The 6 companies achieved optimum efficiency in min-input model do achieved optimum
efficiency in max-output model. There are Kobay, Lityan, LKT, Maxis, Genting and YLI. Table
4.12 showed that max-output model gave higher efficiency value. ACPI and AIC have 75.4 %
and 74.12% of efficiency in Max-output model whereas in min-input model, they got 26.76%
and 24.55% of efficiency respectively. This result revealed that it is easier for those inefficiency
company to improve and become efficiency company if they follow maximize output approach.
