Applying the Cauchy-Pompeiu formula and the properties of the singular integral operators on the unit disc, the specific representation of the solutions to the boundary value problems with the Dirichlet boundary conditions for bi-polyanalytic functions are obtained on the bicylinder. Also, the mixed-type boundary value problems of higher order for bi-polyanalytic functions were investigated. In addition, a system of complex partial differential equations with respect to polyanalytic functions with Neumann boundary conditions was discussed. On this foundation, the solutions to Neumann boundary value problems for bi-polyanalytic functions on the bicylinder were obtained. These results provide a favorable method for discussing other boundary value problems of bi-polyanalytic functions and the related systems of inhomogeneous complex partial differential equations of higher order in spaces of several complex variables.
