SERVICE-ORIENTED ARCHITECTURES: MODELING THE SELECTION OF SERVICES AND PLATFORMS
The Service-Oriented Architecture (SOA) paradigm promises to facilitate the integration of software
services provided by different vendors and thus enables users to benefit from Best-of-Breed solutions.
In order to support software architects we present the Multilayer Standardization Problem (MSP) to
analyze the trade-off between possibly enhanced utility versus higher assembling costs of Best-ofBreed SOA solutions. We implemented a software prototype to support decision makers during the
data input and the subsequent analysis of the solution’s robustness. The MSP for the SOA-case is
formulated as a linear 0–1 optimization model and extends the established Standardization Problem
(SP) by modeling the user preferences and considering varying granularity as well as integration
relationships in addition to communication relationships. These characteristics are common to
numerous systems – thus the general MSP can serve as a basis for further research in this field
