Motivation

Integrate business level with factory floor

•How to get a model in a systemized way?

•What standards/tools map to that model?

•Towards integration

CIM Computer Integrated Manufacturing• Computer automated system to organize

and link high level and low level information/functions:– design, analysis, planning, purchasing, cost

accounting, inventory control, and distribution– Material handling, actuators control and

monitoring

Enterprise Modelling

• Abstract representation of resources in an enterprise.– Description– Definition– Relations– Structure– Processes

• Models needed for:– Decision taking, integration

GERAM—Generalised Enterprise Reference Architecture and Methodology

• Tool used for enterprise modelling

• Developed in 1990s by  IFAC/IFIP Task Force on Architectures for Enterprise Integration

• Collects frameworks for enterprise integration and provides a generic version

GERAM framework components

PERA, Purdue Enterprise Reference Architecture

• PERA is a GERAM, a Generalized Enterprise Reference Architectural Model.

• Represents an enterprise system as a model• Designed for Process, Manufacturing and

Services Industries• Goes through the full life cycle of the system.• Facilitates decisions in planning, integration• Proposed to be an international standard

PERA components

• Main components in an enterprise:– Physical plant (facilities)– People– Control and information

systems

ISA-95

• Interfaces between business and factory floor

• Boost integration between ERP and MES

• For all industries: batch, continuous, discrete

• Consistent terminology

• Defines levels, functions, information flow, data models.

ISA-95 levels

09.04.23 14

ISA-95: Exchanged information and data models• Defines information exchanged

between level 4 and level 3

• Provides data models

• UML class diagrams notation

B2MLL Business To Manufacturing Markup Language

• Implementation of ISA-95

• XML Schema Definition (xsd)

Approach

Implementation: PERA model

09.04.23 18

Implementation: ISA-95 UML model

09.04.23 19

Implementation: ISA-95 conversion tool

09.04.23 20

Implementation:B2MML compliant XML

Conclusions

• Enterprise-manufacturing systems integration requires a methodology to maintain overall life cycle of production system

PERA can be a possible solution

• Tools and standardized data interchange formats are required to support the use of the methodology

ISA-95 & B2MML are suitable implementations
