Inventories, facilities and transportation are considered to be the important tools of supply chain management. The efficiency of any manufacturing unit can be increased if the above elements are under proper control. In today's scenario one of the significant fields in supply chain management...

Risk interaction network (RIN), a system comprised of risk (nodes) and triggering relations (edges) between risks, changes the likelihood of occurring and also the impact of a risk. An issue of optimizing RIN, allowing for the risk response actions of weakening risk interactions, departs from...
