Research Evidence

Aim: Can Colored Petri Nets be effectively applied to model and optimize corrective maintenance decision-making for textile machinery?

Method: Modelling and Simulation

Procedure: The study involved applying Colored Petri Nets (CPN) to model the corrective maintenance process of a conical machine in the textile industry. This included defining the states, transitions, and token flows within the CPN to represent the various tasks and decision points involved in maintenance.

Context: Textile industry, industrial machinery maintenance

Design Principle

Formal process modeling enhances operational efficiency and decision-making accuracy.

How to Apply

Use CPN to map out the steps, decision points, and resource dependencies for any critical operational process, such as product assembly, quality control, or even user onboarding.

Limitations

The study focused on a single type of machine (conical machine) and a specific maintenance type (corrective), which may limit generalizability to other machinery or maintenance strategies.
