The purpose of this study is to find the percentiles of fuzzy numbersand to demonstrate their applications, which include finding weightedmeans, dispersion indices, and the percentile intervals of fuzzy numbers. Thecrisp approximations of fuzzy numbers introduced in this paper are new andinteresting for the comparison of fuzzy environments, such as a variety of economic,financial, and engineeri...

Weeds are a serious problem of chickpea cultivation in rain-fed areas of Iran and economic feasibility of crop production is mostly challenged by the method of control. In this study, two types of weed control strategies which are common in the country, including hand removing and hand removing + mechanical application, were compared with application of general herbicide (Glyphosite) using a sp...

Palladium is an element of PGM group that has significant physical properties. This leads to more attention to this metal. Due to vast applications of palladium in industry and its usage in jewelry, its price plays an important role in economic. Therefore, forecasting its price is crucial subject in economic and engineering design. This paper proposes the model GM(1,1) to predict the Palladium ...

Particle swarm optimization (PSO) has received increasing attention in solving multi-objective economic dispatch (ED) problems in power systems because of parallel computation, faster convergence, and easier implementation. This paper presents a detailed overview of multi-objective particle swarm optimization (MOPSO) and provides a comprehensive survey on its applications in power system econom...

Two major events have affected the monetary regime in the United Kingdom in recent years, namely the introduction of inflation targeting, and the granting of operational independence to the Bank of England. In this paper we examine what impact, if any, these events have had on inflation expectations. A series of Granger causality tests are used in order to examine the causal relationship betwee...

I is widely recognized that developing countries in the tropics that harbor a large fraction of the world’s biodiversity could, in principle, obtain substantial benefits from their biodiversity. The challenge has been to harness the economic value of sustainable uses of biodiversity in order to justify the conservation of habitat in its natural state. Promising strategies for meeting this chall...
