What it is Filled
A process that repeats through a sequence of states or stages returning to its starting condition, such as astronomical cycles, glacial cycles, freeze-thaw cycles, biological and biochemical cycles, engine operating cycles, data and product lifecycles and research cycles; cyclic processes are described by period, phases and drivers, modelled in science and engineering, and used to structure work and management.
Why it exists Filled
Let an agent explain cyclic processes and their characteristics, identify cycles in nature, technology and organisations, describe modelling of cycles, and support learning.
Distinguishing features Filled
- Repetition
- Phases
- Period
- Cross-domain
What robots and AI may and may not do Filled
Must not
- Present a cycle as perfectly periodic when the data show variation.
- Claim cyclic causation from correlation alone.
- Keep a component in service past its rated cycle count.
Only with a human decision
- Retiring or extending the life of a part based on its cycle history.
May
- Model and report cyclic processes, stating period, phase and uncertainty.
- Count load cycles on components it monitors and report fatigue limits.
Moral aspects Filled
- Fatigue from repeated cycles causes sudden structural failures that hurt people.
- Forecasts from assumed cycles can mislead decisions about economies and climate.
Who is affected
- Users of machines and structures
- Forecast users
- Students
Owners Filled
Steward
Nobody owns the concept; the owner of each system answers for its cycles.
