A PRACTICAL FRAMEWORK TO EVALUATE AND SELECT ROBOTS FOR ASSEMBLY OPERATIONS

摘要

In robot assembly operations, the assembly cycle time is not linearly proportional to the maximum speed of the robot. Therefore, if the decision-maker wants to select and evaluate robots with respect to a specific assembly work, it is necessary to use the assembly cycle time to replace the maximum speed as an attribute in the evaluation process. This paper presents a methodology that uses assembly cycle time as an evaluation attribute instead of using robots' maximum speed. The resulting robot ranking is more realistic because the evaluation process considers the assembly jobs under consideration. Three computational examples are presented to support this conclusion.
