Abstract

AbstractA lift table is a very common piece of equipment in industry and production. This device uses a scissors mechanism to lift goods or people. There are numerous schemas (or diagrams) for the scissors mechanism. With the same set of input parameters, each schema will produce a different set of output responses. As a result, to achieve optimum design of a lift table, it is critical to determine the best scheme. This paper presents the findings of a study that used multi-criteria decision making (MCDM) technique to determine the best scheme for designing a lift table to meet two criteria at the same time: minimum lifting time and maximum lifting force. To accomplish this, nine different diagrams of the scissor lifting mechanism were analyzed using the Measurement Alternatives and Ranking according to COmpromise Solution (MARCOS) method for solving the MCDM problem and the Method based on the Removal Effects of Criteria (MEREC) for the calculation of the weights of criteria. Finally, the best lift table design scheme has been proposed.KeywordsLift tableOptimal designMCDMMARCOSMEREC
