Parameters Tab
The Parameters tab displays the parameters that are used by the size profile generation algorithm. The escalation path is used to cluster data and estimate profiles at different levels (that is, merchandise/location or merchandise/location/attribute) and find the optimal size profiles that best represent the expected demand pattern and is most robust to stock out periods, imbalanced stock across sizes and other factors. When a size profile at a given level of the escalation path does not meet the post-processing criteria, it automatically gets rejected and the size profile associated with a higher level is examined. This process continues until a valid size profile is fond at one of the levels along the escalation path.
The lowest level of the escalation path in a run defines the level of the profiles generated in that run. For example, if the escalation path consists of department-region, department-location, subclass-region, and subclass-location, the size profiles will be generated at subclass-location level, that is one profile for each subclass/location/size range. In addition, for all runs at any level, size profiles will also be generated at the lowest level (style-color/location).
The parameters of the size profiles estimation algorithm fall into two categories: pre-processing and post-processing.
You can edit the values for these parameters, as shown in Figure 8-6. The default values of the parameters are defined in SPO_DFLT_PARAMETER. You can modify the default values using the Manage System Configuration screen under the Control & Tactical Center. The table below shows the name, description, and default value of the parameters.
