Lift Traffic Analysis for a Proposed Inner-City Development. A Comparison of the Lift Control Algorithms Considered

This account commences with an original enquiry regarding a proposed mixed development in Nottingham and the results presented to the client. The initial enquiry indicated the building will be subject to heavy mixed lunch time traffic. It was surprising to note the newest and most complex system, Hall Call Allocation, failed to satisfy the client’s and the BCO traffic requirements [3]. This investigation set out to examine why one control system appeared to perform better under certain conditions. Alongside academic research, traditional mathematical calculations and simulations were used to explore and test the differences. This paper outlines and examines three generic group control systems and explores the basic concepts and differences of each system considered for the project. This investigation also briefly reviews calculation and simulation and the differences these make to the way the control algorithms are considered and treated. The results of the various pre-design simulations, subsequent research and conclusions were somewhat unexpected. The differences were also surprisingly subtle. This paper briefly follows the research of the “Technical Report” prepared in support of the author’s application for C.Eng. registration earlier this year.
