Abstract
Appropriate risk allocation (RA) between public and private sectors according to their risk management (RM) capabilities is crucial for the success of public-private partnership (PPP) projects. The RA process in PPP water projects is examined, and a methodology based on fuzzy set theory is outlined with RA principles that can be used by public-private participants to arrive at fair RA decisions. Empirical data based on an industry-wide three-round Delphi questionnaire survey is used in this study to outline the methodology. The fuzzy set theory is employed for the RA analysis because it deals well with the complex multi-criteria problem of, and precisely accounts for the fuzziness inherent in human cognitive process that characterize, RA decision-making. Five risk factors are evaluated on each RA principle, analysed and assigned between the public and private sectors. The results show that it is appropriate to allocate risks according to both sectors' RM capability to manage them, using established RA principles and fuzzy set theory. The methodology renders the decision-making process more systematic and practical because the fuzzy theory approach allows decision makers to express their evaluations of both sectors' RM capabilities in descriptive qualitative terms. The results should assist public clients to establish efficient RA strategies and develop balanced RA schemes for PPP contracts, with a view to achieving a mutually acceptable RA with the private sector.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
