Appendix B
Case Study Details
In this appendix details of the case study (Chap. 5) can be found. The outline of this appendix is
as follows. Section B.1 describes the architecture of the most important parts of the beam propeller
movement. Section B.2 lists some information that has been used to construct the model. Section
B.3 explains the model of the beam propeller movement in natural language. Section B.4 lists all
fault scenarios that could be extracted from the ServiceWax application, during the time span of
the project. Section B.5 lists the discretization that has been used to examine further improvement
of the model.
B.1 Architecture
The architecture that implements the beam propeller movement consists of three main parts. Figure
B.1 shows the physical location of these parts. They comprise of the following:
Backpanel control unit: This is the place where the control software and hardware are located.
It is comparable with the motherboard of a PC; by means of PCI it connects the hardware.
In this case the hardware consists of dedicated hardware boards (the so-called LUCs and its
extensions) and Motor Voltage Regulators (MVRs). The former are processing boards with
hardware and embedded software. They come in pairs: when an extension is connected to
