Problem Statement 2

RQ:how do component-based principles and

practices are used and support the activity of

architecting CPSs?

P

Problem Statement 3

Q: How the Component-Based community can contribute to

engineering CPSs?

Q: How our theories and methods can be adapted to fruitfully

Architecting CPSs?

Q: are these methods encapsulated in new technologies and integrated with the existing component models?

Q: What are the new design challenges in architecting CPS by

Component-Based Principles and Practices?

This Study

Means: a Systematic Literature Reviews(SLR)

4

Investigates how component-based principles and practices are

used and support the activity of architecting CPS

We aim to analyze, classify, and understand existing research

on Component-Based Principles and Practices for Architecting

Cyber-Physical Systems according to our extended framework

Classification Framework for Component Models .

our study,

RQ, Goal

• Studies search • Studies selection • Data extraction

• Data synthesis

• reasoning on the

obtained findings

• evaluating the

quality of our study

STUDY DESIGN - Studies Search and Selection

6

1. The architecting CPS emerged from Embedded Systems

(ES).

2. EFPs not yet fully explored by the community.

3. The extensive use of programming languages suitable for

ES

4. An absence of adaptation and dynamic deployment

7

The selected studies are analyzed,

and data are extracted according to

The construction

(i) the interface

(ii) Binding

(iii)communication

.

The lifecycle

dimension

the support

provided, in certain

points of a lifecycle

of components.

EFPs dimension

define compositions

Modelling. The component model rovide support for the modelling and the design of component-based systems and components. Implementation. The component model provides support for generating and maintaining code.

Storage & Packaging Since components can be developed separately from systems, there is a need for their storage and packaging either for the repository or for a distribution

Deployment. At a certain point of time, a component is integrated into a system.

10

11

Models are almost always used when

specifying CPS component models: 23 different

modelling languages have been found, with

limited use of the UML.

12

Interface operation-based/port-based provides/requires The interface level (syntactic, semantic, behaviour) distinctive features

Binding Hierarchical Endogenous, Exogenous

Interaction Architectural Style Communication type (synchronous/asynchronous)

13

14

15

Identifies support to manage, to specify, and even

define compositions of certain EFPs.

16

Only one third of the studies support EFPs,

mostly timing properties.

General-purpose: component model is not tied to any

domain

Specialized: Component model is specifically tailored to a

given domain

17

General-purpose approaches are far the

most frequent(33 studies ), whereas specialized are

emerging (16 studies)

In specialized :10 out of 16

studies have been published

between

2014 and 2015

Timeline

19

• More than the half of whole primary studies has been

published between 2014 and 2015

• Research on CBSE for CPS is gaining increasing interest

Our study covers the studies published before June 2015

Enlarge the scope to architecting

cyber-physical Systems

Cover the gap between the needs

present in CPS, and what realized

so far.
