7. CASE STUDY 2: ELEVATOR DESIGN
7.1 Introduction
In order to explore the research questions posed in Chapter 1 and to
expand more on integration of the proposed model with existing
methods, another case study was undertaken. The objective of this
case study is to apply the proposed method to a building design
problem which is complex in itself unlike the previous suspended ceiling
design example the complexity of which results only from interactions at
system level. Another objective is to demonstrate how parameter-based
DSM can be integrated with Industry Foundation Classes (IFC)s as was
proposed in Chapter 5.
The case study presented in this chapter analyzes an elevator design
process. The system architecture is first explained to familiarize the
audience with elevator systems. Then, elevator design process is briefly
outlined. Finally, the research process and the results are explained.
Since many methodological and practical aspects of this type of
research have already been discussed in Chapter 6, these are not
repeated in this chapter.
7.2 Elevator System Architecture
There are two general groups of elevators according to their type of
drives; namely, electric traction elevators and hydraulic elevators. An
electric traction elevator is a powered elevator to which energy is
