Nowadays green retail practices are increasing in number. In this paper, an inventory model is formulated with retail investments in green operations including variable holding cost. In the proposed model, the demand rate depends on selling-price as well as green concern level. The main objective of the study is to find optimal replenishment time and optimal green concern level by considering profit maximization. Here, the effect of greening-level on purchasing-price and selling-price is shown. By investing in green operations, a retailer creates considerable impact on profitability. As the greening level increases, the profit of a retailer increases. Product with lower deterioration rate would increase the profit. Based on the above consideration, the mathematical model is designed by allowing carbon tax. Then, the model is explored by numerical examples. Mathematica software is used to obtain global maximum solution to the optimal cycle time and optimal greening-level. A sensitivity analysis with respect to major parameters is performed in order to access the stability of the model. The paper concludes with conclusions and an outlook of possible future directions is depicted.


A two-echelon inventory model with stock-dependent demand and variable holding cost for deteriorating items
Pervin, Magfura; null, null; Kumar Roy, Sankar; Wilhelm Weber, Gerhard (American Institute of Mathematical Sciences (AIMS), 2017)
In this study, we develop an inventory model for deteriorating items with stock dependent demand rate. Shortages are allowed to this model and when stock on hand is zero, then the retailer offers a price discount to customers who are willing to back-order their demands. Here, the supplier as well as the retailer adopt the trade credit policy for their customers in order to promote the market competition. The retailer can earn revenue and interest after the customer pays for the amount of purchasing cost to ...
An analysis of manufacturer benefits under vendor-managed systems
Savaşaneril Tüfekci, Seçil (Informa UK Limited, 2010-01-01)
Vendor-Managed Inventory (VMI) has attracted a lot of attention due to its benefits such as fewer stock-outs, higher sales, and lower inventory levels at the retailers. Vendor-Managed Availability (VMA) is an improvement that exploits the advantages beyond VMI. This article analyzes the benefits beyond information sharing and assesses the motivation for the manufacturer (vendor) behind joining such a program. It is shown that such vendor-managed systems provide increased flexibility in manufacturer's operat...
A single supplier-single retailer system with an order-up-to level inventory policy
Solyali, Oguz; Süral, Haldun (2008-09-01)
We consider a two-level vendor-managed system in which external demand occurs only at a retailer and a supplier replenishes the retailer employing an order-up-to S policy over T periods. We present an O(T-3) algorithm to coordinate the system when S is known. We also show that S can be optimized in O(aT(3)) time for an input parameter a.
A Novel Interactive Fuzzy Programming Approach for Optimization of Allied Closed-Loop Supply Chains

In recent years, the relationship between companies and suppliers has changed with the continuous rise in environmental awareness and customer expectations. In order to fulfill customers' needs, the actors in a Supply Chain (SC) network sometimes compete and sometimes cooperate with each other. In SC management, both competitive and collaborative strategies have become important and have required different points of view. In a collaborative environment, companies should strive for common targets with mutual...
A Maximization Model To Satisfy The Perceived Quality In Education
Kuruüzüm, Ayşe (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2001)
The education sector has a special position within the service industry, due to relatively long-term customer loyalty and repurchase behavior. These characteristics increase the importance of perceived and presented quality levels related to customer satisfaction in this sector. The main purpose of this research is to model empirically the relationships between perceived service quality and satisfaction in elementary and secondary education. The fieldwork of the research was conducted in a private school. F...
