A paper on our documentation framework for architecture decisions has been recognized as one of WICSA 2014‘s best papers in Sydney. The implementation of the framework as an add-in to Sparx Systems Enterprise Architect was done in a collaboration of the University of Groningen and ABB.
We got a paper accepted at IEEE CLOUD 2014: “We benchmarked three open source timeseries databases (OpenTSDB, KairosDB and Databus) on cloud infrastructures with up to 36 nodes with workloads from realistic industrial applications. We found that at least KairosDB fulfills our initial hypotheses concerning scalability and reliability.”
The latest issue of the magazine “IEEE Software” features our article on architecture sustainability: “At ABB, we’re measuring and tracking the architecture sustainability of a large-scale, distributed industrial control system currently under development that’s based on Microsoft technologies and includes a layered architecture. A former version of the system grew to several million LOC and suffered from architecture erosion and high maintenance costs. We adopted a multiperspective approach called Morphosis to avoid such a situation from occurring again. Morphosis focuses on requirements, architecture design, and source code. It includes evolution scenario analysis, scoring of technology choices, architecture compliance checks, and tracking of architecture-level code metrics. This article reports our experiences with tracking selected sustainability measurements over the course of two years.”
Our summary report from the 2012 GI-Dagstuhl Seminar “Multicore SW Performance Engineering” has appeared in ACM SIGMETRICS Performance Evaluation Review: “In the era of multicore and manycore processors, a systematic more and more crucial to the success of modern software systems. This article argues for more software performance engineering research specically for multicore and manycore systems, which will have a profound impact on software engineering practices.”
Research Directions for Multicore Software Performance Engineering
We got a paper accepted at the Industry Track of the 17th International Software Product Line Conference (SPLC2013) to be held August 26th-30th in Tokyo, Japan: In the paper, we describe how we applied existing domain analysis approaches for software product line engineering and tailored them to include a feature analysis as well as architecture evaluation. We report our experiences from applying the approach in two subdomains of industrial automation.

Paper accepted at ICPE 2013: We introduce a novel model transformation from Use Case Maps (UCM) to the Palladio Component Model (PCM), which enables performance modeling based on an intuitive notation for complex information flows. The resulting models can be solved using existing simulators or analytical solvers. We validated the correctness of the transformation with three case study models, and performed a user study. The results showed a performance prediction deviation of less than 10 percent compared to a reference model in most cases.
Our article on reliability prediction with the Palladio Component Model finally appeared in the November/December issue of IEEE Transactions on Software Engineering.
The latest issue of ABB’s corporate technical journal “ABB Review” features the theme “Software”. With around 3,000 software developers in 40 countries worldwide and impacting about one quarter of ABB’s revenue, there is no doubt that ABB is a major software company. The theme issue provides an overview on some of ABB’s latest activites for embedded, system, and enterprise software as well as software processes. Check out how we prepare our controllers for the multi-core challenge and how we use performance modelling to plan the capacity and software architectures of our back-end IT.
Because much of the software was, until recently, embedded in other products, ABB was not recognized as being an obvious software company. This changed with the acquisition of enterprise software companies such as Ventyx and Mincom, rendering ABB much more visible on the software scene.
New paper accepted at the Industry Track of ICSM 2012 in Trento: “We created a catalog of ”software sustainability guidelines” to support project managers, software architects, and developers during system design, development, operation, and maintenance. This paper describes how we derived these guidelines and how we applied selected techniques from them in two industrial case studies. We report several lessons learned about sustainable software development.”
A new paper was accepted for a working session at WICSA 2012 in Helsinki: “Managing the cost-effective evolution of industrial software systems is a challenging task because of their complexity and long lifetimes. We have applied several recent sustainability evaluation and improvement approaches to the software architecture of a large industrial software system from ABB. We combined our selection of approaches in a lightweight method called MORPHOSIS“.
