Application of MCDM Method in Selection of Schema for Optimal Design of Double Scissor Lift Tables

A scissor lift table is a valuable piece of industrial equipment. This device is used to lift objects or people. The double lift tables were used to achieve the extra reach for this equipment. There are numerous schemas for double lift tables in practice. Each schema will produce different values of output results when given the same set of input factors. As a result, determining the best scheme is critical when designing an optimal double lift table. The purpose of this paper is to present a study on multi-criteria decision making (MCDM) to determine the best scheme for designing a double lift table that meets two criteria at simultaneously: minimum lift time and maximum lift force. To gain this, nine different double lift table schemas were analyzed using the Multi-objective Optimization Ratio Analysis (MOORA) method for solving the MCDM problem and the Entropy method for calculating criteria weights. Finally, the best design scheme for a double lift table has been proposed.
