K.M. Corker, Ph.D.Industrial & Systems Engineering What is a System? Group of Components that work together for a purpose –Service –Product –Process

K.M. Corker, Ph.D.Industrial & Systems Engineering How is a System Understood ?? Decomposition Analysis Aggregation More than the sum of its parts –Emergent –Self-organizing –Entropic and Enthalpic A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied by the pressure exerted on it by its surroundings

K.M. Corker, Ph.D.Industrial & Systems Engineering When you decompose what do you get?? Components –Structural –Operating –Flow

K.M. Corker, Ph.D.Industrial & Systems Engineering What is a System Life Cycle System Planning and Marketing Research Development Testing and Evaluation System Acquisition & Deployment & Production

State of a System –Collection of variables that describe a system from a perspective and at specific time –Variation in perspective –Variation in temporal resolution System Engineering Knowledge –Principles –Practices –Perspectives

K.M. Corker, Ph.D.Industrial & Systems Engineering How can system be known?? Thought then has objective validity because it is not fundamentally different from the objective reality but is specially suited for the imitation of it. The fundamental nature of neural machinery lies in its power to parallel or model external events. KJW Craik The Nature of Explanation (Cambridge, 1952)

K.M. Corker, Ph.D.Industrial & Systems Engineering What are criteria for System Quality ?? Efficient & Effective in –Production –Use –Maintenance –Retrofit Other Criteria??
