2.2. Unit Cost Calculation Process

Try these first

1. 1.

   What is the truck cycle time as mentioned in the section?

   Hint

   It's a key value mentioned for productivity calculations.

2. 2.

   If one truck operates at 12.53 cubic meters per hour, what is the productivity with 5 trucks?

   Hint

   Multiply the individual truck productivity by the number of trucks.

3. 3.

   What is the truck cycle time provided in the section?

   • 35.5 seconds
   • 39.5 seconds
   • 42.5 seconds

   Hint

   Remember the exact figures provided earlier.

4. 4.

   True or False: The productivity cannot exceed the loader's capacity beyond the balance number.

   • True
   • False

   Hint

   Consider the influence of one loader with multiple trucks.

5. 5.

   You are planning a site with 11 trucks but only 1 loader. Calculate potential productivity and unit cost, highlighting inefficiencies.

   Hint

   Consider the scenario against balance number principles.

6. 6.

   Create a detailed breakdown of how many trucks you would recommend for a new project starting with 10 trucks. Justify your recommendation with calculations.

   Hint

   Start with the current productivity vs. balance considerations for both.
