  3. Material Requirements Planning • Identifying stock that planned production calls for • Determine the lead time to get the stock from suppliers • Calculate safety stock levels • Calculate the most cost-effective order quantities • Produce purchase order for needed stock items in the right ammount Peter Dolog, ERP Course, Production and Materials Management Module

  4. Inventory • Goods and Material available at stock for use • Three kinds (for sales): • Raw materials • Work in Process Items • Finished Goods • Some companies also fixed assets (not directly used for sales) • Stored in warehouses or shops for customers • Managed and identified through the stock keeping units (SKUs) Peter Dolog, ERP Course, Production and Materials Management Module

  5. SKU • Is an identifier used for systematic tracking of products and services offered • It is attached to a billable item: • physical (item, variant, product line, bundle) • service, fee or attachment • Different for each variant or packaging of the same product Peter Dolog, ERP Course, Production and Materials Management Module

  6. Inventory Costs • Inventory is an asset on the company balance sheet • Additional costs: • Space to store (e.g. rent) • Insurance • Utilities • Different inventory depriation schemes depending on a country law • These costs can be 1/3 – ½ of the price • Tradeoff: to stock to little and to much • Some companies store more to inflate their apparent asset value Peter Dolog, ERP Course, Production and Materials Management Module

  7. Opportunity Costs • Costs connected with lost opportunity to sell it • Need not to be assessed in terms of monetary value Peter Dolog, ERP Course, Production and Materials Management Module

  8. Inventory Expenditures • When sold, the value of the inventory decreases • Usually value per item • First comes first goes for sales • Last comes last goes sales • Lower income, lower taxes Peter Dolog, ERP Course, Production and Materials Management Module

  9. Inventory in Navision • Item Journal – connection to sales, paurchases • BOM Journal – bills of materials • Item reclassification journal – shifting items between locations and bins • Physical inventory journal – to maintain real values and physical locations of items • Revaluation journal – to change values of items Peter Dolog, ERP Course, Production and Materials Management Module

  10. Warehouse Activities • Bin contents management • Receipts • Shipments • Product orders to manufacture • Restock/Purchase orders • Transfer orders • Item movements and transfers Peter Dolog, ERP Course, Production and Materials Management Module

  11. Capacity Planning • To plan personnel, space, machines, and other production facilities to meet production goals • Requires precise information about human resources, BOM, goods-in-processs inventories, finished goods, lot sizes, status of raw materials, orders in the plant, lead time for orders • Master production schedule from sales forecast • Product design and development information systems Peter Dolog, ERP Course, Production and Materials Management Module

  12. Resource Planning • Pricing for unit of work • Price/Profit calculation • Resource capacities • Allocation to jobs Peter Dolog, ERP Course, Production and Materials Management Module

  13. Strategies for Capacity Planning • Basic capacity plan includes number of workers, machines, shifts, utilization, and efficiency • Tries to deal with differences caused by customer demands and under/over utilized resources • Lead strategy (based on new customers) • Lag strategy (based on reaching maximum capacity) • Match strategy (based on tracking) Peter Dolog, ERP Course, Production and Materials Management Module

  14. Production • Set of customer orders which require products • They issue a request for materials, human resources and machines to perform the production • The production is based on BOM, resource allocation and work and machine centers utilization • The activities in the production results from a product design • The quantities, resource allocation and capacity estimation results from customer orders and sales forecasts Peter Dolog, ERP Course, Production and Materials Management Module

  15. Production Planning • Production forecasts • Planning worksheets • Order planning • Requisition worksheets • Subcontracting Peter Dolog, ERP Course, Production and Materials Management Module

  16. Production Forecasts • How many and which products are planed and in which quantities? • How much does it cost? • Where to get the parts from? Peter Dolog, ERP Course, Production and Materials Management Module

  17. Further plans • Purcahse orders • Subcontracting orders • Decomposition to capacity, resource and warehouse plans • Decomposition into BOM • Routing in the production between work centers and warehousing (production process) Peter Dolog, ERP Course, Production and Materials Management Module

  18. Bill of Material (BOM) • Describes a product in terms of its parts and assemblies • This includes also packaging and labels • Hierarchy with references to other BOMs • Important for parchasing and configuration • Different types of BOMs (engineering BOM, manufacturing BOM, ordered BOM, …) • Different ways to display it (ident, matrix, modular, …) Peter Dolog, ERP Course, Production and Materials Management Module

  19. Production execution • Planned vs. real production time • Measuring and controling activities at the manufacturing floor • Observing productivity and quality • Observing consumption and output • Feedback to production and planning • Adjustments according to changes in sales Peter Dolog, ERP Course, Production and Materials Management Module
