The work of preparing International Standards is normally carried out through ISO
17、technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organisations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clo
18、sely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft I
19、nternational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of I
20、SO 18629 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18629-14 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC4, Industrial data. A complete list of parts of IS
21、O 18629 is available from the Internet. http:/www.tc184-sc4.org/titles ISO 18629-14 : 2006 (E) ISO 2006 All rights reserved vi Introduction ISO 18629 is an International Standard for the computer-interpretable exchange of information related to manufacturing processes. Taken together, all the parts
22、contained in the ISO 18629 Standard provide a generic language for describing a manufacturing process throughout the entire production process within the same industrial company or across several industrial sectors or companies, independently from any particular representation model. The nature of t
23、his language makes it suitable for sharing process information related to manufacturing during all the stages of a production process. This part of ISO 18629 provides a description of the core elements of the language defined within ISO 18629. All parts of ISO 18629 are independent of any specific p
24、rocess representation or model proposed in a software application in the domain of manufacturing management. Collectively, they provide a structural framework for improving the interoperability of these applications. INTERNATIONAL STANDARD ISO 18629-14 : 2006 (E) ISO 2006 All rights reserved 1 1 Sco
25、pe This part of ISO 18629 provides a representation of the concepts that belong to the outer core of the language, through a set of axioms and definitions. These axioms provide an axiomatization of the semantics for terminology in this part of ISO 18629. The following is within the scope of this par
26、t of ISO 18629: resource; relationships between resources and activities; resource sets; additive quantities. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references

ISO 18629-1 3.1.3 definitional extension extension of PSL-Core that introduces new linguistic items which can be completely defined in terms
32、 of the PSL-Core NOTE: Definitional extensions add no new expressive power to PSL-Core but are used to specify the semantics and terminology in the domain application. ISO 18629-1 3.1.4 extension augmentation of PSL-Core containing additional axioms NOTE 1 The PSL-Core is a relatively simple set of
33、axioms that is adequate for expressing a wide range of basic processes. However, more complex processes require expressive resources that exceed those of the PSL-Core. Rather than clutter the PSL-Core itself with every conceivable concept that might prove useful in describing one process or another,
34、 a variety of separate, modular extensions need to be developed and added to the PSL-Core as necessary. In this way a user can tailor the language precisely to suit his or her expressive needs. NOTE 2 All extensions are core theories or definitional extensions. ISO 18629-1 3.1.5 grammar specificatio

36、non-logical symbols. For ISO 18629, the non logical part of the lexicon consists of expressions (constants, function symbols, and relation symbols) chosen to represent the basic concepts of the ontology.

38、 further completion NOTE Manufacturing processes may be arranged in process layout, product layout, cellular layout or fixed position layout. Manufacturing processes may be planned to support make-to-stock, make-to-order, assemble-to- order, etc., based on strategic use and placements of inventories

ISO 15531-1 3.1.10 primitive concept lexical term that has no conservative definition ISO 18629-1 3.1.11 primitive lexicon set of symbols in the non-logical lexicon which denote primitive concepts NOTE Primitive lexicon is divided into constant, function and relation symbols.

40、ocess structured set of activities involving various enterprise entities, that is designed and organised for a given purpose NOTE The definition provided here is very close to that given in ISO 10303-49. Nevertheless ISO 15531 needs the notion of structured set of activities, without any predefined
41、reference to the time or steps. In addition, from the point of view of flow management, some empty processes may be needed for a synchronisation purpose although they are not actually doing anything (ghost task). ISO 15531-1 3.1.13 resource any device, tool and means at the disposal of the enterpris
42、e to produce goods or services NOTE 1 Adapted from ISO 15531-1, so that resources as defined in ISO 15531-1 except raw material, products and components that are considered from a system theory point of view as parts of the environment of the system and do not belong to the system itself. Furthermor
43、e This definition includes ISO 10303-49 definition but is included in the definition that applies for ISO 18629-14 and ISO 18629-44 that also include raw materials and consumables as well as ISO 18629-13. ISO 18629-14 : 2006 (E) ISO 2006 All rights reserved 4 NOTE 2 Resources as they are defined her
44、e include human resources considered as specific means with a given capability and a given capacity. Those means are considered as being able to be involved in the manufacturing process through assigned tasks. That does not include any modelling of an individual or common behaviour of human resource
45、 excepted in their capability to perform a given task in the manufacturing process (e.g.: transformation of raw material or component, provision of logistic services). That means that human resources are only considered, as the other, from the point of view of their functions, their capabilities and
46、 their status (e.g.: idle, busy). That excludes any modelling or representation of any aspect of individual or common social behaviour. ISO 15531-1 3.1.14 theory set of axioms and definitions that pertain to a given concept or set of concepts NOTE this definition reflects the approach of artificial
47、intelligence in which a theory is the set of assumptions on which the meaning of the related concept is based.

It is composed of a lexicon, an ontology, and a grammar for process descriptions. NOTE 1 PSL is a language for spe

As such, it is different from other languages such as EXPRESS (defined in ISO 10303-11) and used for example in ISO 10303-41, ISO 10303-42, ISO 10303-49, ISO 13584, ISO 15531 and ISO 15926, that are modelling languages.
