摘要：
The paper presents a new interval fast parametric integral equations system (IFPIES) for solving uncertainly defined potential 2D boundary value problems. The uncertainty of boundary shape and conditions was included in the definition of boundary shape and boundary conditions using interval numbers and modelled using modified directed interval arithmetic previously developed by the authors. The IFPIES allows for reducing the time of numerical computations and RAM utilization. The reliability and efficiency of the IFPIES solutions are proved by examples of 2D complex potential problems with uncertainly defined polygonal domains and boundary conditions.
