MTBF evaluation for 2-out-of-3 redundant repairable systems with common cause and cascade failures considering fuzzy rates for failures and repair: A case study of a centrifugal water pumping system
Mortazavi, Seyed Mohammad; Mohamadi, Maryam; Jouzdani, Javid - In: Journal of Industrial Engineering International 14 (2018) 2, pp. 281-291
In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible...

European power struggles: Can EU's decarbonisation agenda break the state-company axis in the power sector?
Sattich, Thomas; Ydersbond, Inga; Scholten, Daniel - 2015
Europe's power system is still marked by a distinct national component, and despite some regions with strongly integrated power systems, electricity supply today still has a largely national basis. Policies to decarbonise the power sector may fundamentally alter this situation, because power...

Electricity storage and transmission: Complements or substitutes?
Neetzow, Paul; Pechan, Anna; Eisenack, Klaus - 2018
Electricity from renewable sources often cannot be generated when and where it is needed. To deal with these temporal and spatial discrepancies, one frequently proposed approach is to expand storage capacities and transmission grids. It is often argued that the two technologies substitute each...

Super-grids and concentrated solar power: A scenario analysis with the WITCH model
Massetti, Emanuele; Ricci, Elena Claire - 2011
We extend the WITCH model to consider the possibility to produce and trade electricity generated by large scale concentrated solar power plants in highly productive areas that are connected to the demand centres through High Voltage Direct Current (HVDC) cables. We find that it becomes optimal...

How to Escape from Model Platonism in Economics: Critical Assumptions, Robust Conclusions, and Approximate Explanations
Albert, Max - In: Homo Oeconomicus 39 (2022) 1, pp. 37-68
About sixty years ago, Hans Albert criticized economists for their "model platonism", a methodological attitude that immunizes theoretical models against empirical criticism. Since then, economics has taken an empirical turn; yet, model platonism lingers on. The root of the problem is...

On reliability of reinforcement learning based production scheduling systems: a comparative survey
Waubert de Puiseau, Constantin; Meyes, Richard; Meisen, … - In: Journal of Intelligent Manufacturing 33 (2022) 4, pp. 911-927
The deep reinforcement learning (DRL) community has published remarkable results on complex strategic planning problems, most famously in virtual scenarios for board and video games. However, the application to real-world scenarios such as production scheduling (PS) problems remains a challenge...
