AATP
type: Class
comment: When scarce ATP quantities are allocated to different customer classes or customers, the resulting supply reservations are called allocated ATP (AATP) quantities.

ATP
type: Class
comment: The part of the inventory and projected supply that can be used to fulfill customer orders is called ATP.

Activity
type: Class
comment: An activity is something carried out over a specific time interval.

Batch Interval
type: Class
comment: This is the time span for which arriving orders are collected to derive for all of them jointly a first promised delivery date.
subclass of: Time Interval

Best Promised Delivery Date
type: Class
comment: 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.
subclass of: Date

Demand Class
type: Class
comment: This concept is used for dividing the total forecast for a given product into several priority classes.

Demand Priority
type: Class
comment: This concept is used to describe the different importance level of a demand. The demand priority can be assigned independently from the demand class.

Last Promised Delivery Date
type: Class
comment: This is the last commitment the supplier has given to the customer
subclass of: Date

Order Position
type: Class
comment: 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.

Planning Period
type: Class
comment: 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.
subclass of: Time Interval

Planning Window
type: Class
comment: Planning in supply chains is associated with a planning window which is formed by a set of consecutive planning periods.
subclass of: Time Interval

Split Order
type: Class
comment: 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.
subclass of: Order

Allocation Plan
type: Class
comment: An allocation plan is a special plan, which deals with assigning ATP quantities to a customer or a customer class.
subclass of: Plan
disjoint with: Master Plan

Assemble to order (ATO)
type: Class
comment: 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.
subclass of: Production Strategy

Bill of Material (BOM)
type: Class
comment: 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.

Complete Delivery
type: Class
comment: The normal case is that an order is completely delivered.
subclass of: Delivery Concept

Confirmed Delivery Date
type: Class
comment: 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.
subclass of: Date

Customer
type: Class
comment: A customer can place orders. He raises a demand for a specific product or service. Internal and external customer demand can be distinguished.

Customer Class
type: Class
comment: The set of all customers is divided into different priority classes or segments based on certain criteria like profitability or importance of customer.

Customer Order
type: Class
comment: This is an order that is initiated by a customer.
subclass of: Order
disjoint with: Replenishment Order

Date
type: Class
comment: 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.

Delivery Concept
type: Class
comment: 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.

Delivery Date
type: Class
comment: This is the point in time when the customer received the requested order.
subclass of: Date

Demand
type: Class
comment: 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.

Engineering Lot
type: Class
comment: 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.
subclass of: Lot
disjoint with: Productive Lot

Firm Order Demand
type: Class
comment: This is a special demand class that is used for demand that is required to fulfill already committed/accepted orders.
subclass of: Demand Class

First Promised Delivery Date
type: Class
comment: Initially, the FPD is set for an order delivery within the online order confirmation process.
subclass of: Date

Forecasted Demand
type: Class
comment: This is a special demand class that is used for the projection of future demand.
subclass of: Demand Class

HasBatchingInterval
type: DatatypeProperty
comment: This is the time span for which arriving orders are collected to derive for all of them jointly a first promised delivery date.
domain: Order
range: Literal
sub property of: topDataProperty

HasDemandPriority
type: DatatypeProperty
comment: This concept is used to describe the different importance level of a demand. The demand priority can be independently assigned from the demand class.
domain: Demand
range: Literal
sub property of: topDataProperty

Inventory Replenishment Demand
type: Class
comment: This is a special demand class that is used for replenishment of safety stock.
subclass of: Demand Class

Lot
type: Class
comment: 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.

Make to order (MTO)
type: Class
comment: This is a strategy where production is initiated to fulfill specific customer orders. This strategy is characterized by an order-driven production.
subclass of: Production Strategy

Make to stock (MTS)
type: Class
comment: 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.
subclass of: Production Strategy

Master Plan
type: Class
comment: 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.
subclass of: Plan

Order
type: Class
comment: An order contains at least one order position. An order has an order type and is associated to demand

Order Delivery Plan
type: Class
comment: 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.
subclass of: Plan

Order Promising
type: Class
comment: 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.
subclass of: Planning

Partial Delivery
type: Class
comment: 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.
subclass of: Delivery Concept
disjoint with: Split Delivery

Period
type: Class
comment: The concept period displays the sub unit of the planning horizon.
subclass of: Time Interval

Plan
type: Class
comment: 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.

Planning Purpose
type: Class
comment: The planning purpose describes a set of criteria that influence other concepts, e.g. product aggregate.

Product
type: Class
comment: 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.

Product Aggregate
type: Class
comment: 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.

Product Hierarchy
type: Class
comment: The concept characterizes the top-down and bottom-up relationship between different product aggregates. It organizes the product aggregates according to defined criteria.

Production Strategy
type: Class
comment: 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.

Productive Lot
type: Class
comment: 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.
subclass of: Lot

Promised Delivery Date
type: Class
comment: 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.
subclass of: Date

Replenishment Order
type: Class
comment: 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.
subclass of: Order

Requested Delivery Date
type: Class
comment: The RDD is the point in time when the customer wants to get the order.
subclass of: Date

Route
type: Class
comment: 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.

Split Delivery
type: Class
comment: It can be allowed that order positions of an order are delivered in several portions.
subclass of: Delivery Concept

Supplier
type: Class
comment: A Supplier fufills a demand for a specific product or service.

Supply
type: Class
comment: 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.
