Overview and comparison of the four methods of elevator traffic analysis and design. It emphasises the fact that calculation and simulation are not mutually exclusive methodologies, and shows how they complement each other, where the former provides a starting design and the latter allows the designer to fine tune the lift traffic design. Practical application: This technical note provides a blueprint to lift traffic designers for the lift traffic design process. Changing speed, capacity of the lifts as well as the group control algorithm) in order to achieve the required average passenger waiting time and average passenger transit time. This technical note concludes by outlining the current hybrid method used by designers in lift traffic design, whereby one of the calculation methods is used to find a starting arrangement and then the design is fine tuned using one of the simulation methods (e.g. It also discusses the suitable areas of application of each of the methods, showing the strengths and weaknesses of each of the four methods. This technical note provides a general overview of each of the four methods. Moreover, the repeatability of the results is an important consideration, as well as the simplicity and calculation time of the method used. These methods vary in the level of computational complexity, as well as their ability to arrive at a value for the required performance parameters with acceptable accuracy and under the general case. Simulation can be split into discrete event simulation and time-slice simulation. Calculation can be split into main categories: analytical equation-based methods and numerical methods. These agents interact with each other through the main class where the rate of the arrival of passengers based on the data gathering is found, as well as the array list containing all four elevator agents, the passenger agents, and the floor agents.Lift traffic design can employ calculation or simulation methods.
Each agent can have its own presentation, flowchart, statechart, and variables. The agents modeled were the floor agents, elevator agents, and passenger agents.
Models of the building were made based on previous studies with modification in AnyLogic Professional 8.3.2.
Removing the elevator service going down optimized the current system and reduced the round trip time of the elevators as well as the waiting time of the passengers on high-rise buildings that use static zoning division.Īpplying agent-based modeling to create a passenger flow simulation gives a better understanding of how passengers interact with elevators, how they use them, and possibly how to optimize it based on the generated actions and decisions by the agents. The simulation will be modeled using data gathered from ID scans and CCTV footage. And to better understand how the system works along with its pitfalls, the environment, and the passenger flow will be simulated using agent-based modeling. Therefore, there is a need to improve the current elevator system. The next set of passengers still needs to wait approximately four minutes before they are serviced even if the elevators implement a static zoning division to reduce waiting time during peak hours. This happens because elevators transport a number of passengers above its planned capacity. Elevator traffic affects people who use elevators in high-rise buildings.
