This study inspects the influence of various effects and free parameters of the accretion disc and circumstellar material on the emerging light curve of eclipsing binary systems that have a circumstellar disc, by using the SHELLSPEC code. The results indicate that some of the parameters namely the temperature and inclination of the disc, spot, jet, stream and shell significantly affect on the emerging light curve while some other parameters namely the exponent of the power-law behavior of the density of the disc, microturbulence, inner and outer radius of the disc don't noticeably affect on the emerging light curve. An application to the Algol-type eclipsing binary system AV Del and an accretion disc model for the system using the SHELLSPEC code is included.
