What is preventive and predictive maintenance?

What is preventive and predictive maintenance?

Preventive maintenance (PM) is work that is scheduled based on calendar time, asset runtime, or some other period of time. Predictive maintenance (PdM) is work that is scheduled as-needed based on real time conditions of assets.

What is the component required for predictive maintenance?

Some of the main components that are necessary for implementing predictive maintenance are data collection and preprocessing, early fault detection, fault detection, time to failure prediction, maintenance scheduling and resource optimization.

What is the difference between predictive and condition based maintenance?

The primary difference between them is the way in which maintenance is measured. In this way, predictive maintenance is a very exact form of maintenance because it predicts future maintenance events. On the other hand, condition-based maintenance relies only on real-time sensor measurements.

What is the meaning of predictive maintenance?

Predictive maintenance is a technique that uses data analysis tools and techniques to detect anomalies in your operation and possible defects in equipment and processes so you can fix them before they result in failure.

What is an example of maintenance?

The definition of maintenance is providing support or upkeep to something. An example of maintenance is a janitor keeping a school clean.

What is maintenance process?

Maintenance procedures are written instructions that, when followed by the maintenance personnel, will ensure that equipment operates as designed within safe operating limits. From: Process Risk and Reliability Management (Second Edition), 2015.

How do you control maintenance costs?

Maintenance cost reduction strategies

1. Review all maintenance procedures & simplify them.
2. Understand and follow safe work practices.
3. Better management of very unpredictable unplanned or breakdown maintenance.
4. Create a maintenance calendar of scheduled work in the next month, quarter or year for critical equipment.

Which tools are used in implementation testing and maintenance?

Lower Case Tools – Lower CASE tools are used in implementation, testing and maintenance. Integrated Case Tools – Integrated CASE tools are helpful in all the stages of SDLC, from Requirement gathering to Testing and documentation.

What kind of support is provided by the code editing CASE tool?

Where is Case tool used?

CASE tools are used for developing high-quality, defect-free, and maintainable software. CASE software is often associated with methods for the development of information systems together with automated tools that can be used in the software development process.

What are reasons for using CASE tools?

Computer-Aided Software Engineering (CASE) technologies are tools that provide automated assistance for software development . The goal of introducing CASE tools is the reduction of the time and cost of software development and the enhancement of the quality of the systems developed.

Which is not a type of CASE tool?

Testing tool

How are CASE tools classified?

CASE tools can be classified into 3 categories: front-end, back-end or cross life cycle CASE products, according to when they are used during systems development. Front-end tools, sometimes called upper-CASE tools, are used during preliminary investigation, project planning, analysis or design.

Is UML a CASE tool?

UML tools are often part of computer-aided software engineering (CASE), which aims to create source code as automatically as possible and to maintain finished software products automatically.

What is a case repository?

A CASE Repository should be the representation, in data, of all relevant informa- tion about the system under development, in a consistent, complete form which is independent of its mode of entry and modification or subsequent use.

• Reduced cost.
• Better performance.
• Improved service.
• More information.
• Stronger controls.
• Support for new products and services.

What is the difference between upper and lower CASE tools?

Because of their similarities, sometimes Upper and Middle CASE are simply referred as Upper CASE. Generally, Upper CASE is a tool for high level view of software development whereas lower CASE is mostly being used as a tool at the programming and testing phase.

What are CASE tools What is a case repository and how is it used?

The repository stores the knowledge from the multiple tools in an integrated manner, and is accessible to all tools throughout the entire development life cycle. Upper CASE tools are designed for the early stages of the SDLC, and are used for project planning, systems analysis and general systems design.

What are the advantages and disadvantages of CASE tools?

• Increased Speed. CASE Tools provide automation and reduce the time to complete many tasks, especially those involving diagramming and associated specifications.
• Increased Accuracy.
• Reduced Lifetime Maintenance.
• Better Documentation.
• Programming in the hands of non programmers.
• Intangible Benefits.

What is the central component of any CASE tool?

The central component of any CASE tool is the CASE repository, otherwise known as the informationrepository or data dictionary. The CASE repository stores the diagrams and other project information, such asscreen and report designs, and it keeps track of how the diagrams fit together.
