The dramatic deregulatory reforms in US electricity markets increased competition, resulting more complex prices compared to other commodities. This paper aims investigate and compare the overall time-varying multifractality efficiency of four major regions: Mass Hub, Mid C, Palo Verde, PJM West. Multifractal detrended fluctuation analysis (MFDFA) is employed better quantify intensity self-simi...
Israel Kirzner lays the foundations of entrepreneurship as driving force market process by referring to alertness, uncertainty, and plan coordination. His approach, following footsteps Mises Hayek, legitimizes entrepreneurial creativity profit-making heart dynamic process. He argues that an accurate insight into economic system requires exploring how dynamics work in society. This statement con...
In this paper, a new method is proposed for fuzzy structural reliability analysis; it considers epistemic uncertainty arising from the statistical ambiguity of random variables. The proposed method, namely, fuzzy dynamic-directional stability transformation method, includes two iterative loops. An internal algorithm performs the reliability analysis using the dynamic-directional stability trans...
In today’s economy, manufacturing plants must be able to operate efficiently and respond quickly to changes in the product mix and demand.[1] Layout design has a significant impact on manufacturing efficiency. Initially, it was treated as a static decision but due to improvements in technology, it is possible to rearrange the manufacturing facilities in different scenarios. The Plant layout...
in this paper, we have calculated the environmental efficiency for india, turkey, egypt and iran. the results show that iran’s environmental efficiency has experienced a decreasing trend from 1991 to 2007and india, turkey, egypt and iran have the highest environmental efficiency, respectively. we also have investigated the environmental kuznets curve for this period using data envelopment analy...
