Publications about the project
This paper elaborates the open scientific question with practical relevance to producing enterprises at which service level an article of a production warehouse should be provided to production. The objective of this paper is to develop a decision supporting logistic model calculating the service level of an article which should be achieved when considering the follow-up costs of a stockout situation (stockout costs) on the one hand and the costs of the logistic organization on the other hand (i. e. warehousing). The new logistic model’s elaborative work is based on known stock out cost types (i. e. by REICHMANN) as well as on the characteristic curves for the service level and the delivery delay developed by WIENDAHL and NYHUIS.

Up to the present day, literature has already dealt with stockout-costs, but methods to quantify these costs have not been developed until now. The absence of these kinds of methods prevents an efficient logistic positioning between stockout-costs and the costs for holding safety-stocks. The costs for safety-stocks in a warehouse to provide a desired service-level can already be determined, but the stockout-costs connected with a desired service-level cannot be quantified yet. This article introduces a mathematical function to quantify the costs in a company’s production caused by missing material, depending on the amount of missing material and its missing time.
