1.2. Economics of Different Truck Numbers

Try these first

1. 1.

   What is a balance number in trucking?

   Hint

   Think about how many trucks can operate without waiting.

2. 2.

   Calculate the total cost for 6 trucks at 1650 rupees per hour.

   Hint

   Multiply the number of trucks by the cost per truck and add loader cost.

3. 3.

   What is the balance number of trucks for one loader?

   • 5
   • 7
   • 9
   • 0

   Hint

   Refer back to the cycle time calculations.

4. 4.

   True or False: Increasing the number of trucks beyond the balance number lowers unit production costs.

   • True
   • False

   Hint

   Think about what happens when the trucks sit idle.

5. 5.

   Analyze a scenario where 10 trucks are used instead of the calculated balance number. Discuss the implications on costs, productivity, and potential operational inefficiencies.

   Hint

   Consider how many trucks are realistically able to load while factoring in waiting times.

6. 6.

   If the loader's productivity is increased to 100 cubic meters per hour, recalibrate the balance number of trucks needed to optimize productivity.

   Hint

   Look back at how truck and loader cycle times influence the balance number.
