For very complex rules, an external file might be used to implement them in Metis Smart Modeling. The purpose of this rule type is to allow the development of algorithms which may not be handled in Metis. The file linked to such rule should a compiled program which can be started by providing at least one parameter and which returns '''only one''' value.

| + | In the “Modeling” menu, make sure that the “Rules” sub-menu has been selected. | ||
| + | On the left, in the “Groups of rules” dropdown list, select “D-Basic Hardware.” | ||
| + | Click on add. A window opens where the new rule will be created. | ||
| + | In the “Type” field, select “External” from the dropdown list. In the “comment” field, enter a name for the rule. For example, “Total Service Time.” | ||
| + | The goal of this example rule is to provide two inputs to an external program. The program will then sum up the value of the inputs and provide the output to a variable. | ||
| + | Click on the add button near the “input” field. A window opens where it is possible to select positions, variables, and attributes. Select “Attributes.” | ||
| + | Select “Installation time” from the list and confirm. | ||
| + | Repeat the same steps, but this time select “Project management” from the list. | ||
| + | Note: It is very important that the order in which the parameters are listed in the table is the same as within the external program. | ||
| + | Click on the add button near the “Output” field. The same window from before opens, but it is only possible to select positions or variables. In this example a position is added. Select “Variables.” | ||
| + | Search for the variable “$Service.” Select it and then confirm. | ||
| + | In the “Input” section, click on the icon next to the “External File Name” field. | ||
| + | A window opens. Click on the add button. The “select a file…” window opens. | ||
| + | For this example the file “ADD.exe” is added. Make sure that the “Add.exe” file is selected and then click on confirm to continue. | ||
| + | To test this new rule, click on the “test” button.The test window opens. | ||
| + | In the “test value” field for “Installation Time” enter “12.” For “Project Management,” enter “4.” | ||
| + | Click on the test button. The results appear below. The external program has summed up both input values. | ||
| + | Close the test window. Click on confirm to save the rule. It now appears in the list of rules. | ||
