The paper is devoted to further development of numerical methods for simulation of riveting process during aircraft assembly (see [3, 4]). Algorithm modifications that increase computation accuracy, speed and complexity are given. These modifications involve the dual problem solving, incorporation of multiple calculation nets and special two stage procedure for calculation of deformations and stresses arising during assembly.

The paper is devoted to description of features and functionalities of special software complex aimed at global simulation of junction process using efficient numerical algorithms. The paper presents the concept of developed software and its structure. Types of problems, which the complex is applicable for, are enumerated.
