Abstract

Most of the times, the high-level decision process uses scarce knowledge and data, but has a huge impact over the entire design of an artefact or an organization. This paper is a contribution to help making the best decision, using only the expected ranges of variation of the requirements for each alternative design solution. As an application, this study focuses on the high-level decision between a chilled water and a direct expansion air conditioning system for a datacom centre. The decision depends on the cost and on the likelihood of failure, assuming that both systems have a suitable performance in what to the basic cooling function concerns. On the contrary to what is specified in most applications, cost applies herein for a functional requirement with specific ranges of variation. Moreover, one applies Axiomatic Design to the process of decision, rather than to the definition of the artefact. The collected data helps defining the ranges of variation of the afore-mentioned functions, which are the only records needed for the decision process. Notice that these ranges are also possible to obtain from a panel of experts in the field, making this approach to have a much more wide purpose when there is just a global understanding of the phenomenon under discussion.
