2.1. Cost Calculation for Different Combinations

Try these first

1. 1.

   What is the truck cycle time mentioned in the section?

   Hint

   Recall the specific figure given.

2. 2.

   At what productivity does one truck operate?

   Hint

   Look for the individual productivity rate mentioned.

3. 3.

   What is the approximate balance number of trucks calculated?

   • 5
   • 7
   • 8

   Hint

   Look for the rounded value derived from truck and loader cycle times.

4. 4.

   True or False: Increasing trucks beyond the balance number increases total productivity.

   • True
   • False

   Hint

   Consider the role of the loader in the productivity equation.

5. 5.

   If the loader's productivity rises to 100 cubic meters per hour, determine how this affects the balance number and the optimal number of trucks required.

   Hint

   Try recalculating using the new cycle times.

6. 6.

   For a construction site operation with a fixed budget, suggest the optimal number of trucks if maintaining a production cost below 170 rupees per cubic meter is crucial.

   Hint

   Calculate each iteration to stay under the budget.
