4.2.2. When Trucks are Greater Than the Balanced Number

Try these first

1. 1.

   What is the balanced number of trucks for efficient operation?

   Hint

   Think about the idea of balance in operations.

2. 2.

   Define gravimetric capacity.

   Hint

   Consider the manufacturer's specification.

3. 3.

   What is the effect of having too many trucks compared to the balanced number?

   • Increased productivity
   • Idle trucks
   • Lower maintenance costs

   Hint

   Think about what happens when you overload a system.

4. 4.

   Is it true that gravimetric capacity must be checked for every load?

   • True
   • False

   Hint

   Consider the manufacturer's ratings.

5. 5.

   A project manager finds that increasing the number of trucks from 7 to 9 has limited impact due to high idle times. Calculate the overall productivity effect if the expected output without congestion is 150 m³ per hour.

   Hint

   Think about the effects of adding too many resources without efficiency.

6. 6.

   You have two scenarios: Scenario A with 6 trucks at full load versus Scenario B with 8 trucks but short loads. Calculate which scenario is more productive and the cost implications for maintenance and time delays.

   Hint

   Breakdown the production numbers to see which has a net gain.
