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} } @article{TerbrackFrankHerrmannetal., author = {Terbrack, Hajo and Frank, Ingo and Herrmann, Frank and Claus, Thorsten and Trost, Marco and G{\"o}tz, Matthias}, title = {A literature database on ecological sustainability in hierarchical production planning}, series = {Anwendungen und Konzepte der Wirtschaftsinformatik}, journal = {Anwendungen und Konzepte der Wirtschaftsinformatik}, number = {12}, publisher = {AKWI}, issn = {2296-4592}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:898-opus4-23539}, pages = {36 -- 40}, abstract = {This article describes a systematic literature search of research articles on the topics of ecological sustainability and production planning.

Associated with this, the consideration of energy-related emissions is becoming an additional point of interest for decisionmakers in both, economic and ecological terms. Based on an extensive systematic literature review, the study at hand presents a multicriterial scheduling problem that addresses tardiness, energy consumption and energy-related emissions in production scheduling. A model is introduced that takes into account job release dates, multiple machine states, a power demand threshold as well as time-varying emission conversion factors. Multiple case studies are analysed and the effects of different technological implementations as energy onsite generation and energy storage systems are evaluated. Furthermore, several price mechanisms regarding energy procurement and emission trading are discussed. Moreover, by coupling the optimization model to a discrete event simulation model, we are able to compare the model results to real case scenarios. First computational experiments have demonstrated that the model and its extensions can effectively reduce the environmental impact associated with production while simultaneously considering corresponding economic objectives. Based on the proposed approach, our research aims on answering the question with which economic trade-offs an ecological improvement in terms of energy consumption and emission output can be achieved in production.}, language = {en} } @inproceedings{TrostForstnerClausetal., author = {Trost, Marco and Forstner, Robert and Claus, Thorsten and Herrmann, Frank and Frank, Ingo and Terbrack, Hajo}, title = {Sustainable Production Planning and Control: A Systematic Literature Review}, series = {Proceedings of the 33th European Conference on Modelling and Simulation 2019 (ECMS), Caserta, Italy}, volume = {33,1}, booktitle = {Proceedings of the 33th European Conference on Modelling and Simulation 2019 (ECMS), Caserta, Italy}, doi = {10.7148/2019}, pages = {303 -- 309}, abstract = {This article reviews the state of the art in research regarding sustainable extensions of hierarchical production planning.

Thus, it might be highly relevant to improve sustainability. In the literature mainly the scheduling level as well as the ecological dimension are considered.

With the paper at hand, we review the literature on energy-oriented production planning. The aim of this study is to derive similar core issues and related properties along energy-oriented models within hierarchical production planning. For this, we carry out a systematic literature review and analyze and synthesize 375 research articles.

This paper demonstrates that besides these classical models, a variety of approaches exist to influence ecological and social targets through production planning. These different models are assigned to sustainability areas and outlined by exemplary literature sources.
