AS9100
AS9100 is a Quality Management System for the aerospace
industry issued by the G-14 Americas Aerospace Quality Group (Aaqg). As a follow
up on AS9000, AS9100 follows the same setup as ISO 9001. Beside the ISO 9001 requirements,
AS9100 adds about 100 additional requirements. You can get a PDF of the standard
for about USD 60.
Batch
A Batch can be used for grouping parts or for parts that are
non-discrete. Batches can have a Unique ID. The individual parts within
a batch will all have the same Unique Batch ID. Within EZ-MES batches are non-discrete
parts that can have any number for their quantity.
Example of Batches: A bag of 500 Screws. Individual screws will not get a serial
number, but the bag can get a serial number (batch number). This will enable full
traceability, the system will keep track where all screws will end up.
Another example is a bottle of glue. The bottle of glue will be seen as an non-discrete
part with a quantity of 1. Consumption of the bottle of glue can happen in fractions,
e.g. 0.05 of the unit of the full bottle.
Bill of Material (BOM)
A.k.a: Parts List
The Bill of Material is a list of all materials (parts and consumables) needed to
create a product. Within EZ-MES the Bill of Material is defined on the
Part Definition. Besides the definition on the Part Definition the BOM is
implicitly defined on the Flow Definition by the Materials the Flow is consuming.
Bill of Process (BOP)
A.k.a: Flow Defintion; Work Plan
The Bill of Process can be seen as an extended Bill of Material, beside having the
infomation of the materials that are needed to create a product, it also covers
the information on how the product is created. This includes the sequence of operations,
the used equipment, required labor skill etc.
This functionality in EZ-MES is covered by the
Flow Definition
CFR
The Code of Federal Regulations (CFR) is the codification of the general and permanent
rules and regualtions published in the Federal Register by the executive departments
and agencies of the Federal Government of the United States. Read more...
Title 21 Chapter I of the Code of Ferderal Regulations is the portion of the CFR
that governs food and drugs within the United States for the Food and Drug Administration
(FDA)
Title 21 CFR Part 11 of the Code fo Federal regulations deals with the FDA guidelines
on electronic records and electronic signatures in the United States. Part 11, as
it is commonly called, defines the criteria under which electronic records and electronic
signatures are considered to be trusworthy, reliable and equivalent to paper records.

CIM
CIM stands for Computer Integrated Manufacturing. Outdated model from the 1980s to descibe manufacturing information technology. CIM discribes a manufacturing software model. The CIM pyramid focused on the hierarchy of the manufacturing enterprice. The CIM Pyramid is more or less reused in the ISA 95 model.
CSV
CSV stands for Comma Separated Values format, a.k.a. Comma Separated File. Values
are separated by commas, and rows (records) are separated by line breaks (CLRF).
Fields containing Line Breaks, commas, double quotes should be enclosed in double
quotes. Double quotes in the value are escaped by preceeding them with an other
double quote.

Discrete
A Discrete Part Record only represent a single real-world part or
product, while A Non-Discrete Part Record can represent a Batch of parts
or products, or a fraction of a part or product.
DHR
The Device History Record shows the sequence of operations that were performed on
a product. This information can be obtained on the 'History' tab of the Part Record or when the Part
Record Report is printed.
EZ-MES Object
All information in EZ-MES is stored using EZ-MES Objects. Examples are: Travelers,
Part Records, Flow Definitions etc.
Flow Definition
The
Flow Definition defines the sequences of steps that represent the production
process.
Within the different industries different nomenclature is used. Different names
for Flow Definition could be:
- Traveler (we use Traveler for an instance of a Flow Definition)
- Routing
- Workflow
- Work Plan
- Recipe
Within EZ-MES we use 'Traveler' to show an instance of a Flow Definition. Other
posibilities are:
- Work Plan - Production Order (Order)
- Traveler - Flow
- Routing - Router
Object State
Most EZ-MES Objects move through different states, the states are dependent per
object. Look in the Objects Manual for a complete
list of the EZ-MES Objects.
Operation
A.k.a.: Step Definition; Step
Products are created by sequencing operations. An operation can have an input which
is transformed into an output using resources. The resources can be a combination
of consumed material, equipment, labor and time. Within EZ-MES the operations are
configured by the Step Definition.
Parts and Part Records
Within the
EZ-MES Manuals if the word 'part' is used, it means the actual real-world
parts or products that you would like to track by using
an
MES system like EZ-MES.
Part Records are the representation of these parts within
EZ-MES. Part Records can be Discrete
or Non-Discrete.
A Discrete Part Record only represent a single real-world part or
product, while A Non-Discrete Part Record can represent a Batch of parts
or products, or a fraction of a part or product.
Part States
Part States are the state of parts that is determined by the Traveler to which the Part Records
are connected. The traveler gets the Part State from the connected Flow Definition
Process State
State of Travelers or Part Records, that depends on the progress of the operation.
Routing
Routing in EZ-MES is defined by Flow Definitions. Flow Definitions serve as the
templates for Travelers. Travelers will perform the actual routing of the parts
throught the production flows.
S88.01
S88, shorthand for ANSI/ISA-88, is a standard addressing batch process control.
It is a design philosophy for describing equipment, and procedures. It is not a
standard for software, it is equally applicable to manual processes.
S88 defines hierarchical recipe management and process segmentation frameworks,
which separate products from the processes that make them. The standard enables
reuse and flexibility of equipment, and provides a structure for coordinating and
integrating recipe-related information across the traditional ERP, MES, and control
domains.
SECS/GEM
(SEMI Equipment Communications Standard/Generic
Equipment Model) Communications protocols between a host computer
and semiconductor manufacturing equipment. SECS is a layer 6 protocol that describes
the content of the messages while GEM is a higher layer application protocol that
defines the messages themselves. SECS/GEM is used to control wafer steppers, lithographic
equipment, etchers, ion implanters and other machines. Ref. PC Magazine
GEM is formally known as SEMI standard E30
SEMI
SEMI is the global industry association serving the manufacturing supply
chains for the microelectronic, display and photovoltaic industries.
Traveler
Unique ID
A unique identifier for a Part, Batch or Lot. Unique Identifiers can only exist
once in the system. Even if the Part Definition is different 2 parts can not share
the same Unique ID. Examples of Unique ID's are Serial Numbers or Batch Numbers
Work in Process (WIP)
A Part Record
(or Part) in various phases of production in a manufacturing plant. This includes
raw material awaiting processing up to final assemblies ready to be received into
inventory. At the moment when parts are added to
inventory, they will not show up on the WIP Report.
