Why use simulator to train the operators ??

Before actually operating what can cost allot, use a simulator to get satisfied wheather someone is ready to be given costly peice of machinery or not.

Dear Mr. Bader, Usually we use simulation to do practical trianing but under no risk or critical opertating conditions such as ovens operation or plastic injection machine any tri.al under no attention will lead to sever losses thus we use it on production machine. On other hand we use simulation to enhance unlimited numbers of trials in the field of control such plc programmable logic control and on this way

To be sure that they knowing how they have to run
