This model investigates the variable production cost for a production house; under a two-echelon supply chain management where a single vendor and multi-retailers are involved. This production system goes through a long run system and generates an out-of-control state due to different issues and produces defective items. This model considers the reduction of the defective rate and setup cost through investment. A discrete investment for setup cost reduction and a continuous investment is considered to reduce the defective rate and to increase the quality of products. Setup and processing time are dependent on lead time in this model. The model is solved analytically to find the optimal values of the production rate, safety factors, optimum quantity, lead time length, investment for setup cost reduction, and the probability of the production process going out-of-control. An efficient algorithm is constructed to find the optimal solution numerically and sensitivity analysis is given to show the impact of different parameters. A case study and different cases are also given to validate the model.

“…Then, Ouyang and Chuang [19] investigated a continuous review inventory model and presented that the lost sales rate can be reduced by an effective capital investment. In addition, Annadurai and Uthayakumar [20] developed ordering policy for periodic review inventory model with controllable lead time by reducing lost sales rate. Recently, Uthayakumar and Parvathi [21] investigated a two-stage supply chain system with order cost reduction and credit period incentives for deteriorating items.…”

“…In the above discussion, we concentrate on some applications about the basic inventory models. This paper develops an inventory model in uncertain environment from Annadurai and Uthayakumar's () model by using fuzziness of annual demand as fuzzy number of annual demand and statistic‐fuzzy number of annual demand. We develop two models in the fuzzy sense.…”

This paper investigates a periodic review fuzzy inventory model with lead time, reorder point, and cycle length as decision variables. The main goal of this study is to minimize the expected total annual cost by simultaneously optimizing cycle length, reorder point, and lead time for the whole system based on fuzzy demand. Two models are considered in this paper: one with normal demand distribution and another with a distribution-free approach. The model assumes a logarithmic investment function for lost-sale rate reduction. Furthermore, two separate efficient computational algorithms are explained to obtain the optimal solution. Some numerical examples are given to illustrate the model.
