In view of the complexity, multi-constraint and multi-objective characteristics of production scheduling in process indus- try, an enhanced collaborative optimization algorithm (NCO) is proposed, which is applied to solve multi-objective optimization problems, and a multi-objective collaborative optimization method (MONCO) based on NCO is proposed. The simulation results show that MONCO algorithm can not only optimize the effect, but also reduce the number of iterations and improve the computa- tional efficiency

With the expansion of colleges and universities, the number of fresh graduates is increasing year by year, and the employ- ment pressure cannot be underestimated. Aiming at the problem of difficult employment, we conduct data analysis on the recruit- ment website, dig out the skills required for the job, and combine the results of the courses taken by the students when they are in school. Comparing the two, it is possible to recommend suitable jobs to the students and to the school, providing basis for job posi- tioning and job ability analysis in the professional talent training plan. The development of the position analysis system adopts the idea of separating front and back ends. The back end uses Hadoop platform and Spark framework. The front end uses Vue to bind da- ta. Echarts realizes visualization and visually displays the relevant data of the position. The post analysis system based on big data technology can obtain and analyze in real time, and visualize relevant employment data.

The emergence of VR technology brings new technical support for experiential learning. In order to explore the application effect of VR technology in experiential learning, the experiential learning situation model based on VR technology and student-cen- tered mode, enables students to experience the working situation of the real world in the virtual world and provides students with an environment to acquire highly practical learning skills. By designing an experiential learning situation model based on VR technolo- gy, this paper analyzes the various elements of the model, and carries out teaching cases under the guidance of this model, obtain bet- ter application effects, and provides mirror and reference for educators to explore the application advantages of VR technology in ed- ucation.

At present, the paper form is still used in the annual management assessment of teachers in many schools, which is not con- venient for management, also easy to make mistakes, and it is unable to view and analyze teachers' information in real time. In order to solve this problem, this paper designs an online teacher management assessment and data analysis platform based on the open source CCFlow workflow engine, which realizes the functions of annual assessment and declaration of teachers, data analysis, report printing, data archiving and so on, which improves the management level and efficiency of the school.

Courses reflecting the frontiers of disciplines, school charac- teristics and regional characteristics are added as elective subjects. Bilingual course, subject competition and enterprise project prac- tice are added too.

Programmable engineering calculator is mainly used in the field of surveying and mapping and civil engineering. So, field technicians must have the ability to design and use calculator programs. In this paper, by designing the simulation operating environ- ment of the program in QB64, the CASIO fx-5800P calculator program design, debugging and running scenes can be visualized in real time on the computer, which effectively improves the efficiency of learning.

As the course covers a wide range of content and needs lots of algorithms, students find it quite difficult. To solve these problems, as we found out that most algorithms in digital image processing has clear input image, input parameter and output image, this paper has come up with a teaching software of digital image processing experiment. In the software, every algorithm is designed as a module in the whole process. A digital image processing experiment can be accomplished by selecting different modules with given attributes and then be linked together. The software has a high degree of efficiency and has been well applied in experimental teaching.

In view of the characteristics of Database Principles and Applications course, such as more knowledge points and more de- tails, strong operability and less class hours, a question bank based on wechat small program is developed. This paper studies the ap- plication of rain classroom in teaching, uses the combination of rain classroom and the question bank to carry out teaching activities, and puts forward the course teaching mode based on mobile learning. Through the analysis of information statistics and interviews, the results show that this teaching mode improves students' interest and learning level and obtains good teaching effect.

This paper analyzes the major subjects faced by college students' information processing and maintenance in the informa- tion era and puts forward Ionic and other front-end technologies to design and implement the self-maintenance of Android APP sys- tem with student information. The system mainly realizes student information inquiry and filling, and simplifies the process of stu- dent information collection and processing during the epidemic. Ionic's cross-platform advantage is utilized to provide a strong refer- ence for the design model of application service in the smart campus constructions of colleges.

According to the characteristics of data mining course, this paper proposes to apply hybrid teaching mode to the teaching of this course based on SPOC. The use of SPOC platform can improve the teaching quality of teachers through online and offline teaching, fully mobilize students' interest in learning, and improve the learning effect.

Excellent online courses break through the limitation of teaching time and space, stimulate learners' self-study autonomy and enthusiasm, promote the sharing of high-quality teaching resources, and bring opportunities for the development of higher educa- tion.

The distributed network system of multi radar target monitoring usually includes polar coordinate system with radar as co- ordinate origin and rectangular coordinate system with command center as coordinate origin. However, due to the complex situation of different radar surrounding airspace environment and radar equipment, large sample standard deviation is prone to occur in the measurement of target distance, azimuth and elevation angle by single radar. In this case, according to the unified rectangular coordi- nate system, target position error transfer method, comprehensive index statistics method and other calculation methods, the mea- surement weight, variance and standard deviation of different coordinate components of the target object are analyzed statistically. After that, the weighted fusion model of multi radar tracks is used to verify the vertical weighted estimation value of limited radar measurement points in rectangular coordinate system, and then the result value of each element state of the target is determined.
