AbstractThe role of mathematical models in engineering design is no longer that of simply automating techniques which were previously carried out manually. Throughout industry models are now becoming accepted as one of the main decision support systems to managers. This is certainly the case in engineering design for managing the environment. We are rapidly moving into the age of expert systems and hydro‐informatics, where the primary aim of most models is decision support. In this paper the role of the models in modern practice is reviewed and illustrated by case histories.

ABSTRACTThe problem of fair representation is studied in the case of cleavage according to one or two criteria. In the latter case we show that with minimal requirements of equity, a solution exists only if the two criteria are binary. This might explain an observed tendency to political bipolarization.

A formal mathematical model is used to explore the problem of fair representation in the case of cleavage according to one or two criteria. In two-criterion situations, a solution exists that meets minimal equity requirements only if the two criteria are binary. This may explain an observed tendency to political bipolarization. 5 Tables, 8 References. Modified HA
