Calculation method
Calculation method
Feasible precedence schedule (JSON)
Repeatedly choose earliest-start ready task and earliest-free worker; tie by task index then worker. Tasks are nonpreemptive.
Completion time (minute)
Maximum scheduled task end.
Deadline overrun (minutes)
max(0,completion−deadline).
Symbols and units
- a
- Photography tasks [minutes,zero-based predecessors]; enter JSON
- b
- Available interchangeable workers (count)
- c
- Earliest start (minute)
- d
- Required completion deadline (minute)
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
- Photography setup, travel, sessions and editing are explicit predecessor tasks; one or more interchangeable workers, without animal-behavior assumptions. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. 1..100 tasks; positive durations; predecessor indices exist and graph is acyclic; workers 1..20. Interchangeable workers; no specialist equipment constraints unless encoded as dependencies.
