Using system dynamics for collaborative design: a case study

<p>Abstract</p> <p>Background</p> <p>In order to facilitate the collaborative design, system dynamics (SD) with a group modelling approach was used in the early stages of planning a new stroke unit. During six workshops a SD model was created in a multiprofessional group.</p> <p>Aim</p> <p>To explore to which extent and how the use of system dynamics contributed to the collaborative design process.</p> <p>Method</p> <p>A case study was conducted using several data sources.</p> <p>Results</p> <p>SD supported a collaborative design, by facilitating an explicit description of stroke care process, a dialogue and a joint understanding. The construction of the model obliged the group to conceptualise the stroke care and experimentation with the model gave the opportunity to reflect on care.</p> <p>Conclusion</p> <p>SD facilitated the collaborative design process and should be integrated in the early stages of the design process as a quality improvement tool.</p

The impact of competitive interactions on category penetration and purchase frequency of mature FMCG categories

Many fast moving consumer goods (FMCG) categories like laundry detergents, diapers or cereals are mature and rather stable, so the interest is high for manufacturers to make diagnostics on the category and their brand to find growth opportunities. Attempts to model mature category dynamics have mostly been based on probabilistic models. The most famous one is the “NBD-Dirichlet” model, which was first presented in 1984 and has subsequently triggered significant research in the area. The model has limitations as it assumes stable marketing and promotional activity and stable category dynamics. This paper uses a system dynamics model to relax some of these stability assumptions and explain how competitive dynamics impact the total category penetration, purchase frequency and volume size over time

Trading Off between Heijunka and Just-in-Sequence

The concept of heijunka-controlling the variability of the job arrival sequence to permit higher capacity utilization-plays an integral role in lean production theory. In situations where the customer defines the delivery sequence, however, scheduling production to maximize utilization becomes more challenging and requires a subsequent reordering. The cost of the extra work and space required by this reordering needs to be traded off against the value of the higher utilization. We present the results of a stylized simulation-based model of the two approaches inspired by a BMW engine plant

Flood Modelling and Visualizations of Floods Through 3D Open Data

Part 3: Water and HydrosphereInternational audienceThis paper is devoted to 3D modelling at the city level from data sources considered as open. The open data presented in this paper enable free usage, modifications, and sharing by anyone for any purpose. The main motivation was to verify feasibility of a 3D visualization of floods purely based on open technologies and data. The presented state-of-the-art analysis comprises the evaluation of available 3D open data sources, including formats, Web-based technologies, and software used for visualizations of 3D models. A pilot Web application visualizing floods was developed to verify the applicability of discovered data sources. 3D visualizations of terrain models, 3D buildings, flood areas, flood walls and other related information are available in a pilot application for a selected part of the city of Prague. The management of different types of input data, the design of interactive functionality including navigation aids, and actual limitations and opportunities for future development are discussed in detail at the end
