1.2. Productivity Estimation

Try these first

1. 1.

   What is the production formula for scrapers?

   Hint

   Remember the key components of efficiency.

2. 2.

   What happens when you use fewer scrapers than the balanced number?

   Hint

   Think about the implications for pushers.

3. 3.

   What is the ideal production strategy when using scrapers and pushers?

   • Fewer scrapers than needed
   • Balanced number of scrapers
   • Exceeding the number of scrapers

   Hint

   Consider the productivity impacts.

4. 4.

   True or False: A pusher controls production when there are more scrapers than the balanced number.

   • True
   • False

   Hint

   Think about the roles of different machines.

5. 5.

   Given that you have 4 scrapers producing 500 bcm/hr and you decide to add another which increases the total to 650 bcm/hr, calculate the increase in overall productivity per scraper.

   Hint

   Calculate the difference in productivity when adding the additional scraper.

6. 6.

   If using scrapers increases costs by ₹500 but the productivity raises by 100 bcm/hr, is it worth it based on production cost?

   Hint

   Consider the relationship between costs and efficiencies to make a judgment.
