 Redundancy based methods are proactive scheduling methods for solving 
 the Project
 </p>
 <p>
 Scheduling Problem (PSP) with non-deterministic activities duration. The 
 fundamental
 </p>
 <p>
 strategy of these methods is to estimate the activities duration by 
 adding extra time to the
 </p>
 <p>
 original duration. The extra time allows to consider the risks that may 
 affect the activities
 </p>
 <p>
 durations and to reduce the number of adjustments to the baseline 
 generated for the project.
 </p>
 <p>
 In this article, four methods based on redundancies were proposed and 
 compared from two
 </p>
 <p>
 robustness indicators. These indicators were calculated after running a 
 simulation process.
 </p>
 <p>
 On the other hand, linear programming was applied as the solution 
 technique to generate
 </p>
 <p>
 the baselines of 480 projects analyzed. Finally, the results obtained 
 allowed to identify the
 </p>
 <p>
 most adequate method to solve the PSP with probabilistic activity 
 duration and generate
 </p>
 <p>
 robust baselines.
