Supplier competition and investment of effort are important concerns in supply base design. They are affected not only by the number of suppliers, but also by their capacity profile. This paper studies supply base design in terms of the number and capacities of suppliers, considering both supplier competition and investment of cost-reduction effort. We analyze a buyer who invests in capacities ...

Supply chains are facing different types of uncertainty associated with today‘s business environment. Uncertainty in the supply chain may arise from a number of sources such as demand and supply interruptions, production/logistics capacity changes and lead time variability. To cope with this problem and lessen the impacts of such uncertainties, an effective strategy is to incorporate flexibilit...

cost of quality analysis is emerged as an effective tool for the industrial managers for pinpointing the deficiencies in the system as well as for identifying the improvement areas by highlighting the cost reduction opportunities. however , this analysis will be fully effective only if it is further extended to identify the cost incurred in ensuring quality in all areas of the supply chain incl...

In this research work, a wholesaler-retailer-customer supply chain model for a deteriorating item is considered, where the retailer's warehouse in the market place has a limited capacity. The retailer can rent an additional warehouse (rented warehouse) if needed, with a higher rent compared to the existing warehouse (own warehouse). The customers' demand of the item is linearly influenced by th...

One of the most important points in a supply chain is customer-driven modeling, which reduces the bullwhip effect in the supply chain, as well as the costs of investment on the inventory and efficient transshipment of the products. Their homogeneity is reflected in the inventory-routing problem, which is a combination of distribution and inventory management. This paper considers a multi object...

In industries like health care, consumer goods and agriculture, shortages are widely observed and the consequences can be costly. One of the main drivers of such shortages is the uncertain nature of supply and demand. To reduce uncertainties, sufficient information about supply and demand can be obtained by gathering relevant data (e.g., auditing suppliers and conducting market research). In th...

The increased cost of accessing energy and the effects on economic growth (GDP) across regions is one of grave concern [1]. The Cost implication of energy supply often shapes regional energy policies across the globe. This paper presents an empirical investigation into the relationship between energy generation and economic growth, while also investigating probable threats to sustainable energy...

Supply chain management (SCM) is an emerging field that has commanded attention and support from the industrial community. Supply chain (SC) is defined as the chain linking each entity of the manufacturing and supply process from raw materials through to the end user. In order to increase supply chain effectiveness, minimize total cost, and reduce the bullwhip effect, integration and coordinati...

As additive manufacturing (AM) evolves to become a common method of producing final parts, further study of this computer integrated technology is necessary. The purpose of this research is to evaluate the potential impact of additive manufacturing improvements on the configuration of spare parts supply chains. This goal has been accomplished through scenario modeling of a real-life spare parts...
