The National College Mathematical Contest in modeling was revised in September 12, 2008Edit the competition GuideWhat is mathematical model and mathematical modeling?Simply put: mathematical models are a mathematical expression of practical problems. Specifically, the mathematical model is an abstract, simplified mathematical structure of some real world for some purpose. Rather, the mathematical model is for a specific object to a specific target, according to the unique inherent laws, make some simplifying assumptions necessary, using appropriate mathematical tools, a mathematical structure is obtained. Mathematical structures can be mathematical formulas, algorithms, tables, diagrams, etc.. Mathematical modeling is the establishment of mathematical models, the process of establishing mathematical models is the process of mathematical modeling (see mathematical modeling process flow chart). Mathematical modeling is a mathematical thinking method, is the use of mathematical language and methods, through the abstract and simplify the establishment of an approximate description and "solve" practical problems of a powerful mathematical means.First, the mechanism analysis method: the model is deduced from the basic physical law and the structural data of the system. 1. scale analysis -- the most basic and most commonly used method to establish the functional relationship among variables. 2. algebraic method -- the main method for solving discrete problems (discrete data, symbols and graphs). 3. logic method is an important method of mathematical theory research. It is widely used in the fields of sociology and economics, in decision-making, countermeasures and other disciplines. 4. ordinary differential equation - to solve the law of variation between two variables, the key is to establish the expression of "instantaneous rate of change". 5. partial differential equation -- solving the law of variation between dependent variable and more than two independent variables. Two. Data analysis method establishes mathematical model by using statistical method from a large number of observation data. 1. regression analysis - a set of observations (Xi, FI) i=1,2 for function f (x)... N, which determines the expression of a function, is called a mathematical statistical method because it is a static independent data. 2. time series analysis deals with dynamic related data, also known as process statistics. 3. regression analysis - a set of observations (Xi, FI) i=1,2 for function f (x)... N, which determines the expression of a function, is called a mathematical statistical method because it is a static independent data. 4. time series analysis deals with dynamic related data, also known as process statistics. Three, simulation and other methods 1. computer simulation (simulation) - essentially statistical estimation method, equivalent to the sampling test.Discrete system simulation - there is a set of state variables. Continuous system simulation with analytic expression or system structure diagram. 2. factor test method -- local test on the system, then according to the test results for continuous analysis and modification,The required model structure is obtained. 3. artificial reality method, based on the understanding of the past behavior of the system and the desired future goals, and taking into account the possible changes in the relevant factors of the system, artificially forming a system. (see: Qi Huan, mathematical modeling method, Huazhong University of science and Technology Press, 1996)IV. types of questionsMatch questions structure has the following parts: background, problems involving wide 1. - social, economic, management, life, environment, natural phenomena, engineering technology, modern science in the new issue. 2. generally, there is a definite practical problem. Two, some assumptions are as follows: 1. only the process and rules of qualitative assumptions, no specific quantitative data;2. are some survey or statistics;3. gives a number of parameters or graphics;4. contains some assumptions of mobility, can play, or players can according to their own collection or simulated data. Three, asked to answer the question often have several problems (generally not only answer: 1.) more definitive answers (basic answers); 2. more detailed or high-level discussion results (often is the optimal scheme formulation and results).Competition answer paperTo submit a paper, the basic content and format is roughly divided into three parts: first, the title, abstract part:1. topics - write a more precise topic (not only write A,B). 2. Abstract --200-300 words, including the main features of the model, modeling methods and main results.3., when there is more content, it is better to have a directory. Two, the central part: 1. problem raised, problem analysis. 2. models: the complementary hypothesis, clear concept, the introduction of the model parameters; form (with multiple models); for the model; the model of nature; the realization of computer design and calculation method of the 3.4. result analysis and test.5. discuss the advantages and disadvantages of the model, improve the direction, and promote new ideas.6. references -- attention format. Three. Appendix: 1. calculation program, block diagram. 2. solving the calculus and calculating the intermediate result. 3. various graphics and forms.Edit this paragraph competition questions collection1992

impetus for the contest of mathematical modeling. At present, the first domestic mathematical modeling company - Beijing Noah Mathematical Modeling Technology Co., Ltd. was established in Beijing. Wei Yongsheng, a doctoral student, worked with two other like-minded students in the field of entrepreneurial modeling, from the domain of mathematical modeling that they were familiar with. Wei Yongsheng three people set up a mathematical modeling contest team in April 2003, then won the two prize of state, in 2005 won thefirst prize in the international contest of mathematical modeling, the same year in October registered the mathematical modeling in mathematical modeling enthusiasts website, to society, to the direction of the application, they formally established in June last year to the application mathematical modeling for entrepreneurial direction, the formation of entrepreneurial team, opened the road of entrepreneurship. Earlier this month, Beijing's mathematical modeling technology limited company officially registered, Wei Yongsheng entrepreneurial team officially on track. At present, Noah mathematical modeling is its specialization from the perspective of business to expand its strength, mathematical modeling and mathematical model and actively involved in the railway transportation, highway transportation, logistics management and other related solutions and consulting services. Wei Yongsheng explained to reporters, maybe a lot of people do not understand what is the use of mathematical modeling, he cited an example of a train station, to calculate how long a car can not only ensure the passengers were taken away, and to the greatest degree of cost savings, the mathematical model can be calculated by the optimal scheme.Wei Yongsheng said that their mathematical modeling team has been 6 years of history, with each other, very tacit understanding, but also made dozens of large and small projects. Their business philosophy is to provide a hitherto unknown mathematical modeling and mathematical model of optimal solutions for the direct and potential customers, minimize production cost, realize investment income for the customers.
