Models have been widely used in software engineering to support the communication among stakeholders, the analysis, and the guidance in the overall development process. Software models can be used as blueprints in the development process or function as executable models to drive the automated generation of software artefacts.

Modeling has now also become important for systems engineering, that aims to adopt a holistic and systematic approach for designing and managing complex systems. Systems engineering is an interdisciplinary approach and thus imposes different requirements on modeling system artefacts.

In this talk I will discuss the current state of modeling in systems engineering and elaborate on the requirements and need for model-based and model-driven systems engineering.

Search-Based Generalization and Refinement of Code Templates Several tools support code templates as a means to specify searches within a program’s source code. Despite their ubiquity, code templates can often prove difficult to specify, and may produce too many or too few match results. In this presentation, we present a search-based approach to support developers in specifying templates. This approach uses a suite of mutation operators to recommend changes to a given template, such that it matches with a desired set of code snippets. We evaluate our approach on the problem of inferring a code template that matches all instances of a design pattern, given one instance as a starting template.


Güner Orhan, Aselsan

There has been a considerable effort in definition and implementation of models in a large category of application domains and as such many useful models are readily available for use. Using models in various domains creates its own problems. Firstly, due to the complexity of the domain of interest, the complexity and size of the models can be very large. Secondly, models may be configured in many different ways depending on the quality attributes and contextual parameters, which may be implicitly defined in models. Finally, due to possible configuration of models, it may be difficult for software engineers to determine which configurations serve the purpose more. To deal with such problems, we have developed a workbench called Optimal Modeling Language (OptML) framework to represent certain quality attributes and contextual parameters as a separate model and to guide software engineers to determine the optimal configurations with respect to these attributes and parameters. In this talk, he will show the details and explain the benefits of this framework using a state-of-art example.


Ali H. Dogru, Middle East Technical University

This talk introduces a compositional approach where variability resolution is the most important activity for software development. A matured software product line infrastructure is assumed to be present.  Specific expectations from the infrastructure suggests a reference architecture that includes an executable process model for the top-level flow mechanism for the applications, and other software assets that are invoked by this process model.  Variability causes configurations for the process model and the other software assets, that are usually software components.  A configuration request for the process model can initiate further configuration requests in all the infrastructure, including the process model itself. The automatic propagation of further configuration is due to the constraints in the feature level or more technological levels.  The effort is towards the establishment of variability centric system development.  Resolution of variability initiates two kinds of activities for generating the executable system:  1- configuration of the assets due to their having been prepared for a prescribed set of options and 2- model driven generation corresponding to the option.

TOBB ET University and University of Twente

More and more cities adopt the concept of smart cities to manage their processes and to satisfy increasingly sophisticated demands of their citizens. Unfortunately, due to the complexity and lack of effective support by current infrastructures, developing smart-city systems is a very tedious task. This talk identifies 6 categories of challenges as possible obstacles in the cost-effective realization of smart-city systems. Within a few months, as a joint work between the University of Twente and TOBB ET University, 5 PhD projects will be started to address the problems using the principles of model-driven engineering.

Mehmet Aksit

Dr. Aksit and the members his group have contributed to various topics in software engineering, such as programming languages, software design, application frameworks, software quality attributes and university-industry cooperation. As for programming languages, the group has developed one of the first aspect-oriented languages called Composition-Filters. Also, a language that can explicitly represent emergent behavior has been developed. The group has introduced fuzzy-probabilistic techniques for modeling uncertainty in software design processes. Various methods and techniques have been defined to enhance certain quality attributes of software such as  adaptability, evolvability, documentability, availability, traceability, relevancy, energy reducibility and  schedulability. Accordingly, multi-criteria trade-off techniques have been introduced to optimize software architectures. Since 2011, the group has been developing new company maturity models and processes so that companies can conscious about the capabilities and competences they need. In 2017, Dr. Aksit has received the SDPS Priscilla and Raymond T. Yeh Award for Lifetime Achievements in Software Research, Technology Innovation or Engineering Education. Currently, Dr. Aksit is establishing a research center on Smart Cities under the auspices of the TOBB-ET University in Ankara, Turkey.
