Process technology Supply network relationships Capacity Market competitiveness Decisions On being a supply network manager : On being a supply network manager What are Supply Networks? : What are Supply Networks? supply networks vs. supply chains buyer-supplier relationship a supply network is a system of organisations connected by server-client links - upstream/downstream - that service processes & activities (operations) bringing added value to each client and ultimately the end customer. Flows of products, services & information : Flows of products, services & information second-tier suppliers first-tier suppliers first-tier customers second-tier customers For Company A Internal supply network Immediate supply network Total supply network Company B Company C X X X X X Supply side Demand side Up stream Down stream Measuring Supply Chain Performance : Measuring Supply Chain Performance Delivery Quality Time Cost Structural Improvement : Structural Improvement Basic Ways to Improve Supply Chain Structure: Change structure Capacity, Facilities, Process technology, vertical integration Change infrastructure People, Information systems, Organization, Production and inventory control, Quality control systems Forms of Structural Change : Forms of Structural Change Forward and Backward Integration Major process simplification Changing the configuration of factories, warehouses, or retail locations Major product redesign Outsourcing logistics to a third party. Supply relationships : Supply relationships a company can trade with first tier and second tier customers at the same time - but consider the % balance of each immediate suppliers vs suppliers of suppliers in the total network relationships between companies in the network need not be exclusive - multi-sourcing. Company C - seems to single source (exclusive supply) item X Types of relationship: close and intimate? Make or contract in (outsource)? What items: strategic, trivial? Many suppliers or a few. Keiretsu? Transactional (arms-length only) or collaborative? Loyalty in buyers and sellers markets? From Aggregate to MPS to MRP1 : Forecast random orders Master production schedule (MPS) MRP1 Design changes Bill of material Stock movements Inventory record Reports 10 Aggregate Plan (product groups) Firm orders From Aggregate to MPS to MRP1 Time-phased plan how many + when we will build each end item. MRP2 Slide 11: Material Requirements Planning dependent demand info. system to determine No. of parts, components, materials needed for a product order scheduling information - dates when orders for materials should be released, based on lead times. batches of materials, parts, components should be ordered/produced based on a master production schedule (MPS) Inventory Records Data : Inventory Records Data Bill of Materials complete product description materials parts components production sequence modular BOM subassemblies planning BOM fractional options Inventory record status according to “time windows or buckets” identify each parent item that created demand Slide 13: Product Structure Tree for Assembly A from bill of materials Lead Times A 1 week B 2 wks C 1 wk D 3 wks E 4 wks F 1 wk Demand wk 10 50 A wk 8 20 B (Spares) wk 6 15 D (Spares) No. of components for each product + when needed.
