Optimal product design of textile spinning industry using simulated annealing

Abstract

In this paper, we have tried to manufacture cotton yarns with requisite strength by choice of suitable raw material and process parameters. In an attempt to achieve a yarn having optimal strength, a constrained optimization problem is formulated with the relation between raw material and yarn properties. Frydrych’s theoretical model of yarn strength is used as objective function of the optimization problem. The simulated annealing (SA) method has been used to solve the optimization problem by searching the best combination of raw material and process parameters that can translate into reality a yarn with the desired strength. The results show that SA is capable of identifying the set of parameters that gives optimum yarn strength.
