blood supply chain management is one of the mainchallenges in healthcare system. optimal locationof blood donation camps is one of the key factors in optimizing the bloodsupply chain. disruption in location of blood donation camps because ofdisasters will have a negative impact on the entire supply chain. thispaper develops a generalized network optimization model for the complex supplychain of...

  The importance of reliable supply is increasing with supply chain network extension and just-in-time (JIT) production. Just in time implications motivate manufacturers towards single sourcing, which often involves problems with unreliable suppliers. If a single and reliable vendor is not available, manufacturer can split the order among the vendors in order to simultaneously decrease the supp...

The retailers within a supply chain management are the most important player as it has direct contact with customers. Customers source of money and information for entire management. equilibrium condition forward backward is tight until reliable. But sometimes hide from manufacturer this unreliability starts to propagate Blockchain technology one secure decentralized systems prevent unreliabili...

We demonstrate the importance of using a sufficiently long time horizon analysis when modeling inventory systems subject to supply disruptions. Several publications use singleperiod newsboy models to study supply disruptions, and we show that such models underestimate the risk of supply disruptions and generate sub-optimal solutions. We examine a firm with an unreliable supplier that is subject...

The risk of supply disruption increases as firms seek to procure from cheaper, but unproven, suppliers. We model a supply chain consisting of a single buyer and two suppliers, both of whom compete for the buyer’s order and face risk of supply disruption. One supplier is comparatively more reliable but also more expensive, while the other unreliable one is cheaper and faces higher risk of disrup...
