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)

01Volume/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

02Singular/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:

$DP_{p,c}={\frac {\sum _{p,c}(DP)}{count_{p,c}(singularcases)}}$

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:

$DP_{p,c}={\frac {\sum _{p,c}(DP)}{count_{p,c}(singularcases)}}$

whereas p is determined by the first confirmed date
