A framework for cost evaluation in product service system configuration

Configuration systems are increasingly used as a means for efficient design of customised product service systems (PSS) to satisfy diverse customer needs. Cost evaluation is thereby important to assist the configuration engineers in making decisions on feasible configuration solutions. However, little research attention has been received until recently. To fill this gap, this paper contributes in developing a framework for cost evaluation in PSS configuration. A holistic view of PSS configuration, the three-dimensional PSS cost element, and a life cycle-oriented cost evaluation approach are successively proposed. The framework is thereby established with a number of parts, including the preparatory stage, the evaluation stage and the configuration stage. A pump PSS is illustrated to validate the developed framework. Four feasible configuration solutions in one configuration activity are evaluated and compared. The configuration engineers are thus assisted with the decision on selecting the one with the least cost.

A generic tool for cost estimating in aircraft design

A methodology to estimate the cost implications of design decisions by integrating cost as a design parameter at an early design stage is presented. The model is developed on a hierarchical basis, the manufacturing cost of aircraft fuselage panels being analysed in this paper. The manufacturing cost modelling is original and relies on a genetic-causal method where the drivers of each element of cost are identified relative to the process capability. The cost model is then extended to life cycle costing by computing the Direct Operating Cost as a function of acquisition cost and fuel burn, and coupled with a semi-empirical numerical analysis using Engineering Sciences Data Unit reference data to model the structural integrity of the fuselage shell with regard to material failure and various modes of buckling. The main finding of the paper is that the traditional minimum weight condition is a dated and sub-optimal approach to airframe structural design.     

Minimum cost tolerancing under uncertain cost estimates

This paper presents Cost Tolerance Sensitivity Analysis (CTSA), a new method of determining which features are critical and non-critical early in the design phase when cost information is uncertain. The method utilizes minimum cost tolerancing methods combined with designed experiments to determine which features are sensitive or insensitive to uncertainties in the cost-tolerance curve estimates. The paper also discusses novel aspects that must be considered in estimating cost tolerance curves in the early design phases. The method is demonstrated on the case study of a windmill transmission. The results show that the method could successfully identify critical and non-critical dimensions, both cost and tolerances must be considered simultaneously, and examination of near optimal solutions improves the results.     

Cost Prediction of a Turbofan Engine Using the Robust Partial Least Squares Method

In recent years,the cost of engines has become increasingly important to engine manufacturers,who are consistently faced with major problems on how to reduce cost to a minimum.Cost has become a decisive factor for aircraft design.To control the continual rapid increased cost,engine cost prediction is indispensable early in the design phase.But the cost data of an aircraft engine is small;we introduce the Robust Partial Least Squares Method in solving this problem,and reducing or removing the effect of outlying data points,which is different from the Classical PLS.We use the MATLAB software doing several simulations;results and analysis of a real turbofan engine data set show the effectiveness and robustness of the Robust PLS method.The Robust PLS method can effectively be used to estimate Turbofan Engine cost with reasonable accuracy.
