Prioritizing Preventative and Repair Measures of Conveyor Belt Equipment Pieces Using Fuzzy TOPSIS Technique (Case Study: Pelletizing Plant of GolGohar Mining and Industrial Company)

Abstract

KeywordsAbstract Increasing efficiency does not necessarily require the use of expensive technologies. Sometimes implementing properly management and engineering principles, employing skilled and efficient manpower, planning appropriately, and identifying effective priorities can increase efficiency and reduce costs. Conveyor belt equipment pieces are category components which carry heavy materials in factories and mines. Downtime of the pieces have many costs for the factory. Identification of parts of conveyor belts, taking preventative and repair measures and prioritizing measures in order to increase efficiency and reduce cost for downtime conveyor belt are important. In this study, using fuzzy TOPSIS technique to prioritize the preventative and repair measures of conveyor belt equipment pieces factory in the pelletizing plant of GolGohar mining and industrial company have been discussed. In this regard, the main and ten other parts of conveyor belt along with their practical roles are identified from viewpoint of engineers and technicians who deal with them. Besides, intended preventative and repair measures are identified according to previous records. Then maintenance repair parts and expert opinions are discussed to prioritize the preventative measures. Finally, recommendations are provided for increasing efficiency of conveyor belt and reducing cost and repair time.
