24、O) is a worldwide federation of national standards bodies (ISO 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 rep
25、resented on that committee. International organisations, governmental 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 a
26、re drafted in accordance with the rules given in ISO/IEC Directives, Part 2. Draft International Standards (DIS) adopted 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 v
27、ote. 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 18629-12 was prepared by Technical Committee ISO/TC 184, Industrial automation syst

29、uter-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 sev
30、eral 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 provides a description of the core elements of
31、 the language defined within the International Standard. This part of ISO 18629 and all other parts in 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 frame
32、work for improving the interoperability of these applications. ISO 2005 All rights reserved viiiINTERNATIONAL STANDARD ISO 18629-12 : 2005 (E) Industrial automation systems and integration Process specification language Part 12: PSL Outer core 1 Scope This part of ISO 18629 provides a representation
33、 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 the ISO 18629 Outer core. The following are within the scope of this part of ISO 18629: the aggregation of activities an
34、d sub-activities; discrete activities and state; constraints on the occurrence of activities; concurrency for primitive activities; complex activities; occurrences of complex activities. 2 Normative references The following referenced documents are indispensable for the application of this document.

38、r 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 18629-1 3.1.2 conservative definition definition that specifies necessary and s
39、ufficient 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 some axioms, the primitive concepts of the ontology ISO 18629-1 3.1.4 data a r
40、epresentation 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 concepts NOTE Defined lexicon is divided into constant, function and
41、 relation symbols. EXAMPLE terms with conservative definitions. ISO 18629-1 3.1.6 definitional extension extension of PSL-Core that introduces new linguistic items which can be completely defined in terms of the PSL-Core ISO 2005 All rights reserved 2 ISO 18629-1 3.1.7 extension augmentation of PSL-
42、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. Rather than clutter the PSL-Core itself with eve
43、ry 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 or her expressive needs. NOTE 2 All extensions
44、are core theories or definitional extensions. ISO 18629-1 3.1.8 grammar specification of how logical symbols and lexical terms can be combined to make well-formed formulae ISO 18629-1 3.1.9 idempotent element (a) of a set under an internal binary operation (OP) with respect to which : a OP a = a NOT
45、E a function is idempotent when every element of the definition domain is idempotent with respect to it EXAMPLE set-theoretic intersection and union are idempotent, since S S = S and S S = S. 3.1.10 information facts, concepts, or instructions ISO 10303-1 3.1.11 interpretation universe of discourse
46、and assignment of truth values (TRUE or FALSE) to all sentences in a theory NOTE See annex C for an example of an interpretation. 3.1.12 language combination of a lexicon and a grammar ISO 18629-1 ISO 2005 All rights reserved 3ISO 18629-12 : 2005 (E) NOTE: Definitional extensions add no new expressi
47、ve power to PSL-Core but are used to specify the semantics and terminology in the domain application. ISO 18629-12 : 2005 (E) 3.1.13 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
48、 non logical part of the lexicon consists of expressions (constants, function symbols, and relation symbols) chosen to represent the basic concepts of the ontology.
