I have no problem with the notion that the computer can be a tool (because I happen to be a professional computer programmer), and I have no problem with the idea that some useful information might be gleaned by analysing historical data for your area. It seems natural to me that there could be established patterns in terms of the level of load in a particular area at a particular time of the day / week. Fair enough... However, anyone who reckons that they can predict, with the aid of a mother (as opposed to ouigi) board, where the next call is coming from is a bloody fool. Hear ye not of chaos theory? This sort of analysis is the sort of thing you might use when asking yourself somewhat broader questions like "roughly what level of operation cover do I need in this particular station here on Monday mornings...". It is, I would suspect, of precious little use guessing a sequence of events - this happens here, and then that happens there... Aside from that though, the basic fact is that this AAC does not appear to be justified. Why piss off your crews to this extend for something so vague? Why risk health problems like posture, muscle problems etc by pointless hours in a cab when the people we're talking about are required to be physically fit? All strikes me as someone trying to keep their budget... Martin
