Highrisk variance of highest security risk Lowyield yield of lowest yielding security, Scalar target target mean annual return on portfolio % /10/, Set i securities /hardware, software, show-biz, t-bills/ * This model has been modified for use in the documentation This is a mini mean-variance portfolio selection problem described in $Title A Quadratic Programming Model for Portfolio Analysis (ALAN,SEQ=124a) We will discuss a simplified version of this model. is a portfolio selection model whose objective is to choose a portfolio of investments whose expected return meets a target while minimizing the variance. This output is covered in the chapters The Display Statement and The Put Writing Facility respectively. This chapter does not cover the output that can be generated by the user through display statements and put statements.

After covering all the components of the listing file we will discuss error reporting and conclude the chapter with a compiled list of how to customize the output file. The possibilities for extension to large models with voluminous output (which is when the diagnostics are really useful) should be apparent. The final components added to the listing file are the final execution summary and the file summary.Ī small nonlinear program will be used to illustrate every component of the listing file. The output generated when an external solver program processes the model is the solution report including the solve summary, the solver report, the solution listing and the report summary. The output generated during model generation contains listings of equations and variable listings as well as model statistics and possibly generation execution error messages. The execution output contains the results of display statements and possibly execution error messages. The compilation output contains an echo print of the input file, possibly error messages, along with lists of GAMS objects and cross reference maps. The main components in the listing file are: See chapter The GAMS Call and Command Line Parameters for more information. By default the listing file has the same file name as the input file, but this can be changed using the command line parameter Output. lst and can be read using any text editor. The output file generated from a GAMS run is called listing file. This chapter discusses the components of the GAMS output file generated from a GAMS run as well as ways to control the amount of diagnostic output produced. This connection string is stored in the project's App.config file.The output from GAMS contains many components in support for checking and comprehending a model. The following connection string references embedded model and mapping files for the AdventureWorks Sales Model. In Solution Explorer, double-click the App.config file and then modify the Metadata parameter in the connectionString attribute based on one of the following formats:įor more information, see Connection Strings. Repeat steps 1 and 2 for the storage (.ssdl) file and the mapping (.msl) file. In the Properties pane, set Build Action to Embedded Resource. In Solution Explorer, select the conceptual (.csdl) file. To maintain embedded resources, you must repeat this procedure whenever the model and mapping files are modified. When you manually define the model and mapping files, use this procedure to ensure that the files are deployed as embedded resources together with an Entity Framework application. By default, the Entity Data Model tools embed the model and mapping files. For more information, see Connection Strings. The assembly with the embedded model and mapping files must be loaded in the same application domain as the entity connection. The Entity Framework enables you to deploy model and mapping files as embedded resources of an application. How to: Make Model and Mapping Files Embedded Resources
