The **Number of Fills** for Capital Intensive and Low Demand Service Parts is the `quantity of demand`

that we expect to be able to service given the amount of inventory we have decided to hold for the part.

The **Number of Fills** is calculated using the Demand Distribution for the part.

# Example

Suppose we think mean demand is 3 units.

We are considering stocking 4 units using an S, S-1 Inventory Policy.

The **Number of Fills** will be the sum of the probabilities times `mean demand`

or `(probability(1) + probabillity(2) + probability(3) + probility(4)) * 3`

.

Lets assume that the Demand Distribution is a six sided dice.

In this case the **Number of Fills** is `mean demand`

times the probability sum or `(1/6 + 1/6 + 1/6 + 1/6)*3`

or `2/3 * 3`

or `2`

.

So If we stock stock 4 units we expect to fufill 2/3 of the expected demand.
