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. Following the nomenclature of the DR-DP-Matrix three main approaches to measure DP can be distinguished: * DP_{T}^{V} * DP_{D}^{S} * DP_{T}^{S} :Type of measurement: volume (V)/singular(S) :Type of view: on time (T)/ delivery (D)
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. Following the nomenclature of the DR-DP-Matrix three main approaches to measure DP can be distinguished: DP_{T}^{V} DP_{D}^{S} DP_{T}^{S} Type of measurement: volume (V)/singular(S) Type of view: on time (T)/ delivery (D)
Volume/on time
Formula
If ( (Demand_{p,c} + Backlog_{p-1,c})>0 ) DP_{T}^{V} = \frac{Delivered_{p,c} + Predelivery_{p-1,c}}{Demand_{p,c} + Backlog_{p-1,c}} Else NULL 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: DP_{p,c} = \frac{\sum_{p,c}(DP_{T}^{V})}{count_{p,c}(DP_{T}^{V}<>NULL)} whereas p is determined by demand period
Singular/delivery and singular/on time
Singular case definition
To fit to the needs of the environment, the granularity of a singular case ( DP_{*}^{S} ) has to be defined. In general a singular case is described by a n-Tuple consisting of a set of the following order and delivery details: order number customer identifier product identifier wish date of customer confirmed date of supplier ship to information delivery date delivery note number
Formula
DP_{D}^{S} After a singular case has been delivered to the customer its DP is measured as follows: If (wish date = arrival date) then DP singular case =1 else DP singular case =0 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: DP_{p,c} = \frac{\sum_{p,c}(DP)}{count_{p,c}(singular cases)} whereas p is determined by the arrival date DP_{T}^{S} After a period has elapsed all singular cases with wish date within period are considered and their DP is measured as follows: If (wish date = arrival date) then DR singular case =1 else DR singular case =0 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: DP_{p,c} = \frac{\sum_{p,c}(DP)}{count_{p,c}(singular cases)} whereas p is determined by the first confirmed date
Result
0%≤ DP_{T/D}^{S/V} ≤100%
