Expanding DRM Framework to Formulate Supreme Causal Models from Research Articles in the Area of Product Disassembly
This study focuses on the implementation of a Causal Model for extracting causal relationships from research articles in the area of product disassembly. A Causal Model is a Model with a network of influencing factors to describe situations, as proposed by the DRM framework. In this work, DRM framework is further aided by formulating Supreme Causal Models. Individual Causal Models were generated using causal relationships extracted from research articles; Supreme Causal Models were formulated by collating these individual Models. The methodology adopted includes the following steps: data was collected from forty research articles in the area of product disassembly, which were analyzed using the concept of Causal Model from the DRM framework. Results include individual Causal Models, extracted from research articles, and Supreme Causal Models. The individual Causal Models elaborate some of the existing situations within the area of product disassembly; the Supreme Causal Models give a more complete picture of these existing situation fragments. Also, they represent some of the potential desired situations, such as maximizing profit or minimizing environmental impacts, and provide insights on how to achieve these desired situations.
