Best of Planning – Combining Global Optimization and Local Reactivity

Thursday 3rd December 15:00 - 15:30

For a long time, the production process and production chain complexities as well as the large batch sizes of aluminium production have required different time horizons and level of details for planning activities. Long, medium- and short-term planning and scheduling form the basis to produce the right products on time and achieve an optimal utilization of expensive machines and semi-finished goods inventories. As the algorithms and computational support are getting more and more sophisticated and detailed, nearly optimal plans across multiple lines have become a standard. But planning in aluminium production still faces challenges:

• Deviations are common during production, yet changes to plans and schedules are difficult and time consuming, leading to significant reaction delays

• Data inputs have to be synthesized to come to an appropriate decision how to act – a still mostly manual task

• Optimized production plans and schedules are more sensitive to production constraints leaving less room for deviation

Today’s planning and scheduling algorithms are designed from a “global or federal” point of view. Most planning and scheduling decisions are made by a central planning department; decisions are implemented top-down. Here the so-called software agents, small pieces of software, come in and focus on a very specific set of problems. They address a problem by automatically responding to a wide variety of data sources enabling independent, local decisions to be made quickly and flexibly. This purely local approach, however, misses the optimization of a global planning and scheduling approach.

In this paper, PSI introduces a concept of how the well-known “top-down” planning approaches can be combined with more “bottom-up” local software agents to create a reactive yet highly optimized planning solution. With that we show you, how to combine the technology of multi-agent systems to benefit from new capabilities of digitalization. Further, an I4.0 architecture (the PSImetals Service Platform) will be introduced that covers all important aspects required by our“ best of both worlds” approach to achieve the “Best of Planning” - combining global optimization and local reactivity.

Best of Planning – Combining Global Optimization and Local Reactivity

Gunther Schober, born November 21, 1970 in Leoben, Austria graduated in 1994 as Metallurgical Engineer with focus on industrial and energy economics at the Mining University of Leoben.

After his first experience as sales engineer and sales manager he took over management responsibility as head of sales & marketing for AVL DiTEST an international automotive company. 2007 he joined PSI Metals. As Senior Consultant, Project Manager and Sales Manager his expertise in metals and international experience in process development and Supply Chain Management is much sought-after.

With more than 10 years of experience in the area of Production Management Solutions comprising Supply Chain Management and Planning, Product Design, Quality Management, Production Execution and Logistics he became an acknowledged cognoscente in these fields. PSI Metals known as a very innovative company became metals industries’ partner for Industry 4.0.

Gunther Schober’s expertise together with the innovative approach of PSI metals make him a demanded contact for future solutions.
