Session 8: Future Technologies III: The Factory of the Future Workshop 8.1 | Organization in Production Lean production systems – Streamlining production and logistics Dr. Stephan Keßler | Essen, 05.11.2010 Agenda 1. Definitions, structure and background of Lean Production Systems (LSP) 2. Dimensions of dissemination 3. Typical elements of LSP and exemplary consequences for production organisation 4. Conclusion and future challenges Dr. Stephan Keßler | Essen, 05.11.2010 2 Understanding and objectives of lean production systems (LPS) Definitions • LPS are operating instructions for the production of products and services and support the planning, operation and continuous improvement of production processes. Innovative organizational concepts/components that have proven to be a best-practice solutions, are matched in an overall system. /Fraunhofer IAO/ • LPS can be understood as a dynamic network of design principles, methods and tools for the planning, operation and ongoing improvement of business processes. It is run with a high degree of employee participation. /MTM/ Objectives Structuring, describing and quantifying the strategies, methods and instruments / tools associated with the value creation process Representation of interlinkages and interdependencies between the individual components Establish transparent and comprehensible but also flexible standards for the entire company Management philosophy Focussing on overall optimization of production instead of pursuing solutions for single point optimizations Dr. Stephan Keßler | Essen, 05.11.2010 Methods (Poka Yoke, production levelling, Milk Run & supermarkets, Kanban, Kaizen, 5S, PDCA, Jidoka, FMEA,…) Tools (manual, operating instructions, team meeting, Schulungen, brainstorming, maintenance plan, Kanban-card, workshops, interview, qualification matrix, KPI-board, audit check list,…) Dr. Stephan Keßler | Essen, 05.11.2010 also called: elements / sub-systems / modules / field of action • Functions to achieve corporate objectives • Bundling of methods Also called: components / concepts • approaches to implement the single principles operative production management Principles (process orientation, pull, prevention of errors, flexibility,…) strategic production management specification Objectives (delivery, costs, quality) normative production management Structure of lean production systems Also called: instruments / techniques • Supporting implementation of methods Phases of development of lean production systems Taylorism REFA Lean Thinking Division of labour Assembly line production Toyotism Standardisation Mass production Fordism Toyota produktion system (TPS) Lean… Management Production Administration Manufacturing Volvoism Group work decentralisation Processes Innovative work organisation 1920 1940 Dr. Stephan Keßler | Essen, 05.11.2010 1960 1980 • Integration of isolated elements of production organization • Applicability in all business areas (not fixed to production) LSP • Origin: automotive industry, especially TPS • Applicability to all industries / business types Examples for the structure of LPS of some companies Toyota production system Total Quality Control (TQC) Just-in-Time (JIT) Jidoka (Autonomation) Total Quality Control (TQC) Mitarbeiter fördern + fordern Stetige Verbesserung + Standardisierung Beherrschte Lieferkette HelPS Null Fehler Cost reductions by systematic avoidance of waste Effizienter Produktanund -auslauf Flexible production MAN-Production System (MNPS) Hella Production System (HelPS) Bosch Production System (BPS) Dr. Stephan Keßler | Essen, 05.11.2010 Mercedes Benz-Production System (MPS) Levels of dissemination of lean production systems Sectors … Service providers Industry Branches Automotive Mechanical Engineering Electronics … Process industry Level of added value OEM Tier 1 Tier 2 … Tier n Business processes Production Dr. Stephan Keßler | Essen, 05.11.2010 Production related processes … Product / process design Administration processes Value chain-wide dissemination of lean production systems Gegenwärt iger Current focus of Schwerpunkt impact der GPSWirksamkeit of Lean Production Systems LogistikLogistics dienstService Providers leister (LSP) (LDL) … th-tier supplier n Zulieferer n.-Stufe Zulieferer 1.-Stufe 1st-tier supplier OEM Wholesaler Großhandel Industrielle Logistik Industrial Logistics Commercial Logistics Handelslogistik Dr. Stephan Keßler | Essen, 05.11.2010 Retailer Handel Endkunde Final customer Infrastructure Human Ressources Reserach & Develpoment Procurement Incoming Logistics Manufacturing Outgoing Logistics Current focus of impact of Lean Production Systems Dr. Stephan Keßler | Essen, 05.11.2010 Marketing and Sales After Sales Margin Primary processes / direct processes Supporting processes / indirect processes Inter-organizational dissemination of lean production systems Future traget / postulation: application of production system principles to all business processes Vehicle Manufactureres Fahrzeugherst eller Suppliers Zulieferer Other Sonst igebranches Branchen Interbranch dissemination of lean production systems Eisenach 1940- 1960 1990 t 1992 1994 1996 1998 2000 2002 2004 2006 2008 Dr. Stephan Keßler | Essen, 05.11.2010 Sources: /WINN02, DOMB05, own research/ Cross-sector dissemination of lean production systems Logistics Service Provider (LSP) consignor Processes (e.g. development, Manufacturing) Interface processses (e.g. packaging, manufacturing) Increasing requirements: e. g. more complex process control, hiher flexibility, shorter time for reaction, integration to customer/supplier-processes...

Do you have any questions or remarks? Dr. Stephan Keßler | Essen, 05.11.2010
