Enterprise Integration and Communications Systems

Real Time
(1) Pertaining to the actual time during which a physical process transpires. (2) Pertaining to computations performed while the related physical process is taking place so that results of the computation can be used in guiding the physical process.
Real Time System
Always provides responses (both periodic, time-initiated responses and input or interrupt driven responses) within a specified window of time. The time is determined by the time constant of the dynamic process. Example time constants for external processes are milliseconds for machining or electric power systems, seconds for flow processes, minutes for thermochemical compositions and weeks for social/economic processes.
Receipt of Finished Goods
Physical acceptance of an item into a stocking or storage location. This also refers to the transaction reporting of this activity. [APIC]- In this context, this is a receipt for accepting finished goods from WIP (Work in Process).
Receipt Stockroom
The physical acceptance of an item into a stocking or storage location. This also refers to the transaction reporting of this activity. [APIC].
Receipt WIP
This is the physical acceptance of an item into a stocking or storage location. This also refers to the transaction reporting of this activity. [APIC].
Reference Architecture
Non-industry specific reference base from which to construct models of a particular enterprise. Contains both Building Blocks and Guidelines. [CIM-OSA].
Reference Model
A standard definitive document or conceptual representation of a system or process.
(1) An interaction between entities. Usually expressed as verbs in English. (2) A named business association between occurrences of one or more entity types which provides some relevant information value.
Relationship Type
Is a classification of relationships based on certain criteria. The numerical relationship between two entities is called the cardinality.
Relay Ladder Logic
A control language for programming Programmable Logic Controllers.
Release for Shipment
Quality, location, destination of product to be shipped.
Released Order
Within MRP, open production orders and open supply orders are considered as released, are assumed to be available on their due dates, and will be treated as part of the available inventory during the netting process for the time period in question. [APIC].
The actual degree of dependability with which the equipment performs (note: actual, versus hoped-for). May be expressed in failures per 100,000 hours.
A device that amplifies or regenerates data signals in order to extend the distance between data stations.
Resource Build Schedule
A schedule of the activities needed to make, install or procure production resources, such as equipment, facilities and tools (excluding material), which are needed to support production.
Resource Definition
The layout, requirements, configuration, design and capacity of resources needed to perform a particular function or operation.
Resource Plan
Long-range resource planning is based on the production plan, the plan for the long-term capacity needs out to the time period necessary to acquire gross capacity additions, such as a major factory expansion. [APIC].
Resource Requirements Planning
The process of converting the production plan and/or the master production schedule into the impact on key resources, such as man hours, machine hours, storage, standard cost dollars, shipping dollars and inventory levels. Product load profiles or bills of resources could be used to accomplish this. The purpose of this is to evaluate the plan prior to attempting to implement. It is sometimes referred to as a rough-cut check on capacity. Capacity requirements planning is a detailed review of capacity requirements.
Resource View
Describes an enterprise's resources and their relations to the functional structure, control structure and organizational (responsibilities) structure. [CIM-OSA].
Response Time
The total time necessary to send a message and receive a response back at the sender exclusive of application processing time.
Material that has been rejected by the buyer's inspection department and is awaiting shipment back to the Supplier for repair or replacement. [APIC].
(1) The process of correcting a defect or deficiency in a product or part. (2) Units of product requiring correction.
RISC (Reduced Instruction Set Computer)
A computer architecture using a small set of instructions at the hardware level. RISC enables a complex processor to be built from very high-speed, simple components.
RM Energy Utilization
Total of raw materials, parts, tools and incoming energy, consumed or transferred on hourly, daily, monthly basis.
RM Order Request
Request to order raw materials, quality, type specifications, special requirements...
Route Sheet
A document that specifies the operations on a part and the sequence of these operations, with alternate operations and routings where feasible. It also can include material requirements (kind and quantity), machining tolerances (tool, jig and fixture requirements) and the time allowances for each operation. [APIC].
A network device that interconnects two computer networks that have the same network architecture. A router requires OSI Level 1, 2 and 3 protocols (see Bridge and Gateway).
A document describing the manufacture of a particular item and specifying the sequence of operations, transportation, storage and inspections to be used. It usually includes the standard times applicable, the machines, equipment, tools, operations, labor requirements and materials that are required for each operation.
RPC (Remote Procedure Call)
A mechanism that extends the concept of a local procedure call, to a fully distributed computing environment.
A messaging standard, also known as MMS, under development in EIA for communication between factory floor devices. It uses ASN.1 for data encoding (see ASN.1 and MMS).
