“…They rectified a minor error in the work of Richter [18,19] and, consequently, their model produces a lower cost because of the residual inventory assumed in Richter [18,19]. Kozlovskaya et al [30] rectified the model of El Saadany and Jaber [29] and provided the optimal policy. They showed that the optimal policy depends on the disposal rate.…”

The mathematical modeling of reverse logistics inventory systems ignores the fact that returned items may arrive out of sequence, i.e., with different number of remanufacturing times. Moreover, such modeling assumes that the retuned items may retain the same quality upon recovery regardless of how many times they have been previously remanufactured. This paper develops a new mathematical expression of the percentage of retuned items that can be remanufactured a finite number of times. The proposed expression is modeled as a function of the expected number of times an item can be remanufactured in its lifecycle and the number of times an item can be technologically (or optimally) remanufactured based on its quality upon recovery. The model developed in this paper considers joint production and remanufacturing options. The return rate is a varying demand-dependent rate, which is a decision variable with demand, product deterioration, manufacturing, and remanufacturing rates being arbitrary functions of time. The model considers the initial inventory of returned items in the mathematical formulation, which enables decision-makers to adjust all functions and input parameters for subsequent cycles. Illustrative examples indicate that dependent purchasing price of recovery items and the incorporation of remanufacturing investment cost significantly impact the optimal remanufacturing policy.

In the present study, we formulate an inventory model with waste disposal cost under the intuitionistic fuzzy environment. To optimize the best inventory policy under the intuitionistic fuzzy environment, the alpha-cut approach is used for the defuzzification of all intuitionistic fuzzy decision variables. This study aims to reduce the total inventory cost and adjust the waste outcomes during the production processes to keep a clean and green climate, which will be cost-effective for any organization, both environmentally and economically. A numerical example is presented regarding the proposed intuitionistic fuzzy model to validate the methodology.

“…The economic order quantity model analytically obtained the optimal cycle length of the retailer and shown that a perishable good act similarly to a non-perishable good with unit holding cost equal to the ratio of contribution margin to lifetime. Kozlovskaya et al (2017) studied the repair and waste disposal problem and provided a complete solution to this complex problem. Rossi et al (2017) proposed an approach for including the finite capacity constraint in the EOQ model to study the context of single-machine multi-item systems.…”

PurposeThis paper proposes a new inventory model with inspection policy because in practice the received orders may contain non- conforming (NC) items. So, a buyer who receive an order from a supplier should use an inspection policy.Design/methodology/approachThe inspection policy is assumed to be zero-defect single sampling. Under this policy a lot is accepted only if no defect has been identified in the inspected sample. The fraction of NC is assumed to be a random variable following a Binomial distribution and the number of NC items detected by inspection assumed to be a random variable, which follows a hypergeometric distribution. Order quantity and sample size are the two decision variables. A solution procedure is presented for the proposed model. The proposed procedure presents the optimal solution.FindingsNumerical examples presented to illustrate the procedure outlined for the proposed model and its applicability. The results of numerical examples and comparing them with traditional EOQ model reveal that by the proposed model, the buyer could reduce total cost that shows the efficiency and validity of the proposed model.Originality/valueThe novelty of this paper is the new proposed model that considers inspection policy in inventory management. The proposed model determines sample size as well as order quantity to consider both subject of inventory management and quality control, simultaneously.
