Criticality Analysis (FMECA)
Failure Modes, Effects, & Criticality Analysis (FMECA)
Failure Modes and Effects Analysis (FMEA) is a bottom-up, inductive analytical method, which may be performed at either the functional or piece-part level. FMECA extends FMEA by including a criticality analysis, which is used to chart the probability of failure modes against the severity of their consequences.
A FMECA report consists of the system description, assumptions, conclusions and recommendations, corrective actions to be tracked, and the FMECA matrix, which may be a spreadsheet, worksheet, or database. The results highlight failure modes with a relatively high probability and severity of consequences – allowing remedial effort to be directed where it will produce the greatest value.
FMECA tends to be preferred over FMEA in space and North Atlantic Treaty Organization (NATO) military applications, while various forms of FMEA dominate in other industries. DTB’s logistics professionals can support both types of analysis.
for the Military
Provisioning Data for the Military
For military programs, DTB produces provisioning data as specified in the LMI data selection matrix. We generate all required provisioning technical data, including Provisioning Parts List (PPL), Long Lead Items List (LLIL), and Interim Support Items List (ISIL), which is delivered electronically to procuring agencies.
Our parts specialists are experts at meeting Uniform DoD Requirements for Provisioning Technical Documentation (MIL-STD-1552A), DoD Requirements for a Logistic Support Analysis Record (MIL-STD-1388-2A and -2B), and Performance Specification: Logistics Management Information (MIL-PRF-49506).
We create logistics databases according to military specifications – while populating the fields defined by Government Contract Deliverable Requirements Lists (CDRLs).
Level of Repair Analysis (LORA)
The reason to perform LORA is to establish the most cost-effective repair level or discard alternative in order to perform maintenance actions. Maintenance planning relies on LORA as a function of the acquisition process. LORA is used by the Department of Defense (DoD) as an analytical methodology in order to determine when an item will need to be replaced, repaired, or discarded based on cost considerations and operational readiness requirements.
LORA optimizes the support system in terms of Life Cycle Costs (LCCs), readiness objectives, design for discard, maintenance task distribution, support equipment and Automatic Test Equipment (ATE), and manpower and personnel requirements.
Complex engineering systems contain thousands of assemblies, sub-assemblies, and components, each organized into several levels of indenture with a number of possible repair decisions. LORA seeks to determine an optimal provision of repair and maintenance facilities in order to minimize overall system LCCs.
It is important to review all of the details in order to provide clients with actionable information. DTB addresses this aspect so that you can focus on the other areas of your business.
