Development of simulation system for lift design

This paper addresses the work done in pursuit of an expert system for designing building passenger vertical transportation systems. The design and specification of lift systems for large buildings in a very complicated process, with a wide range of variables that need to be evaluated in order to design a system that will deliver acceptable performance. Such evaluation is performed with a help of a computer simulation software. The limited functionality of the currently existing programs for lift simulation prompted the authors to pursue a development of a new system, suitable for the demands posed by modern building designs and improved con-trol algorithms. The authors have completed the calculation and simulation modules together with the genera-tion of the visual simulation and building information model and the approach and methodology employed is described within this paper.
