CDD CERN Drawings Directory User's manual: Version 1.1

CDD (CERN Drawings Directory) is a multi-platform utility which manages engineering drawings made in any division at CERN. The aim of CDD is not to store the graphical drawing itself, but to store a reference with some information related to the drawing. Access to this data is provided via a graphical user interface which is based upon ORACLE Forms and via WWW. Drawings following different numbering systems and different management rules can be handled by CDD. The only condition is that those particular functionalities are well defined. Several drawing systems have been identified in CERN and therefore considered when designing the application. The current version of CDD focuses on systems EST, LEP, ST-IE, SPS, ST-CE and the experiments ALICE, ATLAS, CMS and LHCb. Other CERN systems could be easily integrated upon demand

Integrated Project Support Study Group : findings

The challenges of the LHC project have lead CERN to produce a comprehensive set of project management tools covering engineering data management, project scheduling and costing, event management and document management. Each of these tools represents a significant and world-recognised advance in their respective domains. Reviewing the offering on the eve of LHC commissioning one can identify three major challenges: 1. How to integrate the tools to provide a uniform and integrated full-product lifecycle solution 2. How to evolve the functionality in certain areas to address weaknesses identified with our experience in constructing the LHC and integrate emerging industry best practices 3. How to coherently package the offering not just for future projects in CERN, but moreover in the context of providing a centre of excellence for worldwide collaboration in future HEP projects

The CEDAR Project

The LHC project at CERN requires both the handling of a huge amount of engineering information and the control of the coherence of this information as the design work evolves on the machine and the experiments. A commercial Engineering Data Management System, (EDMS), is being implemented to manage data for the design, construction, installation and maintenance of both the accelerator and the experiments. This CERN-wide project is called CEDAR The World Wide Web is used to make the information accessible at CERN and in the external collaborating laboratories around the world. In this paper we describe the objectives of the CEDAR project, the different subprojects in the machine and the experiments as well as the first results of the implementation work

CDD CERN Drawing Directory - Version 1.2: User's Manual

This manual describes the CERN Drawing Directory application (CDD). It is both an introductory guide for the new user and a reference manual for the experienced user. There is another manual available for CDD administrators, the present manual is oriented to standard users of the application

ADaMS 3: An Enhanced Access Control System for CERN

ADaMS is CERN's Access Distribution and Management System. It evaluates access authorizations to more than 400 zones and for more than 35k persons. Although accesses are granted based on a combination of training courses followed, administrative authorizations and the radio-protection situation of an individual, the policies and technicalities are constantly evolving along with the laboratory's activities; the current version of ADaMS is based on a 7 year old design, and is starting to show its limits. A new version of ADaMS (3) will allow improved coordination with CERN's scheduling and planning tools (used heavily during technical shutdowns, for instance), will allow CERN's training catalog to change without impacting access management and will simplify and reduce the administrative workload of granting access. The new version will provide enhanced self-services to end users by focusing on access points (the physical barriers) instead of safety zones. ADaMS 3 will be able to cope better with changing and new requirements, as well as the multiplication of access points. The project requires the cooperation of a dozen services at CERN, and should take 18 months to develop
