Computational approach to fuzzified profit optimisation of inventory flow in supply chain with deteriorating items

In this paper, we make a fresh attempt to discuss fuzzified profit optimisation of inventory in supply chain with deterioration and power form stock dependent demand. After applying Zadeh's extension principle and centroid method, a system of nonlinear equation has been developed and consequently solved by using fast converging Newton‐Raphson (N‐R) method. The optimum profit of a fuzzified inventory control system as an important performance measure has been computed and sensitivity analysis has been also presented to demonstrate the use of the model under consideration.
