ISO/TC 184/SC 4/WG 15 - Digital manufacturing

This document provides an overview and general principles of a digital twin framework for manufacturing including: — terms and definitions; — requirements of the digital twin framework for manufacturing.

This document identifies technical requirements for information exchange between entities within the reference architecture. The requirements for information exchange in the following networks are within the scope of this document: — user network that connects the user entity and the digital twin entity; — service network that connects sub-entities within the digital twin entity; — access network that connects the device communication entity to the digital twin entity and to the user entity; — proximity network that connects the device communication entity to the observable manufacturing elements.

This document provides a reference architecture for the digital twin in manufacturing including; — reference model from domain and entity point of view; — functional view specifying functional entities supported by the entity-based reference model.

This document provides a list of basic information attributes for the OMEs: — examples of information attributes are given; — standards that can define these information attributes are discussed in Annex A.

This document describes the general content and structure of the entire QIF information model. It describes the highest level data structures of QIF, that are expanded in Clauses 6 through 12 using data dictionaries and XML schema files. All QIF XML schema files can be found at www.qifstandards.org. This document also describes practices for forming QIF instance files, called "documents," that support quality workflow scenarios. Its focus is to show how the QIF information model, and data formed into XML instance files, support the entire scope of model based definition manufacturing quality workflow. It describes how the information model is partitioned among the XML schema files and contains all terms used in the subject area clauses. The purpose of this document is to orient potential users of QIF to the organization of the information model to make their study of the details more rewarding and efficient. It should also help solution providers and users to evaluate QIF for their uses, without needing to go to the lowest technical details of the XML schemas. The information model narrative focuses on the approach to modeling the core data structures of QIF, which model the content of ASME GD&T and ISO GPS, and the plans and results data elements defined in Dimensional Measuring Interface Standards (DMSI) ISO 22093 and ANSI/DMSC DMIS 5.3. The material on XML practices describes consistent design practices to be used by QIF working groups who will be designing new schemas. It should also help data processing experts to write software that writes and reads manufacturing quality data using the XML schemas.

The following aspects are within the scope of ISO 18828-3:2017: · general overview of the main information flows within the reference planning process; · basic pattern to describe the main information flows; · detailed description of every main information flow; · state notation structure of the main information flows objects; · detailed descriptions for each information object state; · proposal of checklists for benchmarking information objects. The following items are outside the scope of ISO 18828-3:2017: · information flows to intersecting areas, including high-level planning; · data models for production planning; · complete description of all possible information flows/objects within production planning; · workflow engines for automated production planning; · production facilities planning/manufacturing facilities planning (physical plant and equipment); including any kind of resource that is not directly related to the manufacturing process; · value chain (inbound logistics, operations management, outbound logistics, marketing and sales); · process simulation/safeguarding; · investment planning during production process management.

ISO 18828-2:2016 describes a reference planning process for seamless production planning. The scope of the discussed reference process focusses on the planning of production systems such as make-to-stock or assemble-to-order production. The analysis of the process activities has been limited to those within the production planning. The following aspects are within the scope of ISO 18828-2:2016: · general overview of the reference planning process; · basic principles of the process model; · description of each level identified within the reference planning process for production planning; · structure of activities and relations within each planning discipline; · dependencies of interdisciplinary activities. The following items are outside the scope of ISO 18828-2:2016: · material requirement planning/manufacturing resource planning; · production order control; · production process; · early stage product design; · order management, inventory management, purchasing, transportation, warehousing; · production facilities planning/manufacturing facilities planning (physical plant and equipment), including any kind of resource that is not directly related to the manufacturing process; · value chain (inbound logistics, operations management, outbound logistics, marketing and sales); · resource visualization; · process simulation.

ISO 18629-42:2006 provides definitions written in the language of ISO 18629 for concepts related to activity extensions in the process specification language. The process specification language is aimed at structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.

ISO 18629-43:2006 provides definitions written in the language of ISO 18629 for concepts related to activity extensions in the process specification language. The process specification language is aimed at structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.

ISO 18629-41:2006 provides definitions written in the language of ISO 18629 for concepts related to activity extensions in the process specification language. The process specification language is aimed at structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.

ISO 18629-44:2006 provides definitions written in the language of ISO 18629 for concepts related to activity extensions in the process specification language. The process specification language is aimed at structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.

ISO 18629-14:2006 provides a description of the resource theories of ISO 18629, which defines elements needed for defining resources, resource roles, and resource sets.

ISO 18629-13:2006 provides a description of the duration and ordering core theories in ISO 18629, which defines elements needed by most of the extensions of the process specification language (PSL) aimed at structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.

ISO 18629-12:2005 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 the ISO 18629 Outer core. The following are within the scope of ISO 18629-12:2005: the aggregation of activities and sub-activities; discrete activities and state; constraints on the occurrence of activities; concurrency for primitive activities; complex activities; occurrences of complex activities.

ISO 18629-11:2005 provides a representation of the concepts of PSL Core using a set of axioms written in the basic language of ISO 18629. The representation of the concepts common to all processes is within the scope of ISO 18629-11:2005.

ISO 18629-1:2004 provides a general overview of the different series of parts of ISO 18629, which defines a process specification language aimed at identifying, formally defining and structuring the semantic concepts intrinsic to the capture and exchange of process information related to discrete manufacturing.
