Event series Production systems - analyse and design

The Institute for Production Systems (IPS) at the Technical University of Dortmund invited all interested companies to an exciting workshop on the subject of production systems analysis and design on 28 June 2019

Based on the previous successes of the event series, the IPS invited all interested companies to present and discuss the latest research results. The main focus was on the topics "adherence to delivery dates in special machine construction" and "machine occupancy planning in multi-variant production systems".

The event started with an interactive workshop in which the companies worked out and presented the challenges of meeting delivery deadlines and target lead times on the basis of their experience. With a total of 10 companies and 15 participants, an extensive portfolio of potential challenges was developed and it was not uncommon to find that despite different industries and products, the challenges are often the same.

After the workshop Thomas Henke from IPS presented the research results of the SySMaG research project. The aim of the project, which ended on 30.06.2019, was to develop a planning system for standardized material provision in the complex, multi-variant assembly of large equipment with small quantities. The developed planning system provides for two successive optimization models: in the first step, the assembly sequence required to meet the delivery date is identified before it is converted into a throughput time optimized material provision plan with the help of the second optimization model.

In the second part of the workshop, Patrick Wolf described the results of the VariPro research project. It addresses the problem of variability in customer-specific production. The focus is on the connection to the topic of machine allocation planning in order to enable variability-based machine allocation planning. First, the subdivision into value-adding and non-value-adding variability was presented as a basis. Non-value-adding variability is variability that should be eliminated as well as variability that cannot be eliminated completely. In contrast, value-adding variability should not be directly reduced, since it leads to an increase in customer benefit and thus contributes to value creation. On this basis, 14 variability criteria were defined, which should be taken into account when planning machine occupancy. In addition to these criteria, a mathematical optimization model was presented which, in conjunction with the variability criteria, will be transferred to an IT tool during the remaining project period.

The event was concluded with a lecture by Frederik Ostermeier from BMW AG, who presented a concept for efficient line control in the context of high variability.
