Manufacturers offering a wide range of different product variants have to deal with the problem that their customers demand for more and more influence on the configuration of products. These customer requirements as well as technical innovations lead to an increasing variety of parts and, therefore, to more complex processes in production and logistics. In order to work against this trend, common parts are applied. These common parts reduce the variety of parts without limiting the possible configurations visible to the customers. Thus, companies need to evaluate the assets and drawbacks of the use of common parts in order to find the common part strategy leading to the lowest manufacturing costs. Here, the determination of the manufacturing costs in production and logistics is especially challenging.In this thesis, a method for evaluating different common part strategies in production and logistics is presented. The method consists of three parts. First, the production and transportation network of the manufacturer is structured and dimensioned. Thereby, the minimal manufacturing costs of a given common part strategy are determined. The second part of the solution method deals with the planning and evaluation of production areas with assembly lines. Thirdly, the internal logistic network is structured and dimensioned to precisely define the logistic costs for some specific production sites. All three parts consist of several mathematical models or heuristic methods integrated in a hierarchical procedure. The whole method is tested and the industrial application is proven.
