Nowadays every decision-maker from production industries is more concern with the system improvement. They also focused in adopting different marketing strategies to make their production system as successful system. In the current study, a production quantity model is explored for deteriorating item by considering volume flexibility. Multivariate demand is considered in the model which is the function of promotional efforts, selling price, and credit period. An additional investment is made by the decision-maker to improve the system quality and reduce the deterioration rate. Whole of the analysis is carried out under the effect of inflation. Profit function of the current study is nonlinear so a search algorithm is suggested to obtain the optimal values of selling price, production time, and production rate. At the end, numerical analysis along with sensitivity is executed to validate the model and to observe the effect of different parameters on the optimal solution of the problem.
