According to the problem of boarding time arranged, this paper first uses an implicit enumeration method, then checks for all possible programs to conduct a preliminary screening and gets a better boarding time arranged in steps. Secondly, we establish an analytic hierarchy model; in accordance with three typical of mill type (Small aircraft A320, medium-sized A757-300 aircraft and large aircraft A380), building mutual comparison matrix. Finally we get the optimal results.

The shadow price, which is determined for certain economic development goal to realize, can reflect the resources true value compared to the market price and promote to use the economical price of the resources reasonably. In this paper we design a resources purchase quantity algorithm which is based on the shadow price theoretical, A mathematical model and computer model simulation, establish a mathematical model and use computer to simulate. Finally this paper elaborates how enterprise management is instructed using the shadow price theory by the concrete example in order to raise enterprise's economic efficiency.

The water quality prediction is an important basis to implement water pollution control programs. In this paper, the gray system method is used to build a mathematical model of water quality prediction for the Yangtze River and using computer to simulate it to complete the implementation of the method for solving the model. Finally we find the method to solve problem of predicting the water quality of Yangtze River. The key problems are focused on the following two issues. (1) If we do not take more effective control measures, we make prediction analysis of the future development trendbased on past data. (2). According to the prediction analysis, we use computer to simulate that how much sewage we need to address each year.

The replacement problem of equipment is studied by employing the dynamic planning principle. This paper extends the present common dynamic programming model that only includes the decision-making of keep and replacement to the model that includes the decision-making of keep, replacement and general overhaul, and builds dynamic planning model for renewing machine equipment. Besides the program of the model is designed by means of C language, an example is given to illustrate the process of compute of the model.


Equivalence between a Boundary Value Problem with Obstacles on the Boundary and a Variational Problem

Contact problems widely exist in diverse fields. Many contact problems are induced to boundary values and variational problems. Boundary variational inequality methods have been playing crucial roles in contact problems fields, which induce all the boundary conditions and contact conditions to one variational inequality and make the theoretical analysis very easy. Variational problem is a bridge to solve boundary values by variational inequality. In the paper, a function is derived on the base of the functional of potential energy, and their equivalence between a boundary value problem with obstacles on the boundary and equal variational problem is proved. So the partial differential equation's boundary value with obstacles can be solved by the corresponding variational problem.

The elasticity contact problems with friction give rise to variational inequalities as their mathematical models. The main technical difficulties in solving these problems are to find their variational functions and numerical methods. The main numerical methods of variational inequalities contain finite element method and boundary element method - each has its advantages and disadvantages - and fast mutipole boundary element method, which overcomes the lack of traditional boundary element method in a certain extent and can be used to solve the large scale numerical computation and improve computation speed. Existence and uniqueness of the solution for a two-dimensional elastic contact problem with friction is made meaningfully in this paper. First, we give the partial differential equation for 2-D elastic frictional contact problem and boundary condition, also corresponding to variational inequality. Then, the existence condition of its solution is proved, which provides strong mathematical support for the solution of elastic frictional contact engineering problems.

... Water quality prediction involves forecasting changes in a water body's quality over time using actual measurements and mathematical models. Common methods include Artificial Neural Networks (ANN) [1], Grey Systems (GS) [14], and Support Vector Regressions (SVR) [6]. ANN-based methods are particularly popular, with hybrid models showing exceptional performance. ...
