Vocational College Oriented Teaching Management System Design And Course Dispatching Algorithm Realization

Teaching management is the core work of school management, the work's complexity and integration need modern management methods. Teaching management lever can be promoted effectively by using the teaching management of information system (TMIS).Based on the real teaching situation of a vocational college, research demand of credit and year coexistence teaching management system in vocational education, teaching management of information system under the environment of Internet and LAN is designed in the paper.Based on analyzing the present situation, the characteristics, demand about vocational educational credit and year coexistence teaching management system, overall design scheme is proposed, system realization goal as well as functions and development mentality for vocational teaching management system are given. Design principle, development environment, various modules related function and business flow chart elaborated in detail, network database design, various subsystems design and man-machine surface have been done. In design duration, concise, highly effectiveness and extended principle have been considered, questions that should be paying attention to as well as user jurisdiction design are pointed out.Course dispatching arrangement subsystem are studied deeply in the paper, corresponding algorithm is designed and implemented. Firstly, the subsystem's objective and demand is carefully analyzed, then, multilayer layout idea is employed to establish mathematical model so as to transform the NP hard problem into polynomial increase problem. The model is a matrix which being composed of sets that serves as it's elements .To specific problem, heredity algorithm had been applied to get hypo-optimum solution step by step. In the heredity algorithm implementation, gene as well as fitness degree and cost functions are designed, single-point cross and variance operation have been improved, scale and generation number had been fixed on. The algorithm had been test in real circumstance, and the result shows that, curriculum arrangement efficiency promote dramatically. It is concluded that the algorithm can meet the demand of course dispatching arrangement for vocational college and have reference valuable to other similar system development.
