This paper deepens the understanding regarding the practical usability of cost management models for purchasing decisions, and provides a framework for determining a desired complexity of cost management in different purchasing environments. The complexity is defined along three dimensions identified in literature and the different purchasing environments stem from an adaptation of Kraljic＇s （1983） matrix.展开更多

Unsuitable blasting pattern may lead to unwanted events such as poor fragmentation, back break and fly rock. Multi attribute decision making(MADM) can be useful method for selecting the most appropriate blasting pattern among previously performed patterns. In this work, initially, from various already performed patterns, efficient and inefficient patterns are determined using data envelopment analysis(DEA). In the second step, after weighting impressive attributes using experts' opinion, elimination Et choice translating reality(ELECTRE) was used for ranking the efficient patterns and recognizing the most appropriate pattern in the Sungun Copper Mine, Iran. According to the obtained results, blasting pattern with the hole diameter of 15.24 cm, burden of 3 m, spacing of 4 m and stemming of 3.2 m has selected as the best pattern and has selected for future operation.展开更多

By the end of 2016, there were 231 million people over the age of 60 in China, accounting for 16.7% of the total population. About 150 million people aged 65 and over make up 10.8 percent of the total population. China is expected to enter the peak period of population aging by 2035. Therefore, the government as a single pension service main body management pattern already can not adapt to our country entered the aging society, mobilize and fostering social organizations to participate in the pension services is to build perfect endowment service system, satisfy people pension service demand model of a kind of indispensable. In view of the development of social organizations has just started in our country, there exist many problems and difficulties, so this article USES the ISM method, for social organizations to participate in research and analyze influence factors of pension services, and then find out the social organization in the process of participation in pension service problems, put forward effective solutions.展开更多

Application of TOPSIS （technique for order Performance by similarity to ideal solution） method for evaluation and regulation of alternatives based on hierarchically structured criteria of qualitative character by multiple experts to intellectually support decisions made in staff management issues is reviewed in the article. Candidate selection experiment based on criteria system formed using TOPSIS method for evaluation of candidates during solution of hiring problems reviewed and obtained results were compared with results obtained using Matlab program package.展开更多
