criticalpath: Critical Path Method R Implementation

Description

criticalpath package is an R implementation of the Critical Path Method (CPM). CPM is a method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model. The flexibility is in terms of early start, early finish, late start, late finish, total float and free float. Beside, it permits to quantify the complexity of network diagram through the analysis of topological indicators. Finally, it permits to change the activities duration to perform what-if scenario analysis.

Details

With this package, you can calculate the following CPM parameters:

• Schedule duration

• Early start and finish date of each activity

• Late start and finish date of each activity

• Critical activities

• Critical path

• Total float and free float

• Gantt Matrix

• What-if scenario analysis

• Topological indicators
