An exact model for airline flight network optimization based on transport momentum and aircraft load factor

Transportes, 2017
The problem of airline flight network optimization can be split into subproblems such as Schedule Generation (SG) and Fleet Assignment (FA), solved in consecutive steps or in an integrated way, usually based on monetary costs and revenue forecasts.

CEMENT TRANSPORTATION LIMITED-FLEET MODELING AND ASSIGNING TO RATED DEMANDS [PDF]

Transport Problems, 2017
Transportation is an inseparable part of the supply chain, with a key role in product distribution. This role is highlighted when ratio of “the cost of transportation” to “the value of goods” such as cement is significant. Iran has recently become one of

Cooperation patterns between fleet owners for transport assignments

2015 IEEE Conference on Control Applications (CCA), 2015
We study cooperation patterns between the heavy-duty vehicle fleet owners to reduce their costs, improve their fuel efficiency, and decrease their emissions. We consider a distributed cooperation pattern in which the fleet owners can communicate directly with each other to form alliances.
