Models and Analysis of Production Systems 8/24/04 Paul A. Jensen Operations Research Models and Methods Copyright 2004 - All rights reserved Production System Design Manufacturing - (Latin - produce by hand) Production - Broader word - Something that is produced by physical or intellectual labor Products - Goods - Services - Poems Two words are practically synonyms; making something someone wants We are dealing with organizations that produce a good or service 2 Production System Design System: Collection of components that accomplish production Design: Provide the detailed specification for the components The IE designs and operates the system of production 3 The functional nature of business Business Design Product Design Schedule Design Distribution Design Service System Design Process Design Machine Design Production System Design Control System Design Facility Design 4 Hierarchical issues make integrated design difficult A particular design problem falls within a hierarchy of designs The design activity must recognize impacts on other levels The design affects operations 5 The hierarchy of design Product Mix Plant Layout Assembly Line Path of a tool 6 Interactions within the levels of the hierarchy Preceeding Design and Operation Constraints and Measures Performance Design Activity Constraints and Measures Performance Following Design and Operation 7 The hierarchy between design and operation Design Measure Operate Results Control 8 Providing integration through models Situation Formulate the Problem Implement a Solution Problem Statement Data Construct a Model Implement a Solution Model Solution Find a Solution Establish a Procedure Test the Model and the Solution Tools Solution 9 What this course will do: Provide an understanding of problems and issues in production system design Build models to describe the components of production processes Build models to describe the system of production Use operations research tools to analyze models and make decisions Identify, quantify and alleviate waste in the manufacturing process 10
