项目摘要

The logistic performance and in particular the schedule reliability of a production system is still a major competitive factor for industrial enterprises. Despite of the vital significance, many companies still face problems achieving their target schedule reliability. The reason lies within the numerous factors influencing the schedule reliability as well as the complex interdependencies in logistic systems.Describing logistic relationships by the use of models provides a simple and practical way for designing a logistic system. Factors influencing the schedule reliability are systematically structured and their impact on schedule reliability is described in terms of quantitative, mathematical equations. By applying this model, it is possible to find the most effective measure for increasing the schedule reliability. Furthermore, it is possible the estimate the effect of the measure on the schedule reliability before implementing the measure.Therefore, the target of the submitted research project is to develop a quantitative impact model describing the lateness of manufacturing orders of a single production system. The model calculates the empirical distribution of the lateness of the processed manufacturing orders. The input for the model is e.g. the sequencing rule, the work in process, or the backlog. Combining multiple models will allow describing the evolution of lateness in any logistic network.

对于工业企业来说，物流绩效，特别是生产系统的进度可靠性仍然是一个主要的竞争因素。尽管具有重要的意义，但许多公司仍然面临着实现目标进度可靠性的问题。其原因在于影响物流系统调度可靠性的因素众多，以及物流系统中复杂的相互依赖关系。利用模型来描述物流关系，为物流系统的设计提供了一种简单实用的方法。系统地构造了影响计划可靠性的因素，并用定量的数学方程描述了它们对计划可靠性的影响。通过应用该模型，可以找到提高调度可靠性的最有效措施。此外，在实施措施之前估计措施对进度可靠性的影响是可能的。因此，提交的研究项目的目标是开发描述单个生产系统的制造订单延迟的定量影响模型。该模型计算了加工制造订单延迟的经验分布。模型的输入是排序规则、正在处理的工作或待办事项。结合多个模型将允许描述任何物流网络中延迟的演变。
