Abstract Hospitals are under continual pressure to improve turnaround times for surgical procedures and to find ways to release sterilized product without the need to wait for biological indicator (BI) results. Current procedures used in healthcare do not allow for release of sterilized products based on parameters because hospitals do not validate their sterilization processes. Once a sterilization process is validated for a particular product family, those loads may be released based upon evaluation of the sterilization parameters achieved in the cycle, i.e., parametric release. Typically, hospitals do not perform validation studies to demonstrate that a sterility assurance level (SAL) of 10−6 is being achieved in the sterilized product, relying instead on inactivation of BIs and/or chemical indicators (CIs) in each load. If a healthcare facility can demonstrate achievement of a SAL of 10−6 in a particular product family then it will be possible to release the products in that product family based on achievement of parameters without waiting for BI results. This does not mean that the healthcare facility can eliminate use of all BIs and CIs as part of the criteria for a comprehensive quality assurance program, but dependence on their results and the cost of their use may be greatly reduced. Validation provides another component in a quality assurance program to demonstrate that the highest SAL possible is being provided to patients while still providing the services required by today's healthcare facility.

Complex Relationships

Many industries are shifting from mass production to mass customization, which demands quick response to the needs of individual customers with high quality and low costs. The development of product families has received an increasing interest in recent years because, by sharing components across products, a family of products can be derived to cater variety while maintaining the economy of scale. Aiming at the computerization, and eventual automation, of product family design, this paper tackles the formal representation issue surrounding this economically important class of engineering design problem. Breaking free from conventional understanding of product families, which is limited as shared components, the paper defines a product family as a structured system to create variety of products with shared core product technologies. It not only involves the shared base product, but also encompasses customization modules, standard designs, and primary patterns of variety to generate custom designs. The paper introduces graph grammar formalisms to the modeling of such a product family. Based on Programmed Attributed Graph Grammars (PAGG), the graph language is developed to specify the design space of the product family. The process of customizing the base product through manipulating particular modules is modeled by rewriting the starting graph using a series of productions according to the control diagram. Configuration constraints are dealt with by defining application conditions for production rules. Control diagrams are constructed to capture complex relationships among modules and used to control the application sequence of production rules. A case study of power supplies is presented to demonstrate the potential of the graph grammar based modeling approach.

The Way

The competitiveness in today’s market forces many companies to rethink the way they design (and redesign) products. Instead of developing one product at a time, many manufacturing companies are developing families of products to provide enough variety for the marketplace while keeping costs relatively low. Although the benefits of commonality are widely known, many companies are still not taking full advantage of it when developing new products or redesigning existing ones. One reason is the lack of appropriate methods and useful metrics to assess a product family based on commonality and diversity. Although many component-based commonality metrics have been proposed in the literature, they do not (1) help resolve the tradeoff between commonality and diversity in a product family and (2) capture enough information to be completely useful during product family design and redesign. In this paper, we propose the Comprehensive Metric for Commonality (CMC) to evaluate the design of a product family on a 0–1 scale based on the components in each product, their size, geometry, material, manufacturing process, assembly, costs, and the allowed diversity in a family. To demonstrate the usefulness of this metric for product family benchmarking and redesign, the CMC is compared to six other component-based commonality indices. A CMC-based method is also proposed and applied to a family of staplers to (1) assess the level of commonality in the product family and (2) give recommendations for redesigning the product family.

Design Factors

Design Factors of product-family is one of the important elements to maintain and to improve customers’ loyalty to a band. Extraction of design factors of product family based on customer needs promotes relations between brands and customers while improves satisfaction to products of the consumers. In existing studies, methods of getting customer needs have always attracted close attention. But the links between customer needs and design factors have not been adequately studied. By using QFD (Quality Function Deployment) and increasing the number of cascaded transformation hierarchies of the House of Quality, the method of extracting design factors of product family is proposed in this paper.

System Layout

In their quest to manage the complexity of offering greater product variety, firms in many industries are considering platform-based development of product families. Key in this approach is the sharing of components, modules, and other assets across a family of products. Current research indicates that companies are often choosing physical elements of the product architecture (i.e., components, modules, building blocks) for building platform-based product families. Other sources for platform potential are widely neglected. We argue that for complex products and systems with hierarchic product architectures and considerable freedom in design, a new platform type, the system layout, offers important commonality potential. This layout platform standardizes the arrangement of subsystems within the product family. This paper is based on three industry case studies, where a product family based on a common layout could be defined. In combination with segment-specific variety restrictions, this results in an effective, efficient, and flexible positioning of a company's products. The employment of layout platforms leads to substantial complexity reduction, and is the basis for competitive advantage, as it imposes a dominant design on a product family, improves its configurability, and supports effective market segmentation.
