Lead optimization basic rules

In order to determine the best actions in every situation we will consider the two heuristics we preferred in Section 4.2. the Silver-Meal-like production rale and the (x,T)-rale. The use of the optimal policy becomes much more complicated than in the previous section, because of the introduction of a more complicated state which has to include the population size and therefore more complicated transition probabilities, all together leading to a production rule which can hardly be of practical use. In the heuristics, the penalty costs again are a basic element. The penalty costs are now defined as the expected volume of missed revenues as a result of departed customers if an order is delivered one period too late. If the revenues and the stochastic processes which govern the decrease and increase of the population size are known, the penalty costs can be estimated in a simple way and the heuristics can be used in the same way as in Section 4.2. We will explain this by stud3dng an example.
