Operation and maintenance is the stage where you monitor and manage the performance, efficiency, and quality of your waste management system during its use. It is also where you can detect and correct any problems, defects, or failures that may occur in your system. To help with this, there are a number of CAD tools such as MATLAB and Autodesk Fusion 360. MATLAB is a numerical computing tool that enables you to analyze and visualize data, develop algorithms, and create models and applications for your waste management system. It can also be used to process and interpret data from sensors, meters, and controllers that measure the parameters of your system. Additionally, it can be used to develop control strategies such as PID, fuzzy logic, or neural networks to optimize the operation and efficiency of your system. Autodesk Fusion 360 is a cloud-based CAD tool that allows you to create 3D models, drawings, and simulations of your waste management system. You can access and update your system design from any device with this tool, as well as connect it to the Internet of Things (IoT). Moreover, features such as dashboards, alerts, analytics, preventive maintenance, predictive maintenance such as condition monitoring or fault diagnosis can be used to reduce downtime and costs.
