Abstract
The significance of schedule reliability as a particularly important logistic objective is indisputable. In comparison to the objectives WIP, utilisation and throughput time, the modelling of the schedule reliability is, however, not very advanced until now. This paper transfers the process capability indices used in quality management to schedule reliability and demonstrates two methods for depicting the schedule reliability as a function of its influencing parameters.
Notes
1. Different from the rest of the paper we follow the convention of quality management and use the Greek letters µ and σ and not their Latin counterparts to denote the mean and standard deviation of a variable.
