The book is divided into five sections: 1 The Business Model Canvas, a tool for describing, analyzing, and designing business models, 2 Business Model Patterns, based on concepts from leading business thinkers, 3 Techniques to help you design business models, 4 Re-interpreting strategy through the business model lens, and 5 A generic process to help you design innovative business models, tying together all the concepts, techniques, and tools in Business Model Generation. The last section offers an outlook on five business model topics for future exploration. Finally, the afterword provides a peek into “the making of” Business Model Generation

Some Properties 1. ∆n is consistent. 2. Γ ⊆ ∆n ⊆ ∆n+1 ⊆ ∆Γ 3. ∆Γ is complete. 4. If ∆Γ ` A then there exists n ∈ N such that ∆n ` A. 5. A ∈ ∆Γ iff ∆Γ ` A 6. ∆Γ is consistent

4-1设有一个二维数组A[m][n]),假设A[0][0存放位置在644(1),A[2][2]存放位置在676(10),每个元素 占一个空间,问A[3][3](10)存放在什么位置?脚注(10)表示用10进制表示

Individuals are the objects described by a set of data. Individuals may be people, but they may also be animals Relationship or things Between Variables A variable is any characteristic of an individual. a variable can take different values for different ndividuals The 1997 survey data set, for example, includes data about a sample of women The individuals described are the women

每一个事件都有它的发生概率 即给定事件A,存在着一个正数P与之对应, 称之为事件A的概率,记作P(A)或P{A} 最高的发生概率为1,表示必然发生. 最低的概率为0,表示不可能发生. 而一般的随机事件的概率介于0与1之间. 这里只是概率的数学上的规定,其实就是任 何一个事件到实数轴上的[0,1]区间的映射. 但怎样获得切合实际的一个事件的概率呢?

3.1矩阵的秩 1.子式:在An中,选取k行与k列,位于交叉处的k2个数按照原来的 相对位置构成k阶行列式,称为A的一个k阶子式,记作D 对于给定的k,不同的k阶子式总共有C个 2.矩阵的秩:在A中,若 (1)有某个r阶子式D,≠0; (2)所有的r+1阶子式D+1=0(如果有r+1阶子式的话) 称A的秩为r,记作 rankA=r,或者r(A)r.规定:rank0=0 性质:(1) rankA min{m,n}

National Income: Where t comes From and where丨 t Goes A large income is the best recipe for happiness I ever heard of. Jane Austen The most important macroeconomic variable is gross domestic product(GDP) As we have seen, GDP measures both a nations total output of goods and ser- vices and its total income. To appreciate the significance of GDP, one need only take a quick look at international data: compared with their poorer counterparts, nations with a high level of gDP per person have everything from better child-
