DesignandProductionPlanning The aim of the course is the design and the development of a new product, by implementing a set of methods aimed at bringing the following functions of an enterprise: 1) Design 2) Manufacturing 3) Marketing Each enterprise function is considered like independent and not integrated. Even if the design of a new product is a complex task, it did not require a revision process, due to the low enterprise interaction. MarketingProductionDesign The engineers define a new product The production manufactures it The market sells it! Traditional View Aim 9/26 these functions are central to the product development

The term model is used to refer to both analytical and physical approximations of the products.

- 25. Conclusions A first experience on teaching, at university level, the basic concepts of HyperMesh Desktop was presented The aim of the proposed activity was to provide a tool which the students could use for finding optimized model specifications Simple linear static, normal modes and buckling analyses were carried out from each group The code interface and the different steps to follow for properly setting simulations was not easy to introduce and to explain in the course The most motivated students exceeded the initial settings by proposing numerical models with growing difficulties For the future years, the idea is to dedicate more hours to the code learning (i.e. OptiStruct Optimization will be introduced over the next academic year) 2625/
