From the standpoint of real-world scheduling problem, it is necessary to find solution of building the schedule which can be insensitive to production disruptions such as machine breakdowns, incorrectly estimated time interval of machines maintenance, absence of workers, unavailability of materials or tooling, production defects, variable processing times, etc. This research study is conducted to answer the question: how the researchers cope with the problem of production uncertainty taking into account the scheduling problem? Our investigation focuses on approaches developed for scheduling with production uncertainty consideration. Among these approaches the most popular ones are: reactive scheduling, proactive scheduling, predictive scheduling and robust predictive-reactive approaches. A brief explanation of individual approaches are presented. Further, models of uncertainty used in scheduling ...

The description is restricted to the class of the systems called electronic andon system. The way of gathering data from manufacturing cell about process performance is depicted. Integration of electronic andon with ERP systems is presented.

It mainly refers to the applied metaheuristic techniques which have been exploited in this research area. A comparison of presented approaches is attempted, some concluding insights are highlighted. Finally future research directions are suggested.
