Figure 4. shows the evolution of the system when the resource R2 is also endowed with the competence C1 with efficiency 0.8. Compared with the previous case, now the price range is lower for resource R1 and higher for R2. Although the duration of task T22 of project P2 is smaller in resource R1 than in R2, now the system have to reallocate in real-time this activity to R2. So, R1 can perform in time the task T51 of the project P5. In this experiment, the project P5 is accepted and executed, and the total value has been increased from 55700 to 69369. This shows that the system is capable to use the flexibility of resource R2 to improve in real-time the global performance.
