WebThe utilitarian redundancy model (URM) enables a simple and objective evaluation of the functionality of knowledge systems based on species known to perform similar functions. It emerges from the redundancy model in ecology that analyzes, from a functional perspective, the use of natural resources by human populations. WebThese last two definitions of rate transition matrix derived from the transition availability are given by (5) and (6), respectively: matrix P. 1 T (5) THE PROPOSED REDUNDANCY MODEL a= a (t ) dt T 0 (6) Now, we present our model and formalize some of A = lim a(t ) the concepts introduced earlier.
