Example: Defining users and locations

Specification of the user structure within the model

Location definition

For the purpose of this example the primary locations to be modelled will be the UK, New York, Europe and the primary and secondary data centres. These locations have been chosen to illustrate the use of different usage patterns across time zones, as well as to allow the effect of adding disaster recovery planning to be considered. For later use each of the locations also has a network node defined. In this case the nodes have simply been numbered sequentially for each of the locations. This will be discussed in more detail later.

Behaviour type definition

The next set of information to define is the behaviour types to be used in the model. In this case the main behaviour types being modelled are: Retail Banking, Corporate Users and Corporate Managers. To this are added behaviour types for the email processor and standing order processor, which will be used to model the batch processing within the system.

Behaviour type function usage specification

User Section Definition

Now the sets of users themselves can be defined to link locations and behaviour types. Thus, there would be corporate banking users and managers in the UK, New York and Europe. For this example, Retail baking users are only to be found in the UK, whereas the batch processors are located in the primary data centre. This is defined within the “User Section” sheet, which literally defines the different sections of users by their behaviour type and location giving each a representative name.
