Abstract
Simulation technologies provide necessary validation tools for the conceptual design of complex products involving multiple disciplines. A variety of simulation models are developed in specific organizations or enterprises to verify the design plan, while they are hard to be shared and to be reused. Based on the analysis of several typical solutions to share and reuse different kinds of resources, a simulation model design method is proposed to provide a simple implementation of simulation model reuse for cloud-based simulation environment. This paper firstly creates the simulation models' metamodel and ontology for their universal description. Secondly, four rules are proposed to design/reprogram a simulation model into service-oriented form for its interoperability, and the ontology of service-oriented simulation model is established. Thirdly, the way to call one simulation model and the way to compose several simulation models into a simulation process are elaborated. Finally, a simple case of using this method to design an aircraft dynamic model is elaborated, and a prototype simulation system is constructed, and then a simple simulation process is composed to verify the practicability of the method. The result shows that the new design/reprogram method has big advantages on the compatibility, expansibility, and reusability despite the decreasing efficiency.

The design process of modern product is a process in which uncertainties are gradually reduced, and it involves a series of iterative stages mainly including conceptual design, detailed design, simulation analysis, manufacturing, and sale
Advances in Mechanical Engineering simulation model to do a simulation task, because an enterprise cannot have all the simulation models which are available only within some specific organizations or enterprises; (2) sometimes, it is hard to find a suitable simulation model to do a simulation task according to some requirements, because these models are managed out of order; (3) sometimes, it is hard to reuse existed simulation models, because they are programmed to be ran under specific environments; (4) sometimes, it is hard to put some simulation models together to perform a simulation process, because they are interdisciplinary and heterogeneous, and they are programmed by different people in different programming languages at different times
