项目摘要

Companies are forced to concentrate on 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. In this research proposal an integrated planning method for the integrated production and outbound distribution planning problem will be developed. Most of the existing planning methods in this research field are production or transport oriented with a low integration level of these two sub-problems. Thus, there is a need for conceptual and methodological support for solving the integrated planning problem.The goal of this research proposal is the development of a new integrated planning method for the focused part of the supply chain with a high integration level and an improved performance. Two separate strategies for the development of integrated planning methods and a number of milestones are defined to reach this goal. Before the development of integrated planning methods will start, there is a need to generate a basic underlying model. The existing planning methods uses different underlying models, which prevents a competitive comparison of performance indicators of the overall planning results. Therefore, the first sub-goal is the development of a basic model for evaluation of new planning methods, which will be developed in this research project, and the comparison with existing methods.The application of evolutionary algorithms is the first strategy for the development of an integrated planning method. Already known methods from the production scheduling and from transportation planning will be used for generating a starting plan. The evolutionary algorithm generates and optimises alternative solutions based on this starting plan respecting the restriction of each sub-problem. For the evaluation of the alternative plans a suitable function is required.The main characteristics of the second strategy is a multistage decomposition of the sub-problems production scheduling and transportation planning and a new structure for the problem solving process. Starting with a clustering each sub-problem will be solved and optimised separately in each cluster. Subsequently, there is a two step integration procedure in order to obtain an overall integrated planning result. Finally, the integrated planning methods developed will be evaluated using the basic model. Furthermore, there will be additional investigations regarding sensitivity of integrated planning results.

由于全球市场的竞争形势，公司被迫专注于核心能力并与供应链中的专业合作伙伴密切合作。这些合作伙伴往往有不同且相互冲突的目标。因此，只有内部流程优化，而没有整个供应链的优化规划结果。集成计划是一种供应链管理概念，可以实现供应链范围内的优化以达到总体目标。在本研究提案中，将开发一种用于综合生产和出库分销规划问题的综合规划方法。该研究领域现有的规划方法大多以生产或运输为导向，这两个子问题的整合程度较低。因此，需要概念和方法上的支持来解决集成计划问题。本研究提案的目标是为供应链的重点部分开发一种新的集成计划方法，该方法具有高集成度和改进的性能。为了实现这一目标，定义了两个独立的综合规划方法开发策略和许多里程碑。在开始开发综合规划方法之前，需要生成一个基本的底层模型。现有规划方法采用不同的底层模型，无法对总体规划结果的绩效指标进行竞争性比较。因此，第一个子目标是开发一个用于评估新规划方法的基本模型，该模型将在本研究项目中开发，并与现有方法进行比较。进化算法的应用是发展规划方法的首要策略。综合规划方法。生产调度和运输规划中已知的方法将用于生成起始计划。进化算法基于这个考虑每个子问题限制的起始计划生成并优化替代解决方案。为了评估替代计划，需要一个合适的函数。第二种策略的主要特征是子问题生产调度和运输规划的多级分解以及问题解决过程的新结构。从聚类开始，每个子问题将在每个聚类中单独解决和优化。随后，有一个两步集成过程，以获得总体集成规划结果。最后，将使用基本模型对所开发的综合规划方法进行评估。此外，还将对综合规划结果的敏感性进行额外的调查。
