Optimization Sourcing Policies Explained

Optimization (NEO) will read from all 5 of input tables in the Sourcing section of Cosmic Frog.

• Customer Fulfillment Policies
• Replenishment Policies
• Procurement Policies
• Production Policies
• Supplier Capabilities

We are able to use these tables to define the sourcing logic that describes costs and where a product can be introduced into the network through production at a Facility (Production Policies) or by way of a Supplier (Supplier Capabilities). We can also define additional rules around how a product must be sourced using the Max Sourcing Range and Optimization Policy fields in the Customer Fulfillment, Replenishment, and Procurement Policies tables.

Max Sourcing Range

The Max Sourcing Range field can be used to specify the maximum flow distance allowed for a listed location / product combination. If flow distances are not specified in the Distance field of the Transportation Policies table, a straight-line distance will be calculated based on the Origin / Destination geocoordinates. This will take into account the Circuity Factor specified in the Model Settings as a multiplication factor to estimate real road distances. Any transportation distances that exceed the Max Sourcing Range will result in the arcs being dropped from consideration.

Optimization Policy

There are 4 allowable entries for Optimization Policy. For any given Destination / Product combination, only a single Optimization Policy entry will be supported meaning you can not have one source listed with a policy of Single Source and another as By Ratio (Auto Scale).

To Optimize

This is the default entry that will be used if nothing is specified. To Optimize places no additional logic onto the sourcing requirement and will use the least cost option available.

Single Source

For the listed destination / product combination, only one of the possible sources can be selected.

By Ratio (Auto Scale)

This option allows for sources to be split by the defined ratios that are entered into the Optimization Policy Value field. All of the entries into this Policy Value field will be automatically scaled, and the flow ratios will be followed for all inbound flow to the listed destination / product combination.

For example, there are 3 potential sources for a single Customer location. There is a flow split enforced of 50-30-20 from DC_1, DC_2, DC_3 respectively. This can be entered as Policy Values of 50, 30, 20

The same sourcing logic could be achieved by entering values of 5, 3, 2 or even 15, 9, 6. All values will be automatically scaled for each valid source that has been defined for a destination / product combination.

By Ratio (No Scale)

Similar to the Auto Scale option, By Ratio (No Scale) allows for sources to be split by the defined ratios entered into the Optimization Policy Value field. However, no scaling will be performed and the Optimization Policy Value fields will be treated as absolute sourcing percentages where an entry of 50 means that exactly 50% of the inbound flow will come from the listed source.

For example, there are 3 possible sources for a single Customer location and we want to enforce that DC_1 will account for exactly 50% of the flow while the remainder can come from any valid location. We can specify that DC_1 will have a Policy Value of 50 while leaving our other options open for the model to optimize.

If Policy Values add up to less than 100 for a listed destination / product combination, another sourcing option must be available to fulfill the remaining percentage.

If Policy Values add up to more than 100 for a listed destination / product combination, the percentages will be scaled to 100 and used as the only possible sources.
