1.3. Comparison of Productivity for 5 and 6 Scrapers

Try these first

1. 1.

   What is the production rate for 5 scrapers?

   Hint

   Refer back to the production calculations in the section.

2. 2.

   What is the unit cost of production for 6 scrapers?

   Hint

   Check the section for calculations of production costs.

3. 3.

   What is the primary control mechanism when using 5 scrapers?

   • Pusher
   • Scraper
   • Both Equal

   Hint

   Think about equipment dependency in a limited resource scenario.

4. 4.

   Using 6 scrapers results in higher productivity. True or False?

   • True
   • False

   Hint

   Reflect on the production outputs discussed in the section.

5. 5.

   If a construction project requires a minimum of 700 bank cubic meters per hour, which configuration should you use? Justify your choice with calculations.

   Hint

   Focus on productivity outputs.

6. 6.

   Analyze how increasing costs across all scrapers would influence the operational budget of using 5 versus 6 scrapers in a project for 120 hours of operation.

   Hint

   Look not only at production but total operational effectiveness.
