Introduction to Industrial Engineering Dr M Vijaya Kumar Asst. Professor TIU Erbil Definition Industrial and systems engineering is concerned with the design, improvement and installation of integrated systems of people, materials, information, equipment and energy. It draws upon specialized knowledge and skill in the mathematical, physical, and social sciences together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results to be obtained from such systems. --- IISE Broad Areas What we do?

Journal of Computational & Applied Research in Mechanical Engineering (JCARME) Production planning and control International Journal of Advanced Manufacturing Technology Productivity Very simply, Productivity = Output Input For any type of organization Definition: Productivity is the relationship between the outputs generated from a system and the inputs that are used to create those outputs. 12 Basic Definitions of Productivity Measure Partial Productivity Measure Partial Productivity is the ratio of output to one class of input. Labour productivity = output / labour input Total-factor Productivity Measure Total-factor Productivity is the ratio of net output to sum of associated labour and captial (factor) inputs. total-factor productivity = net output / (labour and capital input) Total Productivity Measure Total Productivity is the ratio of total output to the sum of all input factors. Total productivity = total output / total input Both the output and input(s) are expressed in real or physical terms by being reduced to constant rupees of a reference period (base period). Example for productivity measure For a company XYZ, the total inputs and outputs have been
