title = "SIMPRO Task 2.1: Optimisation of diesel-generating set vibration levels with Dakota",
abstract = "In product design and development there is a continuous need to increase effectiveness. Timetables are getting tighter and cost awareness is of utmost importance. Product design process includes complicated analysis phases and the effective use of computer resources is demanded. Computational power is increasing all the time and at the same time the hardware costs are decreasing. Automatization of the analysis processes is the key factor if one wants to meet the demanding requirements in product design and in the same time to take all the computational possibilities into effective use. The increase in the computational power makes it also possible to take advantage of the numerous optimisation methods that are available. There exists several commercial optimisation software in the market as well as free software based on open software licenses. Moreover, easy to use and learn scripting languages are coming increasingly part of many analysis software. All these factors give great possibilities to develop automatic simulation systems incorporated into optimisation algorithms and thus providing an effective tool in designing better products and in the development of entirely new products. Automating demanding computational work is a key factor in the utilisation of opti-misation methods. Automatic structural analysis systems give many benefits in the design of existing products and also in the design of new products. Modern and flexible analysis soft-ware combined with effective computer hardware and connected together with sophisticated and easy to program scripting languages makes it possible to develop wholly automatic and reliable calculation processes. These processes can then be integrated within optimisation algorithms thus enabling product optimisation and control of the inevitable uncertainty in model parameters. In this work such an automatic calculation engine that can be used in structural vibration analysis is presented. It has been connected to general optimisation soft-ware. Three different product optimisation cases are described and the results are compared.",
