Problems solved by technology

[0008] Moreover, using this kind of software only gives the final result without intermediate iterative process at all. It is just to get the final result and cannot show the process of doing the problem, so that it is impossible to learn the iterative idea of ​​simple algorithm, which is not suitable for students to understand the simplex algorithm. law study
Informatization teaching that cannot be extended to operations research courses
The process of solving the mathematical programming model is cumbersome and complicated, and you will lose a thousand miles if you are not careful
For the learners of operations research courses, there is only the final answer without detailed problem-solving ideas and steps, which cannot meet the needs of knowledge learning self-test and self-examination of error reasons

Embodiment 1

[0043] This embodiment discloses an operational research mathematical programming model learning assistance system applied to mobile phones, including:

[0044] The model input module obtains the selection instruction about the function to be used, as well as the number of variables, the number of constraint conditions and parameter values ​​in the model, and performs verification.

[0045] The parameters include variable coefficients and relational operators corresponding to each constraint condition. The relational operators include equal to, not equal to, greater than, less than, greater than or equal to, and less than or equal to.

[0046] As an implementation method, the system provides language prompts for users. For example, firstly, a function selection prompt is displayed "Please input the corresponding number to execute the corresponding function: 1. Linear programming problem calculation, 2. Integer programming problem cutting plane calculation"; After receiving th...

Embodiment 2

[0088] The purpose of this embodiment is to provide a learning aid method for operations research mathematical programming model applied to the mobile terminal, including the following steps:

[0089] Obtain the selection instruction about the function to be used, as well as the number of variables, the number of constraint conditions and parameter values ​​in the model, and perform verification;

[0090] According to the selected function, construct a mathematical programming model according to the given number of variables, number of constraints and parameter values, and solve it;

[0091] The solution process and intermediate results will be visualized.

Abstract

The invention discloses an operational research mathematical programming model learning auxiliary system and method applied to a mobile phone terminal. The system comprises: a model input module whichobtains a selection instruction related to a to-be-used function, and the number of variables, the number of constraint conditions and parameter values in the model, and carries out verification; anda model analysis module which is used for constructing a mathematical programming model according to the selected function, the given variable number, the constraint condition number and the parameter value, and solving the mathematical programming model. The model input method is simple and efficient, and the system occupies a small memory and is particularly suitable for the mobile phone terminal.

Description

technical field [0001] The invention belongs to the technical field of computer-aided mathematics teaching, and in particular relates to a learning assistance system and method for operations research mathematical programming models applied to mobile phones. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The network construction and information-based teaching of courses have been vigorously promoted due to their better teaching effects. However, for some science and engineering courses, such as mathematics courses, a large number of formulas and charts are required in the teaching process, and they can only be uploaded to the teaching platform in the form of pictures, which brings inconvenience to the information-based teaching of these courses. "Operational Research" is a compulsory course for mathematics majors. The optimization algor...
