as well as the prime productivity stages. This procedure is capable of ensuring
the preservation of the structure’s overall cost-effectiveness by concentrating on
occupant contentment, equipment dependability, and competent management. In
operation and maintenance terms, competent management usually signifies activities that include arranging equipment and enhancing energy and comfort-control
tactics in order to ensure that the equipment only functions to the extent required in
order achieving its deliberate task. Furthermore, maintenance actions require physical examinations and caring for the equipment. When these tasks are methodically
conducted, it results in increased reliability, minimization of equipment degradation
and preservation of energy productivity.
With consumers expecting their suppliers to be more involved with the continuous
operation of their equipment, the Operation and / or Maintenance (O&M) contracts
have increased in popularity. Nevertheless, O&M contracts are extensive, and have
been utilized in various situations, where each association has their own perspective
on what is actually included in the contract. Such viewpoints can lead to misunderstanding, whether it is in the tendering phase or during implementation of the
contract, hence provoking disagreements between the customer and contractor over
accountability of certain elements of the O&M contract.
15.8 Methodology and Application
PROMETHEE is one of the effectively used multi-criteria decision-making methods
that was originally developed by (Brans and Vincle 1985) and (Brans et al. 1986) in
the late 1980s. When there is uncertain data about the parameters of the alternatives,
the PROMETHEE technique is not applicable for the evaluation. In such cases,
the-fuzzy based PROMETHEE method allows experts to describe these conditions
using fuzzy input data. Recently, a number of different application of this hybrid
technique have successfully been made by Geldermann et.al. 2000, Chou et. al.
2007 and Goumas and Lygerou 2000. Detailed information about the fuzzy based
PROMETHEE technique has been presented in the study conducted by (Ozsahin
et al. 2017). In order to process the data of the public private partnership contract,
the triangular fuzzy scale has been used (see Table 15.1).
