Mathematical model A mathematical model is a description of a system using mathematical language. The process of developing a mathematical model is termed mathematical modelling (also writtenmodeling). Mathematical models are used not only in the natural sciences (such as physics‚ biology‚ earth science‚ meteorology) and engineering disciplines (e.g. computer science‚artificial intelligence)‚ but also in the social sciences (such as economics‚ psychology‚ sociology and political science); physicists

3.4 Linear Programming Linear programming is one of the most useful types of word problems we learn in Algebra 2. It takes a collection of information and produces the best possible solution. However‚ each problem is unique. This requires an overall understanding of how to set these up. You need to buy some filing cabinets. You know that Cabinet X costs $10 per unit‚ requires six square feet of floor space‚ and holds eight cubic feet of files. Cabinet Y costs $20 per unit‚ requires eight square

Using Excel=s Solver Tool in Portfolio Theory Excel contains a tool called the Asolver@ that lets you maximize or minimize functions subject to general constraints. We will use this tool to compute the global minimum variance portfolio and the tangency portfolio for the three-firm example (see the spreadsheet 3firm.xls). The spreadsheet for this tutorial is called solverex.xls. The data for this example are given in the following table Stock 1 2 3 E[R] 0.229 0.138 0.052 VAR(R) 0.924 0.862 0.528

Introduction Markowitz (1952‚ 1956) pioneered the development of a quantitative method that takes the diversification benefits of portfolio allocation into account. Modern portfolio theory is the result of his work on portfolio optimization. Ideally‚ in a mean-variance optimization model‚ the complete investment opportunity set‚ i.e. all assets‚ should be considered simultaneously. However‚ in practice‚ most investors distinguish between different asset classes within their portfolio-allocation frameworks

programming focuses on obtaining the best possible output (or a set of outputs) from a given set of limited resources. The LPP is a class of mathematical programming where the functions representing the objectives and the constraints are linear. Optimization refers to the maximization or minimization of the objective functions. You can define the general linear programming model as follows: Maximize or Minimize Z = c1 x1 + c2 x2 +………….. +cn xn subject to the constraints‚ a11 x1 + a12 x2 + ……………
