When scarce ATP quantities are allocated to different customer classes or customers, the resulting supply reservations are called allocated ATP (AATP) quantities.
The part of the inventory and projected supply that can be used to fulfill customer orders is called ATP.
An activity is something carried out over a specific time interval.
This is the time span for which arriving orders are collected to derive for all of them jointly a first promised delivery date.
This is the best delivery date the supplier ever promised to the customer. It represents the best delivery date the supplier submitted to the customer. Thus every later commitment or delivery is a de-commitment from the supplier.
This concept is used for dividing the total forecast for a given product into several priority classes.
This concept is used to describe the different importance level of a demand. The demand priority can be assigned independently from the demand class.
This is the last commitment the supplier has given to the customer
An order position refers to a product specification, a product quantity, and a desired delivery date. Each order position has a status and belongs to an order.
A planning period is a specific DateTimeInterval from the time ontology (Time Ontology 2020). It belongs to a planning window. It has a temporal duration.
Planning in supply chains is associated with a planning window which is formed by a set of consecutive planning periods.
This is an order that results from a split delivery. When an order position of an order is delivered in several portions, each portion starting from the second one is considered as a separate suborder which is called scheduled order position. The original order also exists after the split.
An allocation plan is a special plan, which deals with assigning ATP quantities to a customer or a customer class.
In the case of ATO, products are produced forecast-driven until the point right before it comes to the assembly. Starting from there, the production continues based on a customer order.
A BOM describes components or rather semi-finished products that are part of the finished product. Substitution, often associated with binning, is based on the possibility that alternative items might be used to finish a process step. This leads to the notion of alternative BOMs.
The normal case is that an order is completely delivered.
The CDD is the committed date for order delivery that is communicated to the costumer. It depends on the communication strategy between manufacturer and customer. For instance, the CDD is the PDD if order repromising takes place in the same frequency as the update interval of the CDD.
A customer can place orders. He raises a demand for a specific product or service. Internal and external customer demand can be distinguished.
The set of all customers is divided into different priority classes or segments based on certain criteria like profitability or importance of customer.
This is an order that is initiated by a customer.
The availability date defines the point in time when the supply is available to the customer. It can be distinguished between different availability dates. Not all availability dates are communicated to the customer.
The deliver concept defines the terms and conditions for delivering an order to the customer. Especially partial and split delivery has to be taken into account.
This is the point in time when the customer received the requested order.
Demand is a production request for a specific product or service that can have different triggers. Either demand exists explicitly in form of customer orders or implicitly as expected customer need that have to be fulfilled by the semiconductor supply chain.
An engineering lot requires additional process development efforts and special attention during the production flow. Engineering lots have various functions, thus several engineering lot types can be differentiated.
This is a special demand class that is used for demand that is required to fulfill already committed/accepted orders.
Initially, the FPD is set for an order delivery within the online order confirmation process.
This is a special demand class that is used for the projection of future demand.
This concept is used to describe the different importance level of a demand. The demand priority can be independently assigned from the demand class.
This is a special demand class that is used for replenishment of safety stock.
A lot is a set of wafers, substrates or modules that travel together through the FE or BE fab in order to fulfill a certain order.
This is a strategy where production is initiated to fulfill specific customer orders. This strategy is characterized by an order-driven production.
This is a strategy where production is driven by the replenishment of inventories at specific locations. Products are produced forecast-driven until they are completely finished in the case of MTS.
A master plan is a specific plan which determines which quantity resulting from confirmed orders and from forecasted demand should be completed in which location in which period of the planning horizon. Moreover, outsourcing decisions have to be represented in master plans.
An order contains at least one order position. An order has an order type and is associated to demand
This is the result of the order promise or repromise process for different sets of orders taking into account an allocation policy and the supply and allocation situation. Different order promising variants can be distinguished, for instance online order promising, batch order promising, and hybrid order promising. The same is true of repromising.
This concept describes the process to promise an order considering allocation policy as well as supply and allocation situation. The order promising can be distinguished between different variants, for instance online order promising and batch order promising.
It can be allowed that only parts of an order position of an order are delivered. Therefore, the customer is willing to waive parts of quantity belonging to an order position.
The concept period displays the sub unit of the planning horizon.
A plan is an activity specification with an intended purpose. Planning is an activity with the purpose to determine a plan. Planning is associated with goals, in the present situation represented by objective functions to be optimized.
The planning purpose describes a set of criteria that influence other concepts, e.g. product aggregate.
A product is a good that fulfills a prescribed set of requirements (for instance, form, fit, and function). A set of alternative BOMs might be associated with each product. The manufacturing process is complicated by binning and substitution (in production). Binning refers to the process that an item can become one of several products based on tested levels of performance, for instance, speed.
The concept product aggregate is used to group different products based on certain criteria. The grouping criteria depend on the planning purpose (e.g. controlling, production). It is a certain view (external or internal) on a set of products.
The concept characterizes the top-down and bottom-up relationship between different product aggregates. It organizes the product aggregates according to defined criteria.
The production strategy determining which portions of a supply chain should operate in make to stock (MTS) mode, where production is driven by the replenishment of inventories at specific locations, and which in make to order (MTO) mode, where production is initiated to fulfill specific customer orders. The production strategy is related to the question where the customer order decoupling point (CODP), also referred to as the push-pull interface (or boundary) has to be placed. The CODP denotes the point in the supply chain where material is dedicated to a specific customer order to the degree that it cannot be used for another.
A productive lot is created to fulfill a customer demand. The production process is carried out as it is defined during the production development phase.
This is the date for which eventually partial order delivery is confirmed. The PDD date can be changed over time. Within the repromising process there are typically different PDDs available.
This is an order that is initiated by an internal request of the semiconductor manufacturer to produce the order according to a MTS strategy. The replenishment order can be divided into different sub order types, depending on the purpose of order creation.
The RDD is the point in time when the customer wants to get the order.
The term route can be considered on different levels. In the present situation, a route is associated with a product and describes its production flow on the production network level.
It can be allowed that order positions of an order are delivered in several portions.
A Supplier fufills a demand for a specific product or service.
This is the total amount of specific products that is available to customers. Supply has the dimensions quantity, time, location, product, including aggregation of all dimensions. Supply is defined as inventory or plan replenishment.
