The analytic hierarchy process (AHP) can be used to determine co-author responsibility for a scientific paper describing collaborative research. The objective is to deter scientific fraud by holding co-authors accountable for their individual contributions. A hiearchical model of the research presented in a paper can be created by dividing it into primary and secondary elements. The co-authors then determine the contributions of the primary and secondary elements to the work as a whole as well as their own individual contributions. They (...) can use the results to determine authorship order. (shrink)
