Strategic stock

Additional inventory beyond cycle and safety stock generally used for very specific purpose or future event and for defined period. Hedge current fluctuations Take advantage of price discount Protect against short term disruptive supply event Take advantage of opportunity Life cycle changes- seasonal, new product launch, etc.

Chase Production Strategy

Adjust capacity to match demand. Firm hires and lays off workers to match finished output to demand. Finished goods inventory remains constant. Good for market-to-order companies. ex.) construction company- union employees sent back and recalled accordingly

Customer Survey

Advantage- direct method of assessing info from primary source, simple to administer and comprehend, no bias Disadvantage- poorly formed questions lead to unreliable data, customer may not answer, costly and time consuming

Planning Processes

Aggregate production planning (APP) Master Production Scheduling (MPS) Material Requirement Planning (MRP) Distribution Requirement Planning (DRP) Capacity Planning

Strategic Sourcing

Approach to supply chain management that formalizes way info gathered and used such that organization can leverage its consolidated purchase power to find best possible values in market-place. Disciplined, systematic process to reduce total cost of externally purchased materials, equipment and service while maintaining/improving levels of quality, service, and tech.

Co-Managed Inventory (CMI)

Arrangement where specific quantity of item stored at buyer's location. Once used item replaced by supplier with full knowledge and approval of buyer. Buyer provides ordering system access to supplier and supplier has responsibility for mangement and replenishment process.

Multiple Linear Regression

Attempts to model relationship between 2 or more independent variables and dependent variable (demand) by fitting linear equation to observed data

Simple linear regression

Attempts to model relationship between single independent variable and dependent variable (demand) by fitting linear equation to observed data. Describes relationship between independent and dependent variable as straight line.

Inventory Carrying Costs (ICC)

Average Inventory Value ($) x Carrying Cost (%) Ex.) Order delivery = 10,000 tons/month SS = 2,000 tons Purchase price = $50/ton Inventory expense = 20% Cycle stock + SS = Total Avg Inventory 5,000 + 2,000 = 7,000 Avg Inventory Cost = 7,000 x $50 =$350,000 ICC = $350,000 x 20% = 70,000

Cycle stock (CS)

Average inventory for periodic fixed order quantity or order quantity CS = Q / 2 Ex.) Q = 10,000 tons per year CS = 10,000 / 2 = 5,000 tons

Finding Economic Order Quantity?
