Paper one “IDEF*: a comprehensive modeling methodology for the development of manufacturing enterprise systems” [1] discusses the IDEF* modeling methodology which is used to reduce the incompatibility between the models and help modeling maintenance. The paper also gives information on the structure and various components of the supporting software tool that is used. Paper two “A knowledge-based approach to the generation of IDEF0 models” [2] discusses IDEF0 modeling. It explains how IDEF0 modeling can be used for modeling manufacturing systems. Knowledge-based system approach is explained so as to automate the modeling processes in order to reduce the modeling time and maintain consistency. Paper three “Implementing IDEF Techniques as Simulation Modelling Specifications” [3] explains IDEF0 modeling and gives information on simulation and how IDEF can help in simulation processes. The paper also discusses a case study in brief to explain IDEF modeling and in its implementation in simulation. What I expected from these articles: I expected these articles to give detailed information on IDEF modeling and explain how they could be used in any enterprise. I also expected to learn different IDEF methods and methodology. I hoped that the case study would explain to me in detail how the problem was approached and solved using the IDEF modeling techniques. Introduction: A model is one of the best techniques to represent an enterprise and its allied processes. Modeling helps in the analysis and design of an enterprise or its processes. Thus, in turn reduces the cost and time that would be wasted due to wrong implementation of the process. Models reduce the complexity and thus helps in better understanding. It can help in communicating the information to all types of people. IDEF is one such method of modeling. It consists of different methods such as IDEF0, IDEF1, IDEF3 and many more. Article 1: “IDEF*: a comprehensive modeling methodology for the development of manufacturing enterprise systems” (Ang, 1999). Computer Integrated Manufacturing Open System Architecture (CIMOSA) reference architecture suggests four complementary viewpoints namely function, information, resource and organization to view a manufacturing enterprise. When modeled from each viewpoint it causes repetitive capturing of same information, difficulty in identifying the changes and communication. IDEF*, a comprehensive modeling methodology is developed along with is supporting software tools. This
