Sate flow modelling and Control of Home Appliance

Abstract 

Modern home appliances are designed to be intelligent, performing complex activities to make our lives easier. However, unexpected failures, such as error codes in automatic washing machines, can be confusing for users. Discrete event models can be used to improve the prediction of appliance behavior and avoid this scenario. These models can help identify the root cause of the error, whether it's a logical deficiency in the appliance's design or a fault in a sensor or actuator. Discrete event modeling can narrow down the possibilities of damaged components and suggest appropriate maintenance actions, such as replacing specific parts or transporting the appliance to a service center. Additionally, these models can supervise the appliance's operation to prevent forbidden states. By leveraging discrete event modeling, the maintenance process can become more efficient, reducing unnecessary service visits and expense.
