ABSTRACT: Production scheduling involves a number of factors, which may disrupt or completely block the smooth operation of a production processes. This paper seeks to address one of the key factors involved, machine failure, which is capable of introducing disorganisation and nervousness into production. The relevance of machine failure to production is highlighted by the extensive research in the field of robust scheduling, as a method to absorb potential disruptions. The aim of this paper is to present technological machine failure prediction method to provide the base for a robust schedule, which is subsequently verified by the mathematical model. Furthermore, the paper elaborates on the issue of scheduling in job shop environment and the idea of robust scheduling.

Keywords: Machine failure, prediction, robust scheduling, job shop scheduling, operational management.
