AeroLogLabTOOL® Semantic Rules
To avoid or minimize misunderstandings
A set of processes, sub-processes and tasks.
A routine.
A set of rules used to make a calculation or solve a problem.
Percentage of time a system is capable of performing an assigned mission.
See Metrics Menu

Miscellaneous
An independent variable or predictor variable, a feature is an observable quantity, recorded and used by a prediction model.
You can engineer features by combining them or adding new information to them.
- Some action programmed in a routine service.
- A job may be scheduled or reactive.
- A Job may be related to a IPSP Task.
Scheduled: have breakfast every day at 07:15
Reactive: brush the teeth as soon as possible
- Line Replaceable Unit
- Something designed to be replaced quickly at an operating location.
Further the LRU is sent to the local workshop or to the contractor for repairs.
The probability that a system will
perform without failure over a specific
interval.
The Reliability of the subsystem A is 0.97 for 500 hours.

A mathematical representation of a real world process.
A predictive model forecasts a future outcome based on past behaviors.
Parts substitution for more performing ones.
Avionics model exchange.
A methodology to be used for developing scheduled maintenance tasks and intervals, to implement RCM philosophy.
The basic goal of MSG-3 is to identify maintenance tasks which are both effective and efficient in enabling a new aircraft to be designed and operated in a manner which achieves a satisfactory level of safety and reliability throughout its life.
- Performance-Based Logistics
- A strategy for cost-effective system support.
also known as Performance-Based Life-Cycle Product Support
Packaging, Handling, Storage & Transportation
Program strategy for safely packaging, handling, storing, and transporting a Product or related material as well as any special requirements and interfaces with organizations responsible for transporting.
The PHST plan is generated in the IPS element “Logistic Related Operations”.
An instance of a System with milestones
Project X will start in MM/DD/YYYY, its Milestone A is MM/DD/YYYY, and will be ready for depoyment at MM/DD/YYYY.
Reliability Centered Maintenance
1. Choose the asset you want to evaluate
2. Evaluate the chosen asset
3. Choose the type of maintenance to perform (preventive, proactive or condition-based).
4. Repeat the RCM process for other equipment or critical assets.
A prediction method whose output is a real number, that is, a value that represents a quantity along a line.
Predicting the temperature of an engine or the revenue of a company.
A system is resilient to the degree to which it rapidly and effectively protects its critical capabilities from disruption caused by adverse events and conditions.

An extension of life span through structural parts exchange.
Main stringer or longeron substitution.
To solve = to find an answer to a problem
To resolve = make the problem go away; bring an end to the issue
One can resolve to solve it, but it won’t be solved instantly. But once the goal is reached, then the issue is resolved, and the problem solved.
a construct or collection of different elements that together produce results not obtainable by the elements alone.
a group of interacting or interrelated entities that form a unified whole.
- Respiratory system
- Hydraulic system
- Anti-collision System
- is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.
an interdisciplinary field of engineering that focuses on the design and management of complex engineering projects over their life cycles (SX000i).
deals with work-processes, optimization methods and tools to manage risks in such projects, overlapping with both technical and human-centered disciplines, such as control engineering, industrial engineering, organizational studies, and project management.
Systems Engineering ensures all likely aspects of a project or system have been considered and integrated into a whole.
An atomic activity (can not be subdivided).
A task has a Start and an End.
A Task is part of the IPSP.
Some action required directly in the System is called a Job.
Total Ownership Cost or Total Cost of Ownership
The total cost of ownership includes the purchase price of a particular asset, plus operating costs over the asset's lifespan.
Looking at the total cost of ownership is a way of assessing the long-term value of a purchase to a company or individual.
consists of all elements that are part of the Life Cycle Cost (LCC) plus the indirect, fixed and linked costs. These can include items such as common support equipment, common facilities, personnel required for unit command, administration, supervision, operations planning and control, and fuel and munitions handling.
Minor improvement, does not change version or model.
A new access window in the fuselage
Major improvement with change on version or model
A wing tip installation, a flap extension, etc.
