Abstract. Ambient systems owns some particular characteristics that
makes their context awareness a sincere problem; they are composed of
heterogeneous distributed devices, some of these devices may appear and
disappear during operations. In addition, users interacting in these systems are themselves dynamic. Therefore, context-aware workflow management allows workflows to adapt dynamically according to the environment changes. Context information are complex and diverse which
makes the modeling the key issue. This paper presents an approach to
model context-aware workflows. First, we describe the workflow using
Ag-LOTOS. Then, based on this description, we build the contextual
planning system CPSw that allows the presentation of the context at
each activity state.

1 Introduction
In order to meet the needs of everyday life, systems are becoming more and
more complex, which leads to seek to give more atomicity and initiative to the
different software modules. To respond to this technological evolution, ambient
intelligence [1] is a new paradigm of distributed systems where the environment
is aware of the user’s needs and find a way to fulfill that need to improve the
quality of people’s life.
Due to the extreme mobility of users, ubiquitous software [2] run in a highly
dynamic and varying environment. Therefore, context awareness [3] and context
adaptation [4] are some important aspects for pervasive software that have to
be aware of the context’s changes, and dynamically adjust their execution [4].
Context-aware workflow [5] is an interesting field that allows workflows to adapt
dynamically to the context changes in ubiquitous environment.
To achieve this goal, no many results have been accomplished in workflow’s
context modelling. [6] proposes a context-aware workflow management system
