Question 15
Two beavers build a dam by completing eight tasks: A(2), B(3), C(5), D(7), E(10), F(9), G(4), H(6), where each number is the task’s duration in hours. Some tasks must wait for others, as the arrows show.
English diagram labels: Start and Finish mark the overall project. E waits for both A and B; H waits for E; F waits for C; G waits for D. Here is one schedule taking 32 hours:
The rows are Beaver 1 and Beaver 2; gray blocks are idle time. What is the shortest possible completion time?
