ABSTRACT
Chapters 4-8 have used calculation methods to design and evaluate the performance of lift installations. These calculation methods are based on mathematical models of the lift system. Other methods that have been discussed in Chapters 12-15 are based on the computer modelling of the lift systems to provide empirical formula. This computer modelling was carried out using a simulation program operating in batch mode.1 All calculation methods rely on simplifications and assumptions in order to make the calculations possible. Such simplifications and assumptions are discussed in Chapter 7. Other simplifications need to be made to deal with special situations, see Chapter 8.
