Fleet vehicle assignment calculator

Calculate assignments [job,vehicle,mass utilization %,volume utilization %] and unserved job IDs with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use assignments [job,vehicle,mass utilization %,volume utilization %] and unserved job IDs to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Assignments [job,vehicle,mass utilization %,volume utilization %]

Process jobs by fixed start then ID; choose smallest mass capacity then volume then ID among compatible available vehicles, respecting both capacities and no overlapping assigned jobs.

Unserved job IDs

Jobs with no feasible vehicle under greedy schedule.

Assigned job count

Count job-to-vehicle assignments.

Symbols and units
a
Jobs JSON [ID,start min,end min,required mass kg,required volume m³,compatible type IDs]
b
Vehicles JSON [ID,usable mass kg,usable volume m³,type ID,available start,end]

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

  • Fixed job windows already include travel, loading and turnaround. Compatibility and usable capacities entirely supplied. Greedy assignment is feasible under stated constraints but not optimal routing or legal loading approval. Supported limits: 1..100 jobs/vehicles; unique IDs; capacities>0; nonnegative demands; integer 0<=start<end<=10080; known type strings.
