Challenge Problems

Push your limits with challenges.

Question 1

In a scenario where scrapers have varying loading times of 5, 7, and 6 minutes respectively, calculate the average pusher cycle time using the thumb rule formula. Discuss how variations in loading times might impact operational efficiency.

💡 Hint: Calculate each cycle time and average them to find the mean.

Question 2

Evaluate a construction site's efficiency if the pusher has 10 scrapers but can only realistically serve 4 due to its cycle time. Analyze possible alternatives to improve efficiency without increasing costs.

💡 Hint: Consider how aligning the number of scrapers with the pusher's capabilities can reduce waiting times.
