Our intention with compiling this Special Issue for Engineering Computations was to cast light on the advancements in terms of the methods and tools for modelling products and systems. It is well known from the literature that there are many new research problems and open issues concerning complex product and system modelling dueto architectural and operational complexities, as well as to methodological deficiencies and limitations. They can prevent providing a purposeful and effective support for advanced engineering activities. For instance, the development of testable concepts or design variants may be blocked; insightful structural or behavioural analysis may be obstructed; or the product manufacturing and real-life operations cannot be simulated or even realized. Though some of the mentioned challenges may not belong to the front line of scientific research, they need to be resolved in order to support the current engineering practice.
