Simulatione
Design a model for a real-world system and conduct experiments with this model to evaluate various operational strategies for the operation of the system or understand the operation of the system. Consider modeling and simulation as an integrated concept. A series of processes related to creating correct model data through statistical analysis after constructing (configuring and coding) a model using a computer program
Defining 3D Simulation
Within the production system, which consists of various components such as workers, machines, raw materials, etc
Inefficiency occurs, and if the production system is not operating properly, bottlenecks or machines will be affected
Problems such as excessive idle occur
In order to operate the production system smoothly, we need to continually identify these problems,
If necessary, the system should be improved to reduce or remove it.
Performance Measure shows whether the production system works efficiently
refers to quantitative indicators, and managers of production sites generally have a set of performance evaluation indicators
You want to measure the value to understand the problem, but this may not be easy.
Throughput, Waiting Time, Queue Length, Utilization
Virtual production system by visualizing performance evaluation indicators such as (Utilization) and Lead Time
If you create , you can execute it and calculate the value of the performance evaluation index very conveniently.
Furthermore, the value of the performance evaluation index when the current system is changed or improved using Simulation
It is also not difficult to estimate.
A series of analyses and improvements are made using the tool that implements this
The work is called Simulation

Digital Twin
Real-world machinery, equipment, and objects are implemented in a virtual world inside a computer.
- A virtual model created by General Electric (GE) that is represented equally on physical objects and computers
- Edge Computer converts old equipment or its controls to MQTT, OPC UA Or support the latest protocols such as Jetson
- Create a digital twin of virtualized assets with software instead of physical assets By simulating (simulating), accurate information about the characteristics of the real asset (current state, productivity, operation scenario, etc.) can be obtained.
- Digital twins are used in many industries such as energy, aviation, healthcare, automobiles, and defense From design to manufacturing and service, including asset optimization, minimization of unexpected accidents, and increased productivity It can improve the efficiency of all processes.
