Prioritizing the effective factors on projectile performance by combination of Analytical Hierarchy Process (AHP) method and design of experiment of Taguchi Case study: selected aerospace industries

The purpose of this research is to prioritize the effective factors in projectile performance. Prioritizing of these factors whit combination of Analytical Hierarchy Process (AHP) method and design of experiment Of Taguchi help designers to develop the performance of projectile structure. According to this that since now، researcher tried to increase the performance of projectile whit change in every factors separately، so in this paper tried whit combination of AHP method and design of experiment of Taguchi، analyzed and prioritized all the effective factors in projectile performance simultaneously. For this purpose first by design of experiment Of Taguchi the influence of every these factors on two criteria of range and drift were calculated and then by AHP method these factors were prioritized. By considering of equal weight for both range and drift، the result shows between 11 factors، Firing Angle whit value of 0. 3398، Muzzle Velocity whit value of 0. 2918 and Burning Time whit value of 0. 1257 were the most influenced factors in projectile performance respectively. Propellant Weight and Wind Velocity factors whit value of 0. 0104 and 0. 00092 were ranked in tenth and eleventh priority respectively.
