Multi-domain simulations introduced in product development process

Computer-based modelling and simulation assists in developing an idea into a product and in the improvement of the properties of the existing product. This improves the competitive ability of the company and shortens the path of new innovations from the idea to the market. Increasing requirements for existing products calls for e.g. environmental-friendliness, cost-orientation and adaptability. Using modelling and simulation it is possible to improve product life cycle cost and usability. This paper describes results of the project that included development of simulation-based design process and particularly application of computer simulation tools and methods on this process. This research studies improvement of simulation-based product development models with a standardized IDEF0-flowchart. IDEF0-flowchart is a standardized, purpose-built tool for modelling decisions, functions and actions in an organisation or a system. At first, six widely recognised product development process models were chosen as the basis of the research. In next stage, a series of interviews of design project leaders were carried out in five different Finnish companies manufacturing mobile working machines, and the present practise of product development process was presented. Thereafter, the simulation-based product development process was modelled. The large case study with the real product model data of a mobile working machine gave input to the simulation-based product development process model.
