The industrial cyber-physical production system contains a variety of heterogeneous devices and models, which increase the complexity of system design, particularly in software programming. Although the proposed model-driven engineering (MDE) is applied to industrial automation for this issue, the inherent complex dependencies and constraints between models and the availability of suitable tools for code generation limit the application of the model-driven approach in practice, especially as the system becomes more enormous. The component-based design (CBD) approach, which is a bottom-up approach, in contrast to the MDE that is top-down, is proposed to manage the complexity of software aspect based on the idea that building a system from existing components instead of the scratch. However, CBD can't provide the whole system model, so other ways should be adopted to design the system structure in advance. This paper presents an integrated design approach based on the combination of CBD and MDE to realize auto-design for cyber-physical production systems.

In this paper, we briefly describe a general theory of software used in order to model and predict the current and future quality of softwaresystems and their environment. The general theory is described using a class model containing classes such as application component, business service, and infrastructure function as well as attributes such as modifiability, cost, and availability. We also elaborate how this general theory of software can be extended into a general theory of softwareengineering by adding engineering activities, roles, and requirements.

Hard real-time systems are found in many critical embedded applications, for example aeroplane flight control, industrial production line control, and so on. The safe scheduling of tasks in these hard real-time systems is crucial to their correct operation, but the hard constraints of this type of scheduling reduce the responsiveness of the systems. In this paper we show the application of runtime analysis in informing the design of hard real-time embedded systems by allowing scheduled tasks to be dynamically re-ordered to improve the average responsiveness, while still meeting the hard constraints imposed by the system. The technique is semi-automated, and uses the reduce computer algebras system to precalculate a symbolic form of the runtime of scheduled tasks. The symbolic form is used to modify the source code of the scheduler.
