Foreword
This document is in accordance with GB/T 1.1-2020 Provisions of "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" drafted.
Introduction
The goal of digital shop floor reliability work is to ensure that it continues to produce qualified products that meet requirements. If the digital workshop is Failure to consider reliability issues in the design and engineering deployment process may result in unreliable operation of the digital workshop and production exceeding expectations. defective products, resulting in waste of resources; or system failures, increasing maintenance costs, and even causing production interruptions in severe cases, resulting in a large number of Economic losses. Therefore, in the process of design, engineering deployment and operation of the digital workshop, the reliability requirements of the digital workshop are clearly put forward.
Reliability work items are specified, and technologies such as reliability design, testing, and management are used comprehensively to carry out relevant reliability work to ensure the reliability of reliability. Reliable operation of the digitizing workshop.
The digital workshop is the core component of intelligent manufacturing, which improves the overall operational reliability of the digital workshop and guides the functions of the digital workshop.
Energy security construction and information security construction are in urgent need of relevant standards for regulation and guidance. Therefore, according to the national intelligent manufacturing standard system construction guidelines South requirements, general requirements for digital workshop reliability, digital workshop functional safety requirements and digital workshop information security requirements and other basic commonalities Standards are part of the intelligent manufacturing standard system framework, as shown in Figure 1.
1 Scope
This document specifies general reliability requirements for digital workshops, including general reliability requirements, reliability work item requirements, reliability Design requirements, reliability management requirements and reliability verification requirements, etc. This document applies to new or retrofitted digital workshops.
2 Normative references
The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document.
GB/T 2422 Guidelines for Compilation of Test Methods for Environmental Testing Terms and Definitions GB/T 37393-2019 General technical requirements for digital workshops
3 Terms and Definitions GB/T 2422 and the following
terms and definitions apply to this document.
3.1 Software reliability
reliability The ability of software to perform required functions under given conditions and within a given time interval.
3.2 Overall equipment
efficiency equipment It is used to express the ratio of the actual production capacity of the equipment to the theoretical capacity. OEE=Equipment Availability Rate (AF)×Operation Performance Rate (PF)×Quality Qualification Rate (QF)
3.3 Failure rate
rate Reliability parameter [lambda(t)] of an entity (single component or system)
, that is, lambda(t)dt indicates that the entity has not lost or lost between [0, t]
The probability of failure within [t, t dt] in case of failure. Note 1.
Mathematically, lambda(t) is the conditional probability of failure per unit time [t, t dt], which is closely related to the reliability function (that is, the probability that failure does not occur within 0~t).
Tangent correlation can be expressed by the formula. R(t)=exp -integral lambda(tau)dtau. Conversely, it can be represented by the reliability function. lambda(t) = -dR (t) R(t) Note 2.
The failure rate and its uncertainty can be estimated by traditional statistics from field feedback data, and a short period of time during the service life (ie, after aging to before scrapping).
The failure rate of a single term is almost equal to a constant, lambda(t) = lambda. Note 3.
Average value of lambda(t) in the given interval [0,T], lambdaavg(T)=integral lambda(tau)dtau/T, not the failure rate, because the average value cannot be used to calculate Note 1 R(t) in, but can be interpreted as the average frequency of failures during this period (i.e. PFH, GB/T Appendix B in 20438.6-2017). Note 4.
The failure rate of the concatenated terms is the sum of the failure rates of each term. [Source: GB/T 20438.4-2017, 3.6.16, with modifications]
