Enhancing service providers reliability by mitigating supply chain risk : the case of telecommunication networks
Service providers rely on the continuity of their service to sustain their businesses. While at first glance it may seem that service providers are not as dependent on their supply chain as product companies are, a closer look of some relevant systems shows that a stable and resilient supply chain …

Scheduling and routing of service trucks and planning of resource replenishment locations for winter roadway maintenance
… readily available at all times due to stochastic service disruptions. For instance, the operations of trucks are sometimes subject to failure, possibly due to traffic congestion or mechanical breakdowns. A stochastic dynamic fleet management model is developed to assign available trucks to cover …
