A note on system modelling, aggregation and reductionism.

Zeigler and Weinberg (1970) presented a system theoretic discussion of biological modelling. In this paper some implications of this formulation for the wider problem of reductionism are examined. It is argued that the reduction of biology to physics, for example, involves a relation between co-ordinates typical of biological models and those typical of quantum-mechanical models. This relation ...

The problem may be solved as an assignment problem and we establish several properties of optimal solutions in this problem.

A note on constrained OWA aggregation

Yager considered the problem of maximizing an OWA aggregation of a group of variables that are interrelated and constrained by a collection of linear inequalities and he showed how this problem can be modelled as a mixed integer linear programming problem. In this short communication we show a simple algorithm for exact computation of optimal solutions to a constrained OWA aggregation problem w...
