Calculation method
Calculation method
Drum assignment per run (JSON)
First-fit whole-run cuts in supplied order including one entered allowance per run; failure means this heuristic cannot allocate, not proof of global infeasibility.
Remaining lengths by drum (JSON)
First-fit whole-run cuts in supplied order including one entered allowance per run; failure means this heuristic cannot allocate, not proof of global infeasibility.
Symbols and units
- a
- Cable run cut lengths (m)
- b
- Available drum lengths (m)
- c
- End allowance per run (m)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; First-fit whole-run cuts in supplied order including one entered allowance per run; failure means this heuristic cannot allocate, not proof of global infeasibility. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
