A volume flexible inventory model with trapezoidal demand under inflation

This article explores an economic production quantity model (epq) model for deteriorating items with time-dependent demand following trapezoidal pattern taking the volume flexibility into account. we have also considered the inflation and time value of money. the solution of the model aims at determining the optimal production run-time in order to maximize the profit. the model is also illustrated by means of numerical experiment. further,the effects of different parameters are analysed by performing sensitivity analyses on the optimal policy.
