What is it?

Reliability Problem Solving addresses the use of an appropriately tailored suite of reliability engineering activities, tools, methods, procedures, etc., to cost-effectively identify and correct design/process reliability problems.

What’s the payoff?

Reliability problem solving activities actively promote reliability growth by identifying and eliminating/mitigating failure modes/ mechanisms in designs and processes. Successfully minimizing the effects of failure can result in lower risk in meeting reliability requirements, an increase in new/repeat business and reduced warranty and maintenance costs.

How can we help?

  • Ensure that your reliability data is effectively collected, analyzed and used for informed decision making: Failure Reporting, Analysis and corrective Action System (FRACAS)
  • Perform analyses of your designs/processes and make recommendations to help you better understand the causes of failure: Failure Modes, Effects and Criticality Analysis (FMECA), Fault Tree Analysis (FTA), Worst Case Analysis (WCA), Physics-of-Failure (PoF) Analysis
  • Perform analyses of your test programs and make recommendations to ensure a cost-effective, value-added reliability test strategy: Design of Experiments (DOE), Accelerated Life Test (ALT), Reliability Growth Test (RGT), Reliability Screening

  • Achieving System Reliability Growth Through Robust Design and TestThis book offers new definitions of how failures can be characterized, and how those new definitions can be used to develop metrics that will quantify how effective a Design for Reliability (DFR) process is in (1) identifying failure modes and (2) mitigating their root failure causes.
  • DeratingThe practice of limiting electrical, thermal and mechanical stresses on parts to levels below their specified ratings is called derating. MIL-STD-721C offers the following definitions of derating: Using an item in such a way that applied stresses are below rated values The lowering of the rating of an item in one stress field to allow…  Read More
  • Mission Reliability and Logistics Reliability: A Design ParadoxThe goal of improving system reliability often presents a design paradox; “mission” reliability cannot be increased without simultaneously decreasing “logistics” reliability. When faced with the challenge of a system that has inadequate reliability to meet specification requirements, hardware redundancy is often implemented, leading to
  • Using Accelerated Life Testing to Assess Warranty RiskDuring a recent project, a question arose about the feasibility of providing a ten year warranty for a new system. The system consisted of a proven electronic assembly and 40 newly designed hybrid electronic modules. Warranty costs could be significant if reliability risks were not fully understood. The company producing the system
