A Value-Driven Design Approach to Optimize a Family of Front-Loading Washing Machines

Existing research on the design and analysis of front-loading washing machines has primarily focused on maximizing performance of a single product based on specific disciplinary analyses (e.g., vibration, dynamics). This design approach does not necessarily guarantee low costs, high sales, and maximum profit. Moreover, in order to target a variety of different customer needs, washing machines should be thought of and designed as a product family. In this paper, we suggest a value-driven design approach for a family of front-loading washing machines to identify promising solutions based on stakeholder’s preference. To create a value function, the sales volume for front-loading washers is estimated based on sales rank data, and then the net present value (NPV) is formulated by using the estimated sales volume and a demand sensitivity curve derived from the literature and publicly available data. The result shows that we can determine product family design candidates that maximize NPV, performance, and commonality of scalable and platform (i.e., shared) variables in the washer family. We also investigate the effectiveness of reducing the complexity of the value function based on rank ordering and parametric studies of the attributes used to compute NPV.

Purpose The purpose of this study is to research the latest quantitative and qualitative transformations of money and its interaction with the market economy and societies in terms of their influence on the inner nature of money and its transformation from a simple tool to an aim per se, i.e. postmoney. Transforming the perception of the intrinsic value and “soul” of the money into the postmoney, influenced by the rising longevity and wide expectation for the ability to scientifically prolong the human life, will be discussed. This transformation will be confirmed by analysing the results from a national representative sociological survey (panel study with sample size n = 1,000). Design/methodology/approach The author uses the following philosophical methodological approaches – comparative-constructive, phenomenological, cognitive and deconstructive analysis. Findings The objective and qualitative reasons offered by the postmoney theory (PMT) for the transformation of money into postmoney, are related to the being of temporality, as well as to technologization and the sixth factor of production, scientific exponentiality and mental changes in the human being. A current postmoney survey gives a strong base to believe that the perception of an intrinsic value of postmoney changes the shape of a value function – from logarithmic to linear or even stochastic. This is the reason to believe that increasing of a postmoney quantity will lead to a qualitative transformation and psychological increase of postmoney sensitivity. Research limitations/implications The author intends to expand the postmoney survey on the international level so to confirm local findings. Practical implications Postmoney survey might be used as a powerful tool in creating and legalizing non-monistic money based on blockchain technologies and philosophical and socio-economic research of the postmoney issue. Social implications The future of money is of great importance for the exponentiality of the socio-economic environment and societies. Social impact of the money will be inevitably rising in the domain of postmoney perception. Originality/value The author of the current paper coined for the first-time notion of postmoney and now is expanding research developing PMT. As per the best knowledge of the author, shape of the curve of value function was not questioned and believes it might be of help to better understand the money phenomenon.

Initial Research

Though little research has been done in the field of over-design as a product development strategy, an over-design approach can help products avoid the issue of premature obsolescence. This paper compares over-design to redesign as approaches to address the emergence of future requirements. Net present value (NPV) analyses of several real world applications are examined from the perspective of manufacturers and customers. This analysis is used to determine the conditions under which an over-design approach provides a greater benefit than a redesign approach. Over-design is found to have a higher net present value than redesign when future requirements occur soon after the initial release, discount rates are low, initial research and development cost or price is high, and when the incremental costs of the future requirements are low.

White Fathers

Value-sensitive design is an approach that seeks to explicitly center the values of design stakeholders. In doing so, the method provides a rich analytical backdrop in which to explore how participants make sense of values and embody values in their designs. In this study, I explore the broad question of how a value-sensitive design approach can be used to surface, address, and possibly reconcile the similar and different culturally informed ways we make sense of being feminist fathers. Two groups of self-proclaimed feminist fathers, white non-Latinx and nonwhite Latinx, engaged in a value-sensitive design approach to designing technology to support their conceptualizations of feminist fatherhood. Four themes around differences between the groups and the kinds of reflections the participants engaged in are summarized. Based on our findings, I contribute suggestions for adapting value-sensitive design approaches to scaffold certain kinds of reflection around authenticity and interpretation in ways that are more grounded in themes of nondominance.

Exchange Rate Intervention

This paper considers an exchange rate problem in Lévy markets, where the Central Bank has to intervene. We assume that, in the absence of control, the exchange rate evolves according to Brownian motion with a jump component. The Central Bank is allowed to intervene in order to keep the exchange rate as close as possible to a prespecified target value. The interventions by the Central Bank are associated with costs. We present the situation as an impulse control problem, where the objective of the bank is to minimize the intervention costs. In particular, the paper extends the model by Huang, 2009, to incorporate a jump component. We formulate and prove an optimal verification theorem for the impulse control. We then propose an impulse control and construct a value function and then verify that they solve the quasivariational inequalities. Our results suggest that if the expected number of jumps is high the Central Bank will intervene more frequently and with large intervention amounts hence the intervention costs will be high.

Family Evaluation

Specifying components in a product platform and family architecture to support product varieties can be a challenging task for companies. Especially when various viewpoints have to be considered, which include product variety, materials, manufacturing complexity, assembly complexity, average component count commonality, assembly sequence, and late point differentiation. In order to identify or select a product platform and family configuration, evaluation of alternative configurations need to be performed. In this paper several product family evaluation criteria are presented for configuration evaluation. The application of product family configuration evaluation and a design approach is demonstrated using a Computer Mouse family.

Intervention Context

Purpose: The purpose of this paper is to explore whether the four value alignment strategies available to educators (Scaffolding, Balancing, Intervention and Refuge) previously identified in the mathematics education literature comprehensively capture educator value alignment strategies in an intervention context. Design/Approach/Methods: To this end, we analyse semi-structured interview data with two teacher-leaders involved in the Getting Ready in Numeracy (G.R.I.N.) intervention program through a value alignment lens. Findings: We ascertain that a fifth strategy, the Beacon strategy, is needed to describe the range of value alignment strategies employed by educators in the G.R.I.N. program. The Beacon strategy involves the educator digging in and reasserting their expectations until the student behaves in a manner that aligns with the educator’s values. In part it involves the educator being able to recognise their own values and clearly communicating these values to students. Originality/value: This article further explores strategies that educators have at their disposal for aligning their values with those of their students. The uncovering of the Beacon strategy is particularly valuable as it suggests that educators could be purposefully pursuing value alignment even when they do not appear to take any active steps to move further towards their students’ sets of values.
