The course design of Operational Research Practice is a whole-process comprehensive training, which is based on team work, learning the teaching content of Operational Research, independently selecting topics, conducting research, data retrieval, demonstration or analysis modeling, solving and other processes under the guidance of teachers, and drawing conclusions and giving the optimal decision-making scheme after full discussion. It is an important practical link, and it is important for cultivating and improving undergraduate students' scientific thinking, scientific methods, practical skills and innovation. It is embodied in creative thinking ability, scientific research ability, such as the ability to analyze and solve practical problems, the ability to quantitatively analyze and use computers, the ability to synthesize and express, the ability to cooperate with teams, and the ability to coordinate and respond. I. Topics for Course Design of Operational Research Practice Some topics listed below can be used for reference: 1. Design several sets of recipes with different requirements for students in their classes; 2. Design several sets of personal savings plans for the students; 3. According to the specific situation of the students in the group, design several sets of study schedule schemes that vary from person to person; 4. Reasonable design of self-study seats in the reading room of the library (reasonable design of the number and layout of dining tables and stools); 5. Select an enterprise, and make an optimized production scheduling plan or production-inventory plan according to the actual investigation; 6. Help a rural township to make a crop planting plan; 7. Make a reasonable car allocation plan for a transportation enterprise; 8. Make a reasonable vehicle renewal plan for the bus company; 9, choose the product background of the enterprise, and solve the reliability problem of series system; 11, choose the background, solve the problem of site selection, such as automatic inflation station, emergency center, blood station, hospital, school, power plant, refinery, warehouse, distribution center, threshing floor, etc.; 11, the rational allocation of the number of doctors in hospital departments (student supermarkets, bookstores, canteen attendants); 12. Design of classic routes of tourist attractions in Xi 'an; (The design of the shortest contact route in colleges and universities; ) 13, select the actual background that you know and are familiar with, collect relevant information, abstract an appropriate operational research model, solve it and analyze the results to form an operational research case; 14. Choose an interesting question from the case background materials provided by the teacher for research; 15. In view of the key points and difficulties in course learning, design corresponding auxiliary learning tools, such as LP sensitivity analysis activity ruler, electronic template method to solve network model, queuing theory formula summary and memory table, etc. 16. Select a module of the teaching network platform of Operations Research for system analysis, design and development; 2. Class hours and activity arrangement 1. The total class hours are 2 weeks, and the activity content and time arrangement are as follows: activity content selection, research group discussion and answering questions on the computer, instruction report exchange and summary class hours 1 week 16 class hours 12 class hours time arrangement 1-15 week 16~17 week 15 week 516 week 5 18 week 2, 5 total class hours 2 weeks 2. Organization work and activity arrangement: (1) topic selection and research stage: arranged in The main work is: 6? 1 within 2 weeks of the class-divide the group and select the team leader; ? 6? 1 group topic selection-teachers constantly provide students with topics and research suggestions with the course teaching process, and group members should communicate frequently, and determine the topic selection after soliciting teachers' opinions after the opinions are basically unified; ? 6? Division of labor among team members; ? 6? 1 data collection and investigation; (2) Discussion stage: In addition to the usual scattered communication, 3~4 units are arranged for discussion, and 2 units are arranged for teachers to answer questions and provide advice and suggestions for curriculum design. The main tasks at this stage are:? 6? 1 group discussion research (including supplementary research)? 6? 1 computer calculation? 6? 1 form a research report and a work report, and make a presentation ppt.(3) Exchange and comment stage: arrange three units in a centralized way. The main tasks are:? 6? 1 The whole class exchanges reports, questions and discussions (debates)? 6? 1 teacher comments summary? 6? 1 Revise the research report (4) Report submission stage of Curriculum Design: (before July 1, 2119) The final results will be submitted in the form of group reports, including: ① Research report; ② Work report; ③ Presentation PPT. Report writing requirements: The purpose of writing the report of Curriculum Design is to cultivate students' standard and good scientific research style. According to the requirements of writing scientific research papers, the writing format includes two parts: research report and work report. The writing format is as follows: 1. Research report is the main achievement of Curriculum Design, which should reflect the research content and results, mainly including the collection and arrangement of background information, data, demonstration, or modeling calculation and results. The writing format of the report should refer to the writing of scientific research papers, and the specific requirements are as follows: (1) title (with signature under the title) (2) abstract (3) keywords (4) body? 6? 1 Question raising (significance and background of the topic)? 6? 1 data collection and collation? 6? 1 demonstration or modeling and calculation
