•We consider the distribution of composite indicator values in the weight vector space.•Mean (μ) and standard deviation (σ) synthesize the distribution.•Measurement of local and global efficiency in the σ−μ space is introduced.•Static or dynamic multiple efficient frontiers can be graphically repres...
