Objectives: The production-distribution inventory problem has two main sectors namely production and distribution. In this paper, the nonlinearmathematical model of extended star-ring supply chain network is developed.Methods: Planning a distribution network plays a vital role in minimizing the total expenditure of the project; to prove this, a ring network topology is taken to supply goods to the SWs and extended star network topology to supply goods to the selling stores. However, setting up separate SWs for each and every selling store will be highly expensive. Hence, keeping the minimum number of SWs is very important. Selection of SWs from the available SWs is done by replacing diverse values based on the distance limitation.Results: The suggested model is validated with the mathematical problem, and the optimum set of SWs is identified from the result. The result has been substantiated using analytic hierarchy process. Conclusion: The system of optimum number of SWs is obtained from the result.

Dual Channel Supply Chain

Integrating strategic and tactical decisions to location-allocation and green inventory planning by considering e-commerce features will pave the way for supply chain managers. Therefore, this study provides an effective framework for making decisions related to different levels of the dual-channel supply chain. We provide a bi-objective location-allocation-inventory optimization model to design a dual-channel, multi-level supply chain network. The main objectives of this study are to minimize total cost and environmental impacts while tactical and strategic decisions are integrated. Demand uncertainty is also addressed using stochastic modeling, and inventory procedure is the periodic review . We consider many features in inventory modeling that play a very important role, such as lead time, shortage, inflation, and quality of raw materials, to adapt the model to the real conditions. Since a dual-channel supply chain is becoming more important for sustainable economic development and resource recovery, we combine online and traditional sales channels to design a network. We generate five test problems and solve them by using the augmented ε-constraint method. Also, the Grasshopper optimization algorithm was applied to solve the model in a reasonable time for a large size problem. In order to provide managerial insights and investigate the sensitivity of variables and problem objectives with respect to parameters, sensitivity analysis was performed.

Vendor Management

In order to reduce inventory cost effectively, the vendor management inventory (VMI) is studied in this paper. The inventory problem of supply chain is described, the model of VMI is established, and the optimal solution is obtained. The research in this paper can enrich the supply chain management theory, and help enterprises improve inventory management level.

This project focuses on two-level closed-loop supply chains with defective items. The objective of this project is to develop and design a model that minimizes the total expected cost per unit time, which includes set-up costs, holding costs, transportation/shipping costs, and screening costs of the integrated two-level close-loop supply chain. The model also finds the optimum order size and optimum number of shipments. The buyer screens the products received from the vendor to find the defective items. The holding costs of the defective items at the buyer's end is paid by the vendor. After the screening process, the defective items are shipped back to the vendor and the vendor has to carry the shipping costs of the defective items. Two scenarios may arise: where both the vendor and buyer are domestic or international, where vendor and buyer are located in two different countries. In the case of an international supply chain, exchange rate between two countries has also been considered. In current world since the business growing fast, the inventory management of any business enterprise improving their performance financially by minimizing the holding cost. The analysis shows how the percentage of defective item affects the total expected cost. The project work has an important involvement for improvement in the vendor-buyer correlated high-tech supply chain industries.

Responses to bioterrorism require rapid procurement and distribution of medical and pharmaceutical supplies, trained personnel, and information. Thus, they present significant logistical challenges. On the basis of a review of the manufacturing and service supply chain literature, the authors identified five supply hain strategies that can potentially increase the speed of response to a bioterrorism attack, reduce inventories, and save money: effective supply chain network design; effective inventory management; postponement of product customization and modularization of component parts; coordination of supply chain stakeholders and appropriate use of incentives; and effective information management. The authors describe how concepts learned from published evaluations of manufacturing and service supply chains, as well as lessons learned from responses to natural disasters, naturally occurring outbreaks, and the 2001 US anthrax attacks, can be applied to design, evaluate, and improve the bioterrorism response supply chain. Such lessons could also be applied to the response supply chains for disease outbreaks and natural and manmade disasters.
