Highland politicians plan to continue campaigning to keep fire and police control rooms open.
Labour MSPs claimed the “weighting” given to the different control rooms did not present a true picture of the importance of the fire and rescue service centre to the north.
Rhoda Grant MSP said the options appraisal report to be presented to the board in Dundee on Thursday was “highly subjective” and gave an “arbitrary weighting” that made buildings more important than staff.
“We all know that staff are the greatest asset of any organisation,” she said.
“This is not a done deal and we hope the board will interrogate this report and base their decisions on factual evidence rather than supposition.”
Highlands and Islands Labour MSP David Stewart said: “The options appraisal demonstrates a lack of knowledge of the building at Inverness which has the capacity to house increased numbers of staff. Because of this the Inverness Control Room attracts a lower score.”
Councillors were also dismissive of the fire boards recommendations.
Independent councillor Thomas MacLennan, Fort William and Ardnamurchan, said: “It would be extremely disappointing to lose this element of reasonably local knowledge for the Highlands in terms of pronunciation and where places are.
“I really do feel that this emergency response should be kept relatively local to the Highlands.”
Liberal Democrat justice spokeswoman Alison McInnes said: “It is not an exaggeration to say that this is a dark day for Scotland’s emergency services. I have already been contacted by staff who have told me of their devastation at the proposed closures.
“This confirms that Justice Secretary Kenny MacAskill has stood by and done nothing while highly regarded local emergency police and fire services are dismantled.”
Terry Whyte, Fire Brigades Union officer for the north, said he had yet to see a business case that would support closure.
“Fire control is an integral part of the fire service, they are a front line service and we don’t see that as any different from fire fighters,” he said.
“We are seeking to maintain all, or as many fire control rooms as possible.”
Councillor Margaret Davidson, who represents Aird and Loch Ness, said she was disappointed at the decision to close the Inverness police control room.
She said: “People will feel less safe, I am sure of that. This is what we worried about before the single force was introduced.
“The lack of local knowledge is fairly concerning. We have two places called Farr in Highlands – one in Caithness and one in Inverness-shire.
“Lots of areas will have that sort of problem, but in Highland we have it in spades.”
