The paper presents an Augmented Reality (AR) application for a design review within the automotive development. Objective of the work was to identify use cases and functions that are essential for an AR-based design review. For this purpose the use cases and a set of functions are presented, which add value to the design review process and enhance the existing methods. The uses cases are the design review of virtual car in a real environment and the preparation of real prototypes. The functions are a virtual construction kit, realistic illumination as well as multi-viewer support. The functions have been tested; some user tests have been carried out. The results show AR enhances the design review process using realizable and established techniques. The paper summarizes the work in the field, which has been accomplished between 2003 and 2008. © Organizing Committee of TMCE 2010 Symposium. Source

Complexity management and management of assortment variety in particular is the subject matter of many strategic decisions in consumer goods industries. As the assortment of a company evolves continuously by introducing new or discontinuing existing products, the most important question is what effects on the configuration of the production and distribution network and related costs can be expected if the assortment is changed in a particular way?. This work presents the concept for a decision support system (DSS) that evaluates the most relevant assortment dependent cost positions for a production and distribution network, focusing on the areas of inventory management and production execution. An overview of the prototype DSS implementation Complana and its sample application to the cloths' supply chain of an international household product manufacturer is given. © 2010 Springer-Verlag.

In the past decade, logistics in the context of humanitarian operations has more and more moved into the focus of logistics practitioners and academics. While humanitarian organisations have realised that a major part of disaster relief spending can be attributed to logistics and supply chain management activities associated with humanitarian operations, researchers have found that the area of logistics in the context of humanitarian operations gives rise to a number of unique and interesting challenges. This paper is meant as an introduction to the track Humanitarian Logistics at the 8th International Heinz Nixdorf Symposium. A recent natural disaster helps to elaborate the domain humanitarian operations. A number of important definitions are presented. Moreover, some of the specific characteristics and challenges of logistics in the context of humanitarian operations are described. © 2010 Springer-Verlag. Source

A distributed satellite system is composed of several small satellites working collaboratively or symbiotically together on a satellite mission. In such a system, fault detection can be executed in a similar way the distributed and specialized cells of the biological immune system find and counteract sicknesses. This paper proposes the use of an agent-based artificial immune system model for the detection of faults. The method takes into account the reduced memory and computational resources that small satellites have, applying control of population of agents through death and reproduction, and dimension reduction of the signatures that identify the agents. Simulations of the dynamics of the population of agents, of a model adjusted to a system with several satellites, shows emergent properties for encountering faults and counteracting them correspondingly.

This chapter presents an approach for the automatic combination of different models in order to build-up a virtual prototype automatically. Semantic Web techniques are used for that purpose; aim of the work has been to verify if Semantic Web techniques are suitable for that purpose. Therefore, the models that need to be combined become semantically annotated. The items of 3D models and multibody systems are presented, which need to be annotated in order to facilitate an automatic combination of these two types of models. To combine them the relations between both models need to be identified. A reasoning mechanism is presented that indentifies these relations. The automatic combination of models simplifies the build-up of virtual prototypes. In future, it facilitates complex virtual prototypes that consist of multiple models. Due to the addition of a semantic to the models, the virtual prototype is denoted as Semantic Virtual Prototype. © Springer-Verlag Berlin Heidelberg 2011. Source
