Format:
1. In this example data, we present the
base class (biggest class) used in the case study (155 farms, 20 collection
facilities and 5 biorefineries). 8 small-sized classes and 8 large-sized
classes are selected from the base class. There are 10 instances under each
class by by multiplying the values of cost parameters
(c^s_{il}, c^I_{i}, c^1_{fi}, c^2_{ij}, c^h_{fn} and c^b_{f})
with a random number.
2. The location values are given as lat-long coordinates. The Euclidean distance formula is
used to calculate the distances between facilities.
3. We have the following data files:
a. Location data.xlsx: Location coordinates of farms,
collection facilities and biorefineries
b. Available land.xlsx: Available land for planting
switchgrass in each farm
c. Switchgrass yield.xlsx: Amount of switchgrass yield in
each farm
d. Transportation cost.xlsx: Transportation cost of one unit
of switchgrass from farms to collection facilities and from collection
facilities to biorefineries
e. Unit production cost.xlsx: Unit production cost for
switchgrass in farm
f. Robust parameters.xlsx: Farmer group number for each
farmer
g. Other cost parameters.txt: Some other cost parameters
h. Generation of 10 random instances.txt: Random numbers for generation of
10 random instances
4. The legend for the input data format
