Hot or cold forging is one of the most important processes that shape the materials in the industry. This process can be done very quickly with forging presses. Competition also has a big precaution in forging companies. Almost all commercial and passenger vehicles use forged parts. Crankshafts, connecting rods and front and rear axles are the main parts of these parts. Forging companies compete over time to produce these pieces. Because manufacturing these parts in less time means less cost.

One of the most important ways to reduce this forging time is to use new technologies and minimize downtime. After the forging process, defects that occur in the forging press or forging process that form this process are affecting both the quality of the product as well as the quality of the forged material. These failures can be caused by both production proses and maintenance failure. In the forging line, defects, postures or failures in production proses often occur in inadequate line organization planning or lack of education. Many areas of work on multi criteria decision making (MCDM) have been conducted. Some of the best known of these methods are TOPSIS, AHP and VIKOR. In this study, it was aimed to find out which forging line worked more efficiently with the VIKOR method, taking into consideration both the production and maintenance-oriented postures that occurred during the manufacture of a forging manufacturing method.
