The pressure to reduce product development time has increased due to rapidly changing technology and customer's needs. Therefore, a shortened product development time has become a critical issue for many enterprises. Being first to market is a major strategy for establishing product identity and capturing market share. Axiomatic design can be used to structure the design processes and reduce th...

Software product line engineering allows large software systems to be developed and adapted for varying customer needs. The products of a software product line can be described by means of a hierarchical variability model specifying the commonalities and variabilities between the artifacts of the individual products. The number of products generated by a hierarchical model is exponential in its...

Document-level sentiment classification aims to predict user’s overall sentiment in a document about a product. However, most of existing methods only focus on local text information and ignore the global user preference and product characteristics. Even though some works take such information into account, they usually suffer from high model complexity and only consider wordlevel preference ra...

In this paper, we describe an ontology for a hierarchically organized production control system in semiconductor manufacturing. The semiconductor manufacturing domain is characterized by reentrant product flows, sequence dependent setup-times, prescribed due-dates, a diverse product mix, a mix of different process types including batch processes and preventive maintenance issues because of comp...

Holistic methods covering the development process as a whole – e.g. systems engineering – have established themselves in product design. However, technical product optimization, representing improvements in efficiency and/or minimization of loss, usually applies to single components of a system. A holistic approach is being defined based on a hierarchical point of view of systems engineering. T...

Now there is tremendous interest in data warehousing and OLAP applications. OLAP applications typically view data as having multiple logical dimensions (e.g., product, location) with natural hierarchies de ned on each dimension, and analyze the behavior of various measure attributes (e.g., sales, volume) in terms of the dimensions. OLAP queries typically involve hierarchical selections on some ...

A key challenge in software product line engineering is to represent solution space variability in an economic, yet easily understandable fashion. We introduce the notion of hierarchical variability models to describe families of products in a manner that facilitates their modular design and analysis. In this model, a family is represented by a common set of artifacts and a set of variation poi...

Nowadays the new product and its importance are consideredas an essential strategy for staying in business. Though the hi-techindustry has focused on value innovation and improving the qualityof the new product development (NPD) process to drive new productperformance, new product success has not changed dramaticallyover the years. This study presents a novel approach based on structuralequatio...

Software product line engineering is a very common method for designingcomplex software systems. Feature modeling is the most common approach tospecify product lines. The main part of a feature model is a special tree offeatures called a feature diagram. Cardinality-based feature diagrams providethe most expressive tool among the current feature diagram languages. Themost co...
