SIMPLE MODELS, CATASTROPHES AND CYCLES

J.L. CASTI

It is often observed in practice that the essential behavior of mathematical models involving many variables can be captured by a much smaller model involving only a few…

GENERALIZED PRINCIPLE OF OPTIMALITY IN PANSYSTEMS NETWORK ANALYSIS

WU SHOUZHI, WU XUEMOU

The optimization of a panweight network is studied. A generalized concept summary of optimality is established, which unifies various related principles. This may be viewed as a…

MODELIZATION OF SKELETAL MUSCULAR CONTRACTION; NUMERICAL APPLICATIONS IN RIGOR MORTIS AND IN MAGNESIUM‐CALCIUM METABOLISM

Fr. A. VALENTINI, P.P. NELSON

The numerical use of a general model of skeletal muscular contraction allows one to study some physiological phenomena. Rigor mortis is explained in terms of the ATP metabolism…

COMPARISON BETWEEN FUZZY INFORMATION SYSTEMS

M.A. GIL, M.T. LOPEZ, P. GIL

When we consider a decision problem under randomness and fuzziness, and several fuzzy information systems obtain, a comparison between them becomes interesting. In this paper, it…
