Answer:
- Plant/Warehouse location: economic factors dominate
Retail location: Revenue generated - cost dominates
Service operations (hospital, charity collection center, maintenance facility):
accessibility to
the site dominates
Q: 2. Number of Facilities
Answer:
- Single facility location: avoids the need to consider competitive

Q: 3. Discreteness of the Choice
Answer:
- Continuous location methods: Space is a continuum
Discrete location methods: List of possible choices, more common
Q: 4. Degree of Data Aggregation
Answer:
- Using aggregate data may be necessary but it limits
accuracy.
Little aggregation is better for retail location, intracity location, and making final
plant and
warehouse site selection
Q: 5. Time Horizon
Answer:
- Static horizon: Covers single period
Dynamic horizon: Covers multiple periods

Q: Center of Gravity (CoG) Method Where should the facility be located given a
set of points representing source points and demand points, their volumes, and
their transportation rates?
Answer:
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).
Q: Steps of CoG Method
Answer:
Notation: TC: total transportation cost
Vi : volume (demand or supply) at point i
Ri : transportation rate per unit volume to point i
di : distance to point i from the facility to be located
Xi : horizontal coordinate of source or demand point
Yi : vertical coordinate of source or demand point
X^-,Y^- : coordinates of the located facility
