Need some help on dynamic pricing questions with network problems, deterministic linear programming, etcIEOR 4601 Assignment 8

 

1. In class we considered a network problem with two resources and three itineraries, with

 

two fares per itinerary and illustrated a variety of heuristics for that problem. Here

 

we will consider an expanded model with the same three itineraries but with Fve fares

 

per itinerary. Itinerary one, consumes one unit of resource one and has Fve fares:

 

185

 

,

 

160

 

,

 

150

 

,

 

135

 

,

 

100. Itinerary two, consumes one unit of resource two and has Fve

 

fares: 130

 

,

 

115

 

,

 

95

 

,

 

80

 

,

 

75. Itinerary three, consumes one unit of each resource and has

 

Fve fares: 260

 

,

 

240

 

,

 

220

 

,

 

195

 

,

 

170. Using the single index model the incidence matrix

is given by

All vectors should be interpreted as column vectors (although for convenience we write

 

them as row vectors).
