A Generalized Relational Model for Demographic Analysis
نویسنده
چکیده
Describing and analysing age patterns of vital events is one of the fundamental concerns of demography. Since the time the documentation of vital events began, the shape of mortality curve by age has puzzled the inquisitive mind. Its shape tended to vary with space and time. When attempts to capture the age variation in mortality by a single mathematical formula with only a few parameters proved elusive, demographers began constructing and tabulating 'model' life tables from empirical data. Such tabulations of model life tables have found extensive use in population projections and in making demographic estimation from incomplete or defective data.

A NEW APPROACH TO STABILITY ANALYSIS OF FUZZY RELATIONAL MODEL OF DYNAMIC SYSTEMS
This paper investigates the stability analysis of fuzzy relational dynamic systems. A new approach is introduced and a set of sufficient conditions is derived which sustains the unique globally asymptotically stable equilibrium point in a first-order fuzzy relational dynamic system with sumproduct fuzzy composition. This approach is also investigated for other types of fuzzy relational composit...
