Question 3 The management of the Department of Public Works of Puerto Rico has developed a simulation of an entrance ramp to PR-22 express, which controls the access by changing the traffic light timing. Playing with a simulation software has resulted in approximate system values that are like those observed while changing some parameters of the system. This behavior demonstrates that: The simulation offers valid results. The simulation results cannot be trusted. A new simulation would be required to malce accurate decisions. The managers lack the necessary computer skills to run the simulation Question 4 How can we cope with the lack of flexibility provided by non playing systems? Develop a simulation program to play with it. Play with them anyway. Guess what would happen whenever some action is taken Avoid playing with the system
