Nowadays
competition
among companies is rapidly increasing with the progress of technology. In order
to stand out in this competition environment, companies need to be renovated in
their own fields. Many companies use lean manufacturing techniques to achieve
this renewal.

In
this study, it is aimed to show how Analytic Hierarchy Process (AHP) is
one of Multi Criteria decision making method can be used as in choosing
which product line to initially apply value stream mapping method. The study
was performed in a company operating in the automotive sector. Criteria for the
AHP method were first determined by taking expert opinions and the most
suitable product line was selected by applying the AHP method. After that value
stream mapping has been applied to the determined product line. The future
state mapping is drawn up to improve the problems seen in the current state
mapping and a plan of action was presented for improvements.
