designing dynamic demand networks considering agility and security measures

responsibility in demand networks is one of the most important measures of performance. the concept of agility and flexibility in service and production. variety and changes in demand need more flexible network design that can cope with potential shortage and delay. this paper presents new mathematical model to optimize the design of demand network when there are highly variable demands. it also takes security measures into the accounts that lead to the less discoverable nodes and centers in the network. the final mixed integer linear programming model has been applied on a real system and the results have been discussed at the end of the paper.
