Introduction As the needs of highly competitive products, the increasing complexities of engineering design, and the uncertain nature of engineering world, over the last 10 years there has been an increasing trend for analysing mechanical structures using probabilistic information of loads, geometry, material properties, and boundary conditions.

Analysis of the course scheduling results of teachers The course scheduling result of teacher 28 is selected randomly as an example, as shown in the following Table 4： Time Monday Tuesday Thursday Thursday Friday 1-2 Civil engineering materials, 1-16, B404, Civil engineering1001 3-4 steel structure, 1-12, B309, Civil engineering 1001 5-6 structural mechanics, 1-12, B309, Civil engineering1001 As shown in Table 4, it can be seen that the time of the courses of teacher 28 is arranged reasonably, with intervals between two courses, which can meet the course preparation arrangements of teacher 28, so the course scheduling result meets the available and reasonable conditions. 5 Conclusions The experiment results show that the method of course scheduling presented in the paper is feasible and effective.
Satisfactory course scheduling results are achieved using the method presented in this paper, which solves the hard conflicts mentioned in the paper, and also meets some soft constraints to the largest extent. 6 Acknowledgment This Article was Supported by for Basic Scientific Research of Central Colleges, Chang’an University and the Support Plan Special Fund of Chang’an University Basic Research CHD2011JC116(2011209); Ministry of housing and Urban-Rural Construction Soft Science Fund(2011-R1-26;20ll-R3-19); Shaanxi Soft Science Fund (20llKRM20);Shaanxi Social Sciences 2012 major theoretical and practical issues research project (2012C008); Highway Maintenance under Low Carbon Economy (2171-20130186).Thanks for professor Yi-fan Tang’s kindness and help, and assistant professor Hai-yan xie (university of Arkansas Little Rock, USA)’s constructive suggestion. 7 References [1] Xia Xiao-yun, Gao Wu-Jun.The Making Class Schedule System of High School Based on Genetic Algorithms[J].
