7 Material Requirement Planning Emerged from BOMP in 60sConversion of production plan for parent items (finished products) into a production plan of production or purchasing for component itemsExplosion of the requirements for a top level item through the BOM to generate component demandExecuted at each level of Assembly / sub-assemblyDiscrete Manufacturing: Manufacturing items based on a definitive bill of material or recipe as opposed to batch formulas. The bill of material or recipe is typically expressed in quantities per each as opposed to percentage per batch.
8 Principles of MRPSystem to plan and control production and material flowscore principle:demand for material, parts and components depends upon the demand for finished productChain of causality from finished goods back to inventories:possible to reduce inventory to the minimumplan for procurement based on actual needsable to cater for “lumpy” (i.e. dependent) demand
9 BOM = Recipe or formula How to produce our products List of components including possible substitutesHow much of eachSpecial conditions of operationExpected yields and labour productivity (i.e. standards)Extrapolate a cost per unitStored in a Bill of Material (BOM)
10 Example: Bill of Material for desk 1 – List out the components2 – describe the steps required for assembly3 – arrange them in a possible manufacturingsequence

12 How MRP worksMaster production schedule: drives the system based on customer ordersBill of material (dependent demand)Inventory status fileMRP package - contains the logicSee diagram next page

15 Benefits of MRPUnderstanding the implications of changes in production schedule (by de-expediting parts)Keeping inventory low (25% decreases reported) while removing risk of stock-outsBetter planning leading to:reduction in lead timesbetter use of capacitylowered risk of obsolete production (e.g. engineering firms)Early warning system: earliest delivery dates are known before promises are made
18 Integration of design and manufacturing integration of operations with upstream design activities and downstream sales activitydownstream: e.g. by integrating CAD with Bill of Materialnew designs go on-line immediatelyno production of obsolete products / assembliesshorter time to market for new pdts
19 The Rise of MRPSnowball effect as companies moving to MRP imposed business changes to their partnersMRP logic was always around, but switching costs in manufacturing made it worthwhile:data processing costs decreasinginventory costs risingSophisticated CIM systems easier to justifyOther external pressures mean that tighter control is required
