2021 Higher Education Club Cup mathematical modeling national tournament ABCD problem - problem solving ideas
2022-07-05 04:42:00 【The wind is a little strong】
Take a hole first
Need ideas :
A topic “FAST” Shape adjustment of active reflector
China Tianyan ——500 Meter aperture spherical radio telescope (Five-hundred-meter Aperture Spherical radio
Telescope, abbreviation FAST), It is the largest single caliber in the world with independent intellectual property rights in China 、 The most sensitive
Radio telescope .
Topic analysis
This type of question has appeared in Shenzhen Cup , Give you a new concept of practical application scenarios , Let you collect information , Then solve the specific problem , The Shenzhen cup is about the landing of the Mars spacecraft , But now it's replaced by a radio telescope .
This type of topic has some disadvantages :
Advantage is : They are all real projects , There are ready-made model solutions
The disadvantage is that : It takes a short time to understand many new concepts , And quickly grasp the practical significance of each part of the existing model , Equivalent to an open book exam , But the topic is difficult .
You may need to use : Operations research , physics , analogue simulation 、 Astronomy 、 Relevant knowledge of signal processing .
See the end of the article for detailed ways to obtain ideas
B topic Ethanol coupling preparation C4 olefin
C4 Olefins are widely used in the production of chemical products and medicine , Ethanol is produced and prepared C4 Raw materials for olefins .
In the preparation process , Catalyst combination ( namely :Co Load capacity 、Co/SiO2 and HAP Loading ratio 、 Ethanol concentration
The combination of ) With temperature C4 Selectivity and selectivity of olefins C4 Olefin yield will have an impact ( See Appendix for the explanation of terms ).
Therefore, through the catalyst combination design , To explore the preparation of ethanol by catalytic coupling C4 The process conditions of olefins are very important
Important significance and value .
Topic analysis
Topics that can be classified as data mining and analysis , Machine learning algorithms are needed , Analyze the data , classification , And prediction , It is suggested that students majoring in computer science choose this question .
See the end of the article for detailed ways to obtain ideas
C topic Ordering and transportation of raw materials for manufacturing enterprises
The raw materials used by a manufacturer of building and decorative plates are mainly wood fiber and other vegetable fiber materials , The whole can be divided into A,B,C Three types of . The enterprise is based on 48 Arrange production every week , It needs to be formulated in advance 24 Weekly raw material ordering and transfer plan , That is to determine the raw material suppliers to be ordered according to the capacity requirements ( be called “ supplier ”) And the corresponding weekly order quantity of raw materials ( be called “ Order quantity ”), Identify third party logistics companies ( be called “ Forwarder ”) And entrust the supplier to supply the quantity of raw materials every week ( be called “ Supply volume ”) Transfer to enterprise warehouse .
