Use of Operations Management (OM) in external environment (main target) General knowledge of OM methods acquired at university and long-standing experience Knowledge of methods and experience from research and literature - teachers Knowledge of methods and experience from outside world – consultants, managers, … Extent of knowledge Extent of knowledge OM all around us OM is the management of all processes used to design, supply, produce, and deliver valuable goods and services to customers TQM = Total Quality Management MRP, JIT, APS, Lean Manufacturing, Little´s law ERP: Marketing, Selling, Invoicing, Payment,…. ERP: Logistics, Transportation , Selected OM methods, which will be kicked around as time will move on •Theory of Constraints -(AOMA-AOPR) •Balanced Scorecard -(AOMA-AOPR) •Project Management methods (Critical Chain) -(AOMA-AOPR) •Material Requirement Planning (MRP) and Just-in-Time principles • -(AOMA only basics-AOPR more in detail) • Advanced Planning and Scheduling (APS) (AOPR only basics) •Six Sigma – quality management -(AOMA-AOPR) •Boston, SWOT and Magic Quadrant Matrices -(AOMA-AOPR) •Little´s Law (relations between WIP, Throughput and Cycle time) -(AOPR) •Linear programming – optimisation -(AOPR) •Yield Management -(AOPR) •Kepner-Tregoe (support of decision making) -(AOMA-AOPR) •Decision trees -(AOPR) • • • • Some tools which have to be used •ERP-Enterprise Resource Planning (MS Dynamics NAV) –Basic installation, handling and setup –Inventory – Items – Transports –Availability of components –Purchase –dealing with Suppliers (SCM) –Selling – dealing with Customers –Payment – bank operations –Accounting basics –CRM- Customer Relationship Management –Manufacturing – Planning and Shop Floor Control –Cost management – – • • • Serves as the magnifying glass to processes… Controlling processes in Supply Chain Management (SCM) Supply Production Orders Operation Strategies and Innovations , R&D Forecasts, Blank Orders Long term planning Marketing Logistic operations Routing control, TQM Packaging , Transportation MRP, Replenishment MRP_II ; JIT, Capacities Cash flow Strategic Operational Tactical Operational Used abbreviations : R&D –Research and Development; TQM-Total Quality Management; JIT- Just –In-Time; MRP_II-Manufacturing and Resource Planning Used abbreviations (slide number 3 ): : ERP - Enterprise Resource Planning ; APS – Advanced Planning and Scheduling , MRP-Material Requirement Planning Deming cycle (based on periodicity) Plan: Define the problem to be addressed, collect relevant data, and ascertain the problem's root cause (e.g. by use of TOC=Theory of Constraint) Do: Develop and implement a solution; decide upon a measurement to gauge (assess) its effectiveness. Check: Confirm the results through before-and-after data comparison. Act: Document the results, inform others about process changes, and make recommendations for the problem to be addressed in the next PDCA cycle.

(one of many) momentus 33e68905-3e3e-4556-bc5b-c5e41f6527fa_Pakistan_Musharraf • •We have •a huge data •quantity 33e68905-3e3e-4556-bc5b-c5e41f6527fa_Pakistan_Musharraf • •Moore's law is the observation that the number of transistors in a dense integrated circuits doubles approximately every two years – so -> capacity of memory is going up Big data and analysis problem In test and measurement applications, engineers and scientists can collect vast amounts of data every second of every day. •For every second that the Large Hadron Collider at CERN runs an experiment, the instrument can generate 40 terabytes of data. •For every 30 minutes that a Boeing jet engine runs, the system creates 10 terabytes of operations information. •For a single journey across the Atlantic Ocean, a four-engine jumbo jet can create 640 terabytes of data. •Multiply that by the more than 25,000 flights flown each day, and you get an understanding of the enormous amount of data that exists (Rogers, 2011). That’s “Big Data.” CERN = Conseil Européen pour la Recherche Nucléaire –Resource : https://home.cern/about Hardon Collider-accelerator •To solve it we should use finite capacity scheduling (APS)- will be presented later improve01_01 •Op1 •Op2 •Op3 Zobrazit obrázek v plné velikosti press Zobrazit obrázek v plné velikosti •T1 •T2 • T1+T2=X • •Opt=Min(X) •Op1 •Op2 •Op3 •T1 = 0 •T2 = 0 • Basic problem III.
