Air
Give this one a try later!
-Two times more expensive than trucking, 16 times more expensive than rail.
- Main appeal: Unmatched origin-destination speed (especially over long
distances)
-Variability is low in absolute magnitude. When variability is compared with
average delivery time, air is the least reliable mode.
- Loss and damage is low. In general, less protective packaging is required.
Center of Gravity (CoG) Method
Give this one a try later!
, Where should the facility be located given a set of points representing
source points and demand points, their volumes, and their transportation
rates?
Minimizing the sum of the volume at a point multiplied by the
transportation rate to ship to the point multiplied by the distance to the
point (i.e., total transportation cost).
Agents
Give this one a try later!
• They offer transportation services to shippers but own little/no line-haul
equipment.
• They handle numerous small shipments and consolidate them into vehicle-
load quantities.
• They also offer pickup and delivery services to shippers.
Rail
Give this one a try later!
- Long-hauler and slow mover of raw materials (e.g., coal, lumber,
chemicals)
- Low-valued manufactured products (e.g., food, paper, wood)
- Rail service exists in two legal forms: common carrier or privately owned.
• Common carrier: sells its transportation services to all shippers
• Private carriers: shipper owned with the usual intent of serving only the
owner.
Pipeline
, Give this one a try later!
- Very limited range of services and capabilities
- Most economically feasible products to transport: crude oil and refined
petroleum products.
- Product movement with pipeline is very slow (3-4 miles / hour).
- However, products are transported 24 hours/day and 7 days/week.
- Regarding the transit time: most dependable of all modes.
- Product loss and damage is low.
3. Discreteness of the Choice:

- Continuous location methods: Space is a continuum
- Discrete location methods: List of possible choices, more common
Some general observations:
