  2. 1. Cost Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

    Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE

  4. 2. Mathematical Optimization of the Tactical Allocation of Machining Resources in Aerospace Industry

    Author : Sunney Fotedar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Capacity planning; Bi-objective mixed integer programming; Robust efficient solutions; Robust optimization; Decision-making.;

    Abstract : In the aerospace industry, efficient management of machining capacity is crucial to meet the required service levels to customers (which includes, measures of quality and production lead-times) and to maintain control of the tied-up working capital. We introduce a new multi-item , multi-level capacitated planning model with a medium-to-long term planning horizon. READ MORE

  5. 3. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

    Author : Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
    Keywords : Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. READ MORE
