- KonferenzbeitragElectricity Associations as Marked-based Steering Mechanism and Alternative to Fixed Feed-in Tariffs(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Meyer, Sören Christian; Breitner, Michael HansThis paper describes a business model for local electricity supply and demand steering using flexible electricity prices. Therefore it evaluates first the composition of the electricity price. Secondly it estimates the future renewable electricity generation cost. Therefore future renewable electricity generation prime cost are calculated with a combination of historically derived learning rates and global market growth estimations, both derived from literature. Thirdly it evaluates the tax burden on local traded electricity. As result a business model and legal construct which reduces the tax and levy burden on electricity is identified as crucial factor for flexible electricity prices. With electricity associations this paper identifies such a judicial construct. Finally centralised demand steering with smart flexible agents like electric vehicles, dishwasher and washer-dryer is described. This steering allows to synchronize renewable electricity generation from photovoltaic power plants, wind turbines and combined heat and power and the local electricity demand.
- KonferenzbeitragOptimal IT Project Selection – Quantification of Critical Scoring Criteria(Projektmanagement und Vorgehensmodelle 2022 - Virtuelle Zusammenarbeit und verlorene Kulturen?, 2022) Karrenbauer, Christin; Breitner, Michael HansThe management of IT project portfolios is challenging because of IT projects’ complexity, dynamics, unknowns, and uncertainties. IT projects account for a large IT budget proportion and significantly influence value contribution, strategic development, goal achievements, and competitive advantages. Many IT projects still fail, exceed time and resources, and do not reach their planned goals because of wrong decisions, unsatisfactory evaluation, and missing selection criteria. Thus, a continuous IT project scoring and selection is crucial to enable an optimal portfolio composition. We conduct a systematic literature review and 14 semi-structured qualitative expert interviews to develop a uniform and holistic scoring approach. Our findings show that IT projects’ urgency, strategy, efficiency, risk, and complexity are critical IT project scoring criteria. Our scoring approach increases objectivity and quality in evaluating planned and running IT projects and allows more convincing and transparent decisions.
