Hazard Rate01:11

Hazard Rate

199
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...

The Availability Heuristic01:08

The Availability Heuristic

6.6K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Design Consideration01:22

Design Consideration

339
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

Survey Safety01:28

Survey Safety

189
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Types of Errors: Detection and Minimization01:12

Types of Errors: Detection and Minimization

3.4K
Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

Machines: Problem Solving II

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Background:

  • Human activities are a significant source of errors in industrial operations.
  • Human Reliability Analysis (HRA) is crucial for identifying and quantifying these errors.
  • Liquefied Petroleum Gas (LPG) operations require rigorous safety protocols due to inherent risks.

  • Systematic Human Error Reduction and Prediction Approach (SHERPA) for error identification and categorization.
  • Fuzzy Failure Mode and Effect Analysis (F-FMEA) for risk quantification.
  • VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) for risk prioritization.

Main Results:

  • The methodology effectively identifies and categorizes potential human errors in LPG unloading.
  • F-FMEA and VIKOR successfully quantify and rank the risks associated with these errors.
  • The approach provides a clear understanding of risk severity at various operational levels.

Conclusions:

  • The presented methodology offers a robust framework for managing human reliability in LPG operations.
