Abstract [en]

This paper defines the challenges and needs related to Configuration Management of large scale aeronautical simulation systems, where the MBSE approach is a guiding force. The basic problem is to support modeling and simulation of all variants of a product line. The simulation models may be used in (at least) three different contexts; development, verification and training, each with their specific objectives.

Assumptions and basic components of the research issue are as follows: There exists a defined product line. The product line is modeled with respect of

  • Configuration; for certification, delivery, and maintenance in a PDM/PLM context
  • Behavior; for development, verification and training in a simulation context

Configurable simulation models are developed and maintained to represent parts/modules of the product line as well as the environment where the products operate. Each simulation model included in any utilized simulation system can be viewed as a module in a (simulation product) platform. The modular models are stored in a model library for easy access and inclusion in a simulation system. Every model must be configurable in at least three dimensions; representation, usage and implementation. They will represent a specific product within the product family, they will be used in some of the three contexts (development, verification and training) and they will be implemented in a specific simulation platform/architecture.

Management of configurable simulation models in the described context is an increasingly challenging activity. Supporting systems and methods for configuration and integration of models and simulation systems are not mature and do not scale up. To view the model set as a Software Product Line representing the Product Line of the end products is an approach to more stringent map the simulation models to the real product/system. A concept of a structured ConfiguratioN datA object (CNA-string) is introduced as a means to integrate configuration information and to be used for simulation set-up purposes. Application example in the work is the light weight fighter aircraft Saab 39 Gripen.

Abstract [en]

AIRCRAFT DEVELOPERS, like other organizations within development and manufacturing, are experiencing increasing complexity in their products and growing competition in the global market. Products are built from increasingly advanced technologies and their mechanical, electronic, and software parts grow in number and become more interconnected. Different approaches are used to manage information and knowledge of products in various stages of their lifecycle.

"Reuse" and "Model Based Development" are two prominent trends for improving industrial development efficiency. The product line approach is used to reduce the time to create product variants by reusing components. The model based approach provides means to capture knowledge about a system in the early lifecycle stages for usage throughout its entire lifetime. It also enables structured data  management as a basis for analysis, automation, and team collaboration for efficient management of large systems and families of products.

This work is focused on the combination of methods and techniques within;

  • modeling and simulation-based development, and
  • (re)use of simulation models through the product line concept.

With increasing computational performance and more efficient techniques/tools for building simulation models, the number of models increases, and their usage ranges from concept evaluation to end-user training. The activities related to model verification and validation contribute to a large part of the overall cost for development and maintenance of simulation models. The studied methodology aims to reduce the number of similar models created by different teams during design, testing, and end-user support of industrial products.

Results of the work include evaluation of a configurator to customize and integrate simulation models for different types of aircraft simulators that are part of a simulator product family. Furthermore, contribution comprises results where constraints in the primary product family (aircraft) govern the configuration space of the secondary product family (simulators). Evaluation of the proposed methodology was carried out in cooperation with the simulator department for the 39 Gripen fighter aircraft at Saab Aeronautics.

Abstract [sv]

FLYGPLANSTILLVERKARE LIKSOM andra industrier inom utveckling och tillverkning, hanterar ökande komplexitet i sina produkter och upplever en större konkurrens på den globala marknaden. Produkter byggs från allt mer avancerad teknologi. Ingående delar av mekanik, elektronik och mjukvara växer i antal och blir allt mer integrerade. Olika metoder används för att hantera information och kunskap om produkter i olika steg av dess livscykel.

”Återanvändning” och ”Modellbaserad utveckling” är två tydliga trender för att öka effektiviteten inom industriell utveckling. Produktfamiljer används för att minska ledtider när man skapar varianter av produkter genom att återanvända färdiga komponenter. Modellbaserade metoder ger möjlighet att tidigt i livscykeln samla kunskap om ett system för att användas under hela systemets livstid. De ger också strukturerad hantering av data som grund för analys, automatisering och samarbete mellan utvecklingsteam, vilket är en förutsättning för effektiv hantering av komplexa system och produkter.

Detta arbete är fokuserat på en kombination av metoder och tekniker för;

  • utveckling som baseras på modellering och simulering, och
  • (åter)användning av simuleringsmodeller.

Med ökande beräkningsprestanda och effektivare metoder/verktyg för att bygga simuleringsmodeller så ökar antalet modeller och deras användning spänner allt från konceptvärderingen till utbildning av slutanvändare. Arbetet med verifiering och validering av simuleringsmodeller utgör en stor del av deras totala utvecklings- och underhållskostnader. De studerade metoderna syftar till att minska antalet liknande modeller som hanteras av olika team för olika syften, som till exempel; utveckling, verifiering och som stöd för slutanvändare.

Resultat av arbete inkluderar utvärdering av en konfigurator för att välja, integrera och anpassa simuleringsmodeller för olika typer av flygplanssimulatorer i en simulatorproduktfamilj. Dessutom bidrar arbetet med en metodik där begränsningarna i den primära produktfamiljen (flygplan) begränsar konfigurationsutrymmet för den sekundära produktfamiljen (simulatorer). Utvärdering av den föreslagna metoden har genomförts i samarbete med simulatoravdelning för flygplan 39 Gripen på Saab Aeronautics.
