Several computational models have been developed in order to improve the outcome of Vein Graft Bypasses in response to arterial occlusions and they all share a common property: their accuracy relies on a winning choice of the coefficients' value related to biological functions that drive them. Our goal is to optimize the retrieval of these unknown coefficients on the base of experimental data and accordingly, as biological experiments are noisy in terms of statistical analysis and the models are typically stochastic and complex, this work wants first to elucidate which experimental measurements might be sufficient to retrieve the targeted coefficients and second how many specimens would constitute a good dataset to guarantee a sufficient level of accuracy. Since experiments are often costly and time consuming, the planning stage is critical to the success of the operation and, on the base of this consideration, the present work shows how, thanks to an ad hoc use of a computational model of vascular adaptation, it is possible to estimate in advance the entity and the quantity of resources needed in order to efficiently reproduce the experimental reality.

为了改善动脉闭塞静脉移植物旁路手术的结果,已经开发了几种计算模型,它们都有一个共同的特性:它们的准确性依赖于与驱动它们的生物功能相关的系数值的成功选择。我们的目标是在实验数据的基础上优化这些未知系数的检索,因此,由于生物实验在统计分析方面存在噪声,并且模型通常是随机和复杂的,因此本工作首先要阐明哪些实验测量可能足以检索目标系数,其次,多少个标本可以构成一个良好的数据集,以保证足够的准确性。由于实验通常是昂贵和耗时的,计划阶段对手术的成功至关重要,基于这一考虑,目前的工作表明,由于血管适应的计算模型的特殊使用,有可能提前估计实体和所需资源的数量,以便有效地再现实验现实。
