Building a Page

Even thoughAimmsprovides standard pages for each identifier, such pages are not set up to look at groups of related identifiers. That is why model builders and end-users of an application usually prefer to interact with an application through one or more custom pages.

6.1

Creating a new page

To create a new empty page you should execute the following steps:

 press thePage Managerthe toolbar,button on  press the button on the toolbar to create a new page,  specify ‘Beer Transport Input and Output Data’ as the name of this new page, and  press the Enter key to register the page.

ThePage Managerwith the new page is shown in Figure6.1.

Figure 6.1: A Page Manager with a single page

Note that changes made in the previous chapter to the lay out of the Transport data table are also saved in the Page Manager.

6.2

Presenting the input data

A page is either inEditmode or inUsermode. TheEditmode is used for creating and modifying the objects on a page. TheUsermode is for viewing and editing the data displayed within objects on a page.

Building custom pages

Using the Page Manager

Be aware of two page modes

To open the new page inEditmode:

Chapter 6.

Building a Page

 double click on the page name in thePage Manager, and  button on the toolbar to open the selected page inpress the Editmode.

To create a new table, perform the following actions:

 on the toolbar,press the new-table button  position the mouse cursor at where the upper left corner of the new table should be,  depress the left mouse button and drag the mouse cursor to where the lower right corner of the new table should be, and  release the mouse button.

You can now complete the identifier selection dialog box as follows:

 select the parameter ‘UnitTransportCost(p,c)’ in the identifier selection wizard as illustrated in Figure6.2,  press the Next button,  press the Finish button, and if necessary  adjust the position and size of the table object such that all information is neatly displayed.

To add another identifier to the ‘UnitTransportCost’ table, execute the follow- ing actions inEditmode:

 select the table by clicking on it,  press the button on the toolbar (or alternatively, use the right mouse) to access the properties dialog box,  select the contents tab (see Figure6.3),  press the Add button,  select the identifier ‘Supply(p)’, press the Next button, and then press the Finish button, and  back on the contents tab, press the OK button.

Figure 6.3: Table contents tab

You can add demand data to the table in the same way as you added the supply data. The resulting table is shown in Figure6.4.

Chapter 6. Building a Page

Creating a bar chart is essentially the same process as creating a table. The following steps summarize the process for the parameter ‘Supply’:

 on the toolbar,press the new-bar-chart button  position the mouse cursor, and drag to form the new bar chart,  select the parameter ‘Supply(p)’ in the identifier selection wizard,  press the Next button, and then the Finish button.

You can then create a bar chart for the demand data in the same way as you created the bar chart for the supply data. Your intermediate page should now look like the one in Figure6.5.

Figure 6.5: Intermediate input-output page

Presenting the output data

A composite table inAimmsis like a relational database table: the first columns contain indices, and the remaining columns contain identifiers defined over these indices. Creating a composite table containing only the optimal solution is similar to creating a standard table or a bar chart, and requires the following actions:

 press the button on the toolbar to create a new composite table,  draw the table using the mouse,  select the variable ‘Transport(p,c)’ in the identifier selection wizard to indicate which index values must be displayed,

 press the Next button, and then the Finish button.

Yet another way to display the solution is by means of a stacked bar chart:

 create a standard bar chart displaying the variable ‘Transport(p,c)’.  select the ‘bar chart’ tab in the properties dialog box as illustrated in Figure6.6),  instead of the default ‘Overlapping’ option, select the ‘Stacked Bar’ op- tion, and  press the OK button.

Figure 6.6: Bar chart property dialog box

The scalar object is designed to display scalar values. To display the optimal solution value in a scalar object you should do the following:

 press the button on the toolbar to create a scalar object,  draw the scalar object using the mouse,  select the scalar variable ‘TotalTransportCost’ in the identifier selection wizard, and  press the Finish button.

Finishing the page

Chapter 6. Building a Page

Designing a professional looking graphical end-user interface is not a trivial ac- tivity, and is beyond the scope of this tutorial. Nevertheless, you will be asked to spend a little time building a nice looking page as illustrated in Figure6.11 at the end of this section.

One item on this page is a button designed to trigger the solution of the ‘Least- CostTransportPlan’ mathematical program. To create such a button, you need to execute the following actions:

 press the button on the toolbar to create a new button, and draw the button using the mouse,  enter the quoted string “Solve Beer Transport” as the title of the button, and  select the actions tab.

The action to be specified is thatAimms”runs”) a procedure. Inexecutes (i.e. this example, the procedure is ‘MainExecution’. Continue with the following steps:

 select ‘Run’ as the action to add,  press the Add button,  select option ‘Procedure’,  press the enabled wizard button ,  select the procedure ‘MainExecution’,  press the Finish button, and accept by pressing the OK button.

The completedActionstab of theButton Propertiesdialog box is displayed in Figure6.7. Note that the button can only be used to solve the model when the page is put intoUsermode by pressing theUser Modebutton .

The resulting input-output page (see Figure6.11) contains three text objects. The title text ‘Beer Transport’ can be created as follows:

 select theTextcommand from theObjectmenu (see Figure6.8), and draw a rectangle using the mouse,  specify ‘Beer Transport’ as the static text on thetexttab of theText Propertiesdialog box,  select ‘Center’ from the ‘Alignment’ drop-down list (see Figure6.9) ,  select theFonttab of theText Propertiesdialog box, and  press the Add button.

You can now specify and name the appropriate font, and thereby complete the text object.

 select ‘Bold’ as theFont Style, and ‘20’ as the ‘Font Size’,  press the OK button,  specify ‘Title’ as the name of the new font,  press the OK button to return to theText Propertiestab,  again, press the OK button to leave theText propertiesdialog box,

The other two text objects displaying the text ‘Input Data’ and ‘Output Data’ are created in the same way. Instead of using the newly constructed ‘Title’ font, you should create a second custom font, named ‘Header’ font, of size ‘14’. The font tab of theText Propertiesdialog box is displayed in Figure6.10.

Figure 6.10: The font tab of the text properties dialog box

The page is completed by adding two rectangles to emphasize that there are two groups of objects representing input data and output data. Assuming that you have rearranged and resized the objects to fit neatly together, you can draw the rectangles as follows:

 select theRectanglecommand from theObjectmenu, and  draw the rectangle using the mouse.

Your page should now look like the one in Figure6.11.
