Schedule the project described in the following table, subject to a resource constraint of 16 men. Any man can work on any task. For a given job, any crew size within, and including, the stated limits may be selected, if it is exactly divisible into the resource requirement. ( For example, job b requires 24 mandays. A crew size of 2, 3, 4, or 6 is permissable, but not 5 ). Crew sizes do not effect efficiency. The schedule length is to be minimized within the given resource LIMIT and keeping the technological constraints ( the ordering of Tasks) unaltered. Find the number of idle man-days.
