Resource-Constrained Scheduling Exercise

Project Management Larson/Gray, Ch. 8, Exercise 4

You have prepared the following schedule for a project in which the key resource is a tractor(s). There are three tractors available to the project. Activities A and D require one tractor to complete while activities B, C, E, and F require 2 tractors.

Develop a resource-constrained schedule in the loading chart that follows. Use the parallel method and heuristics (rules) given. Be sure to update each period as the computer would do. Record the early start (ES), late finish (LF), and slack (SL) for the new schedule.
