查询词典 Model

First, the model is set up based on the traditional method of defuzzifying. Then a fuzzy nonlinear pragramming inventory model with fuzzy constraints is established by considering the fuzzy demand as fuzzy constraints. According to the principle of maximal membership grade, the model is transformed into a deterministic nonlinear programming to find out the optimal solutions.

Secondly, a joint pricing and capacity allocation model is formulated considering bulk demand. Chance constrained programming is used to transform the stochastic model. Numerical examples show our model and method is more near the simulation results than the deterministic programming and bigger learning coefficient leads to higher profit contribution.

接着，建立了考虑批量需求的BTO模式下制造企业定价与能力分配的集成模型，利用机会约束规划方法对此随机模型进行转化和求解，算例仿真表明机会约束规划方法较确定性规划方法更好地反映了随机连续需求的分布和波动特征，其期望利润贡献与仿真结果更接近；学习效率越大，最优价格越低，接受订单数量越多，期望利润贡献越高。

In the aspect of multivariate modeling, three forms of multivariate GARCHSK model includes vector form, diagonal form and simplify form, are put forward and compared. The famous dimension disaster exists in multivariate GARCHSK model also. Based on Independent Component Analysis, multivariate volatilities of conditional higher moments are estimated through IC-GARCHSK model, which make dynamic relation of higher moment risk between multi-assets to be possible.

鉴于多元 GARCHSK 模型存在严重的"维数灾难"问题，基于独立成分分解技术提出 IC-GARCHSK 模型，给出多元条件高阶矩波动率的估计方法，使得同时度量多个资产高阶矩风险之间动态关系成为可能，为利用组合投资方式分散高阶矩风险的影响奠定了方法论基础。

The derivation course and the discrete scheme of the first model-Perona-Malik model have been expatiated on emphasis. One item of the P-M model is omitted in the P-M's discrete scheme, and the gradient magnitude is replaced by the absolute value of difference quotient.

Perona-Malik给出的离散格式是一种显式离散格式，这一格式的连续形式省略了原模型中的一项，且用差商的绝对值代替了梯度模。

Nowadays, the study of modern model theory lies in the exploration time, and the study is limited in the area drilling of model. There are a substantial distinction between the construction of physical model and schema as discipline difference, although there are many learning models in mathematics that have been developed.

目前，国内关于现代图式理论在教学中实施的研究，尚处于探索阶段，研究大都局限于学科知识图式的训练上，虽然数学学科有关数学建模的研究较多，但因学科间的差别决定了物理模型与图景的建构与数学建模有着本质的差异。
