今天的制造计划方法通常侧重于生产系统的技术组成部分。对生产工人个人技能的系统整合，虽然具有很大的优化潜力，但目前还没有得到进一步的考虑。这对于知识密集型生产过程（例如专用车辆制造）尤其重要，其特点是要执行大量可变和手工工作步骤。即使在这种情况下，也没有充分考虑到能力对业务目标的影响。在这种背景下，已经开发出一种方法，允许系统地将个人特定能力集成到过程规划中。通过一个车间生产仿真模型对该方法进行了验证。结果表明，系统的能力提升计划会导致短期内的额外成本，因为对“在职”生产人员的培训需要付出更多的努力。另一方面，基于能力的车间生产工艺规划的长期效益是通过盈亏平衡点来计算的。可以证明“技术节约”的特点是工作人员的灵活性增加和工作效率提高。
Today’s manufacturing planning methods usually focus on the technical components of a production system. Up to now, a systematic integration of individual skills of the production workers is not further considered, even though it bears high optimization potentials. This is critical especially for knowledge-intensive production processes (e.g. specialized vehicle construction) characterized by a high amount of variable and manual work steps to be performed. Even in such cases the influence of the competencies to the operational targets is not sufficiently taken into account. Against this background, a method has been developed allowing the systematic integration of person-specific competencies for process planning. The method was evaluated with a simulation model of a workshop production. The results illustrate that a systematic competence-enhancing planning leads to additional costs in short-term due to the higher effort for the training of production personnel “on the job”. On the other hand, the long-term benefits of a competence-based process planning for workshop production were calculated by a Break-Even-Point. “Economies-of-skills” characterizing the resulting increased flexibility and greater work efficiency of the working personnel could be demonstrated.
