(d) Gradability and traction
(e) Ancillary equipment
(a) Equipment life
Economic life - Period over which an asset (machine, property, computer system, etc) is expected to be usable.
(b) Life-cycle costing
6.4.2 VEHICLE COSTS
Basic concept of life-cycle costing
Total unit costs are affected by each of the following:
(b) Operations – rises gradually with fuel and tolls.
(d) Downtime – vehicle not available for service
(e) Obsolescence – obsolete - can’t do the job
(f) Inventory costs – supports the repair function
(g) Life costs – sum of fixed and variable costs
