Selecting Appropriate Dimension Stone in Processing Plants using the Fuzzy Delphi Analytic Hierarchy Process

Selecting the most appropriate dimension stones has always been one of the vital issues in processing plants which stone is processing. This study aims to develop a new hierarchical model to evaluate and rank the dimension stone with the use of effective and major criteria such as beauty and durability, stone slab ability, supply chain, profitability, domestic and foreign market demand, and environmental factors and simultaneously, considering subjective judgments of decision-makers. The proposed approach is based on the fuzzy Delphi analytic hierarchy process method to calculate the effectiveness of the criteria and rank the dimension stone by decision-makers. This model is utilized for some stone process plants to assess and rank some famous Iranian granite. Then, the most appropriate stones for stone processing process plants are ranked. The ranking results showed that Chayan black granite with a 0.24 value, is the best stone to sawing in studied stone process plants. Finally, it was deduced that the most appropriate selection of dimension stone can reliably be done using the developed approach according to the most important effective criteria.
