Modeling a Mining Transportation System using Integrated Methods: A Case Study of PT Vale Indonesia Tb

Development of an efficient mining transportation system using a combination of AHP and QDF methods as well as QDF and SWOT ones has been widely exercised. However, these three methods have not been interactively applied. Therefore, the present study aimed to determine the mode of mining transportation system using fuzzy AHP, QDF, and SWOT methods in an integrated and sequential manner. To this end, data sources were obtained from in-depth interviews with eight consumer representative respondents, five respondents from PT Vale Indonesia Tbk as a mining company, and three respondents from the Transportation Department in Luwu Timur District in Indonesia. Data analysis began with weighting and determining the hierarchy of product value criteria (i.e. fuzzy AHP), then defining the house of quality of these criteria via QDF, and finally establishing the strategy to achieve the results through SWOT. Ultimately, by land mode was recommended through widening roads and road bends as well as making separate roads and road alignments on Malili-Sorowako Public Road. The strategy that PT Vale Indonesia Tbk can take is to carry out the operation in a one work package, to plan for optimal placement of roadblocks and cat eyes, and to arrange for licensing in an integrated manner.
