Streszczenie / Summary:

This paper presents results of research in time consumption of actual and virtual assembly of
a bus air-conditioner compressor using an MTM analysis of basic motions. Definitions of work
time, time consumption and work consumption are compared as they are often used interchangeably
in the literature. The article substantiates the subject and discusses the essence and objectives
of research in time consumed by assembly processes. It also presents characteristics of the MTM
methodology of analysis of basic motions, and steps required within its framework in order to
determine time consumption. The article also discusses EON ICATCHER, a passive, multidisplay,
3D projection system, basic software and stages of determining time consumption involved
in assembly of an air-conditioner compressor in Virtual Design Lab. The actual workstation
used for assembly of the compressor is compared with a virtual workstation designed using
CATIA software. Results established using the MTM analysis of time consumed by actual and
virtual assembly operations are presented in tables and analyzed. The research has shown that
application of the MTM methodology combined with VR technology makes it possible to provide
fast testing of duration of assembly processes performed in a complex manner and to prepare their
implementation by taking into account several variants of parts configuration.
