Abstract
Engineering performance is a prime determinant of the successful implementation of industrial construction projects. Outcomes of engineering activities have a far-reaching impact on the entire life cycle of the project and quality of the constructed facility. However, there is a major lack of understanding of the interaction between a project's environment and its resulting engineering performance. With the current surge in developing industrial facilities, there is a need to have analytical schemes that relate engineering performance to its driving project variables and methods to further quantify this performance. The research introduces a generic system, which incorporates neurofuzzy computing with multiple attribute utility functions, for the assessment of engineering performance in industrial construction projects. Because of their fault-tolerance, and ability to model non-linear relationships and to handle imprecision in variable description, neurofuzzy systems are used for relating the measures of engineering performance to the set of project input variables identified to have the largest impact on such performance. The use of multiple attribute utility functions allows the generic system to simultaneously assess various measures of performance and provide a collective evaluation of the total engineering performance in the project. Questionnaire surveys were used to acquire data necessary for the generic system implementation. The system is further verified and validated for a proper adaptability and functionality. Statistical methods are employed for comparison purposes with the developed generic system. The study demonstrates the use of the generic system in several practical applications such as prediction of engineering performance measures, assessment of total and relative engineering performance, recognition of the project variables having the largest impact on engineering performance, among others.

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
