Different terminologies for the same research object may arise in different research communities. By this inconsistency, many synergistic effects get lost. Theories and models will be more understandable and reusable if a common terminology is applied. This paper examines the terminological (in)consistence for the research field of job-shop scheduling by a literature review. There is an enormous variety in the choice of terms and mathematical notation for the same concept. The comparability, reusability and combinability of scheduling methods is unnecessarily hampered by the arbitrary use of homonyms and synonyms. The acceptance in the community of used variables and notation forms is shown by means of a compliance quotient. This is proven by the evaluation of 240 scientific publications on planning methods.}, language = {en} } @article{MuellerWeberGronau2006, author = {M{\"u}ller, C. and Weber, Edzard and Gronau, Norbert}, title = {Requirements for an integration of methods analyzing social issues in knowledge organizations}, year = {2006}, language = {en} } @incollection{GronauWeberWanderetal.2022, author = {Gronau, Norbert and Weber, Edzard and Wander, Paul and Ullrich, Andr{\´e}}, title = {A regional remanufacturing network approach}, series = {Digitization of the work environment for sustainable production}, booktitle = {Digitization of the work environment for sustainable production}, editor = {Plapper, Peter}, publisher = {GITO Verlag}, address = {Berlin}, isbn = {978-3-95545-407-4}, doi = {10.30844/WGAB_2022_8}, pages = {145 -- 170}, year = {2022}, abstract = {Manufacturing companies still have relatively few points of contact with the circular economy. Especially, extending life time of whole products or parts via remanufacturing is an promising approach to reduce waste. However, necessary cost-efficient assessment of the condition of the individual parts is challenging and assessment procedures are technically complex (e.g., scanning and testing procedures). Furthermore, these assessment procedures are usually only available after the disassembly process has been completed. This is where conceptualization, data acquisition and simulation of remanufacturing processes can help. One major constraining aspect of remanufacturing is reducing logistic efforts, since these also have negative external effects on the environment. Thus regionalization is an additional but in the end consequential challenge for remanufacturing. This article aims to fill a gap by providing an regional remanufacturing approach, in particular the design of local remanufacturing chains. Thereby, further focus lies on modeling and simulating alternative courses of action, including feasibility study and eco-nomic assessment.}, language = {en} } @article{GronauWeberUslar2005, author = {Gronau, Norbert and Weber, Edzard and Uslar, Mathias}, title = {Institutionalization of a general electronic democracy through electronic democratic parties : a general concept with focus on Germany}, year = {2005}, abstract = {Not only the public services are able to ensure the effective and efficient use of e-democracy tools.

These contents and voting results are implemented obligatorily in the parliament by the delegates of the party. The electronic democracy contributes, in order to supplement the representative democracy, scalable around direct democratic elements.
