Flexibility chart 2.0: An accessible visual tool to evaluate flexibility resources in power systems

Flexibility in 21st Century Power Systems

All power systems have some inherent level of flexibility— designed to balance supply and demand at all times. Variability and uncertainty are not new to power systems because loads change over time and in sometimes unpredictable ways, and conventional resources fail unexpectedly. Variable renewable energy supply, however, can make this balance harder to achieve. Both wind and solar generation ...

Application of queuing theory in inventory systems with substitution flexibility

Considering the competition in today’s business environment, tactical planning of a supply chain becomes more complex than before. In many multi-product inventory systems, substitution flexibility can improve profits. This paper aims to prepare a comprehensive substitution inventory model, where an inventory system with two substitute products with ignorable lead time has been considered, and e...

An Examination of Information Systems Flexibility

This study explores the possibility of flexibility in the use of information technology. The study examines different viewpoints and definitions of flexibility and tries to reconcile some of these different viewpoints by creating a model for flexibility in information systems. The model addresses two different types of flexibility, efficient versatility and robust responsiveness, that might eff...
