Artificial Intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalise, or learn from past experience.

Computerised Maintenance Management System (CMMS), also known as Computerised Maintenance Management Information System (CMMIS), is a software package that maintains a computer database of information about an organisation’s maintenance operations.  This information is intended to help maintenance workers do their jobs more effectively (for example, determining which machines require maintenance and which storerooms contain the spare parts they need) and to help management make informed decisions (for example, calculating the cost of machine breakdown repair versus preventive maintenance for each machine, possibly leading to better allocation of resources).

Enterprise Resource Planning (ERP) is the integrated management of core business processes, often in real-time and mediated by software and technology.

ERP is usually referred to as a category of business management software — typically a suite of integrated applications—that an organisation can use to collect, store, manage, and interpret data from these many business activities. Wikipedia

The Internet of Things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled.

The definition of the Internet of things has evolved due to convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and others all contribute to enabling the Internet of Things.

Machine Learning (ML) is the scientific study of algorithms and statistical models that computer systems use to effectively perform a specific task without using explicit instructions, relying on patterns and inference instead. It is seen as a subset of artificial intelligence. Machine learning algorithms build a mathematical model of sample data, known as “training data”, in order to make predictions or decisions without being explicitly programmed to perform the task. Wikipedia

Manufacturing Execution Systems (MES) are computerised systems used in manufacturing, to track and document the transformation of raw materials to finished goods. MES provides information that helps manufacturing decision makers understand how current conditions on the plant floor can be optimised to improve production output. MES works in real time to enable the control of multiple elements of the production process (e.g. inputs, personnel, machines and support services). Wikipedia

Predictive Maintenance (PdM) is a popular application of predictive analytics that can help businesses in several industries achieve high asset utilisation and savings in operational costs.

PdM directly monitors the condition and performance of assets during normal operation to reduce the likelihood of failures. It attempts to keep costs low by reducing the frequency of maintenance tasks, mitigating unplanned breakdowns and eliminating unnecessary preventive maintenance.
