In practice
Example: a two-pallet collection
A vehicle with capacity for four pallets starts empty. The job adds two pallets at a depot and removes those two pallets at the customer site.
This ledger explains capacity arithmetic for one fictional job. It is not a calculated plan. When other jobs share the route, their load changes and visit windows also affect the plan. For multiple capacity dimensions, each relevant quantity needs consistent units and limits.
Stop: Start; Load change: 0; On-board pallets after this stop: 0
Stop: Pickup; Load change: +2; On-board pallets after this stop: 2
Stop: Delivery; Load change: -2; On-board pallets after this stop: 0
