Product Development Cost Estimation in Mass Customization

The ultimate goal of mass customization is to achieve economies of both scope and scale. This goal implies a conflict between customization and economy of scale (or mass production) in the traditional manufacturing paradigm. However, recent developments in computer and Internet communication technologies, concurrent engineering, and modular design methodology provide concepts, methods and technology infrastructure for realizing mass customization. One of the findings from numerous research efforts on mass customization is the use of e-commerce technologies to manage a product development chain that links customers, suppliers and manufacturers together to approach concurrently customized products in a short time and at the low cost level of mass production, i.e., mass customization. To ensure the success of mass customization in a product development chain, a rapid, automatic yet accurate cost estimate and control system is needed. This paper presents a cost index structure, which is a novel data structure, together with two novel cost estimate methods, viz. the generative cost estimate method and the variant cost estimate method, for the development of a semi or fully automatic computer-aided cost estimate and control system in mass customization. Finally, an industrial case is reported in the paper to illustrate the principles and feasibility of the proposed data structure, methods and system framework     

Selecting a Customization Strategy Under Competition: Mass Customization, Targeted Mass Customization, and Product Proliferation

Customization requires not only an implementation of proper manufacturing systems but also a proper strategy regarding when firms should offer customized products and what the nature of customization should be. This paper questions 1)whether customization is better than no customization, and, if so, 2) what kind of customization strategy firms should adopt under competition. We find that customization is not optimal when the cost of soliciting customer preference information is sufficiently high. When competing firms choose to customize, we show that firms target only certain customer segments with customized products. We also find that the optimal customization strategy may require firms to offer only a few discrete product varieties. Despite the concern that customization may initiate price wars because customization reduces product differentiation, we find that customization does not escalate the price competition, because aggressive price competition exacerbates cannibalization. Although customers within the product line of a firm are charged higher prices, we show that on average customers are better off when firms adopt customization. However, unless the customization is quite cheap, when firms choose to customize, we find that firms cannot generate more profits than when firms offer only a single product

Management of Product Architecture Modularity for Mass Customization: Modeling and Theoretical Considerations

This paper examines the management of product architecture modularity for mass customization. Product architecture modularity is concerned with system decomposition, the selection of components and how they are linked with each other without compromising system integrity. The goal of mass customization is to produce customized goods at low cost. It has enabled many companies to penetrate new markets and capture customers whose personal needs were not met by standard products and services. Mass customization is enabled through modular product architectures, from which a wide variety of products can be configured and assembled. In order to understand the implications of product architecture modularity for mass customization, the "modularization function" is explored by applying and simulating it to a hypothetical system. Based on this exercise and sources from the literature, a new model is introduced. Furthermore, theoretical and engineering management implications are also discussed     

Process Platform Planning for Variety Coordination From Design to Production in Mass Customization Manufacturing

The key challenge of implementing mass customization manufacturing lies in the variety dilemma exhibited by frequent design changes and recurrent process variations. A holistic view of variety handling gives rise to the importance of variety coordination from design to production. This paper proposes a concept of process platform for coordinating product and process variety. Fundamental issues of process platforms are studied regarding generic product and process structures, generic planning, and generic variety representation. Variety handlers and associated states are introduced to model the meta-structure inherent in variety coordination. A set of modeling formalisms are developed to provide a powerful syntactic model to support rigorous analysis and manipulation of process platforms, while facilitating the application of semantics to support process platform enactment and detailed observations from a number of perspectives involving customers, design and production. Also reported is a case study of mass customization manufacturing of vibration motors for mobile phone products. The managerial implications of process platform planning are further discussed     

Integrated Configuration of Platform Products and Supply Chains for Mass Customization: A Game-Theoretic Approach

This paper is concerned with optimizing the configuration of a set of platform products and the associated supply chain consisting of one manufacturer and multiple suppliers using a three-move dynamic game-theoretic approach. The variants in the product family share a common platform for developing/configuring variant modules which are substitutable in the sense that high-end module options can functionally replace low-end ones at higher prices. As the customer in the supply chain, the manufacturer takes its leading role by making the first move to give decisions on platform products development (PPD) and supplier selection. The concerned suppliers make the second move to optimize their decisions including price discounts and their ordering policies. The manufacturer finishes the game by taking the last move to make his ordering decisions. The ranges of the rational reactions for the players are derived from the analyses of their payoff models, and an enumerative algorithm is developed to find the subgame perfect equilibrium of the game through the technique of backward induction. The game model and the proposed solution procedure are illustrated through a series of simulation experiments and sensitivity analyses using a numerical example. The results have allowed us to draw some meaningful interpretations and useful managerial insights. The use of platform commonality and modularity has been found generally beneficial not only to the supply chain as a whole but also to individual players that are eventually configured into the game. Flexibility of the suppliers' capability is also found to affect the PPD decisions
