Fractional integro-differential equations (FIDEs) constitute an important mathematical tool in modeling many dynamical processes. To solve FIDEs, several analytical and numerical methods have been proposed, namely those based on sym

In this study, a spectral collocation method is proposed to solve a multi-term time fractional diffusion-wave equation. The solution is expanded by a series of generalized Laguerre polynomials, and then, by imposing the collocation nodes, the equatio

Regional bank branch management is the most important elements of a bank’s structure. Each regional bank branch manager (RBBM) manages a large group of branches. In this paper, we develop a bi-level structure for the evaluation of RBBMs. In the dev
