CENTRALISED CONTROL CENTRE

[onestrangeday]

Hi PJW:

I've read through the attached document. I am thinking if I am a TCS engineer, in what condition would it better to design a duplicated Control Centre ?
(obviously, it's going to cost much and it probably would not accepted by the customers)

(The main reason I could think about is for having duplicated control centre is for the goals of achieving high reliability for the control centre, especially if the control centre is in a very complex and busy network and loss of occ control could cost a big profit loss....)

and what are the major issues that could resulted from duplicated Control Centres? (increase of complexity of traffic control system architecture, increase in the cost of future maintenance cost)

Over the last weeks the London Study group has considered the part question
A new control centre is to be used for centralised control of a complex line or network. What features should be included in the design of its systems in order to achieve sufficient availability for its purpose in a cost effective manner?

The attached isn't a model answer; apart from anything else it is longer than could realistically be achieved and would need to be less explanatory and more tersely focussed on the essentials to answer the question, but it should be a good source of the sort of material from which such an answer can be constructed.
