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 prove the compatibility and applicability of this model in various situations and demonstrate the expressive power and convenience of CPN. / Thesis / Master of Applied Science (MASc)

Constant product development for integration and optimization is a crucial part of companies today. With industrial components comes the challenge with how these parts can be integrated and optimized the best for the system. One example is a hydraulic elevator system, to integrate and optimize the design, the rest of the valve system has to be taken into consideration. This thesis contains the integration and optimization of a check valve solution designed with the help of the product development process in hopes of reducing costs for the manufacturing process for the company. The thesis resulted in an optimized check valve solution with 6 bolts connected with the hydraulic elevator valve system. The requirements were fulfilled but some were not possible to achieve without a physical copy.
