Custom Objectives Sheet

This sheet allows you to define any custom objectives specific to your analysis needs.

How to use Custom Objectives?

AIMMS SC Navigator contains a set of pre-defined objectives that are used to optimize the supply chain network. However, there may be cases where you want to define your own custom objectives specific to your analysis needs. For instance, Carbon Emissions, Tariffs, Taxes, and Duties are examples of custom objectives that can be defined on this sheet. Once you have defined your custom objectives in this sheet, the generated template will include the necessary input columns for you to enter data related to these custom objectives in other sheets of the template. The model will then use this data to calculate the total cost or revenue associated with each custom objective, which can be included in the overall model objective function.

How it affects the model

A column is generated in the template for each custom objective defined in the Custom Objectives sheet and each cost attribute (Name is of the form <Custom Objective Name>_<Attribute Name>). The model will use the data entered in the input columns to calculate the total cost or revenue associated with it. This total cost or revenue can then be included or limited in the overall model, based on the settings defined in this sheet.

The attributes on this sheet

Purpose: Define custom objectives and their details for the analysis.
Instructions: Enter custom objectives and define the following data for each custom objective:

  1. Type: Custom objective is Cost or Revenue type

  2. UOM: Unit of measurement for this Custom Objective.

  3. Include in Model Objective: Indicates whether this Custom Objective is to be included in the Model Objective by default.

  4. Scaling Factor: A factor that converts the Custom Objective from its natural unit to the base monetary unit of your model.

  5. Refundable with Limit: Possible values 0, 1 or 2. 0: No limit on the refundable part (Payable = total debits - total credit). Create a cost type and a revenue type custom objective to model this. 1: Refundable up to a zero balance, you never get any money back (Payable = max{0, total debit - total credit}). 2: Refundable up to a zero balance, after you will pay a penalty for the extra credits (Payable = total debit - total credit).

  6. Risk: Possible values 0, 1: Indicate if this custom objective is included in automated risk analysis.

  7. Percentage Based: Possible values 0, 1: Indicates if the Custom Objective is Percentage Based, so it will be used to model tariffs.
