The Mathematical Programming Add-in constructs models that can be solved using the Solver Add-in or one of the solution add-ins provided in the collection.

When the Math Programming add-in is installed, several new command lines are added to the OR_MM menu. The menu items under the title Math Programming create models of the different types.

Selecting an item from this list causes a dialog box to be presented which constructs a mathematical programming model. Select one of the options in the left column of this page to get detailed instructions for specific forms of the model.

When a worksheet containing buttons is opened on a different machine than the one on which it was created, the buttons on the worksheet do not work. An attempt to use them will result in an error message. The Relink Buttons command deletes the buttons on a worksheet and creates new buttons linked to the add-ins on the new computer.

The models created by the add-in are solved with the Excel Solver, the Jensen Network Solver or the Jensen LP/IP Solver. All are Excel add-ins. Documentation for these programs can be reached by clicking the links on the lower left.

The Solver add-in comes with Excel, and it can solve linear programming, integer programming and nonlinear programming models. The Math Programming add-in automatically builds Solver models and calls the computational procedures that solve the problems. All four model types can be can be solved in this way.

The Jensen LP/IP Solver solves linear or integer programming problems. It is available for the Linear/Integer Programming and Network Flow Programming model types.

The Jensen Network Solver can solve generalized network flow models. Both linear and integer problems can be solved. It is available for the Network Flow Programming or Transportation model types.

To build and solve models, the Math Programming add-in and one of the solver add-ins must be installed. The Math Programming add-in can build models, but not solve them. The solver add-ins can solve models, but not build them. Follow the instructions given elsewhere for installing add-ins.
