and, if necessary, adapt the distribution of business processes in the different
categories and/or modify the adaptation to categories made in each business process.
As a result, the distribution of business processes in each category and their
adaptation must be a pluridisciplinary work in which different disciplines are
involved, as much in the field of ICT as in that of social sciences. At this level we
must therefore have a decompartmentalization of disciplines, and this is probably
one of the major challenges for the integration of the notion of travel time
experience in interactive applications in the field of transport.

Categories of the travel time experience of users
Dealing with the categories of travel time experience in conceptual models can
be done on several levels in the context of our model-driven modeling approach
[BRO 08]:
- in the business rules, like all criteria of the user profile;
- in the business process models;
- in the static interaction models.
The business rules [OMG 05] enable part of the business logic of business
processes to be extracted, making them easier to modify. A definition of the
business rules is given by [BRG 00]: “
A business rule is a declaration which can be
evaluated and that defines or restricts certain aspects of the business. It has the aim
of affirming the business structure or to control or influence the behavior of the
business. For a given project, the business rules are atomic, that is to say that they
cannot be redefined into smaller elements
”.
In the context of our approach, we have defined three types of business rules:
- so-called validation rules, the evaluation of which returns a Boolean-type value
(true or false);
- selection rules, the evaluation of which returns a value that can be a chain of
characters, a date or a number;
- action rules, the evaluation of which will set off a particular action.
With business rules, the use of information regarding the category of travel time
experience of the user is incorporated as with any other information in the profile.
To give an example, we can see a validation-type business rule “
IsABeaver
” below
that enables us to determine whether the user is part of the
beaver
category.
