The concept of digital twins and digital shadow is crucial in Industry 4.0, facilitating the organized structuring of diverse data from various sources. A digital twin is a precise, real-time digital representation of reality. It replicates the information of a physical system, product, person, or equipment in a digital format. This digital copy simplifies information access and maintenance planning.

Digital Shadow is a representation of a process, service, or production chain with its characteristics and Maintenance Activity Rules. MOM4 incorporates a library of these rules, defining what’s needed for proper maintenance tasks. It outlines Maintenance Operations Definitions and process steps, organized in sequential or parallel routes that conclude with status reports. Resources are categorized to define Maintenance Operations, with some instructions generated automatically based on rules.

Digital twins provide insights into assets and processes beyond direct measurements. They offer instant insights without complex data handling, fostering consistent understanding across the organization. Digital twins promote agility and alignment across the business, spanning engineering, operations, supply chains, facilities, and more.. 

To prepare a maintenance order for execution, a suitable maintenance definition is linked to it either manually or automatically based on predefined criteria. This definition includes information about spare parts, personal and operational instructions.

Maintenance dispatches transfer orders and accompanying maintenance instructions to the relevant workplace or maintenance team. Maintenance Dispatcher responds to events triggered by tracking events or user requests. Maintenance orders progress through various stages in the activity chain, and the detailed maintenance schedule can be recalculated if unexpected process events occur.

The maintenance schedule function organizes activities based on priorities, technical requirements, Maintenance Operations Definitions (e.g., Standard Operating Procedures), and Equipment Definitions for each asset. This sequencing minimizes inspection and repair time.

Maintenance capability information compiles data about all maintenance resources within a selected site, area, process cell, production unit, or production line, including equipment, materials, personnel, and machine centers. 

Efficiently managing spare parts inventory is crucial for a maintenance organization. Poor inventory management can lead to excessive spending on spare parts or costly machine downtime. Optimizing the spare parts inventory control system is a valuable process that contributes to the smooth operation of maintenance activities, and MOM4Maintenance offers features to streamline this process.

MOM4Maintenance’s Inventory modules keep track of materials required for maintenance tasks. It maintains information on stocked items, generates purchase requisitions and purchase orders for non-stock items, and manages requests for reserving stock items while also providing reports on allocated items for work orders.

MOM4Maintenance works to balance two opposing objectives:

• Maximizing the availability of items for upcoming work tasks
• Reduce excess inventory balances and related carrying costs

The goal is to find a balance of inventory stock that lets maintenance work be performed with minimum delays due to unavailable materials, without keeping unnecessary or seldom used items in stock.

MOM4 Reports is a versatile reporting system that provides insights into data management and overall production. It allows data input from various operations and offers the flexibility to generate system-contained reports or customized reports created by users.

These reports are built using Microsoft web parts technology, which enables users to modify web page content, appearance, and behavior directly from a browser. This personalization feature can be applied globally or for individual users, allowing dynamic adjustments without developer or administrator intervention.

Key Performance Indicators (KPIs) are high-level measurements used in business units or departments. They typically include reports, spreadsheets, or charts presenting critical information relevant to the department’s success. KPIs offer a regular, high-level view of a department’s health through visual statistical information, aiding business managers in decision-making.
