1.3. Job Production Estimation

Try these first

1. 1.

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

   Hint

   Use the formula: Balance Number = Truck Cycle Time / Loader Cycle Time.

2. 2.

   State the formula for calculating unit production cost.

   Hint

   What are the two components needed for this calculation?

3. 3.

   What is the optimal balance number of trucks calculated in this section?

   • 5
   • 7
   • 9

   Hint

   Remember the formula used for calculating balance number.

4. 4.

   Is increasing the number of trucks beyond the balance number advisable?

   • True
   • False

   Hint

   Think about the relationship between trucks and loader productivity.

5. 5.

   Your team is tasked with managing the loading operations with varying numbers of trucks. If you have estimates for costs and productivities, how would you approach determining the ideal number of trucks without risking overcapacity?

   Hint

   Use the formulas discussed in class to guide your calculations.

6. 6.

   Critically evaluate a scenario where multiple teams are recommending different numbers of trucks (5, 8, and 9). How will you substantiate your recommendation using the concepts learned?

   Hint

   Focus on the economic aspects and how they translate to operational efficiency.
