Dealing with the complexity

May 8, 2015


5

Dealing with the complexity: The diversity of companies and toolsets is now enormous and poses many challenges. Previous approaches to tool integration have generally involved:

a) Copying out the relevant information from one domain’s tool into another b) Building a proprietary adapter to bridge the toolsets.

a)  Is not ideal since data is duplicated which puts you at risk when one set of data is changed.

b)  Is not ideal since this locks you in to one tool and also leaves you vulnerable when a vendor releases a new update.

The OSLC approach

Why Airbus believe the OSLC approach looks promising “Open Services for Collaboration” OSLC seeks to take the same standards that made the internet so successful and apply them to Systems Engineering. This means data must be accessible through a URI using HTTP. So long as a tool is OSLC compliant, it is possible to access the resources of that tool without knowing the inner workings. So long as the tool providing the resources has a URL to which information and services can be located and can respond to HTTP commands, then collaboration in possible.

Extending OSLC

Human Factors Engineering

Human Factors is the practice of the proper design of systems so as to take into consideration the needs of the human user. The smartest and most sophisticated system will still fail if the human does something unexpected.

Human Factors Example

Air France Flight 296 June 1988

First flight of a new ‘fly by wire’ - the plane performed the flyover at 30 feet, skimmed the treetops of the forest at the end of the runway, and crashed to the ground—killing three passengers. This was the first

crash of an A320 aircraft.

1) Investigations revealed that over confidence in the flight

protection system were a factor in the cause of the crash.

2)The flight protection system was designed to prevent the pilot from

performing dangerous actions

3)The flight protection system was used in rehearsal many times without

problem

4)During the landing in June, the flight protection system was turned off

and the pilot wasn’t aware.

5)The Pilot was lulled into a false sense of security without realising his performance in the A320 was in fact due to the flight protection system.

Examples of OSLC in Airbus

Human Factors:

Currently, human factors work is often done in a very loose way.

The Problem. Often, research is conducted in the form of surveys and

Questionnaires. Sometimes on paper and often in a textual non formalised way.

Linked Data The linked data approach is interesting as it would allow

results from human factors work to be embedded straight into an Architectural model.

Objectives: •  To address the development and qualification of Adaptive cooperative systems. •  To integrate the HF tools and techniques with a Human Factors Reference Technology Platform to

foster interoperability.

Expected benefits: •  Reinforce Airbus DS skills and competence in integrating Human Factors into the design of border

surveillance systems. •  Optimised Human/Machine interface for more effective border control operatives.
