Hierarchical text classification plays an important role in many real-world applications, such as webpage topic classification, product categorization and user feedback classification. Usually a large number of training examples are needed to build an accurate hierarchical classification system. Active learning has been shown to reduce the training examples significantly, but it has not been ap...

This paper describes the development of a hierarchical planning and scheduling system for a multiple plant, multiple product, seasonal demand situation. In this hierarchical structure, optimal decisions at an aggregate level (planning) provide constraints for detailed decision making (scheduling). Four levels of decision making are used: first, products are assigned to plants (using mixed-integ...

Consumer-to-Consumer (C2C) E-commerce has been growing at a very high speed in recent years. Since identical or nearly-same kinds of products compete one another by relying on keyword search in C2C E-commerce, some sellers describe their products with spam keywords that are popular but are not related to their products. Though such products get more chances to be retrieved and selected by consu...

In this paper, a prototype system that focuses on affective design perspective for iterative product concept development is proposed and described. The prototype system, which emphasizes the solicitation of affective factors from both customers and designers, employs a sorting technique, i.e. picture sorts, for acquiring customer affect and a hierarchical structure for representing affective cr...

The target cascadingmethodology for optimal product development is extended to product families with predefined platforms. The single-product formulation is modified to accommodate the presence of shared systems, subsystems, and/or components and locally introduced targets. Hierarchical optimization problems associated with each product variant are combined to formulate the product family multi...

The software product-line approach (for software product families) is one of the success stories of software reuse. When applied, it can result in cost savings and increases in productivity. In addition, in safetycritical systems the approach has the potential for reuse of analysis and testing results, which can lead to a safer systems. Nevertheless, there are times when it seems like a product...
