摘要

我们为S-PALPS定义了一个平均场语义,这是一个用于空间显式、基于个体的生态系统建模的过程演算。S-PALPS的新语义允许将系统的平均行为解释为一组递归方程。在处理大量个体时,递归方程是一种有用的近似值,就像在流行病学研究中一样。作为一个案例研究,我们计算了一组递归方程,捕捉了哥伦比亚贝罗(安蒂奥基亚)登革热基于个体的传播模型的动态。

Mean-Field Semantics for a Process Calculus for Spatially-Explicit Ecological Models
We define a mean-field semantics for S-PALPS, a process calculus for spatially-explicit, individualbased modeling of ecological systems. The new semantics of S-PALPS allows an interpretation of the average behavior of a system as a set of recurrence equations. Recurrence equations are a useful approximation when dealing with a large number of individuals, as it is the case in epidemiological studies. As a case study, we compute a set of recurrence equations capturing the dynamics of an individual-based model of the transmission of dengue in Bello (Antioquia), Colombia.
