Delivery performance (DP) is a broadly used standard KPI measurement in supply chains to measure the fulfillment of a customer's demand to the wish date.
[1] Following the nomenclature of the DR-DP-Matrix three main approaches to measure DP can be distinguished: If (
) Else Demand:= customers wish c:= product identifier p:= Time period e.g. a day, a week, a month ...
The cumulation over a period and a group of product identifiers c is done as follows:
whereas p is determined by demand period To fit to the needs of the environment, the granularity of a singular case (
In general a singular case is described by a n-Tuple consisting of a set of the following order and delivery details: arrival date = delivery date + transit time By cumulating the results of singular cases over a certain period p and, if necessary, additional criteria c (e.g. customer, product, ...) the delivery performance is calculated as follows:
{\displaystyle DP_{p,c}={\frac {\sum _{p,c}(DP)}{count_{p,c}(singularcases)}}}
whereas p is determined by the arrival date arrival date = delivery date + transit time By cumulating the results of singular cases over a certain period p and, if necessary, additional criteria c (e.g. customer, product, ...) the delivery performance is calculated as follows:
{\displaystyle DP_{p,c}={\frac {\sum _{p,c}(DP)}{count_{p,c}(singularcases)}}}
whereas p is determined by the first confirmed date 0%≤
