Example

Determine the break$-$even haul time between a direct haul truck system and a transfer station operation with the following properties:

Direct haul system uses a $10y{d}^3$ container

Direct haul cost $=\frac{20}{h}r$

The transfer trailer has a capacity of $100y{d}^3$

Tractor$-$ trailer haul cost $=\frac{40}{h}r$

Function of amortized capital cost, capacity, operating costs

Cost $3,750,000($for building, equipment, tractor$/$trailer$)$

Capacity of $300,000y{d}^3$ per year

CRF is $0\mathrm{.}08($capital recovery factor is a function of interest rate and years to pay off $-$ converts capital cost to $\frac{}{y}r),y{r}^{-1}$

TS operating cost is $225,\frac{000}{y}r$
