Building University Spin-Offs from Research on Decision-Making

September 2018August 2021

This short interview on my research on decision making and use of it in companies, was done in 2018 with fnrs.tv, part of the Belgian Fonds de la Recherche Scientifique – FNRS, in Brussels. Each of my first two academic books led to the founding of a spin-off; see the books here.

Continually Learning Optimal Allocations of Services to Tasks

Open service-oriented systems which autonomously and continually satisfy users’ service requests to optimal levels are an appropriate response to the need for increased automation of information systems. Given a service request, an open service-oriented system interprets the functional and nonfunctional requirements laid out in the request and identifies the optimal selection of services-that is, identifies…

What Is Evidence?

There is no single definition of the term “evidence”, and trying to make one isn’t the purpose of this text. But there are ways of telling if something might be evidence, and knowing when it clearly isn’t. Such knowledge helps you develop a taste, so to speak, in evidence. Isn’t that valuable, given how frequently you may be giving evidence to support your ideas, and how frequently others do the same to you?

Dynamic Web Service Composition within a Service-Oriented Architecture

Increasing automation requires open, distributed, service-oriented systems capable of multicriteria-driven, dynamic adaptation for appropriate response to changing operating conditions. We combine a simple architecture with a novel algorithm to enable openness, distribution, and multi-criteria-driven service composition at runtime. The service-oriented architecture involves mediator Web services coordinating other Web services into compositions necessary to fulfill user…

From Decision Theory to Techne, and back

I gave two talks on the topic of qualitative decision analysis, which is what Techne was designed to support. At the time, we were looking for conceptual foundations for doing qualitative decision analysis, an alternative to standard decision analysis, which assumes richer information than what we typically have during requirements engineering and system design. Much…

Choice in Absence of Utility and Probability Estimates

In expected utility models, utility quantifies preferences, probability quantifies uncertainty. Sounds simple, elegant, but tends to be expensive. What if options can be identified, but there is no information about preferences or uncertainty in a format that can be translated into, respectively, utility and probability? What is an alternative decision process, which is still structured…
