Abstract: University Timetabling Problem（UTP） is analyzed detailedly.An optimization mathematical model of UTP is established，and the framework structure to solve UTP is constructed.According to characteristics of UTP，GA is introduced.A variety of improved schemes are designed，which include：three-dimensional code scheme，initial population design scheme，fitness function design scheme，adaptive crossover probability and adaptive mutation probability design scheme.Simulation results show that the proposed GA can satisfy multiple constraint conditions and resolve UTP more effectively.

Key words: University Timetabling Problem（UTP）, Genetic Algorithm（GA）, three-dimensional code
