Producers. The producers of databases are sometimes called database publishers because they make pubHc their databases. Some producers pubhsh hardcopy counterparts to databases and so are pubHshers in the traditional sense others pubHsh data only in electronic form. Database producers are responsible both for the deterrnination of content and for database production. Most producers offer their databases for lease or Hcense to private organisations or database vendors. Vendors offer database search services to the marketplace on a fee basis. An increasing number of producer/vendors such as Mead Data Central, U.S. National Library of Medicine, and DRI/McGraw-HiU. (formerly Data Resources), offer search services (batch or online) from their own databases as well as from the databases of other products.

Know what resources are available and how to access them. Human resources, data resources, and technical expertise may be available in both companies. Someone in a consultant s organization may have seen a similar situation that can provide insight. Networking is essential. 

Chapter 4—Data Bases, Sources, and Studies Summarizes and characterizes several generic data resources available to risk analysts and process engineers in the CPI. It includes a discussion of the resource search and selection process and the presentation format for the information on resources. 

Chapter 5—CCPS Generic Failure Rate Data Base Contains tables of generic process equipment reliability data that are structured by the CCPS Taxonomy. The data are extracted from data resources in Chapter 4. The chapter includes a discussion of the selection, treatment, and presentation of the data in the Tables. 

Appendix C—Matrix of Data Elements in Each Data Resource Presents the user with a more detailed summary of the data elements available from each data resource in Chapter 4. 

Appendix D—Unreviewed Data Bases, Data Sources, and Studies Provides a list of data resources that were uncovered too late for review.

Seetion 4.1 deseribes how data resourees were ehosen for inelusion in this book. Section 4.2 describes the format used to present the information on the data resources, and Sections 4.3 through 4.8 present these data resources. Eaeh resouree section is preceded by an index of the resources presented in the section. 

The selection of data resources was a three-step proeess ... 

Titles of potential resourees were obtained by eonducting a literature search and an industry survey. Simultaneous literature searches were condueted by CCPS and SAIC. CCPS eoneentrated on obtaining CPI data resources while SAIC used a literature search conducted for the nuclear power reliability eommunity. These literature searches used in-house eompany, engineering, and public libraries and recommendations from members of the user eommunity. At the same time, a questionnaire was sent to professionals who eonduct CPQRAs. The survey requested information on the data resourees used by the companies and whether they had plant-speeific data that could be used by CCPS. Members of the CCPS Equipment Reliability Data Subcommittee were also asked to eompile lists of data resources with which they were familiar and which they had used for reliability or risk analyses. As a result, an extensive but not necessarily eomplete list of data resource titles was assembled. Any resources uncovered after the publisher s eutoff date and not reviewed have been included in Appendix D. 

The effort to collect CPI and general reliability data resources is considered by CCPS to be an ongoing projeet. Users of this book are encouraged to assist in this process by recommending additional resources to CCPS that ean be used for subsequent editions of this book. 

The selected data resources were sorted into the six categories, each presented in a section of this chapter. Resources are numbered consecutively within each category. The sections and categories are ... 

The contents of these data resource summaries have been verified by calling the contacts and confirming ordering addresses. Information is current as of August 1988. 

This section describes the format used to characterize the information in the data resources presented in Sections 4.3 through 4.8. The following data elements are used to present information in the resources summaries ... 

Title The name of the data resource as shown on the data source, as described in literature explaining data base services, or as conventionally cited when referencing a CPQRA or PRA. 

To help the reader select the appropriate data resource, an index precedes Sections 4.3 through 4.8. The index provides the source number within the section and the following set of data elements for each source title, industry, number and type of records, and data boundary. Appendix C contains additional information about the data elements presented in each data resource. It can also be used to help identify the resources which may provide data for a CPQRA. A discussion of the Appendix C Matrix and an explanation of data elements indexed is presented. After examining Appendix C and the pattern of data elements contained in the data resources, it is evident that equipment reliability data have been published in a variety of formats, often without any apparent effort to conform to a recognized standard for data specification. The CCPS Taxonomy and the raw data collection requirements in Chapter 6 present the basis for reliability data specification in future literature. 

Data Resource 4.3-4 Fluor Daniel Data Base... 

SAIC provided much of the data used in this book from its proprietary files of previously analyzed and selected information. Since these data were primarily from the nuclear power industry, a literature search and industry survey described in Chapter 4 were conducted to locate other sources of data specific to the process equipment types in the CCPS Taxonomy. Candidate data resources identified through this effort were reviewed, and the appropriate ones were selected. Applicable failure rate data were extracted from them for the CCPS Generic Failure Rate Data Base. The resources that provided failure information are listed in Table 5.1 with data reference numbers used in the data tables to show where the data originated. 

Data Reference No. Data Resource Title Chapter 4 Resource No. 

Comments—text field of 100 characters allowing notes on the data or the data resource. 

The data points from SAIC s data base were already stored in CARP files. Data extracted from the CPI data resources were also entered into CARP files for storage and organization of the data points by their relevant taxonomy levels. 

Equipment description Defines the equipment type that the data applies to data resource equipment descriptions were used to match data to the descriptions at the taxonomy levels. 

Data reference number Refers to Table 5.1, which cites the data resources used to provide the failure rates presented in the data cell.
