===========================================================================================================================================================================

This file contains important information about the testbed for the SPIF and CLSIF.

===========================================================================================================================================================================
===========================================================================================================================================================================
SPIF Test Instances
===========================================================================================================================================================================
The testbed contains 360 randomly generated grid networks. The text files inside the folder "Data" contain the following arc attributes:

	Tail: 	Tail node of the arc
	Head:	Head node of the arc
	Cost: 	Arc cost
	Delay: 	Arc delay (or penalty)

The text files inside the folder "Ini" contain the following instance attributes:

	DataFile:		The name for the correspponding data file 
	Number of Arcs:		The number of arcs in the instance
	Number of Nodes:	The number of nodes in the instance 	
	Start Node:		The source node
	End Node:		The end node

===========================================================================================================================================================================
CLSIF Test Instances
===========================================================================================================================================================================
The testbed contains 40 randomly generated CLSIF instances with |T| ranging from 10 to 40.
The text files inside the folder "CLSIF Test Instances" contain the following information for each time period:

	Demand:			The demand
	Capacity:		The maximum production capacity
	Holding cost:		The unitary holding cost
	Production cost:	The unitary production cost
	Fixed cost:		The fixed cost for producing
	Shortage cost:		The unitary shortage cost
