OPTIMIZATION OF MULTISTAGE MANUFACTURING SYSTEMS

Abstract

Manufacturing is nothing but conversion of raw materials into finished products in single or multiple stages. Production of most complex parts requires a manufacturing process which consists of multiple of operations and the part has to pass through a series of machines in order to be manufactured. Present work aims at optimisation of a multistage manufacturing system which involves modeling of the system followed by optimisation. In this approach, first a Petri Net Model has been built and is anlaysed with the object of minimising the Work-In-Process. Then the above modelled system is evaluated (optimised) by using dynamic programming technique and this approach is illustrated with an example. A software has been developed for the above process and when required machines can be fixed in any order in order to obtain particular type of product
