One way, if the string has always those contents, and only the numbers change:

x,y = ci_id_asso_type.match(/id(\d+)service_desk_ci_association_type_id(\d+)/).captures.map
{|n| n.to_i}

BTW, I would do the loop like this:

1.upto(total_ci_id_asso_types) do |count|
         v = "sd_ci"+"#{count}"
         ci_id_asso_type=params[:"#{v}"]
end

or

total_ci_id_asso_types.times do |count|
         v = "sd_ci"+"#{count + 1}"
         ci_id_asso_type=params[:"#{v}"]
end
