Investigation of Optimization Techniques on the Elevator Dispatching Problem

Abstract

In the elevator industry, reducing passenger journey time in an elevator system is a major aim. The key obstacle to optimising elevator dispatching is the unpredictable traffic flow of passengers. To address this difficulty, two main features must be optimised: waiting time and journey time. To address the problem in real time, several strategies are employed, including Simulated Annealing (SA), Genetic Algorithm (GA), Particle Swarm Optimization Algorithm (PSO), and Whale Optimization Algorithm (WOA). This research article compares the algorithms discussed above. To investigate the functioning of the algorithms for visualisation and insight, a case study was created. In order to discover the optimum algorithm for the elevator dispatching problem, performance indices such as average and ideal fitness value are generated in 5 runs to compare the outcomes of the methods. The goal of this study is to compute a dispatching scheme, which is the result of the algorithms, in order to lower the average trip time for all passengers. This study builds on previous studies that recommended ways to reduce waiting time. The proposed technique reduces average wait time, improves lift efficiency, and improves customer experience.

“…The total loads on the bearings (Tsl) are the sum of Tcs, Tcw and Owb values. For the lifetime calculation, the loads per bearing are calculated with the equations in (1)(2)(3)(4)(5)(6). As a result, the load acting per single bearing was obtained as 5381.88 N. 𝑀 𝑐𝑠 = 𝑄 + 𝑊 𝑐 + 𝑊 𝑓…”

“…Due to the increase in the number of passengers and cargo loads in high-rise buildings, there was a need to increase cabin capacities. The capacity increase is a more suitable method since the installation of another elevator system will be costly [1]. Since increases in car load have a direct effect on the motor shaft and connection parts, they should be taken into account in the design and selection of the elevator motor.…”
