With Sequence dependent set-up times companies are facing the challenge to trade off the objectives output rate, throughput time, WIP and schedule reliability. Up to now no model exists that describes the impact of set-up cycles on these logistic objectives with general validity.The research project aims at two major goals:I. Development of a quantitative model that describes the impact of set-up cycles on output rate and throughput times as a function of the mean WIP using operating curves.II. Development of a quantitative model that describes the impact of set-up cycles on lateness as a function of the mean WIP and the production times of the set-up families. With the achievement of the first major goal, the impact of set-up cycles on the logistic objectives WIP, throughput time and output rate would be modeled for the first time in a quantitative and generally valid way.The achievement of the second major goal makes it possible to model the influence of set-up cycles on lateness. The main result is the maximum and the mean absolute lateness as a function of WIP and the production times of the set-up families.The overall goal therefore is to model all four logistic objectives as a function of WIP and of the production times of the set-up families. This will allow companies for the first time to decide on the basis of comprehensive quantitative information for or against sequencing with set-up cycles and to set the parameters of the set-up cycles in a logistic positioning.

随着顺序依赖的设置时间公司面临的挑战，权衡目标的产出率，吞吐时间，可持续性和进度可靠性。到目前为止，还没有一个模型能够描述装配周期对这些物流目标的影响，并且具有普遍的有效性。开发一个定量模型，该模型描述了设置周期对输出速率和吞吐时间的影响，作为使用操作曲线的平均吞吐量的函数。开发一个定量模型，描述了设置周期对延迟的影响，作为设置家庭的平均生产时间和生产时间的函数。随着第一个主要目标的实现，第一次定量地、普遍有效地模拟了装配周期对物流目标时间、通过时间和产出率的影响，第二个主要目标的实现使得装配周期对延迟的影响模型化成为可能。主要结果是最大和平均绝对迟到作为在制品和装配系列生产时间的函数。因此，总体目标是将所有四个物流目标建模为在制品和装配系列生产时间的函数。这将使公司首次能够根据全面的定量信息决定是否使用设置周期进行排序，并在物流定位中设置设置周期的参数。
