Types Of Mfg Systems 6k374n

TYPES OF MFG SYSTEMS INTRODUCTION: Producton system is one of the major component of management. It is affected by internal factors of the factory and also external factors. It coordinate other d ivisions in the factory. Internal factors are:Engineering for product quality Research & Development for Product development Extenal factors are:-Government -Compitition -Technology -Economic Conditions PRODUCTION SYSTEMS: THE FOLLOWING ARE THE IMPORTANT PRODUCTION SYSTEMS:1.Intermittent production system 2.Continous production system 3.Concurrent production system 4.Degenerate production system OBJECTIVES: To understand- productions systems -manufecturing strategies -How production sytems are linked with Mfg strategies and to understand overall production management PRODUCTION MANAGEMENT: By Syncronising producton techneques, The Production Management wants to achive -Superior Quality Production -Higher productivity -Perfect Delivery Performance -Overall Customer Satisfection TYPES OF PRODUCTION SYSTEMS 1.ON-OFF PROJECTS 2.JOB SHOP 3.BATCH PRODUCTION 4.ASSEMBLY LINE 5.CONTINEOUS FLOW 6.FLExible mfg system ONE OFF PROJETS -This is based on customization ie Customer need is criteria EG: L&T Its business executing projects. Work is carried out at site rater than in factory. Equipment is placed at the site itself. JOB SHOP Eg Commercial Printing Firms -Machine Shops -Die making Etc Job Shop Production system processin small batches of large number of different cvproducts. Most of this system require different set of â processing steps. Highly s killed labour is used in this process. BATCH PRODUCTION: Eg: GE Manufecturers medical quipment ECIL mfg computers etc Electronic devises In this production of different parts ar repeated at regular intervals.This is l ike standardization job shop. ASSEBLY LINE: Eg Maruthi makers cars ECIL Eflectronic equipment etc

This is a mass production process. Cotineous pre determined proction steps are followed. Product moves from one work station to another work station at at controlled rat e. Special purpose tools and equipment is normally used. CONTINOUS FLOW EG FOOD PROCESSING INDUSTRY In this System most bulkproducts are manufactured using continuous flow producti on. Process is highly automated. Other xample are RElience Petrochemical complex NTPC thermal power plants FLEXIBLE MFG SYSTEMS Eg: Marithis cars FMS generally consist of large number of CNC Machine Tools. It is controlled by one or more of dedicated computers.FMSfunction without human intervention.It is functioned according to market conditions. For example FMS produce a part or an item when there is demand in market otherwise not.Mfg Flexibility system enable s to respond production at reasonable costs and takes necessary changes in exter nal and internal environments. Mix flexibility enables presentation of wide range of products. Change over flexibility introduces large varity of design changes. Volume flexibility is also exists im FMS. Maruthi Mfrs can easily switchover from production huge batches of one model to another model with required material. PRACTICE DIAGRAM IN PAGE 53
