Integration of Standardized and Non-Standardized Product Data

Abstract: Smart products adapt to environments, process contexts, users and other products. Standardized product data such as BMECat, eCl@ss, and EPC global formats are designed to support the exploitation of product data and therefore contribute to more efficient supply chains. Non-standardized product data mainly target soft benefits which targets the exploration of product dat

The Open Assembly Model for the Exchange of Assembly and Tolerance Information: Overview and Example

In early design phases an effective information exchange among CAD (Computer Aided Design) tools depends on a standardized representation for the product data in all PLM (Product Lifecycle Management) tools. The NIST Core Product Model (CPM) and its extension are proposed to provide the required base-level product model that is open, non-proprietary, generic, extensible, independent of any one product development process and capable of capturing the full engineering context commonly shared in product development [1]. The Open Assembly Model (OAM) Model extends CPM to provide a standard representation and exchange protocol for assembly. The assembly information model emphasizes the nature and information requirements for part features and assembly relationships. The model includes both assembly as a concept and assembly as a data structure. For the latter it uses the model data structures of ISO 10303, informally known as the Standard for the Exchange of Product model data (STEP)[2]. The objective of the paper is to show how the OAM can be used to realize seamless integration of product information, with an emphasis on assembly, throughout all phases of a product design. A gearbox design example is used to illustrate the process

Proposta de organização e visualização de grande quantidade de imagens orbitais através de web services.

The organization of satellite imagery seeks to facilitate the presentation and manipulation of spatial information in projects of Land Management's Strategic area from Embrapa Satellite Monitoring, enabling integration between mapped data and interoperability of image data and mapped regions. As a way to standardize this organization, we followed the recommendations of national and international bodies that deal with the standardization of geographic metadata, specifically satellite images. To view this integration, a webmapping interface was created. A webmapping must be prepared to meet the needs of relationship between user and product. In this paper we propose a standardized structure for storage and maintenance of images obtained by satellite sensors aiming its availability on the web through web map services, examples of interoperability. The non-interoperability prevents sharing of information and computing resources. The visualization of web map services takes place through a webmapping that benefits from the organization structure of satellite images proposed in this paper. The hierarchical organization proposed research assistance of satellite images. As they are entered into the database, now new images will be organized in a logical structure, without affecting the search for listings older images. The webmapping allows a direct link between the metadata and geospatial data visualization. Combining web services based on Geographic Information Systems (GIS) in conjunction with the Flex technology allows the creation of Rich Internet Applications (RIA) giving the user more possibilities of interaction via the Web

The Dynamics of Transformation in the Development of Digital Services

Service providers are increasingly depending and using digital infrastructure and tools provided by digital platforms to transform their services and develop digital ones that meet the needs of heterogeneous end users. However, while there is an emerging literature of developing digital services, little is known about the dynamics of transformation. Using multiple cases of firms that develop digital services, the digital service taxonomy was synthesized to understand the dynamics of transformation in developing digital services. This study identifies five main dynamics: the services experience, the service process, the service capabilities, the service environment and the service delivery.  Each of those dynamics and their associated factors is explored under the objectives of business, interaction and technology. This enables us to extend the existing literature on digital service development in particular and contributes to the research of digital innovation in general

Does IT standardization help to boost cost and profit efficiency? Empirical evidence from German savings banks

This paper investigates the impact of IT standardization on bank performance based on a panel of 457 German savings banks over the period from 1996 to 2006. We measure IT standardization as the fraction of IT expenses for centralized services over banks' total IT expenses. Bank efficiency, in turn, is measured by traditional accounting performance indicators as well as by cost and profit efficiencies that are estimated by a stochastic frontier approach. Our results suggest that IT standardization is conducive to cost efficiency. The relation is positive and robust for small and medium-sized banks but vanishes for very large banks. Furthermore, our study confirms the often cited computer paradox by showing that total IT expenditures negatively impact cost efficiency and have no influence on bank profits. To the best of our knowledge, this paper is first to empirically explore whether IT standardization enhances efficiency by employing genuine data of banks' IT expenditures.

Scaling limits for the Lego discrepancy

For the Lego discrepancy with M bins, which is equivalent with a chi^2-statistic with M bins, we present a procedure to calculate the moment generating function of the probability distribution perturbatively if M and N, the number of uniformly and randomly distributed data points, become large. Furthermore, we present a phase diagram for various limits of the probability distribution in terms of the standardized variable if M and N become infinite.Comment: 16 page
