integrated model of an mcdm method and a mathematical programming in order to select suppliers and determine lot sizes in the supply chain. the proposed framework comprises two main sub-models; the qualitative sub-model seeks to evaluate the s...

The problem of chunk-based resource allocation for the uplink of Long Term Evolution is investigated. In this paper, a combined order using the promethee method and analytic hierarchy decision for chunk allocation algorithm is proposed. The utility of each order is sorted based on promethee method approach so that the utility of each order could be approximated as the average of all criteria on...

This paper studies a public goods economy with a certain tax system to finance public goods, involving multiple public goods and a private good called money. In this economy, coalitions are allowed to improve upon a current allocation within their initial endowments and the tax revenue levied upon the complementary coalition according to the tax system, under a rule restricting the resulting al...

For optical waveguides with high index contrast and sharp corners, high order full-vectorial mode solvers are difficult to develop, due to the field singularities at the corners. A recently developed method (the so-called BIENtD method) based on boundary integral equations (BIEs) and Neumannto-Dirichlet (NtD) maps achieves high order of accuracy for dielectric waveguides. In this paper, we deve...

WHEN A COLLEGE GRADUATE decides to pursue a higher degree at a particular institution, one of the first challenges she faces is finding an apartment. Most institutions have on-campus housing available that is often subsidized and hence more appealing than its alternatives. Usually there are several types of on-campus housing and the attractiveness of each type changes from person to person. The...

The cost of reproduction theory posits that there are trade-offs between current and future reproduction because resources that are allocated to current offspring cannot be used for future reproductive opportunities. Two adaptive reproductive strategies have been hypothesized to offset the costs of reproduction and maximize lifetime fitness. The terminal investment hypothesis predicts that as i...

Background Setting priorities and the subsequent allocation of re­ sources is a major ethical issue facing healthcare facili­ ties, including the Veterans Health Administration (VHA), the largest integrated healthcare delivery network in the United States. Yet despite the impor tance of priority set­ ting and its impact on those who receive and those who provide care, we know relatively little ...

Recent studies identified several distinct genetic lineages within the softshell turtle genus Pelodiscus that could represent valid species. Traditionally, Pelodiscus was regarded to comprise only a single species (P. sinensis). These softshell turtles are economically the most important chelonians of the world, with hundreds of millions of specimens traded as food every year. Moreover, Pelodis...

We investigate the e®ect of introducing costs of complexity in the n -person unanimity bargaining game. As is well-known, in this game every individually rational allocation is sustainable as a Nash equilibrium (also as a subgame perfect equilibrium if players are su±ciently patient and if n > 2). Moreover, delays in agreement are also possible in such equilibria. By limiting ourselves to a pla...

Proposed Running Head: The RESET test and allocation models Abstract: We discuss some issues which arise if the RESET test is used to validate the functional form of the equations in an allocation model. The simple application of this test, equation, by equation, is inappropriate on various grounds. The appropriate formulation of the RESET test in a full systems context requires care. This is d...
