“…PBCM was developed for analyzing the economics of emerging manufacturing processes prior to investment [19] and extended to show the implications of alternative design specifications and process operating conditions on production costs [11]. Today, process-based cost models have been used to assess material, design architecture, and process decisions ranging from composite automobile body production and assembly [20,21] to photonic and electronic semiconductor chip design [22][23][24][25], to printed circuit board and optoelectronic transceiver assembly [24,26,27] and packaging [28,29].…”

Additive manufacturing (AM) is increasingly of interest for commercial and military applications due to its potential to create novel geometries with increased performance. For additive manufacturing to find commercial application, it must be cost competitive against traditional processes such as forging. Forecasting the production costs of future products prior to large-scale investment is challenging due to the limits of traditional cost accounting's ability to handle both the systemic process implications of new technologies and the cognitive biases in humans' additive and systemic estimates. Leveraging a method uniquely suited to these challenges, we quantify the production and use economics of an additively manufactured versus a traditionally forged GE engine bracket of equivalent performance for commercial aviation. Our results show that, despite the simplicity of the engine bracket, when taking into account the part redesign for AM and the associated lifetime fuel savings of the additively designed bracket, the additively manufactured part and design is cheaper than the forged one for a wide range of scenarios, including at higher volumes of 2000–12,000 brackets per year. Opportunities to further reduce costs include accessing lower material prices without compromising quality, producing vertical builds with equivalent performance to horizontal builds, and increasing process control so as to enable reduced testing. Given the conservative nature of our assumptions as well as our choice of part, these results suggest that there may be broader economic viability for additively manufactured parts, especially when systemic factors and use costs are incorporated.

“…This is the reason yield must be an integral part of the costing approach. The ability of designers to rapidly evaluate different design alternatives with respect to cost and quality would have an affect of increasing the number of design alternatives generated [6,7]. Moreover, the model encourages the search for small changes in design parameters that may have large impact on costs.…”

“…The layout and routing design phase requires a considerable time commitment from designers. Designers often have insufficient time to investigate many design alternatives because they must spend substantial amount of time to do layout and routing in order to obtain the necessary data to do cost analysis [6,7]. This paper attempts to address these concerns by developing an activity-based cost model for PCB fabrication that can be used early in the design process, prior to the layout and routing phase.…”

Electronic products are built in a competitive environment that demands constant miniaturization, increased functionality of each new generation of products, and compressed design cycles in order to be the first to market with a new product. One repercussion of these business conditions is the designer often does not have time to adequately explore all the design alternatives and select the best alternative. Tools are needed to aid the designer in evaluating the design early in the product development phase. Often reliable estimations of product cost are either lacking early in the design process or difficult and time-consuming to obtain. To address these problems an activity-based printed circuit board (PCB) cost estimation model is developed that estimates PCB cost based on the design parameters. The activities are defined so that the design decisions become the cost drivers and thus enable the cost estimation model to be utilized early in design process when sufficient time remains to make design changes. The cost model is used to rapidly compare different PCB design alternatives and lets the designer assess the impact of their decisions on final cost and aid the designer in generating lower cost alternatives. Analysis of the cost model reveals important relationships between design parameters and cost. The cost model is described and illustrated using a design example.

“…Earlier analytical tools were unable to secure the issue of uncertainty in decision making process. The main issue is that the effect of decreasing one or more key factors, simultaneously increasing one or more other key factors in design projects [26]. The emphasis on 'trade-off' solutions in traditional problem solving practice often means that designers are rarely explicitly aware that conflicts exist.…”

The research carried out to identify ways in which tools and methodologies fromTheory of Inventive Problem-Solving (TRIZ) to solving gaps within the Design-To-Cost (DTC)strategy in product concept development. The aim was to develop an implementationframework for DTC improving product cost and at the same time increase the productinnovation. The research paper reviews TRIZ methodology that has potential to be appliedfor cost reduction initiatives, followed by a discussion of the DTC strategies that commonlypracticed in the various industries. The proposed new DTC implementation framework withTRIZ tools is developed and the research paper concludes with a case study using the new DTCFramework.
