10、1636:2016IEEE Std 1636-2009 IEEE Standard for Software Interface for Maintenance Information Collection and Analysis (SIMICA) 3 Copyright 2013 IEEE. All rights reserved. 1.2 Scope This standard is an implementation-independent specification for a software interface to information systems containing
11、data pertinent to the diagnosis and maintenance of complex systems consisting of hardware, software, or any combination thereof. These interfaces will support service definitions for creating application programming interfaces (API) for the access, exchange, and analysis of historical diagnostic and
12、 maintenance information. The standard will use the information models of IEEE Std 1232 as a foundation. 1.3 Purpose The purpose of this standard is to specify a software interface for access, exchange, and analysis of product diagnostic and maintenance information. This will address the pervasive n
13、eed of organizations to assess the effectiveness of diagnostics for complex systems throughout the product life cycle. The use of formal information models will facilitate exchanging historical maintenance information between information systems and analysis tools. The models will facilitate creatin
14、g open system software architectures for maturing system diagnostics. 1.4 Application This standard should be applied in the development of software applications that access or provide information relevant to the diagnosis and maintenance of systems.

Backgrounds 4.1 Diagnostic maturation The process of maturing a system diagnostic design begins in the systems conceptual de
34、sign phase and continues throughout the system life cycle. Generally diagnostic design are demonstrated prior to delivery of the first unit to meet the diagnostic and health management requirements that have been levied. However, once a system is fielded and used in an operational environment, unexp
35、ected and unplanned system level design interactions, operational and environmental stresses, and other influences tend to reveal deficiencies in the diagnostic capabilities. When such deficiencies result in a weapon system readiness or cost of ownership problem, remedial actions must be taken: The
36、performance issue must be clearly characterized in terms of scope, impact, and ownership. Root cause analysis must be performed to identify potential courses of actions, including adjustments, improvements, or refinements to support and operational elements. The resulting courses of action must be d
37、eployed in a manner that is both economically feasible and consistent with product functional and operational requirements. The diagnostic maturation process requires access to design, maintenance, and logistics support information sources. Aggregation of system failure and performance data from dis
38、parate information sources is a multidisciplinary issue, i.e., relevant data exists within the purview of engineering, product support, and other organizations. Each of these organizations is also multifaceted in nature. Engineering organizations, for example, are composed of sub-disciplines such as
39、 design, reliability and maintainability, etc. Compounding the problem is the fact that the data of interest resides in multiple systems each with different owners where it does existand it should be recognized that some data that is desirable to have might not be captured in data systems at all. Th
40、e problem can be reduced by operating with a single, unified conceptual view of the data to be extracted from multiple sources. Therefore, the challenge is how to extract the information of interestheterogeneous system failure and performance datafrom the disparate data systems where it resides. The
41、 idea is to identify the information of interestand in fact, to create an information model so that it is clear what that data is and what it really means in the context of system usage and analysisthen determine the process for obtaining that information. Once data requirements and availability are
42、 determined, one can then begin trying to solve the puzzle of how to integrate the heterogeneous information to be obtained, i.e., how to relate the vital information from any one system to the others that capture related information but using disparate data formats and semantics. Data collection is
43、 a prerequisite for the maturation process, and the product data that is typically required for maturation analysis is generally stored in heterogeneous data systems. This standard will facilitate improved access, retrieval, and integration of the requisite information from these data systems. The i
44、ntent of the SIMICA family of specifications is to provide an implementation-independent specification for a software interface to information systems containing data pertinent to the diagnosis and maintenance of complex systems consisting of hardware, software, or any combination thereof. These int
45、erfaces will support the creation of service definitions for application programming interfaces (API) for the access, exchange, and analysis of historical diagnostic and maintenance information.
