“…CRs are mapped to technical attributes in QFD to achieve higher customer satisfaction. [39][40][41][42] In the design field, QFD tool is often used to select potentially important CRs, and AHP pairwise comparison matrix is used to further identify and prioritize CRs. Based on these two applications of QFD and AHP, a comparative study found that the prioritization matrix method is preferable when time, cost, and difficulty are the main concerns in product improvement, whereas the QFD method is the better choice when accuracy is the main requirement.…”

Product customers often have varying preferences because they have different environmental and social habits backgrounds’ requirements “customer diversity requirements.” Even for a particular product used in specific place, the requirements of product stakeholders are often differed. It is a challenge to adapt diversity requirements to concepts design of products to satisfying different customers. To address the customer diversity requirements issue, after the analysis of customers information is completed, customers are classified according to their diversity. Then, customer requirements (CRs) and engineering specifications (ESs) that satisfy the CRs are determined. The priorities of CRs are calculated with analytical hierarchy process (AHP) involving a pairwise comparison matrix in the first step and fix-sum method in the second step. Quality function deployment (QFD) relation matrix is utilized to form the relationships intensities of CRs and ESs. ESs satisfaction degree values obtained concerning computation of CRs priorities calculated via AHP, while ESs target degree values obtained concerning computation of CRs priorities calculated via fix-sum method into QFD relation matrix. ESs satisfaction degree compared with ESs targets degree to measure the satisfaction for each customer target individually. The decision on whether the concept design needs further development or modification is made based on the comparison results. A case study of the application of this approach is presented to illustrate the possibilities of the technique in developing or modifying concept design according to customers’ life environmental and social habits background “diversity requirements.” The case proved that technique can adapt products to different environments and that products used by existing customers can be used for new customers or markets (product globalization) instead of being confined to one location. Moreover, the approach is very useful in clarifying the objectives expected by customers for specifying the development or modification of a product concept.

“…By applying different matrix operations, the design activities can be organized and analyzed [10]. One example of a matrix-based method is the House of Quality from Quality Function Deployment (QFD) where customer requirements are mapped to engineering characteristics [11]. Other matrix-based methods include the incidence matrix [12], the design structure matrix [13], and the function impact matrix [14].…”

In order to integrate two single-function products to a multifunction product, a matrix-based conceptual solution generation approach is proposed in this paper. In the approach, the overall function of a single-function product is decomposed into a number of subfunctions. The sub-functions are described by the functional basis and are used to construct the function model of the singlefunction product. By analyzing the function models of two single-function products, a functional similarity matrix is constructed based on the quantified similarity indexes of two sub-functions. For indicating the relationship between the sub-functions and the components, a function-component matrix of each single-function product is constructed, and then a component-component matrix of two single-function products can be acquired by multiplying the function-component matrix and the functional similarity matrix. There are three kinds of components' relationships in the component-component matrix, namely, no-correlation, simplecorrelation, and complex-correlation. The components of two single-function products can be, respectively, removed, modified, and reserved according to the different correlation relationships, and a design solution of a new multi-function product can be obtained by combining the reserved and modified components. As a case study, a conceptual solution of a new shaver is acquired under the help of the provided approach.

Reverse Engineering Risk: Converging Medical Standards for Improved Systems Engineering

Early systems engineering and active risk management have been credited with improving the Department of Defence's (DoD) ability to deliver on cost, schedule, and technical requirements. The Government Accountability Office (GAO) continues to identify risk management of critical technologies as a key contributor in schedule delays and cost overruns. A review by GAO of key DoD programs has found that specifically an increase in technical scope, interoperability requirements, and advanced technology integration has been the root cause for many of these delays. To address these findings, DoD mandates Technology Risk Assessments (TRA) of key technologies at specific milestone gates. Unfortunately, the tools and metrics supplied for the TRAs continue to rely on dated concepts that have failed to provide the objective insight into modern technology integration and interoperability requirements. This paper proposes a new approach for technical risk management that borrows from concepts in the medical field that treat risk management as a top‐down integrated system concept.
