We envision a future economy where e-markets will play an essential role as exchange hubs for commodities and services. Future e-markets should be designed to be robust to manipulation, flexible, and sufficiently efficient in facilitating exchanges. One of the most important aspects of designing an e-market is market mechanism design. A market mechanism defines the organization, information exc...

the world health organization’s (who’s) world health report 2010, “health systems financing, the path to universal coverage,” promoted universal health coverage (uhc) as an aspirational objective for country health systems. yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

in today’s competitive transportation systems, passengers search to find traveling agencies that are able to serve them efficiently considering both traveling time and transportation costs. in this paper, we present a new model for the traveling salesman problem with multiple transporters (tspmt). in the proposed model, which is more applicable than the traditional versions, each city has diffe...

In this paper we suggest a new framework for constructing mathematical models of market activity. Contrary to the majority of the classical economical models (e.g. ArrowDebreu, Walras, etc.), we get a characterization of general equilibrium of the market as a saddle point in a convex-concave game. This feature significantly simplifies the proof of existence theorems and construction of the adju...

DC distribution systems are a promising alternative to existing AC systems. They connect customers local energy sources without conversion, thus reducing power losses. However, the unique features of impose strict requirements for system operation compared AC. Within context liberalized market, this article demonstrates three market designs—an outcome comprehensive engineering design framework—...

By running life tests at higher stress levels than normal operating conditions, accelerated life testing quickly yields information on the lifetime distribution of a test unit. The lifetime at the design stress is then estimated through extrapolation using a regression model. To conduct an accelerated life test efficiently with constrained resources in practice, several decision variables such ...

this paper extends endogenous growth models through augmenting it with government budget and oil revenues as well as the effect of public investment efficiency on long run growth of private and government consumption and import for an oil producing economy. based on the extracted model, the optimal growth rate of government current expenditure (or consumption) has a positive relation with the e...

This paper presents the application of enhanced opposition-based firefly algorithm in obtaining the optimal battery energy storage systems (BESS) sizing in photovoltaic generation integrated radial distribution network in order to mitigate the voltage rise problem. Initially, the performance of the original firefly algorithm is enhanced by utilizing the opposition-based learning and introducing...
