Sustainability is currently of considerable importance due to various interest groups. Hierarchical operational production planning and control is the state of the art in research as well as in industrial practice for planning of stations and their aggregations to production systems. Thus, it might be highly relevant to improve sustainability. In the literature mainly the scheduling level as well as the ecological dimension are considered. So the current research is limited to selected partial planning problems and incomplete with regard to sustainable aspects that emerge.}, subject = {Produktionsplanung}, language = {en} } @inproceedings{FrankHerrmannClaus, author = {Frank, Ingo and Herrmann, Frank and Claus, Thorsten}, title = {Improving sustainability through substitutes in cross-location production planning}, series = {Proceedings of the International Annual Conference of the German Operations Research Society 2019 (OR 2019), Dresden, September 3 - 6, 2019}, booktitle = {Proceedings of the International Annual Conference of the German Operations Research Society 2019 (OR 2019), Dresden, September 3 - 6, 2019}, subject = {Produktionsplanung}, language = {en} } @incollection{TerbrackFrankHerrmannetal., author = {Terbrack, Hajo and Frank, Ingo and Herrmann, Frank and Claus, Thorsten and Trost, Marco}, title = {Eine Literaturdatenbank zur Nachhaltigkeit in der hierarchischen Produktionsplanung}, series = {Produktionsplanung und -steuerung}, booktitle = {Produktionsplanung und -steuerung}, editor = {Claus, Thorsten and Herrmann, Frank and Manitz, Michael}, publisher = {Springer Gabler}, address = {Berlin, Heidelberg}, isbn = {978-3-662-64290-0}, doi = {10.1007/978-3-662-64291-7_3}, pages = {27 -- 35}, language = {de} } @inproceedings{TrostClausHerrmann, author = {Trost, Marco and Claus, Thorsten and Herrmann, Frank}, title = {Employment of temporary workers and use of overtime to achieve volume flexibility using master production scheduling: monetary and social implications}, series = {Proceedings of the 35th ECMS International Conference on Modelling and Simulation (ECMS 2021): May 31st-June 2nd, 2021, United Kingdom}, booktitle = {Proceedings of the 35th ECMS International Conference on Modelling and Simulation (ECMS 2021): May 31st-June 2nd, 2021, United Kingdom}, editor = {Al-Begain, Khalid}, isbn = {978-3-937436-72-2}, doi = {10.7148/2021-0213}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-24906}, abstract = {Flexibility and in particular volume flexibility is an important topic for industrial manufacturing companies. In this context, the harmonization of the available and required capacity is a central task, especially with increasing fluctuations in customer demand. In classical approaches , this is considered only by the use of additional capacities and there are only a few approaches that combine aspects of personnel planning with production planning. Therefore, this article presents a linear optimization model for master production scheduling that includes aspects of personnel requirements planning. It is used to investigate different strategies for the use of overtime and temporary workers in order to achieve different levels of volume flexibility. With regard to the monetary and social impacts, the results indicate that overtime has a stronger influence to achieve volume flexibility than the use of temporary workers. However, both are affected by substantial deficits in human working conditions. But the results also imply a promising potential for improving the social aspects without a significant increase in costs.}, language = {en} } @inproceedings{TrostClausHerrmann, author = {Trost, Marco and Claus, Thorsten and Herrmann, Frank}, title = {Influence of Company Sizes in adapted Master Production Scheduling for Improving Human Working Conditions}, series = {Proceedings of the 34th International ECMS Conference on Modelling and Simulation, ECMS 2020}, booktitle = {Proceedings of the 34th International ECMS Conference on Modelling and Simulation, ECMS 2020}, editor = {Steglich, Mike}, publisher = {European Council for Modelling and Simulation}, isbn = {978-3-937436-68-5}, doi = {10.7148/2020-0287}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-24817}, pages = {287 -- 293}, abstract = {Sustainability is an important topic in production plan-ning and control.

Further-more, this article analyses the influence of the compa-ny size on workload and costs using an application with a high proportion of manual activities. It is demonstrat-ed that human working conditions can be improved independently from the company size without increas-ing costs. In addition, smaller companies tend to have a higher exhaustion and the workload affects the total costs more in smaller companies. Therefore, smaller companies might benefit more from an improvement in human working conditions.}, language = {en} } @inproceedings{TerbrackHerrmannClaus, author = {Terbrack, Hajo and Herrmann, Frank and Claus, Thorsten}, title = {Deviation in Energy Consumption on Aggregate Production Planning Level in Industry Practice}, series = {Proceedings of the 34th International ECMS Conference on Modelling and Simulation (ECMS 2020)}, booktitle = {Proceedings of the 34th International ECMS Conference on Modelling and Simulation (ECMS 2020)}, editor = {Steglich, Mike}, isbn = {978-3-937436-68-5}, doi = {10.7148/2020-0334}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-24804}, pages = {334 -- 340}, abstract = {In this article, we discuss energy consumption of producing firms on aggregate production planning. While almost constant energy consumption can be the case for a producing firm, highly fluctuating energy demand can occur as well. Together with volatile energy supply, e.g. due to renewable energy sources, this combination of fluctuating energy supply and demand can result in planning uncertainty and high energy costs. We propose different case studies in which such high deviation in the electricity consumption of a producing firm occurs due to aggregate production planning without appropriate consideration of energy consumption.}, language = {en} } @inproceedings{Herrmann, author = {Herrmann, Frank}, title = {The Use of Simulation for Manufacturing Applications}, series = {Proceedings of the 12th International Conference on Advances in System Simulation, SIMUL 2020, 18.-22.10.2020 in Porto, Portugal}, booktitle = {Proceedings of the 12th International Conference on Advances in System Simulation, SIMUL 2020, 18.-22.10.2020 in Porto, Portugal}, publisher = {IARIA XPS Press}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-24899}, abstract = {This paper summarizes six presentations in a session of the track "Use of Simulation for Manufacturing Applications".
