For dynamic natural resource models a few fundamental questions are often omitted in practice such as (i) “Is it possible to calibrate the model?” and (ii) “Can we reconstruct all unknown dynamic state variables given a certain data record?” Other related questions are (iii) “Does the system allow the state variables to be controlled (or managed) to desired optimal values (e.g., in case of maximum sustainable yield)?” In this paper we highlight and discuss a software tool (the StrucID App) that allows a rapid evaluation of these fundamental and structural model properties that are important to study before a calibration and subsequent simulation of the model.

计算自然资源模型的参数可识别性和其他结构特性

对于动态自然资源模型，实践中经常忽略一些基本问题，例如（i）“是否可以校准模型？” (ii)“我们能否在给定特定数据记录的情况下重建所有未知的动态状态变量？” 其他相关问题是（iii）“系统是否允许将状态变量控制（或管理）到所需的最佳值（例如，在最大可持续产量的情况下）？” 在本文中，我们重点介绍并讨论了一个软件工具（StrucID App），它可以快速评估这些基本和结构模型属性，这些属性对于模型校准和后续模拟之前的研究非常重要。
