The work of preparing International Stand
15、ards is normally carried out through ISO 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 ta
16、ke part in the work. ISO collaborates closely 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. Draft International Standards (DIS) adopted
17、 by 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 ISO 18629 may be the subject of pat

ISO 18629-11 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Sub-committee SC4, Industrial data.

Taken together, all the parts contained in the ISO 18629 Standard
20、 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 this language makes it suitable for
21、sharing process information related to manufacturing during all the stages of a production process. This part provides a description of the core elements of the language defined within the International Standard. This part of ISO 18629 and all other parts in ISO 18629 are independent of any specific
22、 process 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. ISO 2005 All rights reserved viINTERNATIONAL STANDARD ISO 18629-11 : 2005 (E) Ind

27、2005 (E) 3 Terms, definitions, and abbreviations 3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1.1 axiom well-formed formula in a formal language that provides constraints on the interpretation of symbols in the lexicon of a language ISO 18
28、629-1 3.1.2 conservative definition definition that specifies necessary and sufficient conditions that a term shall satisfy and that does not allow new inferences to be drawn from the theory ISO 18629-1 3.1.3 core theory set of predicates, function symbols and individual constants, associated with s
29、ome axioms, the primitive concepts of the ontology 3.1.4 data a representation of information in a formal manner suitable for communication, interpretation, or processing by human beings or computers ISO 10303-1 3.1.5 defined lexicon set of symbols in the non-logical lexicon which denote defined con
30、cepts NOTE Defined lexicon is divided into constant, function and relation symbols. EXAMPLE terms with conservative definitions. ISO 18629-1 3.1.6 extension augmentation of PSL-Core containing additional axioms NOTE 1 The PSL-Core is a relatively simple set of axioms that is adequate for expressing
31、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 ISO 2005 All rights reserved 2 ISO 18629-11 : 2005 (E) pro
32、cess or another, 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 3.1.7 gram
33、mar specification of how logical symbols and lexical terms can be combined to make well-formed formulae ISO 18629-1 3.1.8 individual element of an interpretation domain, in logic, considered as not divisible without loss of identity EXAMPLE an individual constant is a symbol that is used to refer to
34、 some fixed individual object : it is the equivalent in logic of the “name“ in the everyday language. In first-order logic, arguments of predicates are always individual constants. NOTE 1 for further information, see 5. NOTE 2 this term is commonly used in formal logic. NOTE 3 in first order logic,
35、the only individuals are individual constants. 3.1.9 information facts, concepts, or instructions ISO 10303-1 3.1.10 interpretation universe of discourse and assignment of truth values (TRUE or FALSE) to all sentences in a theory NOTE See annex C for an example of an interpretation. 3.1.11 language
36、combination of a lexicon and a grammar ISO 18629-1 ISO 2005 All rights reserved 3ISO 18629-11 : 2005 (E) 3.1.12 lexicon set of symbols and terms NOTE The lexicon consists of logical symbols (such as Boolean connectives and quantifiers) and non-logical symbols. For ISO 18629, the non logical part of
37、the lexicon consists of expressions (constants, function symbols, and relation symbols) chosen to represent the basic concepts of the ontology. ISO 18629-1 3.1.13 linear ordering set of elements with a binary relation between any two elements that is transitive, irreflexive and antisymmetric EXAMPLE

39、ial to convert it from the raw material or a semifinished state to a state of 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,
40、assemble-to-order, etc., based on strategic use and placements of inventories. ISO 15531-1 ISO 2005 All rights reserved 4 ISO 18629-11 : 2005 (E) 3.1.16 model combination of a set of elements and a truth assignment that satisfies all well-formed formulae in a theory NOTE 1 The word “model“ is used,
41、in logic, in a way that differs from the way it is used in most scientific and everyday contexts: if a sentence is true in a certain interpretation, it is possible to say that the interpretation is a model of the sentence. The kind of semantics presented here is often called model-theoretical semant
42、ics. NOTE 2 A model is typically represented as a set with some additional structure (partial ordering, lattice, or vector space). The model then defines meanings for the terminology and a notion of truth for sentences of the language in terms of this model. Given a model, the underlying set of axio
43、ms of the mathematical structures used in the set of axioms then becomes available as a basis for reasoning about the concepts intended by the terms of the language and their logical relationships, so that the set of models constitutes the formal semantics of the ontology. ISO 18629-1 3.1.17 ontolog
44、y a lexicon of specialised terminology along with some specification of the meaning of terms in the lexicon NOTE 1: structured set of related terms given with a specification of the meaning of the terms in a formal language. The specification of meaning explains why and how the terms are related and
45、 conditions how the set is partitioned and structured. NOTE 2: The primary component of a process specification language such as ISO 18629 is an ontology The primitive concepts is the ontology according to ISO 18629 are adequate for describing basic manufacturing, engineering, and business processes
46、. NOTE 3: The focus of an ontology is not only on terms, but also on their meaning. An arbitrary set of terms is included in the ontology, but these terms can only be shared if there is an agreement about their meaning. It is the intended semantics of the terms that is being shared, not simply the t
47、erms. NOTE 4: Any term used without an explicit definition is a possible source of ambiguity and confusion. The challenge for an ontology is that a framework is needed for making explicit the meaning of the terms within it. For the ISO 18629 ontology, it is necessary to provide a rigorous mathematic
48、al characterisation of process information as well as a precise expression of the basic logical properties of that information in the ISO 18629 language.
