Abstract

Group decision is usually made using ordinal and cardinal methods. Group decision making is used in this paper by applying binarycomparison, and two calculating methods were used including Calculation of λmax and comparable particular victor from analysis matrix Dmxm and Calculation of particular victor from matrix Dmxm by approximate method. The methods were selected based on the ideas of a number of sophisticated mine experts. In order to measure the efficacy in the company, the costs for human resources, energy, materials, and the capital were taken into account. Then, the costs were evaluated and prioritized. Having taken them into consideration, priorities in cost management were determined. The major purposes behind that were increasing total productivity and determining its formula in Iran's Central Iron Ore Company in Bafq.
