I gave a general talk on this topic in 2013, at the Sauder School of Business, at the University of British Columbia, in Vancouver. The presentation used at the talk is below.

In this paper, we discuss one particularly challenging factor to Requirements Engineering projects, namely the change of…

Advice and Requirements in a Decision Problem

Dealing with Quality Tradeoffs during Service Selection

A service request is submitted to an automated service selector in the SoS, which allocates tasks to those service that, together, can “best” satisfy the given QoS criteria. When the selector cannot optimize simultaneously the given…
