Abstract: Conveyor belts are required to transport different types of materials in industries under varying operating conditions. A number of materials for such belts are available in the market. However, it is impossible to identify one such material, which will perfectly respond to all such requirements in a given environment. Hence arises the question of optimization. The present paper is based on one such optimization technique known as analytic hierarchy process (AHP). It considers a number of alternative materials as well as design criteria and arrives at the most suitable material. The algorithm calculates the priority vector (PV) values by eigen-vector method of pair-wise comparison. These PV values are calculated through an iterative process, and are accepted if the concerned matrices yield consistency ratios (CR) below a specific limit. Finally, composite priority (CP) values are calculated, and the alternatives are ranked according to their CP values. The algorithm is coded in FORTRAN language. The program is general, and can be used to handle smaller or larger number of criteria and alternatives as well.
