Determination and prioritization of effective criteria for establishment of gypsum boards units in Iran using paired comparisons method

Considering the high cost of the methodical construction of buildings and the use of engineered and safe materials; the structure such as gypsum board has been interested of experts in wood and construction industry. The reason is important features such as low production costs and high earthquake resistance. Moreover, it’s important to determine effective criteria for decision-making for the establishment of industrial units aimed of optimal use of raw materials, the production process and approaches to reduce costs and waste. To achieve this, paired comparative analysis method was selected and after initial studies, field surveys and interviews with experts, 5 main criteria and 32 important sub-criteria were identified. After that, the paired comparisons questionnaires were prepared and filled out by academics and a number of managers and experts in wood and construction industry. The results revealed that among the first level criteria, material and product, economic and financial criteria have the highest priorities, respectively. Besides, sub-criteria of ensuring the sustainable supply of gypsum resources, raw materials costs, background of the mineral composites, background of the construction industry, distance from the gypsum resources, content of the gypsum resources finally the amount of sale had the highest priorities, respectively.
