Abstract

y This paper attempts to fuse business with IT in the dynamically changing

and risk adverse environment.

y The authors have successfully discussed the Issues of business and IT

alignment in a well-defined system, namely the shop-floor domain in

discrete production industry through the realization of SOA.

y The paper results in an ANSI/ISA 95 compliant model-driven methodology

for manufacturing operations management.

Intelligent Manufacturing Information Systems

y The objective of vertical integration from high-level Enterprise Resource

Planning (ERP) to the machine level is still unrivalled.

y The existing solution lacked the flexibility and scalability which were not

sufficient for the requirements of todays dynamic production environments.

y With the advent of internet , leveraging the latest technologies to achieve

distributed information systems has become easier.

This figure depicts the internal and external service providers at the

shop floor control level.


5/24

Public Services: It includes machine vendors who offers services like online

maintenance, education support, planning and optimization of production and logistics

systems or other e-Industrial/tele-services.

Private Services: These are company specific and require higher coordination demands

and security.

ERPMM: This ERP handles Purchasing and Inventory.

ERP_PP: This ERP handles Production Planning

SFDC: salesforce.com is a vendor of Customer Relationship Management (CRM).

SCADA: supervisory control and data acquisition refers to a computer system

monitoring and controlling a process.

ATP: Availability to promise checks the of quantities of stock available.

Manufacturing DomainInformationArchitecture

Proposals

y Enterprise Architecture (EA) research led to evolution of many architectures

like MDA (Model Driven Architecture) or GRAI Integrated Method. These

concepts introduced important ideas at regarding modeling, modularization

and abstraction levels, but lacked standardization.

y T

his project, a proposal derived from PERA (an Europian innovationnetwork) utilizes UML and focus on the higher abstraction levels making it

a very promising approach.

y More emphasis on Service Oriented Analysis and Design ( SOAD) is given

in this project. It consists of three phases, namely identification,

specification and realization. This project uses the hybrid SOAD modeling

approach which suggests a combination of Object Oriented Analysis andDesign, BPM and EA techniques.

y Finally author has introduced this concept of a Model driven security

accreditation (MDSA), a combined top-down/bottom-up methodology, for

the shop floors in a user friendly way. It optimizes the trade-off between

flexible interconnectivity and network infrastructure complexity.

Model Driven Service Architecture for the Shop Floor

y Service Oriented Analysis and Design (SOAD) has to bring

together the domain dimensions of Business, Architecture andApplication to a common modelling concept.

Model Driven Service Architecture for the shopfloor



10/24

y Initial modelling of a given shop floor system has to

be supported by focusing on functionality and

connectivity of the system as a whole.



11/24

Shop Floor Tool-Box (SFTB).

y The SFTB is an ANSI/ISA 95 compliant tool box which

enables fast and standardized modelling of particular shop floor

scenarios

y The tool consists of an abstract service repository of basic and

complex services (what dimension), concrete service providers

(who dimension), binding mechanisms and data entities (with

dimension).



12/24

Particular Shop Floor Model (PSFM)

y PSFM can be platform independent or platform specific

y PSFM considers the actual system specification only roughly

y The PSFM has to support long term platform, infrastructure

and service provider decisions through as-is and to-be

comparisons.



13/24

Executable Shop Floor Model(ESFM)

y This is platform specific

yPSFM model has to interact with the ESFM concerning processdefinition.

y The ESFM serves at a tactical level for the (re)design of

service flow definitions which are semantically rich enough forexecutable code generation.

Conclusion1

The project concluded that SOA can be used successfully in shop floor

designs supported by intelligent manufacturing information systems.

SOA is flexible enough to realize decentralized control structures and to

integrate a broad range of service providers in a loosely coupled way. With the proposed MDSA methodology, business and IT alignment has been

possible.

Firstly due to elimination of the following gaps

Implementation layer, which can be a very heterogeneous one in discrete

manufacturing involving sophisticated web applications as well as manualprocessing tasks.

The second gap is the one to the business layer, where business analysts

define processes including goal and performance indicator setting.

Conclusion2

1. The outcome of this project is an ANSI/ISA 95 compliant model driven

methodology for manufacturing operations management.

2. The methodology is flexible enough to embed given shop floor scenariosand components smoothly into the framework with the help of predefined

modeling constructs.
