The aim of the ACOSAR project is to elaborate a standard for integration of RT-Systems into (co-) simulation environments. The overall work to be performed is separated into seven technical work-packages (WP1-7) and two organizational related work-packages (WP8-9). The Work Breakdown Structure including the major work-package interactions are illustrated in the figure.
For a holistic analysis of the problem at hand all project partners embracing (co-) simulation tool vendors, RT-System providers, system/software suppliers, engineering service providers, end-users, research institutes and members involved in standardization committees (e.g. FMI) are coming together in WP1 in order to find a common consensus on open system architecture requirements for an advanced co-simulation interface (ACI). On this solid basis methodologies for low-effort integration of RT-Systems (WP2) into (co-) simulation environments will be established, mainly driven by end-users, engineering service providers and model-based system engineering experts. Additionally, resulting WP1 ACI requirements are mapped to the individual component work-packages to elaborate specifications for an interoperable standardized simulation tool interface (WP3), an interoperable standardized RT-System interface (WP4) and an interoperable communication protocol (WP5) for sharing relevant information in a standardized way. Simulation tool vendors (mainly involved in WP3), RT-System providers (mainly involved in WP4) and partners, which work on the communication protocol (in WP5), specify and prototypically implement application programming interfaces (APIs) in accordance to standardization committees (e.g. FMI) to enable a seamless integration into existing standards. Assembling the results out of WP2-5 in WP6 will lead to the overall advanced co-simulation interface (ACI), which serves as basis for application to industrial and scientific use-cases and the elaboration of an ACI pre-standard. ACOSAR project partners along the value-chain are involved in specific ACI application use-case scenarios in WP7.
From a project management point of view the work is separated in domain-specific parts to foster an efficient and slim progress of work. To keep a manageable communication and organizational effort cross work-package interactions are not envisaged, except for project management WP9. The work packages WP1, WP6-8 are of integrating character - smaller cross-country working groups are planned within WP2-5.
