A fairly general model of the elevator system is presented. Coloured Petri Nets (CPN) and CPN tools are adopted as modeling tools. The model, which is independent of the number of floors and elevators, covers different stages of the elevator system in substantial detail. The model assists simulation-based analysis of different algorithms and rules which govern real elevator systems. The results...

this paper studies the extension mechanisms of the UML in the object oriented application and it introduces a new approach of using Stereotypes and shows its usefulness by implementing in an elevator control system. This paper also discusses the process of specifying, translating and verifying UML specifications for an elevator system. Different kinds of existing UML Meta-models used in an elev...

An elevator group supervisory controller is a control system that manages systematically two or more elevators in order to serve passengers as required. The elevator cars are assigned accordingly in response to hall calls, so as to optimize waiting time, riding time, power consumption, passengers’ comfort, etc. In this paper, the simplicity of ordinal structure fuzzy logic in making crucial sup...

Reinforcement learning (RL) comprises an array of techniques that learn a control policy so as to maximize a reward signal. When applied to the control of elevator systems, RL has the potential of finding better control policies than classical heuristic, suboptimal policies. On the other hand, elevator systems offer an interesting benchmark application for the study of RL. In this paper, RL is ...

The passenger service level in an elevator system depends on the planning of the elevator group and on the control of the elevators. In this thesis the contribution of passenger and elevator traffic for an elevator group with multiple shafts is studied by simulations and theoretical analysis. During this work an elevator control system, the Traffic Master System 9000 (TMS9000), was developed. T...

to evaluate the germination traits and mechanical damage of soybean seed during processing stages, anexperiment was conducted in a factorial experiment based on completely randomized design with 18treatments at mazandaran province (sari) in 2009-10. the experiment factors included different seedprocessing stages (before cleaning, after elevator, after pre cleaning, after cleaning, after drying ...

Recently, There are various approach for an elevator system based on information technology. And an elevator that has more than 20,00 parts for the building and use by many and unspecified people publicity as a means of transportation need to make the more secure and efficient management. For this purpose, the elevator systems require the more efficient network environment. But the service impl...

This paper presents a new modeling of elevator group intelligent scheduling system with destination floor guidance. The traditional input mode of separate hall call registration and the destination selection is improved to a single-input mode. On this basis, dynamic partition method in up-peak traffic is studied. This method means dynamically adjust division of floor region based on flow rate a...
