DEA for nonhomogeneous mixed networks

摘要: Abstract Practically, systems contain a set of subunits each which has inputs and produces outputs. Conventional data envelopment analysis (DEA) ignores the operations individual in system considers as black-box. Recent DEA studies developed to investigate internal structures examine interrelationship components within either with serial or parallel mixed structure. Nevertheless, many practical settings assumption identical outputs may not hold among components. As an example, case plants, various product lines manufactured by different captures idea. This paper proposes network DEA-based methodology address problem nonhomogeneity where operate The layers overall efficiencies can be evaluated through our proposed methodology. To show applicability models, we then use models hypothetical set.
