Abstract According to the concept of “flexible surge capacity,” hospitals may need be evacuated on two occasions: (1) when they are exposed danger, such as in war; and (2) contaminated, during Covid-19 pandemic. In former, entire hospital must evacuated, while latter, becomes a pandemic center necessitating transfer its non-contaminated staff, patients, routine activities other facilities. Such...

In production planning (PP) periods with excess capacity and growing demand, the manufacturers have two options to use the excess capacity. First, it could do more changeovers and thus reduce lot sizes, inventories, and inventory costs. Second, it could produce in excess of demand in the period and build additional inventory that can be used to satisfy future demand increments, thus delaying th...

We study the role of partial flexibility in large-scale dynamic resource allocationproblems, in which multiple types of processing resources are used to serve multipletypes of incoming demands that arrive stochastically over time. Partial flexibilityrefers to scenarios where (a) only a small fraction of the total processing resourcesis flexible, or (b) each resource is capab...
