Invited Research Lecture on Vertical Data Integration for Reactive Production Scheduling

Date: 04 Jun 2008 - 04 Jun 2008

Venue: Auditorium, Level 3, Tower Block


This lecture presents some project activities in the area of reactive scheduling and control. Within a planning and scheduling environment e.g. in a production scenario it is not only important to have a good schedule for the planned activities but also necessary to react to the events of the shop floor.

While production takes place several data is collected about the production itself but also several events occur that may affect the production and thus have to be treated by systems or personnel. Some of these events may even corrupt the whole schedule so that an immediate rescheduling is necessary. Within the project, the problems of reactive scheduling and control will be investigated.

First, the data collected will be categorised, and then the decision will be made as to the reaction towards the data and events. Some data will need no response, e.g. when a job is finished in time, other need reaction, e.g. machine breakdowns. If the events have effects on other parts of the scheduled production it is necessary to perform some kind of reactive scheduling. The lecture will present some of the useful approaches to categorize data, aggregate them and use them on higher levels of scheduling and control.

About the Speaker

Dr Jürgen Sauer is an Associate Professor of Computer Science in the business informatics group, department of computer science, University of Oldenburg, Germany. He holds a Master of Science in computer science from the University of Dortmund and a PhD in computer science from the University of Oldenburg. Until 2003, he had been working as a senior research assistant in the information systems area in the software engineering lab of the department of computer science. From 2003 to 2006, he was the Head of the Computer Centre of the University of Oldenburg. His research focuses on intelligent systems in logistics especially in the area of scheduling and the management of complex and large application systems (adaptive computing). It covers modelling and solving scheduling problems mainly by using artificial intelligence approaches. His teaching activities focus on modeling, systems management, software engineering and intelligent systems, especially knowledge-based scheduling.

Dr Sauer is the speaker of the special interest group in planning, scheduling and configuration within the Artificial Intelligence Section of the German Computer Society and has organized several workshops on planning, scheduling and configuration. He is a member of the special interest group in manufacturing (SIGMAN) of the AAAI (Association for the Advancement of Artificial Intelligence).

Through several projects, scheduling systems have been developed for different application areas, for example for the chemical industry, the fittings industry, and hospitals. Some work has been done in cooperation with the Center for Integrated Manufacturing Decision Systems in the Robotics Institute of the Carnegie Mellon University, USA. His extensive project experiences cover several areas ranging from interoperability (EU-Chinese project STASIS) to planning problems in the local tree-nursery industry and scheduling regarding energy efficiency issues.
