Machine Data

The term "machine data" refers to digital information that is generated by computers, mobile phones, embedded systems, and other devices connected to a network. This type of data has become increasingly common with the advancement of technologies like radio frequency identification (RFID) and telematics. Moreover, the rise of the Internet of Things (IoT), Hadoop, and other big data management technologies has further emphasized the importance of machine data.

Machine learning

Machine learning is a branch of artificial intelligence that focuses on enhancing statistical models by utilizing past data. This improvement process, known as training, is facilitated by a learning algorithm. Once the model has been trained, it can be utilized to address the same kind of tasks that were covered by the training data. As a result, machine learning offers a substitute for explicit coding of a function.

Machine learning on the edge, distributed machine learning

Distributed machine learning is a technique used when it is not desirable to transmit local data to a central server for the purpose of machine learning. This approach enables local nodes to train models locally and then periodically send the models to the central server. Once there, the models are combined and then redistributed to the local nodes for further use.

Managed Service Provider

An MSP, or managed service provider, offers various network, system, application, and e-management services to numerous enterprises through a network, using a pricing model where customers pay only for what they use. A "pure play" MSP concentrates primarily on providing management services. The MSP industry also encompasses services from other providers, such as ASPs (application service providers), web hosting companies, and NSPs (network service providers), who supplement their standard services with management services.

A Kubernetes manifest is a description of a Kubernetes API object in YAML or JSON format that specifies the desired state of the object. When a manifest is applied to a Kubernetes cluster, Kubernetes will ensure that the actual state of the object matches the desired state specified in the manifest. A single configuration file can contain multiple manifests for different Kubernetes objects.

Manufacturing as a Service

Manufacturing as a Service (MaaS) refers to the use of networked manufacturing infrastructures for producing goods on-demand. The customer initiates the production of goods by the manufacturing companies through MaaS, and the order assignment is fully automated. This allows the customer to avoid spending significant amounts of time searching for suitable suppliers with the right skills and capacities. Instead, they can use an efficient algorithm that selects the best possible supplier based on certain factors. MaaS also benefits suppliers by allowing them to focus on their core manufacturing business while handing over the administrative work of customer acquisition and order processing to MaaS. For more information, please refer to the team landing page on Manufacturing as a Service (MaaS).

Manufacturing Bill of Materials

The manufacturing bill of materials is a product of the planning process, which includes auxiliary materials. It is a comprehensive list of all required parts and their respective quantities needed for the production of a product or assembly. However, due to site-specific manufacturing variations, the list may differ slightly within the eBOM specifications for each site.

Mapping - Logic

Mapping, also known as matching, involves aligning the semantics and attributes of capabilities with skills. This is done by comparing the requirements of the product or customer (i.e., capabilities) with the capabilities of the machine or service provider (i.e., skills). Mapping can be done at different levels of detail, and the result is a list of modules that either fit or do not fit. This list can then be further filtered and prioritized based on additional criteria, such as which modules fit best, are most cost-efficient, or offer the best quality.

MapReduce (Batch Processing)

The term "Batch Processing" refers to the automatic, sequential, and complete execution of data contained in input files. The program runs independently, without user intervention, after being initiated. The data to be processed is handled one by one. The results can be stored, for example, in files or databases. Apache Hadoop MapReduce is a common example of batch processing in Big Data.
