We consider the role of ‘workplace studies’ in design and specifically, what it means to use ethnography to ‘inform’ design. We suggest that there is a need for a foundational change in the configuration of the practical relationship between ethnography and design if the approach is to be of lasting utility: from the traditional product-oriented configuration where ethnography attempts to infor...

Abstract Driven by an increasing demand for individualized products and shorter product life-cycles, companies continuously extend their portfolio. Simultaneously, expand into new markets to reach customers exploit varying location factors reduce costs. Global production networks (GPNs) have be adapted constantly react circumstances changes in the of products. To remain competitive, allocation ...

In this paper a framework for engineering supervisory controllers product lines with dynamic feature configuration is proposed. The variability in valid configurations described by model. Behavior of system components achieved using (extended) finite automata and both behavioral constraints are expressed means requirements as common control theory. Supervisory controller synthesis applied to co...

Abstract The product functional configuration (PFC) is typically used by firms to satisfy the individual requirements of customers and realized based on market analysis. This study aims help analyze functions realize configurations using patent data. first proposes a patent-data-driven PFC method hypergraph network. It then constructs weighted network model optimize combination function quantit...

Trajectory tracking and configuration stabilization for the vertical takeoff and landing (VTOL) aircraft has been so far considered in the literature only in the presence of a slight (or zero) input coupling (i.e., for a small ). In this note, our main contribution is to address global configuration stabilization for the VTOL aircraft with a strong input coupling using a smooth static state fee...
