I hold a Ph. D in Computer Science from the Institut National Polytechnique,
Grenoble, FRANCE, last May 1998. This Ph. D was lead in collaboration between
an industrial parteneer, namely Dolphin
Integration, and Sherpa project
in INRIA Rhone Alpes. It adresses contextual
advice in design activity, when user is such an expert that hint have to
be justified in the context. This reaseach work was applied on an electronical
circuit simulator tool: Advisor is an on-line advice
system, already included in the SMASH simulator commercial release.
At present I carry on my work in Dolphin Integration in order to
let expert user complete Advisor knowledge for their specific application.
Part of this work has already been implemented in the Smash simulator.
Advisor option is available in the Eval Package of the Smash simulator
on Windows (95, NT).
This reasearch work is published in my Ph.D. thesis (see Publications
section for summary and complete thesis).
Advisor is the name of the contextual help proposed in SMASH tool. It helps
user to understand what is the purpose of all SMASH parameters, giving
explanation when a parameter is not relevant for a simulation or pointing
out influent parameter on currernt simulation. This module will include
in the future assistants to handle the simulator, and a case based reasoning
to learn expert solution when decision help given by rules is not efficient.
The present release of Advisor (release1.0) is able to detect "incorrect
way" of using the simulator according to general rules defined with expert
users. The interesting point is to be able to take into account the context
in order to comment inefficient user action.
Case based Reasoning
Advisor already includes a set of rules and in a near future it will
deal with cases, to let expert user reinforce Advisor learning on specific
application. Explanation of what integration de savoir_faire is all about
In Advisor1.1 all consensual rules are already handled by the contextual
help system. The next step is to help the user even when experts do not
share the same knowledge. Indeed, when a simulation algorithm is unable
to converge, it can be due to "too strict" accuracy parameters, inadapted
algorithm, or even bad modelisation of the circuit... Unfortunatly there
is not any knowledge on how to find out what cause the failure, thus experts
successively apply modification either at the parameter, algorithm and/or
circuit level. Giving advice will then mean in Advisor being able to list
only realistic hints according to the context, in order to share various
expert knowledge with other experienced designers.

At present I carry on my work in Dolphin Integration in order to let expert
user complete Advisor knowledge for their specific application (see section
Dolphin Integration internal project
As a member of the Solutions Department I also work on other Smash developements.
At present I take part in a European project on Fault Simulation.

I have been working for more than 3 years in Dolphin Integration. Advisor
development was lead in object-oriented langage (C++). Its integration
in SMASH simulator was an opportunity to work closely with Smash developement
Prior to my Ph.D. studies on Advisor, I studied Industrial Computer
Science in Engineer school 3I, Institut
des Sciences et Techniques de Grenoble, France.
