(ASR) equilibrium
Any batch that is not equal to actual demand.
Acronym of Actively Synchronized Replenishment
The point of indifference between the investment in adding stock positions (typically component
parts) and the lead-time inventory compression resulting from that investment (typically parent
items).
A qualified cumulative lead time defined as the longest unprotected/unbuffered sequence in a bill of
material.
A planning calculation to determine the planning status of a stocked item. The equation is on-hand +
on-order stock (also referred to as open supply) –unfulfilled qualified actual demand. If the available
stock equation yields a position in the green zone of a buffer, then typically no planning action is
required.
The amount of remaining buffer, typically expressed as a percentage.
A globally managed group of parts with similar lead time, variability, control, and order management
characteristics.
A stratification layer within a stock buffer. Typically, buffer zones are colorcoded with red, yellow,
and green assignments.
The process of creating supply orders based on the available stock equation and decoupled
explosion.

for red zone penetrations and out-of-stock situations.
Acronym of Demand Driven Material Requirements Panning
An innovative method to plan materials that enables a company to build more closely to actual
market requirements.
The cessation of bill of material explosion at any buffered/stocked position.
Buffer levels that are adjusted either automatically or manually based on changes to key part traits.
execution horizon
The life cycle of orders from the time the order is created and/or released to the time it is closed.
horizon d'exécution
green zone
The top layer of a replenished and replenished override buffer. If available stock is in this zone, then
no additional supply is created.
Acronym of Lead-Time-Managed part
A critical nonstocked part that will have special attention paid to it over its execution horizon.
Typically, LTMparts are critical, long-leadtime components that do not have sufficient volume to
justify stocking. A portion of the lead time of the part (typically 33 percent) will have a three-zoned
warning applied to it. That portion is typically divided into three equal sections.

composant à délai critique
An alert/warning generated by an LTM part. An alert will be triggered whenever the part enters a
alerte sur délai
different time zone from its buffer. Green is the first alert to be encountered, followed by yellow and
then red.
The zone associated with the percentage of lead time that provides the definition for lead-time
zone d'alerte sur délai
alerts. The LTMalert zone has three equal sections colorcoded green, yellow, and red.
The lead time that will allow an increase in price or the capture of additional business either through
existing or new customer channels.
An alert generated by the earliest occurrence of a negative on-hand balance within at least one
ASRLT where open supply receipt is due after required demand date.
All parts that are not stocked.
A method to adjust buffers based on the number and severity of specific occurrences in predefined
fixed interval.
The percentage of the red zone used by buffer status alerts in order to determine a yellow or red
color designation.

red zone
red zone base
Adefined future time frame used to qualify order spikes in combination with an order spike
threshold. Typically, order spike horizon is set to one ASRLT.
A defined amount used to qualify order spikes in combinations with an order spike horizon. Typically,
the order spike threshold will be expressed as a percentage of the total red zone (or min value) of a
part’s buffer.
Acronym of Over Top of Green
A situation in which either available stock or on-hand stock is over the top of defined green zone,
indicating an excessive inventory position.
Manipulations to the buffer equation that affect inventory positions by raising or lowering buffer
levels and their corresponding zones at certain points in time. Planned adjustments are often based
on certain strategic, historical, and business intelligence factors.
horizon de demande soudaine
An alert generated by projected on-hand positions over a part’s ASRLT based on on-hand, open
supply, and either actual demand or ADU.
The demand portion of the available stock equation comprised of qualified order spikes, past-due
demand, and demand due today.
A quantity of combined daily actual demand within the order spike horizon and over the order spike
threshold.
reduce operations in anticipation of declining demand. For example, a toy store may ramp down its
operations by buying fewer toys from its wholesaler immediately after the Christmas season, when
people are less likely to buy toys in large quantities.
Manipulations to the buffer equation that affect inventory positions, lowering buffer levels and their
corresponding zones at certain points in time. Ramp-down adjustments typically are used in part
deletion.
