FORMAL METHODS cum TECHNIQUES

- I was part of the team which first developed, researched and
applied
VDM: The Vienna Development Method.
- I was the instigator of the development of, research into and
am, today, a "user" of
RAISE: Rigorous Approach to
Industrial Software Engineering.
- I am interested in
all programming and software engineering
aspects of formal methods
-
- but prefer to call it
formal techniques.
- I have recently published three
textbooks
- with Springer -
on
"all" aspects of formal methods/techniques in
software engineering.
- On Computer vs. Computing Science:
- Computer Science is, to me, the study and knowledge
about the ``things'' that can exist inside computers: Data and
processes.
- Computing Science is, to me, the study and knowledge
about how to construct ``those things'': How to get problems
residing in the world outside the computer to be solved inside the
computer.
- As a consequence of this ``soft spectrum'' delineation we may claim that:
- Research in computer science proves theorems --
related to models of computation.
- Research in computing science ``proves'' methods:
Principles, techniques and tools -- related to perceived, ie.,
mental models of how people develop software.
- Computer science is more of a mathematical science,
- while computing science is more of an experimental and
explorative science (``discovering & testing'' relevant methods).
- The two go hand-in-hand, indispensably so.
- It seems more to be
- a ``smooth'' spectrum between the two,
- rather than two ``isolated'', discrete points.
- Further, we can say that:
- At my university and in our department we graduate
informatics engineers.
- That informatics is the convergence of mathematics, and
the computer &
computing sciences into software engineering applied to actual,
``outside the computer'', applications.
- The engineer ``walks the bridge'' between science and
technology:
- constructs technology based on scientific insight, and
- analyses technology so as to ascertain whether it
has scientific value.
- The technician composes technological artifacts,
basically without any need for scientific insight.
- The technologist is an engineer who deals with
technology in a socio-economic framework.
- The Paradigm:
- Before Software can be Designed its
Requirements ought be known.
- Before Requirements can be established the
Domain ought be understood.
- Hence I work in the triptych area of Domain Engineering,
Requirements
Engineering and Software Design.
- Together I call this Software Engineering.
- Main Research Interest: Programming Methodology
Thus programming, in my view, spans from:
- domain engineering via
- requirements engineering to
- software design.
By a method I understand:
- a set of principles
- for selecting and applying
- techniques and
- tools
- in order efficiently to construct
- an efficient artifact, here software.
So my endeavour is to
indentify, analyse and formalise (whereever the latter is reasonable)
such principles and techniques. At the moment I am primarily
interested in domain engineering, requirements
engineering, software architecture and
program organisation design. I have identified
a number of core domain engineering issues:
intrinsics, support technology, management & organisation,
rules & regulations, and human behaviour facets as these
also relate to domain stake-holder perspectives. Similarly
I have identified a number of core requirements engineering
issues. In particular domain requirements - with its
subsidiary techniques of projection, instantiation, extension
and initialisation. In domain engineering one
describes the domain without any
reference to Requirements. The new thing here is to establish
theories of domains -- as we have theories of such ``domains'' as
physics, biology, etc.
- Derived Research: Infrastructure System
Theories.
- On one hand there is the study of the concept of an
`infrastructure' and its `components'.
- On the other hand there is the study of
particular such infrastructure components.
As targets of the application of the above-mentioned
programming methodological ideas I apply these to such
infrastructure components as:
-
Transport:
Railways, Logistics, Air Traffic,
Airports, etc.
I am currently working on
a domain model for multi-modal
transportation nets.
This
documents is, as of January 12, rather incomplete.
Such models ought be of interest to companies like:
- Alstom,
- Alcatel--Dassault
Transportation (Thales),
- Atkins
(Denmark),
- Banestyrelsen: Danish National Railway
Authority,
- Bombardier Transportation,
- Copenhagen Airports,
- DSB: Danish ``State''
Railways,
- GE Transportation Systems, Global
Signalling,
- Pacific Railways,
- Scandinavian Airlines (SAS),
- Siemens Transportation Systems,
- Transvision
(Denmark),
I can provide references to many reports and publications concerning this
area.
The below entries will soon be equipped with appropriate URLs.
-
Financial Service Industry:
Banking, Insurance, Securities
Trading, etc.
Ought be of interest to companies like:
I can provide references to reports concerning this
area.
-
Healthcare Sector:
Flow of people, materials, information and
control in the healthcare secotr - patient medical jounrals being a
first study.
Ought be of interest to companies like:
We can provide references to reports concerning this
area.
-
Electronic Business / Electronic Government:
The published paper
... The
Market Domain ....
ought be of interest to companies interested in E-Commerce.
-
Project and Production Planning and Execution:
I am currently working on
a domain model of
manufacturing. This
documents is, as of January 12, VERY incomplete.
Ought be of interest to companies like:
I can provide references to reports concerning this
area.
- The Infrastructure Paradigm Question:
An aim is -- eventually -- to identify infrastructure component
theories, and thereby to better answer the question: ``What is an
Infrastructure ?''
