2)    Output-oriented

3)    Non-oriented


RTS to measure efficiency

2)          Variable returns to scale (VRS)

3)          Non-increasing returns to scale (NIRS)

4)          Non-decreasing returns to scale (NDRS)

5)         Decomposition of Efficiency or TFP Index


TFP Index: Malmquist Index and Hicks-Moorsteen Index (also called HMB Index)

a)           Adjacent Malmquist

b)          Fixed Malmquist

c)           Global Malmquist

d)          Sequential Malmquist

e)           Window-Malmquist (Adjacent)

f)           Window-Malmquist (Fixed)

g)           Global with Sequential Malmquist

TFP index decomposition: Efficiency Change (catch-up), Technological Change (frontier shift), Scale Efficiency Change, biased Technological Change, TC=OBTC*IBTC*MATC (Fare et al 1997)

Three types of indices can be computed: Index(t-1, t); Index (t-n, t) : n is user-defined; Index (t0, t): t0 is the initial period.


Window DEA

4)        Cross efficiency model

Second-stage methods are available:

Minimize/Maximize the trade balance of other DMUs as a whole

a) Blanket Benevolent (Type I in Doyle and Green 1995)

b) Blanket Aggressive (Type I in Doyle and Green 1995)

Maximize/Minimize the cross-efficiency of other DMUs as a whole

c) Blanket Benevolent (Type II in Doyle and Green 1995)

5)        Game Cross Efficiency model: Nash Equilibrium model (Liang, et al 2008; Wu, et al 2009)

6)        Undesirable outputs, desirable inputs

7)        Nondiscretionary input/output model

8)        Preference (weighted) model

9)        Restricted multiplier model (assurance region model, trade-offs between inputs and outputs)


What's more important, like MaxDEA Ultra, MaxDEA X also provides nearly all possible combinations of the above models.
