 Classical facility location models assume that once optimally located and set up, facilities will operate as planned, smoothly, and without interruption. In reality, though, operations seldom go as planned; interruptions, unscheduled downtime and failures occur every once in a while, with unplanned and unbudgeted disruption costs as a consequence. [ ... ]  Supply chain management used to be relegated to the logistics department of businesses and hardly thought of as matters concerning the top-level management. In his 2004 paper, Joseph L. Cavinato points out five sub-networs within the supply chain that need special attention:Physical – the actual movement of goods, shipping and warehousing Finance, Information, Relations, Innovation. [ ... ]  The starting point for this paper is the question of how to define and find critical locations in a transport network. A network node is vulnerable if loss or degradation of a small number of links diminishes the accessibility of the node. A network link is critical if loss or degradation of the links diminishes the accessibility of the network or of particular nodes [ ... ]  The severity of supply chain disruptions stems from supply chain design characteristics and supply chain mitigation capabilities: Supply Chain Design: supply chain density,supply chain complexity, node criticality. Supply Chain Mitigation Capability: recovery capability, warning capability. [ ... ]  Supply chain risks can include a number of different issues, and the article structures these issues along three dimensions: 1) the Supply Chain itself, 2) Risk Management processes and 3) Types of Risk. [ ... ]  Daniel Ekwall’s thesis combines theories from criminology with theories from logistics and supply chain management to examine cross-over points or antagonistic gateways between the legal and illegal logistics system from a supply chain perspective. [ ... ]  Drivers of supply chain vulnerability are 1) supply-side risk 2) demand-side risk, 3) catastrophic risk. Sources of risk are a) customer dependence and b) supplier dependence, d) supplier concentration and d) single sourcing and e) global sourcing. [ ... ]  The book Strategies for Building Successful Global Businesses, by the INSEAD-Wharton Alliance on Globalizing, contains 6 articles on managing risk and uncertainty. Today I will look at one of these articles that deserves further mentioning. [ ... ]  Are you gambling with your supply network? You should be aware that the supply network is inherently vulnerable to disruption and the failure of any one element in it could cause the whole network to fail. Actions to improve security can be classified into three categories: Physical security, Information security, Freight security. Actions to improve resilience can be be divided into: Flexibility, Redundancy. [ ... ]  Supply chain event management (abbreviated as SCEM) is a consideration of all possible occurring events and factors that can cause a disruption in a supply chain. [ ... ] | | |
