“…Few quantitative cost models exist between the two ends of this spectrum because no suitable method has been found that can deal with multi-fidelity data from multiple levels of product definition (Scanlan et al, 2006). This project aimed to bridge the gap by making use of the synergy effects from using an ABC and a parametric model in conjunction.…”

The first tool presented in this paper is a generic factory cost model that can estimate various costs at multiple levels of any manufacturing plant. The model is activity-based which means that the cost of each manufacturing operation is calculated and then summed up so that the true £-per-hour factory cost rate as well as the exact unit cost (i.e. manufacturing cost) of an unlimited number of different components can be estimated.The second tool is a scalable cost model that estimates the unit cost of future integrally bladed disc (blisk) designs which are used by the aerospace industry in gas turbine compressors. The tool multiplies the machine cost rates, calculated by the factory cost model, by the operation times derived from blisk scaling rules. As the operation times often depend on the number of blades, the disc diameter and other design variables, many scaling rules are based on the correlation between operation times and certain design parameters. Conversely, the remaining process times are constant because they are independent of the blisk geometry. As future process times can only be estimated and the correlation between operation times and design parameters is never perfect, all operation times have uncertainty distributions. These are cascaded through the model to generate a probability distribution of the unit cost.Through the interactive exchange of detailed cost information at the manufacturing operation level as well as extrapolated operation times, the two cost models facilitate design and manufacturing engineering to concurrently optimise blisk designs and manufacturing processes in terms of cost.

“…The methodology was to exploit manufacturing simulation capabilities and PLM solution associated with digital mockup data to obtain real-time cost estimates for a fuselage of a commercial jet. Scanlan, et al, (2006) launched a project called DATUM with Rolls-Royce PLC to establish a prototype system for the creation of a cost model structure to integrate with a design optimisation system using PLM solutions.…”

“…Attempts for a combined cost/weight optimization have been done by Geiger and Dilts [1], Heinmuller and Dilts [2], Kassapoglou [3][4][5], Marx et al [6], Gantois [7], the Rolls-Royce's DATUM project [8], Park et al [9], Edke and Chang [10], and Curran et al [11]. In particular, Kelly and Wang [12], Wang et al [13], Curran et al [14], and Kaufmann et al [15] incorporated the idea of a weight penalty; this weight penalty was applied to balance the tradeoff between manufacturing cost and structural weight.…”

Composite structures can lower the weight of an airliner significantly. The increased production cost, however, requires the application of costeffective design strategies in which cost, weight and the desired laminate quality are taken into account. This paper proposes an optimization framework for composite aircraft structures that minimizes the direct operating cost on a part level. In addition to previous models, a nondestructive testing model is implemented that calculates design allowables of a laminate based on ultrasonic scan parameters. In a case study, the effect of the laminate quality on the direct operating cost is discussed. It is investigated how the permissible flaw size and therefore the scan pitch of a composite laminate can influence the optimal solution in terms of cost and weight; thus, the manufacturing cost, the non-destructive testing cost and the weight of a component can be balanced by optimizing the laminate quality in an early design phase.
