ISO 15531-43:2006

Overview

ISO 15531-43:2006 - part of the ISO 15531 series on industrial manufacturing management data - defines a data model for manufacturing flow management, focused on representing the information needed for monitoring and exchanging material and information flows in production. The standard develops a conceptual flow model (expressed in the EXPRESS language) to support planning, scheduling, controlling and monitoring of manufacturing flows inside the plant and between production processes.

Key points:

• Focuses on flow control and flow management data (materials and information).
• Uses EXPRESS (ISO 10303-11) for data modelling and integrates constructs from related standards.
• Deliberately excludes detailed modelling of external exchanges, resource usage, and time representation (those are covered in other parts of ISO 15531).

Key topics and requirements

• Conceptual flow model: definitions for processes, flows, and relationships between manufacturing processes (including carrying, junction, and division processes).
• Data entities and types: explicit entities such as process, flow, material_flow, information_flow, raw_material, component, and property/value constructs (e.g., process_property_value, flow_property_value).
• Schema and subtype constraints: standardized schema definitions and subtype constraints to ensure consistent representation and exchange.
• Use of EXPRESS and ASN.1: model expressed in EXPRESS; Annex material covers ASN.1 identifiers and EXPRESS-G diagrams to support implementation and interoperability.
• Normative references: aligns with other ISO TC184/SC4 resources (e.g., ISO 10303, ISO 13584) and leverages integrated generic resources for process structures and properties.

Applications and who uses it

ISO 15531-43 is intended for organizations and professionals who need to standardize and exchange manufacturing flow data:

• Manufacturing systems integrators and MES/ERP implementers enabling consistent flow monitoring and control data exchange.
• Plant operations and production planners coordinating material/information flows across cells, machines and suppliers.
• Software vendors developing interoperability layers, data exchange formats, or digital manufacturing platforms.
• Standards bodies and technical architects aligning data models across product, parts library and process standards.

Practical applications include flow monitoring, interoperability between production cells and suppliers, electronic representation of production flows for scheduling and control, and integration of manufacturing flow data with product and process information systems.
