Challenge Problems

Push your limits with challenges.

Question 1

A construction site planning team needs to decide between using back-track loading and chain loading. Back-track loading takes 20 minutes per cycle, while chain loading takes 15 minutes. If the project manager wants to optimize productivity, how many more cycles can they perform using chain loading in a 4-hour work period compared to back-track loading?

💡 Hint: Calculate the number of cycles for each method using the total time available.

Question 2

If a pusher has a cycle time of 25 minutes and it is found that increasing the number of scrapers from 3 to 5 reduces the cycle time by 5 minutes due to efficiency improvements, how many scrapers can the pusher effectively serve?

💡 Hint: Examine how increasing the number of scrapers affects overall efficiency.
