Cumulative quantities (logistics)
Open-knowledge reference entry
Cumulative quantities are a concept in logistics that involves adding up required materials quantities over a defined time-window that can be drawn as a 'cumulative curve'. This concept is applied in serial production and mainly used in the automotive industry to plan, control and monitor production and delivery. The concept is sometimes called 'cumulative production figures principle' (CPGP).
Closed-loop-cycle
The concept of cumulative quantities (CCQ) uses the feedback mechanism of a closed loop, which can be found in industrial, engineering and electronic systems. The target requirements are summarized for each time-interval and compared with the actual values for closed-loop control. Positive cumulative deviation for a certain time-interval requires no further order, while negative deviations require a new order. To "calm" production and material flow, upper and lower tolerance boundaries are defined, and only if these boundaries are violated is a renewed order.
To check the entire production and material flow, 'reporting limits' can be defined at a chosen counting point, and if a limit is exceeded, a concerned 'alert' is issued. The logistics staff has to explain the reason for the 'alert'. If the reason is correct and traceable, no further action is needed.
The public source identifies “Cumulative quantities (logistics)” as open-knowledge reference entry. This brief keeps that definition visible, then builds a research path around Cumulative, quantities and logistics.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Cumulative quantities (logistics)”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 27, 2025. The linked authority identifier is Q56291761. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
