A manufactured product usually has a great amount of design knowledge and other product information associated with it in CAD drawings and other technical documentation. Today, such product information mainly enables preventive maintenance of products. By collecting usage, performance and maintenance information about the product, it could be possible to perform more predictive maintenance. The...

Software product line (SPL) is a set of software systems that share a common set of features satisfying the specific needs of a particular market segment. A feature represents an increment in functionality relevant to some stakeholders. SPLs commonly use a feature model to capture and document common and varying features. The key challenge of using feature models is to derive a product configur...

Product names with a temporal cue in a product review often refer to several product instances purchased at different times. Previous approaches to product entity recognition and temporal information analysis do not take into account such temporal cues and thus fail to distinguish different product instances. We propose to formulate the resolution of such product names as a classification probl...

Development and management of software product families is an emerging and important area of software engineering, whereas product configuration of traditional, i.e., mechanical and electronic, product families has a slightly longer history as a specific area of research and business. This paper describes work in progress on the management of configurable software product families. Solutions to...

Many enterprises have been devoting a significant portion of their budget to new product development (NPD) in order to distinguish their products from those of their competitors, and to make them better fit the needs and wants of customers. Hence, businesses should develop products that fulfill the customer demands, since this will increase the enterprise’s competitiveness and it is an essentia...

The notion of strongly Lie zero-product preserving maps on normed algebras as a generalization of Lie zero-product preserving maps are dened. We give a necessary and sufficient condition from which a linear map between normed algebras to be strongly Lie zero-product preserving. Also some hereditary properties of strongly Lie zero-product preserving maps are presented. Finally the second dual of...

This paper provides a model that uses preference heterogeneity to rationalize the crosssectional and intertemporal variation in a firm’s product proliferation strategies. Product-line dynamics arise from shocks to preference heterogeneity. For example, in the potato chip category I study, consumer concerns over fat levels in foods created two desirable alternatives (low fat and zero fat) for ea...
