So far, literature on energy economics and engineering has provided analyses concerning various aspects of the system requirements for flexibility.
In particular, cotton blends with Spandex or Lycra were considered to be the best match with the design requirements for flexibility and movement because of their stretch and recovery properties.
Kjǽr and Madsen [15, p. 54] reinforced the importance of PD to specify the requirements for flexibility, saying that "… flexibility is not related to the regular procedure or behavior pattern of doing things, but the unexpected, unprecedented, exceptional cases, situations and events experienced only by those who perform the work daily".
So, although today's technical concepts for flexible BE allow for a good adaptation to the vRES feed-in patterns for 2022 in the TransnetBW TS, the limited overall amount of excess energy from renewables is indicating that there is little requirement for flexibility to avoid excess energy in the near-term.
Another tension to transpire in our data, which illuminates our understanding of facilitation in the PARiHS framework, was the requirement for flexibility within GM-HFIT at the same time as some degree of standardisation to ensure the work was completed.
This closely matches recent literature on analysis of postsimulation open-ended responses, which shows communication, leadership and teamwork as key themes, including "adaptability and requirement for flexibility in teamwork roles" and the "value of high-quality, clear communication"(ref. 35, p.205).
The mandates, furthermore, stipulate that the premises must satisfy necessary requirements for both flexibility and security.
Stringent requirements for performance, flexibility, dependability, and energy-efficiency in uncertain/dynamic environments have increased the demand for endowing systems with self-adaptation capabilities.
In case of large and complex industrial systems, such intimate link translates into the need to satisfy requirements for modularity, flexibility, and adaptability.
Modern software-intensive systems are becoming increasingly complex and the fulfillment of requirements for performance, flexibility, dependability, and energy-efficiency in uncertain and dynamic environments is still a quite challenging task (Huebscher and McCann 2008).
The major requirement is for flexibility to enable rapid changes of process parameters in order to develop new applications, with variations of materials and geometries in a cost effective and reliable manner.
