Material Planning
A complete practical framework for demand, forecasting, MRP, BOM, replenishment, lead time, shortages, critical spares and material availability.
FOUNDATION
Demand Planning
Translating production, maintenance, sales and operating requirements into material demand.
Open Reference →Consumption-Based Planning
Using historical consumption, trends and variability to determine future material requirements.
Open Reference →Demand Forecasting
Practical forecasting methods for materials with stable, seasonal, intermittent or variable demand.
Open Reference →Requirement Consolidation
Combining departmental, production, maintenance and project requirements into a controlled material plan.
Open Reference →Gross Material Requirement
Determining total material requirement before considering existing stock, receipts and other available supply.
Open Reference →MRP & REQUIREMENT PLANNING
Net Material Requirement
Calculating the remaining requirement after accounting for available inventory and scheduled supply.
Open Reference →Dependent vs Independent Demand
Distinguishing demand generated by production structures from directly forecast or consumption-driven demand.
Open Reference →BOM-Based Material Planning
Using bills of material to explode finished or intermediate requirements into component material demand.
Open Reference →Master Production Schedule (MPS)
Connecting production plans with time-phased material requirements.
Open Reference →MRP Fundamentals
Material Requirements Planning logic, inputs, outputs and exception management.
Open Reference →MRP Inputs: MPS BOM Inventory & Lead Time
The master data and transaction inputs required for reliable MRP calculations.
Open Reference →MRP Processing Logic
Gross-to-net calculation, lot sizing, lead-time offsetting and planned-order generation.
Open Reference →MRP Outputs & Planned Orders
Interpreting planned orders, purchase requisitions, production proposals and exception messages.
Open Reference →Lot Sizing Methods
Fixed lot, lot-for-lot, EOQ, MOQ and other order-sizing approaches used in material planning.
Open Reference →REPLENISHMENT & INVENTORY PARAMETERS
Lead Time in Material Planning
Supplier, internal processing, inspection and transport lead times and their effect on planning dates.
Open Reference →Safety Stock in Material Planning
Using uncertainty, service requirements and lead-time variability to protect material availability.
Open Reference →Reorder Point & Replenishment Planning
Using reorder point, lead-time demand and safety stock to trigger replenishment.
Open Reference →Min-Max Material Planning
Setting minimum, maximum and replenishment quantities for practical industrial inventory control.
Open Reference →Review Period & Periodic Replenishment
Planning replenishment at fixed review intervals using target or order-up-to levels.
Open Reference →Fixed Order Quantity Planning
Using a defined order quantity whenever inventory position reaches the replenishment trigger.
Open Reference →Fixed Order Interval Planning
Reviewing inventory at defined intervals and ordering the calculated requirement.
Open Reference →MOQ & Supplier Order Constraints
Incorporating minimum order quantity, pack size, batch size, multiples and supplier constraints.
Open Reference →Planned Orders & Conversion
Controlling the conversion of planning proposals into purchase requisitions, purchase orders or production orders.
Open Reference →SPECIALIZED MATERIAL PLANNING
Scheduled Receipts & Open Orders
Using existing purchase and production commitments as part of net material planning.
Open Reference →Inventory Position for Planning
Considering on-hand stock, allocations, reservations, open orders and expected receipts when planning.
Open Reference →Demand Variability & Uncertainty
Measuring variation and selecting suitable planning and safety-stock responses.
Open Reference →Seasonal & Cyclical Material Planning
Planning materials affected by seasonal production, market demand or periodic operating patterns.
Open Reference →Intermittent & Sporadic Demand
Planning low-frequency MRO and spare-part demand without blindly applying average consumption.
Open Reference →MRO Material Planning
Planning mechanical, electrical, instrumentation, safety, lubricant, packing and maintenance materials.
Open Reference →Critical & Insurance Spares Planning
Planning critical materials using consequence of failure, lead time and availability requirements.
Open Reference →Project & Shutdown Material Planning
Time-phased planning for projects, annual shutdowns, overhauls and major maintenance events.
Open Reference →Material & Capacity Coordination
Aligning material availability with production and supplier capacity constraints.
Open Reference →EXECUTION, EXCEPTIONS & GOVERNANCE
Material Availability Planning
Monitoring whether required materials will be available when operations need them.
Open Reference →Material Shortage & Exception Management
Prioritizing shortages, identifying causes, escalating constraints and managing recovery actions.
Open Reference →Planning Rescheduling & Change Control
Managing requirement-date, quantity, priority and supply changes without losing traceability.
Open Reference →Planning Parameters & Master Data
Governance of lead time, lot size, safety stock, reorder levels, planning method and other parameters.
Open Reference →MRP Exception Messages
Interpreting expedite, defer, cancel, shortage and rescheduling signals.
Open Reference →Material Planning KPIs
Measures for availability, shortages, plan adherence, forecast quality, inventory and planning cycle performance.
Open Reference →Material Planning MIS & Dashboard
A practical dashboard for requirements, shortages, open supply, critical materials and planning performance.
Open Reference →Material Planning in Excel
Practical spreadsheet structures for consumption, requirements, lead time, stock, open orders and replenishment.
Open Reference →Material Planning in ERP
How planning parameters, MRP runs, requirements, receipts and exceptions are represented in ERP systems.
Open Reference →Planning Data Quality
Controlling item, BOM, UOM, lead-time, supplier and inventory data that drives planning accuracy.
Open Reference →Material Planning Governance & Review
Planning meetings, exception review, parameter review, ownership and continuous improvement.
