Abstract: An embodiment of the present invention discloses a method for the computer-aided determination of the dependencies of a plurality of modules of a technical system, especially of a software system. Every module of the system has a known, first consumption of resources. The first consumption of resources of at least one of the modules is modified according to a predetermined criterion, thereby obtaining a modified system. The modified system is executed. A second consumption of resources is measured for every module of the modified system, the consumption resulting from the modification of the first consumption of resources of the at least one module. An analysis of the second consumption of resources of a respective module and the predetermined criterion is used to determine whether there is a dependency between the respective module and the at least one module that is characterized by the modified consumption of resources.

Abstract: A method is disclosed for the computer-assisted performance analysis of a data processing system, wherein a program code with a plurality of code parts is running. During the execution of at least one embodiment of the method, one or more parts of the code parts are at least varied once while using a functionality creating a variance in regard to at least one criterion to be evaluated. The data processing system is executed with the varied code part and parts multiple times. A variance of the at least one criterion to be evaluated of the varied code part or parts, or of all code parts of the program code is determined. Finally, a covariance resulting from the variance is subjected to a multivariant analysis.
