The total yearly costs of medicine usage in The Netherlands are increasing year after year. The Dutch government tries to get this increase under control by price regulations, which forces pharmaceutical manufacturers in The Netherlands to manufacture and distribute more efficiently. In this...

We study a vehicle routing problem with soft time windows and stochastic travel times. In this problem, we consider stochastic travel times to obtain routes which are both efficient and reliable. In our problem setting, soft time windows allow early and late servicing at customers by incurring...

We consider a single item assembled from two components. One of the components has a long lead time, high holding cost and short review period as compared to the other one. We assume that net stocks are reviewed periodically, customer demand is stochastic and unsatisfied demand is backordered....
