项目摘要

In the proposed research we plan to analyze and improve the reliability, robustness and usefulness of numerical software for approximating the solution of differential equations. We will analyze and develop effective tools for the visualization and verification of approximate solutions and for investigating other issues of particular interest to practitioners developing mathematical models in a variety of different application areas. These areas include medicine, ecology, biology and finance. Our contribution and will not be to the development of new or better mathematical models, but rather we will provide a mechanism that will help practitioners understand and tune the parameters of their model to better fit the observed behaviour of the system they are modeling. The types of mathematical models we will focus on includes initial value problems (IVPs), delay differential equations (DDEs), boundary value problems (BVPs), differential algebraic equations (DAEs) and Volterra integro differential equations (VIDEs). For each class of problems, we plan to develop efficient procedures which can be used for error estimation, parameter fitting and sensitivity analysis that are valid even when the exact solution is discontinuous at a finite number of points. In our research we will identify and quantify the key trade-offs that inevitably arise between efficiency and reliability. Where possible we will develop software which allows the user to select from a small menu of available error control strategies. The more expensive strategies producing approximate solutions whose accuracy is much more likely to be within the prescribed error tolerance. We will present a rigorous asymptotic analysis of the approaches we implement. We will also perform sufficient testing on realistic problems to determine whether the behaviour predicted by our theoretical analysis is reflected on practical problems.
在拟议的研究中,我们计划分析和提高的可靠性,鲁棒性和实用性的数值软件近似微分方程的解决方案。我们将分析和开发有效的工具,用于近似解决方案的可视化和验证,并调查在各种不同应用领域开发数学模型的从业者特别感兴趣的其他问题。这些领域包括医学、生态学、生物学和金融。我们的贡献不会是开发新的或更好的数学模型,而是提供一种机制,帮助从业者理解和调整模型的参数,以更好地适应他们正在建模的系统的观察行为。 数学模型的类型,我们将集中在包括初值问题(IVP),延迟微分方程(DDE),边值问题(BVP),微分代数方程(DAE)和沃尔泰拉积分微分方程(VIDES)。对于每一类问题,我们计划开发有效的程序,可用于误差估计,参数拟合和灵敏度分析,即使在有限数量的点的精确解是不连续的。 在我们的研究中,我们将确定和量化效率和可靠性之间不可避免地出现的关键权衡。在可能的情况下,我们将开发允许用户从可用错误控制策略的小菜单中选择的软件。产生近似解的策略越昂贵,其准确性就越有可能 在规定的误差容限内。我们将提出一个严格的渐近分析的方法,我们实现。我们还将对现实问题进行充分的测试,以确定我们的理论分析所预测的行为是否反映在实际问题上。
