Today’s market is becoming increasingly more competitive as companies strive to achieve success by reaching a large number of customers in a mass market while simultaneously treating them as individuals in a customized market. Many companies have begun to appreciate the benefits of using product platforms as they increase the customizability of their offered products, while reducing development costs and time to market. However, product variety is not customization; it is simply an attempt on the part of a company to meet the individual needs of their customers by flooding the market with many variations of the same product. With recent innovations in the field of information technology, web-based product development methodologies provide the capability for advanced customer involvement during the design process, which is a crucial aspect of differentiating customization from variety. Current approaches have provided web-based frameworks where users are offered a limited amount of control in the design process by assembling different configurations of given modules or by choosing a product already available in the company database. The focus in this paper is on advancements to a web-based framework where design parameters are collected from the user by means of a web-based browser interface, optimization is completed using the specified parameters, and a 3D visual representation is dynamically provided based on the results from the optimization. This proposed framework is illustrated using an example from ongoing research involving General Aviation Aircraft design.

For companies who must provide customized products on demand, it is important that the voice of the customer be addressed and incorporated early into the design process. Web-based design interfaces have emerged as useful tools to make customer voices interactive and provide a customer-friendly and cost-effective interface. The effectiveness of the interface can be greatly enhanced through implementation of a strategic customization process that can proactively react to customer requests. The design process represents a virtual product line that approaches the goal of providing infinite variety at minimal costs. The process provides a base for a true customization approach, which is different from the typical mass customization approach to provide ample but limited product variety a priori for a targeted market. In this paper, we describe the development of a prototypical custom product specification system and the underlying strategic design process that is based on a collection of product platforms. The development is illustrated using an example from on-going research with a company that produces customized valves for the power industry.

Product Realization

Product customization is a value-added activity that can significantly increase sales by increasing customer satisfaction. Many companies are using product platforms to increase product variety and customization while reducing development costs and time-to-market. While flooding the market with a variety of products may satisfy some customers by providing a substitute for customization, variety is not customization. This subtle, yet important, distinction between variety and customization motivates the need for investigating technologies to facilitate customer involvement during the product realization process, and our focus in this paper is on web-based platform customization strategies enabled by recent advances in information technology. Towards that end, we describe the development of an interactive web-based platform customization framework as an extension of product family design and present a prototype that has been created as part of on-going research with a company that produces customized refiner plates for pulp and paper processing. While the utility of the proposed web-based framework is demonstrated in the context of customizing a refiner plate design, the proposed framework is applicable to a variety of engineered products and enhances customer interaction during the product realization process while reducing design and manufacturing lead-time for custom orders.

Abstract In this paper we present the Product Variety Tradeoff Evaluation Method for assessment of alternative product platforms in product family design. The Product Variety Tradeoff Evaluation Method is an attention-directing tool for evaluating tradeoffs between commonality and individual product performance for product platform alternatives with differing levels of commonality. We apply the Product Variety Tradeoff Evaluation Method to a case study in transmission redesign for a family of cordless drills. The emphasis in this paper is placed on the method rather than on the results, per se.

Recent manufacturers have been utilizing product families to diversify and enhance the product performance by simultaneously designing multiple products under commonalization and standardization. Design information of product architecture and family is inevitably more complicated and numerous than that of a single product. Thus, more sophisticated computer-based support system is required for product architecture and family design. This paper proposes a knowledge model for a computer-based system to support reflective process of designing product architecture and product family. This research focuses on three problems which should be overcome when product family are modeled in the computer system; design repository without data redundancy and incorrectness, knowledge acquisition without forcing the additional effort on the designer, and integration of prescriptive models to support early stages of the design process. An ontology that is a foundation of a knowledge model is defined to resolve these problems. An example of designing an air conditioner product family is shown to demonstrate the capability of the system.

In an effort to increase customization for today’s highly competitive global markets, many companies are looking to product families to increase product variety and shorten product lead-times while reducing costs. The key to a successful product family is the common product platform around which the product family is derived. Building on our previous work in product family design, we introduce a product family penalty function (PFPF) in this paper to aid in the selection of common and scaling parameters for families of products derived from scalable product platforms. The implementation of the PFPF utilizes the powerful physical programming paradigm to formulate the problem in terms of physically meaningful parameters. To demonstrate the proposed approach, a family of electric motors is developed and compared against previous results. We find that the PFPF enables us to properly balance commonality and performance within the product family through the judicious selection of the common parameters that constitute the product platform and the scaling parameters used to instantiate the product family.

As companies are pressured to decrease product development costs concurrently with increasing product variety, the need to develop products based upon common components and platforms is growing. Determining why a platform worked, or alternatively why it did not, is an important step in the successful implementation of product families and product platforms in any industry. Unfortunately, published literature on platform identification and product family analysis using product dissection and reverse engineering methods is surprisingly sparse. This paper introduces two platform identification methodologies that use different combinations of tools that can be readily applied based on information obtained directly from product dissection. The first methodology uses only the Bills-of-Materials and Design Structure Matrices while the second utilizes function diagrams, Function-Component Matrices, Product-Vector Matrices, and Design Structure Matrices to perform a more in-depth analysis of the set of products. Both methodologies are used to identify the platform elements in a set of five single-use cameras available in the market. The proposed methodologies identify the film advance and shutter actuation platform elements of the cameras, which include seven distinct components. The results are discussed in detail along with limitations of these two methodologies.

Product Family Optimization

In order to improve the performance of automotive product platforms and product families while keeping high development efficiency, a product family optimization design method that combines shared variable decision-making and multidisciplinary design optimization (MDO) is proposed. First, the basic concepts related to product family design optimization were clarified. Then, the mathematical description and MDO model of the product family optimization problem were established, and the improved product family design process was given. Finally, for the chassis product family optimization problem of an automotive product platform, the effectiveness of the proposed optimization method, and design process were exemplified. The results show that the collaboratively optimized product family can effectively handle the coordination between multiple products and multiple targets, compared to Non-platform development, it can maximize the generalization rate of vehicle parts and components under the premise of ensuring key performance, and give full play to the advantages of product platforms.

Product platforms allow companies to compete in the global marketplace by facilitating product variety, by adding, removing, or substituting components and features across a product family, while reducing costs and lead times. In many cases, developing a common platform involves determining which components are in a product family, their connections, and their spatial layouts. The development of product configurations and layouts is a complex problem and involves both discrete and continuous mathematical processes. This paper presents algorithms and an implementation to address the problem of configuring products and component layouts. The algorithms will describe the processes used to generate the product configurations based on constraints on combinations and the layout of components within the products. The implementation presents software developed to present the algorithms for the configuration and layout processes.

In an effort to improve customization for today's highly competitive global marketplace, many companies are utilizing product families and platform-based product development to increase variety, shorten lead times, and reduce costs. The key to a successful product family is the product platform from which it is derived either by adding, removing, or substituting one or more modules to the platform or by scaling the platform in one or more dimensions to target specific market niches. This nascent field of engineering design has matured rapidly in the past decade, and this paper provides a comprehensive review of the flurry of research activity that has occurred during that time to facilitate product family design and platform-based product development for mass customization. Techniques for identifying platform leveraging strategies within a product family are reviewed along with metrics for assessing the effectiveness of product platforms and product families. Special emphasis is placed on optimization approaches and artificial intelligence techniques to assist in the process of product family design and platform-based product development. Web-based systems for product platform customization are also discussed. Examples from both industry and academia are presented throughout the paper to highlight the benefits of product families and product platforms. The paper concludes with a discussion of potential areas of research to help bridge the gap between planning and managing families of products and designing and manufacturing them.
