Challenge Problems
Push your limits with advanced challenges
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.
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.
