The MBS could not be reduced further down than two mechanics, since at that point the
availability of some machines would be zero after they had failed.
The values of machine availability and the annual cost are displayed for a 33.33%
level of the mechanic manpower under the traditional system. After this point the
availability of the machines starts to decrease significantly. It can thus be concluded,
based on the parameters from this consulting study, that approximately 67% of the
manpower will provide an adequate machine availability that is higher than in the
traditional system, with a higher level of mechanic utilisation. In addition, the MBS does
not suffer from major loss in machine availability as long as the manpower is above
30% level. At the same time, there is a constant reduction in total annual cost. In other
words, the management can realise a fall in operating expense without a sacrifice of
service quality through exploitation of the inherent flexibility of the MBS dynamic
allocation of the mechanics.
