Examples and classification of performance measures in SCM

Depending on the scope of the simulation study, performance measures should be chosen w.r.t. to the aggregation level as well as managerial impact. Ideally, an SC evaluation 

Robustness is often an important feature, in particular when an objective s variation depends on the configuration. Robustness can be measured in various ways, e.g. by con- 

FYom the deductions above it can be concluded that simulation studies on SC configuration put focus on multiple objectives/performance measures which depend on the configuration x. The configuration and its performance affect the total cost and/or total profit. The combination of a configuration and its performance z = (x,y) is called a constellation. In simulation studies on SC configuration typically a set of efficient constellations is sought. Per definition an efficient constellation is not dominated by any other constellation. A constellation z = (x,y) is (strictly) dominated by a constellation 

) and strictly preferred for at least one variable (3/ such that zy 

The set of efficient constellations is denoted by To sum up, there are two cases to be distinguished in simulation optimization If a unique objective can be defined and calculated, an optimal configuration is searched for. In case of multiple objectives, the set of efficient constellations has to be determined. Both tasks are hindered by the following properties of simulation models
