Create a product configuration model
This procedure outlines the steps to create a product configuration model and to enter essential details, such as attributes and subcomponents.
Create a product model
To create a product model, follow these steps:
Go to Product information management > Products > Product configuration models and then select New.
Enter values in the Name and Description fields.
Select an option in the Solver strategy field. The solver strategy dictates how the system handles constraints in a constraint-based product configuration model, influencing its overall performance.
Enter a value in the second Name field. The root component represents the product configuration model, but you can also use it in other product models.
Select OK.
Add attributes
To add attributes, follow these steps:
Expand the Attributes FastTab and then select Add.
Enter a value in the Name field.
Enter a value in the Solver name field.
Enter a Description.
Select an Attribute type. This selection determines which values are available for the attribute.
Select Save.
Add subcomponents
To add subcomponents, follow these steps:
Expand the Subcomponents FastTab and then select Add.
Enter values in the Name, Solver name, and Description fields.
Select a component in the Component field.
Select Save.
Select BOM line details to allow users to select the required properties for the subcomponent.
Select a value in the Item number field.
Set the Calculation field to Yes to ensure that the system includes the product when it runs a cost calculation for the product.
Select the Setup tab.
Set the checkbox next to the Quantity field and then enter a number. This step determines how much of this product is consumed in the configured product.
Set the checkbox next to the Per series field and then enter a number.
Select OK.
Solver strategy for production configuration
A product configuration model can be formulated as a Constraint satisfaction problem (CSP). Microsoft Solver Foundation (MSF) provides two types of solver strategies to solve the CSPs that can be used from product configuration models.
These solver strategies rely on heuristics (rules of thumb), which are used to determine the order in which the variables of the CSPs are considered when the problem is being solved. Heuristics can significantly affect performance when a problem or class of problems is being solved.
In Supply Chain Management, the solver strategy for product configuration models determines which solver is used with heuristics. The Default, Minimal domains first, and Top-down strategies use the two solvers from MSF, whereas the Z3 strategy uses the Z3 solver.
Product information management > Products > Product configuration models > New
Customer implementation studies have shown that a change in the solver strategy for a product configuration model can reduce the response time from minutes to milliseconds. Therefore, it's worth the effort to try different solver strategies to find the most efficient strategy for your product configuration model.
Change settings for the solver strategy
To change settings for the solver strategy, on the Product configuration models page, on the Action Pane, select Model properties. Then, in the Edit the model details dialog box, select a solver strategy.
Currently, there is no logic that automatically detects which solver strategy will be the most efficient strategy for constraint-based product configuration. Therefore, you must try each solver strategy individually.
The following table provides recommendations about the solver strategy that you can use in various scenarios.
Solver strategy | Use the strategy in this scenario |
---|---|
Default | This strategy has been optimized to solve models that rely on table constraints. Customer implementation studies have shown that Default is the most efficient strategy in scenarios where table constraints are used extensively. |
Minimal domains first | The Minimal domains first and Top-down strategies are closely related. Customer implementation studies have shown that the Top-down strategy outperforms the Minimal domains first strategy. However, the Minimal domains first strategy is kept in the product for backward compatibility. Both solver strategies have been shown to be more efficient at solving models that contain several arithmetic expressions where no table constraints are used. However, in some cases, the Default strategy outperforms these two strategies. Therefore, remember to try each strategy. |
Top-down | The Minimal domains first and Top-down strategies are closely related. Customer implementation studies have shown that the Top-down strategy outperforms the Minimal domains first strategy. However, the Minimal domains first strategy is kept in the product for backward compatibility. Both solver strategies have been shown to be more efficient at solving models that contain several arithmetic expressions where no table constraints are used. However, in some cases, the Default strategy outperforms these two strategies. Therefore, remember to try each strategy. |
Z3 | We recommend that you use the Z3 strategy as the default solver strategy. If you're concerned about performance and scalability, you can evaluate the other strategies. |
