20、O member bodies). The work of preparing International Standards 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 organizations, gove

21、rnmental and non-governmental, in liaison with ISO, also take 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 the ISO/IEC

22、Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International 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

23、 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 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18629-13 was prepared by Technical Committee ISO/TC 184, Industr

25、r-interpretable exchange of information related to manufacturing processes. Taken together, all the parts 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 severa

26、l industrial sectors or companies, independently from any particular representation model. The nature of this 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 e

27、lements of the language defined within ISO 18629. All parts of ISO 18629 are independent of any specific 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

28、of these applications. INTERNATIONAL STANDARD ISO 18629-13: 2006 (E) ISO 2006 All rights reserved 11 Scope This part of ISO 18629 provides a representation of the primitive concepts related to ordering and durations constraints for activities. The following is within the scope of this part of ISO 18

29、629: subactivity occurrence orderings; duration; iterated occurrence orderings; occurrence tree endomorphisms; activity envelopes. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、ned concepts NOTE Defined lexicon is divided into constant, function and relation symbols. EXAMPLE terms with conservative definitions.

37、some model 3.1.8 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 a wide range of basic processes. However, more complex processes require expressive resources that exceed those of the PSL-Core. R

38、ather than clutter the PSL-Core itself with every conceivable concept that might prove useful in describing one process 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

39、or her expressive needs. NOTE 2 All extensions are core theories or definitional extensions. ISO 18629-1 3.1.9 grammar specification of how logical symbols and lexical terms can be combined to make well-formed formulae ISO 18629-1 3.1.10 homomorphism mapping between sets that preserves some relation

40、 on the elements of the set 3.1.11 interpretation universe of discourse and assignment of truth values (TRUE or FALSE) to all sentences in a theory NOTE See annex B for an example of an interpretation. ISO 18629-11 3.1.12 language combination of a lexicon and a grammar ISO 18629-1 3.1.13 lexicon set

41、 of symbols and terms ISO 18629-13 : 2006 (E) ISO 2006 All rights reserved 4 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 the lexicon consists of expressions (constants, function symbols, an

42、d relation symbols) chosen to represent the basic concepts of the ontology. ISO 18629-1 3.1.14 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, in logic, in a way that differs from the way it is used in

43、 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 semantics. NOTE 2 A model is typically represented as a set with

44、 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 axioms of the mathematical structures used in the set of axiom

45、s 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 3.1.15 monomorphism one to one mapping that preserves some relation on t

46、he elements of the set 3.1.16 ontology 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 wh

47、y and how the terms are related and 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 in the ontology according to ISO 18629 are adequate for describing basic manufacturing,

48、 engineering, and business processes. 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 th

49、at is being shared, not simply the terms. 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 mathematical characterisation of process information as well as a precise expression of the basic logical properties of that information in the ISO 18
