SCM 300 Final Exam
Basic Characteristics of Lean Manufacturing
(JIT): low inventory and high efficiency. Strives to meet consumer demand and desires but with minimal inventory levels and minimal supply chain waste. Production philosophy that strives to meet consumer demand but with minimal inventory levels and minimal SC waste. (Also known as Just-in-Time (JIT) and/or the Toyota Production system (TPS)). Quality at the source, high performance quality, poka-yoke, atomization, close supplier ties, etc.
Vendor Managed Inventory
(Vendor Managed Inventory) Inventory planning and replenishment system where supplier(vendor) accepts negotiated responsibilities that typically include monitoring and restocking. Value to retailer: fewer responsibilities, decrease cost. Value to vendor: better understanding of demand rates, fewer retailer errors, responsive..
How can supply chains be more sustainable?
-Procurement: Purchasing better, fewer, and safer material. -Logistics: reduce fuel consumption, -Manufacturing and Operations, Facilities: energy consumption, reduce emissions, -Reverse Logistics: Looking both up and down the SC -SC sustainability catalysts: Large, powerful companies can be catalysts and influence thousands of suppliers. -Rethink design: lean manufacturing -Sustainability Accounting: help find areas of cost related to unsustainable business practices. -Develop Sustainability Metrics (Walmart sustainability index) -Life Cycle Analysis (cradle to cradle and cradle to grave)

What's the difference between centered curves and un-centered curves?
A centered curve means that the majority of the curve falls in the boundaries of the defect free zone. Vice versa, a off-centered curve means that the majority of it is not within boundary of the defect free zone (could be left of right). In simple words, is it on target?
Vertical Integration

Describe: Major Cargo Classifications. Examples
Bulk: which is free flowing cargo stored loose and is usually loaded by shovel. (EX: coal, rice)- usually pumped, scooped, shoveled, etc.) Break Bulk: which is general or packaged cargo often containerized, Cargo that is packaged and/or secured on a pallet. Neo-Bulk: typically, large items that don't quite fit into either the bulk or break bulk categories. (Ex. Vehicles, logs, and livestock)
Briefly describe the basics of some of the ERP support systems

Maximum time allowed for work on one unit at each station. This dictates the total time it takes for one unit to come off assembly line. CT helps us determine our max capacity.
Intermodal
One container entire trip, when cargo is moved from one vehicle or vessel to another vehicle or vessel without directly handling the cargo.
Bottleneck
One station taking more time required than the rest of the stations and creating a back up in unfinished goods. If you have too many bottlenecks or even just one bottleneck it increases your total task time, and thus diminishing your max capacity. (You're only as strong as your weakest link)

(ex. oil)
Bullwhip Effect
SC phenomenon where fairly stable demand results in a proliferation in the amount of inventory that is carried as one travels upstream the SC. Very high and very low supply levels despite fairly constant demand levels.
Downstream
Stage in the production process involves processing the materials collected during the upstream stage into a finished product
Upstream
Stage of the production process involves searching for and extracting raw materials.
Offshoring
Strategy where a company moves manufacturing out of its "home" country to another country.

Reneging
When people enter the line but then leave because of the wait time
Balking
When people fail to enter the line because of the number of people already present (people don't even enter the line- decide its not worth the wait)
What does it mean if AHC < AOC? Increase or decrease Q?
You should increase quantity, because it below the EOQ.
What does it mean if AHC > AOC? Increase or decrease Q?
You would lower quantity, because it is above the EOQ.
Near Sourcing
a type of offshoring or offshoring and outsourcing where the location of the manufacturing facility is relatively close to the location of the consumer; typically refers to a shift in strategy where a company used to manufacture goods very far away from the home market, but then shifts to manufacturing in a country that is much closer to the home market.
