10. What is a supply chain?
What are the factors you need to consider tooptimize a supply chain?
- A supply chain is the sequence of organizations – their facilties, functions, and activities – that are involved in producing and delivering a product or service.
- Facilities – include factories, warehouses, distribution centers, retail outlets, and transportation vehicles.
- Functions and activities – Include forecasting, purchasing, inventory management, information management, quality assurance, scheduling, production, distribution, delivery, and customer service.
- Optimizing a supply chain1. Supply chain network design
- –locations for manufacturing facilities, suppliers, distribution centers
- -where various work packages will be performed
- 2. logistics design-transportation modes

- supplier rating is based on their performance record
- -items from a certified supplier with a gold
- -level rating do not require receiving inspections.
- -Suppliers falling below the bronze-level rating require corrective action to improve performance to an acceptable level or they will be dropped.
8. What did you learn about implementing ERP at H&B?
- Implementing ERP required a culture change
- -new business processes

6. What is an ERP system?
What are some of the functional modules?
Why is it important?
- ERP software provides a system to capture and make data available in real time to decision makers and other users in the organization.
- -integrates financial, manufacturing, and human resources data and transactions on a single computer system.
- -automates the sequential tasks business process-example: order entry, production, shipping, billing, and payment

5. What is manufacturing resource planning (MRP II)?
How does it work?
- -The process of determining short-term capacity requirements.
- -Apply MRP to determine material requirements. Then calculate the necessary resources to produce the material at each work center: Machine time and labor hours
- -Verify feasibility and adjust schedule and capacity as necessary.
- -also called “closed-loop MRP”
4. What does a material requirements planning (MRP) system do?
What arethe three inputs to an MRP system?
- It is a computer-based information system that translates master schedule requirements for end items into time-phased requirements for subassemblies, components, and raw materials.
- -MRP is designed to answer three questions:-what is needed?-how much is needed?-When is it needed?
- The three inputs are:-Master production schedule – which products are to be produced, when they are needed, and in what quantities
- .-The master production schedule covers the cumulative lead time necessary to produce the end item, from ordering of parts and raw materials to completion of final assembly.
- -Bill of materials (BOM) – a listing of all of the assemblies, subassemblies, parts and raw materials that are needed to produce one unit of the finished product.
- -The BOM a hierarchal structure, showing the quantity of each item needed to complete one unit of the next higher level of assembly.
- -Inventory records – data on the status of each item by time periods.
- -primary data includes gross requirements, scheduled receipts, expected amount on hand at the beginning of the time period, safety stock, and net requirements.-additional data incudes supplier, lead time, and lot size policy.
3. What are some of the costs of carrying inventory?
How much is thetypical annual carrying cost?
- Inventory holding costs –
- – required to finance both inventory investment (purchases) and holding costs-storage
- – rent, utilities, security-material handling
- -insurance, taxes (in some states)
- -depreciation, obsolescence, deterioration, spoilage, pilferageInventory holding costs can range from 10 to 30% of cost of sales
- – situation dependent
- Ordering costs include:-planning and placing the order
- -shipping costs
- -receiving and inspecting the order
- -moving the order to storage
- -payment of invoice
What is an inventory management system?
- A set of policies and controls that:
- -monitor levels of inventory
- -establish what levels should be maintained-decide when stock should be replenished
- -determine how large orders should be
What are the different types of inventory?
- -raw materials and purchased parts
- -work-in-progress (WIP)
- -Materials or components that have undergone change but are not yet completed.-Finished products
- – (for manufacturing firms), or merchandise available for sale (for retail firms)
- -pipeline (supply chain) inventory-materials, parts, and finished products in transit to or from the producer
- -spare parts for customer service
- -maintenance/repair/operating supplies (MRC)
9. What did you learn from the Siemens-Yazake joint venture at Ford’s supplier campus?
- Siemens-Yazake is a joint venture of a German company and a Japanesecompany, located on Ford’s supplier campus in Chicago.
- • SY supports Ford and other Tier-1 suppliers on the campusCo-location of suppliers with Ford supports JIT

- -Sell products and services to foreign companies which are investing in operations in the U.S.
- -Take advantage of more favorable taxes, investment incentives, liability laws, and environmental regulations.
- Threats:-competition in U.S. markets from imports of low cost products, parts and services
- -When key customers invest in offshore production, suppliers may need to follow to stay in the game
6. What are some of the things an operations manager can do to managethrough a downturn and successfully protect the current business .
5. Your company is considering a strategic capacity addition. Explain howyou would go about planning for the new facility.
- 1. Set a design capacity goal and a target date for launch

4. Which demand forecasting techniques would you use to support S&OP?Which demand forecasting techniques would you use to supportaggregate planning?
Aggregate demand you would use trend models is it is ran short to medium and you can get 10 30 observations. S&OP you would use casual regression model as it gets updated often and can be ran short, medium or long-term.
3. Explain the exponential smoothing forecasting technique.
- Each new forecast is based on the previous forecast plus a percentage of the difference between that forecast and the actual value of the series at that point.
- The key is to select an appropriate smoothing factor.-for relatively stable demand or for moderate growth.
2. What is the objective of aggregate planning? What can you do tostimulate demand? What can you do to adjust supply or capacity?The objective is to achieve rough equality demand and capacity over the entire planning horizon.
- To stimulate demand:
- Pricing and financing-price discounts, rebates and special financing promotions-less control over timing of demand
- Back orders-order taken in one period for delivery in another period
- New Demand-use excess capacity to provide new products or services during slack times
- To adjust supply capacity:
- Open or close plants and or change production mix
- Hire or layoff workers-possible constraints: union contracts, supply of qualified workers-additional cost of hiring and firing-many companies view workers as an asset, not a variable cost
- Overtime/slack time-increase hours or days worked to add capacity-reduce hours or days worked to reduce capacity
- Part-time workers-Depends on nature of the workInventories-
- Carrying costs
- Subcontracting-Temporary capacity

What is the "kanban" principle?
Kanban is a system of cards or signals that communicate demand and provides the authorization to move or work on parts.
The Toyota production system was established based on two important concepts.
What are they?
Explain how they work?
Jidoka- equipment stops tp prevent defects
Just in time- produce only what is needed
"Lean" is a disciplined approach to eliminating waste in all processes.
What are some examples of waste from a lean perspective?
- -time spent waiting
- -unnecessary transporting of units
- -excessive inventory
What is the objective of Sales & Operations Planning (S&OP)? Howfrequently should it be performed? What are the outputs of the S&OPprocess?
S&OP is a repetitive management process to efficiently match supply and demand, responding to continual change.It is typically performed monthly, but can be updated more frequently.The two outputs are a sales plan and a master production schedule.
