2.3. Decision on Production Cost

Try these first

1. 1.

   What is the impact on production when using fewer scrapers than necessary?

   Hint

   Think about the relationship between the number of machines and production flow.

2. 2.

   If a pusher costs ₹5600 per hour, how much would five scrapers cost?

   Hint

   Remember to multiply the number of scrapers by their individual cost.

3. 3.

   What is the productivity when using five scrapers?

   • 636.89 bank cubic meters/hour
   • 723.36 bank cubic meters/hour
   • 500 bank cubic meters/hour

   Hint

   Check the calculations presented in the section.

4. 4.

   True or False: Increasing the number of scrapers always reduces production costs.

   • True
   • False

   Hint

   Remember the balance discussed in the section.

5. 5.

   A construction site uses a combination of scrapers and pushers. If the costs for the machinery are increased by 10%, how will this impact the unit production cost calculations?

   Hint

   Calculate the new hourly costs before recalculating the unit production cost.

6. 6.

   If the available scrapers at a site is cut down to three after a mechanical failure, how might this shift the operation and production rates?

   Hint

   Consider the implications of fewer machines impacting throughput.
