چکیده

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.

Today, in fierce competition with advanced and the current growth technology, one of the most important issues in the material handling industry is the choice of method and appropriate equipment. Depending on the type of material, equipment type may be different [1]. In GolGohar pelletizing plant of mining and industrial company, conveyor belt equipment is used to transport the materials. Industrial conveyor belts are portable devices that are used to transport material between two fixed points  intermittently or continuously [2]. In general, mechanical tools for continuous transport of materials in certain directions are available in different types, capacities and speeds. Today conveyor belts are the most widely used and are considered very important elements in production systems and automation units, with their varying capabilities and efficiencies as an integral part of industry. The wide use of conveyor belt in mines, factories, and public places proves their usefulness in making the activity easy [3]. Due to its nature and importance in production line, gender and price, a conveyor belt is  one of the most sensitive equipment pieces. Hence, it is important to know how to buy, inspect, quality control and warehouse it [4]. Conveyor belt equipment in pelletizing plant is key equipment in the material handling. To maintain this equipment, maintenance and repair system are required to identify all preventative and repair measures for each  piece. Appropriate conveyor selection can reduce manpower requirements, electricity costs, production time, prices and delivery time, and thus increase profitability and productivity [5].

Material handling costs are significant in manufacturing, amounting to approximately 15% to 70% of the total manufacturing cost [6].

By reviewing and prioritizing preventative measures, experts and operators will be able to increase duriability of parts, reduce the rate of failure and improve efficiency of conveyor belts. This increases the efficiency of the conveyor belt besides saving money.

The aim of this study is to identify and prioritize preventative and repair measures for conveyor belt equipment using Fuzzy MCDM approach (FMCDM) in a pelletizing plant. First, a review on preventative and repair measures of  parts ofconveyor belt is provided. Then Fuzzy TOPSIS method is presented as used in this research and finally the results of prioritization will be presented and analyzed.
