There are many ways to recover engine waste energy. But which way is the most suitable or feasible ways in future? This is belongs to a multi-criteria decision-making (MCDM) process. Existing methods for project selection does not reflect interdependencies of criteria and candidate methods. Consideration of criteria interdependencies enables valuable cost savings and great benefits to engine and environment. When these problems are evaluated, it is necessary to collect group opinion because the interdependence relationship among criteria is known and it is very important to consider the criteria for the problem solving and decision-making. In order to collect group opinions for interdependent project problems, expert interviews are conducted. Analytic network process (ANP) is applied for measurement of the dependency among the strategic factors, which can help engineer determine their decisions. (1) It is found that thermoelectricity technology is the most suitable method to recovery waste energy in future and the ANP technique is useful as a decision judgment tool.
