2.List items in descending order based on annual dollar usage; 3. Calculate cumulative annual dollar volume; 4. Classify items into groups. Justifying smaller order quantities ? JIT or “Lean Systems”would recommend reducing order quantities to the lowest practical levels ? Benefits from reducing Q’s : ? Improved customer responsiveness (inventory = Lead time) ? Reduced Cycle Inventory ? Reduced raw materials and purchased components ? Justifying smaller EOQ’s : ? Reduce Q’s by reducing setup time (S) . Inventory record accuracy 2 Methods are available for checking inventory record accuracy: 1. Periodic counting; 2. Cycle counting. Periodic counting (physical counting) – disadvantages: The job is often rushed and is done by employees not trained for checking inventory. Inventory record errors are increased rather than reduced. Cycle counting – counting inventory throughout the year: Series of mini-physical inventories done daily. A-items are counted most frequently. H 2DS Q ?

Types of aggregate plans Level Aggregate Plans – planning approach > same quantity each time period. Inventory & backorders used to absorb demand fluctuations: ? Maintains a constant workforce ? Sets capacity to accommodate average demand ? Often used for make-to-stock products like appliances ? Disadvantage - builds inventory and/or uses back orders Chase Aggregate Plans – planning approach > varies production to meet demand: ? Produces exactly what is needed each period ? Sets labor/equipment capacity to satisfy period demands ? Disadvantage - constantly changing short term capacity Hybrid Aggregate Plans - options using various combinations of inventory, backorders, and capacity to achieve cost and customer service objectives: ? Uses a combination of options ? Options should be limited to facilitate execution ? May use a level workforce with overtime & temps ? May allow inventory buildup and some backordering ? May use short term sourcing Aggregate Planning Options Demand based options – respond to demand fluctuations through inventory / backorders, of by shifting demand pattern ? Reactive : uses finished goods inventories and backorders for fluctuations
