Companies are forced to concentrate on their core competencies and a close collaboration with specialized partners in a supply chain due to the competitive situation on global markets. These partners often have different and conflictive goals. Thus, there is only an internal process optimisation and not an optimised planning result for the entire supply chain. Integrated planning is a supply chain management concept which enables a supply chain wide optimisation to reach the overall goals. The focus of this thesis is the integrated production and outbound distribution planning problem. Most of the existing planning methods in this research field are production or distribution oriented with a low integration level of these two suba problems. There is a need for conceptual and methodological support for solving this integrated planning problem. Thus, the overall objective of this thesis was the development of a new integrated planning method for the focused part of the supply chain with a high integration of suba problems and an improved performance. As a result of an intense analysis of the state of the art it can be stated that there are several gaps in the field of integrated planning of production and outbound distribution. Consequently, a number of secondary objectives were defined in order to fill the identified gaps. Two of these secondary objectives were the development of a system of objectives and the development of a representation scheme for classification of existing planning models for the integrated problem considered. Furthermore, it turned out that each of the existing solution methods uses an individual planning model. This prevents a comparison of accuracy and performance between different solution methods. Therefore, another secondary objective was the development of a unified planning model, which was further used for evaluation regarding performance and stability of planning results. The developed integrated planning method is based on a framework, which was also developed in this thesis. The main characteristics of the framework is a multia stage decomposition and integration procedure of the suba problems production and distribution scheduling. The integrated planning method applies this new multia stage structure for the problem solving process and uses already known solution methods to solve the respective suba problems. A real world oriented scenario was used to demonstrate the performance of the developed method. The evaluation shows that the overall costs of planning results generated by solution methods are up to 26% higher than the overall costs of the planning results generated by the developed integrated solution method. Furthermore, in a sensitivity analysis was shown that there is a positive impact on overall costs applying the integrated solution method developed within a wide range of cost parameters. Moreover, the general working principle of the frameworks shows a high flexibility regarding the solution methods to be defined and thus a simple transferability and application in a specific scenario in the field of integrated planning of production and outbound distribution.
