Therefore, the development of appropriate planning methods for optimization of the respective supply chains is constantly growing in importance. A specific problem in the context of humanitarian operations is the supply of relief items to the affected areas after the occurrende of a sudden change in demand or supply, for example, due to an epidemic or to unexpected shortages, durng an ongoing humanitarian action. When such overlapping disasters occur, goods must be relocated to existing depots in a way which enables rapid suppply to regions with new and urgent demand. At the same time, ongoing operations have to continue, i. e., the other regions should not suffer from shortages, and possible future emergencies must be taken into account. This is a planning situation under uncertainty as it is not known in advance if and where a disruption - and hence additional demand - will occur. In this paper, an optimization model for such situations is developed based n penalty costs for non-satishied demand. A rolling horizon approach for solving the model is presented, and it is shown that taking into account the possibility of future disruptions can helb to balance inventories and to reduce total non-served demand.

Since the necessary probabilities for machine failures and similar operational events on the floor can easily be integrated in the simulation model, in order to analyze, how initial plan performs in these situations. The influence of unforeseen events in daily production cannot be modeled within mathematical optimization without consuming large amounts of computation time. We show a possible way to use simulation to evaluate and enhance a production plan. We illustrate the developed process using a real-world use-case of medium complexity and can show, that simulation is able to evaluate the robustness of a given pro-optimizes production plan.

In their concrete application a leading company from the construction supply industry has to make a decision on setting up of a spare part logistic. Three future alternatives (negative, constant, positive market growth) on market trends are simulated with a Monte Carlo simulation by considering a given demand history and possible locations for storage facilities were isolated by applying the Steiner-Weber method. Finally solving a mixed-integer formulation of the Uncapacitated-Facility-Location-Problem gives information on opening/closing new/existing storage facilities by minimizing all relevant costs. The results of this approach, containing information about a cost-based evaluation of all business related decision criteria, were examined with a sensitivity analysis.
