4. Summary and Conclusion

Try these first

1. 1.

   Calculate the productivity for 5 trucks if each can transport 12.53 cubic meters per hour.

   Hint

   Multiply the number of trucks by individual truck productivity.

2. 2.

   What is the balance number of trucks if the truck cycle time is 39.5 and loader cycle time is 5.5?

   Hint

   Use the formula: Truck cycle time divided by loader cycle time.

3. 3.

   What is the balance number of trucks for one loader?

   • 5
   • 6
   • 7.18
   • 8

   Hint

   Remember the calculation method!

4. 4.

   Exceeding the balance number increases unit production cost.

   • True
   • False

   Hint

   Think about how productivity caps when over balanced.

5. 5.

   Given the truck cycle time of 45 seconds and a loader cycle time of 6 seconds, calculate the new balance number of trucks and discuss its economic implications.

   Hint

   Apply the truck cycle over the loader cycle to get your base number.

6. 6.

   If the unit production cost increases when exceeding the balance number, how would you optimize truck and loader usage in a new project?

   Hint

   Consider both the operational rates of cost and productivity in your evaluations.
