Initial requirements drift, environments change.
and thus deal with the problems outlined above.
The computer system may needs to be able to:
These generally require the system to have an explicit set of requirements /SLAs (so can evaluate) and the semantics of components of the system
Nowadays the field of SOA emphasises the idea of putting components together to create systems .. EG
(cf PhD student Faisal Mustafa who is looking into this)
See my website http://scom.hud.ac.uk/scomtlm/ for details
Create formalisation of functional requirements (the CPS), automate the solution / code writing – code “self-maintenance”
Use “training data” to test the CPS-generated code, learning processes both find the requirements that are to blame for errors, and invent a requirements fix to satisfy the training data. A new program is automatically derived – auto-bug fixing and “self-learning”
Produce platform to ease the process of automated planning – “self-management”
many systems for data gathering (various types of traffic detectors, cctv)
many ways to influence and control: traffic lights, variable speed limits, variable message signs, local radio, satnav (near future?)
System control involves forming and executing a strategy to control and hence optimise the network
Data services becoming standardised
Road strategies semi-formalised
Some ‘intelligent’ systems exist but on a small scale
