The model driven software development (MDSD) paradigm is gaining momentum in developing extensive business software applications. With MDSD it can be carried out a significant contribution towards the key factors of success which are exibility and adherence to delivery dates as well as efficient maintenance and adaptability. With AtomsPro that is introduced here we consequently integrate aspects of domain modelling and software architecture as well as clear and understandable means to enable domain experts to take an active role in the software development process. The challenging aim is to increase the overall ratio of code generated in the development process of enterprise applications by at the same time preserving abilities for efficient maintenance. Hence, we have chosen a fruitful cooperation with several involved project partners.
Speeding up Discrete Event Simulations (DESs) is a broad research field. Promising Parallel Discrete Event Simulation (PDES) approaches with optimistic and conservative synchronisation schemes have emerged throughout the years. However, in the area of real-time simulation, PDESs are rarely considered. This is caused by the complex problem of fitting parallel executed DES models to a real-time clock. Hence, this paper gives an extensive review of existing conservative and optimistic synchronisation schemes for PDESs. It introduces a metric to compare their real-time capabilities to determine whether they can be used for soft or firm real-time simulation. Examples are given on how to apply this metric to evaluate PDESs using synthetic and real-world examples. The results of the investigation reveal that no final answer can be given if PDESs can be used for soft or firm real-time simulation as they are. However, boundary conditions were defined, which allow a use-case specific evaluation of the real-time capabilities of a certain parallel executed DES. Using this in-depth knowledge and can lead to predictability of the real-time behaviour of a simulation run.
