Service Modelling Language and Potentials for a New Standard

Workshop IWEI 2013 – Enschede, NetherlandsMarch 26, 2013

Introduction

• Research work carried out under the frame of FP7 MSEE Integrated Project

• MSEE: Transition from product based manufacturing company to product-related service virtual enterprise

• Service (system) modelling to support service engineering and implementation

• Approach: use of Enterprise Modelling techniques and Model Driven

Service Model Driven Engineering Architecture

Human related

Business Service Modelling

Technology Independent Modelling

Technology Dependent Modelling

Services in virtual enterprises(software, process, human, material

handling devices (machine, robots), etc…)

Implementation(software coding, select human and machine components from the market)

Template ‘Process’

Header Construct label [‘Process’] Identifier [Identifier of the process instance] Name [name of the process instance] Body Objective [Short description of the process objectives] Trigger [Condition this process instance is triggered] Result [Output of this process instance] Constraint [Constraint that may apply on this process instance] Sub-process [List of sub-process] [Graphical representation]

Example: IDEF3 Process diagram Relationships to other model elements SERVICE [Identifier/name of service concerned by the process: described by Service template]

RESOURCE [Identifier/name of resource used by the process: described by Resource template] Other Relationships RELATED TO MODEL LEVEL [Refer to BOM, TIM, TSM modelling level] : BOM REALTED TO SLM PHASE [Refer to service lifecycle phases] : Requirement

ServiceElectrical car battery maintenance

ProcessPR1=On line service booking and payment process

Customer

Electric car buyers

Product

Electric Car Battery

Value-Improve 'image of car manufacturer -Increase confidence of customer to buy electrical car

Decision structure

To be defined

DecisionD1=Scheduling decision; D2=Supplying decision; D3=Resource allocation decision

Performance IndicatorPI1=Service rate (number of services provided on time/total number of services requested)

FunctionalityF1=cleaning; F2=Recharging; F3=Reparing

Resource

R1=Technician; R2=Charger

OrganizationDecentralized networked organization

Partners-Feu Vert-Speedy-Others

Stakeholder-Car manufacturer-Battery providers-Project sponsor (bank)

person/organisation with authority to design/maintain this particular instance]

Body DOMAIN [Domain of the service] Maintenance (after sale)DESCRIPTION [short textual description of the functionality /

utility]This service is to cleaning, recharging, repairing (replacing parts) of electric car battery

OBJECTIVE [Short textual description] keep battery function at its 90% capacity during 3 months after a maintenance

CONSTRAINT [Short textual description] Need 24 hours delay to deliver service, must booking the service from Web

Potentials for Standardisation

Adopt MDSEA as a standard service modelling architecture under which modelling language can be developed

Develop metamodel of service modelling constructs at the three modelling levels under MDSEA, focus on BSM level?

Map service modelling constructs to existing relevant enterprise modelling techniques

Relevant standardization working groups in enterprise modelling standardisation (CEN TC310/WG1 and ISO TC184 SC5/WG1).
