Examination of the sensitivity of an operation schedule with perturbation analysis

Abstract

An algorithm is presented to calculate the validity range of deterministic similarity of a sample path of a discrete event dynamic system when a single perturbation is introduced at the operation times. Based on the calculated range, sensitivity analysis concerning both the gradient of the throughput and some special technological feasibility of an operation schedule can be analysed. The algorithm is recommended in a manufacturing environment, when technology intensive products are produced in small lots. The implementation of the algorithm in an automated steel manufacturing process is also presented.
