ASys Roadmap 2.0

Towards robust autonomy (again)

3. 0



Sanz / The ASys Roadmap V3 / 2014 10 21

autonomy – literally:

control of the self from the self

from the Greek autos (self)

and nomos (a law)




Robustness – firm and hard

Resilience – leaping back




IEEE Definition of Robustness

"The degree to which a system or component can function

correctly in the presence of invalid inputs or stressful

environmental conditions."

IEEE Standard Glossary of Software Engineering




Robustness and Resilience

!

Robustness = The degree to which a system can keep

some features in the presence of invalid states.

- States may be partial (e.g. Invalid inputs).

! Resilience = The degree to which a system can recover

some features after their loss.

- Features may be functions, but … not necessarily?

- In essence … “robustness” is “functional robustness”

and “resilience” is “functional resilience” ?




“Keep on doing what you were doing”

!

Because you are so strong that nothing can beat you

- System functions are robust: they never break

!

Because you always get up again

- System functions are resilient: they resurrect

! R&R is always related to a system (S) and a set of

functions (F) or features

4 R Dimensions

!

Robustness:Inherent strength, resistance

!

Redundancy :

System properties that allow for alternative options,choices, substitutions

!

Resourcefulness:Capacity to mobilize needed resources

!

Rapidity :Speed with which disruption can be overcome and servicerestored

ROADMAP

Concrete (or not so much) steps



The Work to Do

!

Provide the tooling necessary for this:

- The conceptual framework

-

The methodology

- The full life-cycle toolchain

- The reusable assets

! To support the “systems understand systems” vision

A Model-based Approach

!

Engineers use system models to support their activity.

! One of the central topics is the pervasive model-based

approach: model-based autonomy

- An ASys will be using models to perform its activity.

- An ASys will be built using models of it.

-

An ASys can exploit its own very models in driving itsbehavior.



Names from the past

!

ICa: Integrated Control Architecture

- The achitectural framework

!

ICe: Integrated Control Environment

- The toolset

! ICm: Integrated Control Methodology

- The methodology

ICb: The Integrated Control Broker

ICa



Some ASys Components

!

ICa : An Integrated Control Architecture. The reference frameworkfor modular construction of complex software-intensive

controllers. Old; never captured formally.

! ICb : A CORBA broker for the Integrated Control Architecture.

The core software infrastructure. Obsolete! DDS

! OASys : An ontology that underlies all ASys efforts. To have in the

mind of the engineer; to have in the mind of the ASys; to be used

in the synthesis of the ASys. Merge with others?.

! SOUL: An Universal Cognitive Architecture with Self-Awareness.

A Metacognitive real-time architecture that realises the model-

based cognition view. Still in the (thin) air.



Some ASys Components

!

ICe: The Integrated Control Environment. A systemdevelopment environment to exploit the ASys technology

in the construction of ASys. Pre-proof of concept.

! ICm : An Integrated Control Methodology. The

specification of an engineering process to build ASys.

Real?

! RCT : A Robot Control Testbed. A case study in robot

control. To consolidate and leverage.

! PCT : A Process Control Testbed. A case study in

process control. To consolidate and leverage.



POSSIBILITIES

Thinking about




Design Architectural Cores

!

The agent builds a functionalmodel of itself that is:

- Fully integrated

-

Continously updated

- Actionable

!

This very self model is at thesame time the cause and the

effect of the agent actions

Plant

Control

Actionable self-model

IDEAS AND PLANS

Anything concrete?




Look for a more sellable profile

!

A new topic?:

! Systems that see systems are able to cognitively integrate

with humans that see systems to provide increased R&R

Mixed initiative self-aware

socio-technical systems




Things to do in a (new) roadmap for ASys

Consolidate

! Have (two) real ASys

!

Document framework,methodology, tools and

assets

! Permeate ontologies

! Model-driven engineering

process

Continue Development

! Tooling

!

Testbeds

! Components

! Evolve framework and

ontology

Leverage




Hot topics (for me)

!

Real-world showable applications !!!

! Core concepts and architectural patterns

!

Reusable cognitive components and architectures

! Full life-cycle engineering method (and associate tooling)

! Model-based real-time operation

! Federation of ASys (esp. with humans)




Immediate Actions

!

Re-issue the Asys Vision (V2) report

! Consolidate (a couple) of simple systems

!

Issue the ASys Framework report

! Specify the ASys Roadmap in more detail (with dates, as a

Redmine project?)

!

Set new server / Activate Asys@redmine
