The objective of this study is to research certain integral inequalities with a parameter through the generalized (s, P)-preinvex mappings in the frame of fractal space. In view of this, we propose and investigate the conception of the generalized (s, P)-preinvex mappings and their related properties. Meanwhile, we establish an integral identity in the settings of fractal sets and present the parameterized integral inequalities for mappings whose first-order derivatives in absolute value belong to the generalized (s, P)-preinvexity. As applications with regard to local fractional integral operators, we consider applying the derived findings to v -type special means, numerical integrations, as well as extended probability distribution mappings, respectively. • The conception of the generalized (s, P)-preinvex mappings on fractal sets is proposed. • A refined integral inequality of the Hermite-Hadamard type for the generalized (s, P)-preinvex mappings is established. • Certain integral inequalities with a parameter for the generalized (s, P)-preinvexity are presented. • To illustrate the obtained results, some examples and applications are also given.
