As the last modeling competition in the first half of 2022, the Electrician Cup will last for 72 hours. Among many modeling competitions, the Electrician Cup is a competition with high difficulty, short competition time and high popularity. In my personal opinion, the Electrician Cup can be the number one competition in the second echelon modeling competition under the US National Competition. Therefore, in order to better select the topic of the competition. In this competition, I will bring you a brief review of the competition questions in this article, so that you can choose the topic; at the same time, I will also share the problem-solving ideas for free, hoping to be helpful to everyone.
For detailed information on AB questions, you can read my other articles
Brief Comments on Question A
Energy storage operation and configuration analysis of high proportion wind power system
With the high-proportion wind power system as the background of the proposition, various calculation problems are set up, which can be regarded as a type of data calculation problem. First, we need to clearly give the various relationships of the data.
Brief Comments on Question B
Distribution of emergency supplies under 5G network environment
The essence of the optimization problem set in the background of the distribution model of "distribution vehicle + UAV" is still an optimization model. Here I have collected some excellent paper scoring rules for optimization models in the national competition for you, you can refer to them.
Question 1 is the simplest optimization model. This will be described later for everyone. In the second question, solid lines and dashed lines are introduced. The solid line represents the route that both vehicles and UAVs can take, and the dotted line represents the route that only UAVs can take. Other conditions are still the same as problem 1, here we need to change the constraints of the trajectory to achieve it. Question 3 is a modified version of Question 2. Only the maximum load capacity is changed. Here we can change the direct constraint conditions.
Question 4 is also the final question. In the title, to set up two emergency supplies concentration locations, we need to determine the best locations of the two emergency supplies concentration locations according to the situation. This question is different from the first three questions. Here we need Change the objective function for modeling.
game notes
A few notes about this game:
1. The registration for this competition will end on the 25th, which is this Wednesday. Don’t forget if you haven’t registered.
2. Do not ask for an agent to do it, but do it yourself. Even if you don’t come out the most, you have to do it yourself, because no one promises to do it for you. It must be done by yourself. Once you are caught, the consequences will be very serious.
3. The competition time is only 72 hours. Unlike the previous 4 days, this time there are only three days. Therefore, in terms of timing, I think some changes need to be made, I just give my personal opinion
Time schedule
On the morning of Friday, 27th , read the topic and discuss with teammates for preliminary discussion on topic selection
In the afternoon , I will update a brief review of the competition questions in this chapter. I hope it will be helpful to everyone’s topic selection. At the same time, Zhihu will update a lot of problem-solving ideas. At this time, I suggest reading more problem-solving ideas to determine the topic. . The topic selection is particularly important. We must determine the problems we may encounter in the future when we choose the topic, and avoid changing the topic halfway.
In the evening , start to collect various reference codes related to topic selection and initially start to conceive the model (relevant information will be updated in the afternoon)
On Saturday, the 28th , start the writing of the thesis (at this time, mainly write the supplementary parts such as problem restatement, problem analysis, model assumptions, etc.). At the same time, we began to implement the problem-solving model we constructed, which is the process of establishing and solving the model in our paper.
On Sunday, the 29th , the calculation of the problem was basically completed, and the writing of the model and the details of the thesis were started.
(In order to help everyone, the problem-solving materials for each problem will be released on Friday afternoon, and the semi-finished papers are expected to be released on Friday night or Saturday morning)
Finally, I sorted out some excellent papers for you, as well as the entry format of this competition, hoping to be helpful to you.
Finally, I wish you a happy competition and enjoy modeling.
