Tokarczyk J.

S u m m a r y
Part of an extensive problem which is virtual prototy ping of technical means was discussed in the paper. Official definition of virtual prototyping was given. The objective of creation of physical prototypes (FP) and difficulties associated with its construction were presented, especially those of mining machines. Physical and virtual prototyping were compared. Scope of use and limitations of both methods were discussed.
