Multi-Criteria Optimization for Fleet Size with Environmental Aspects

Chapter 13 SOLVING MULTI - CRITERIA THROUGH - FLEET ASSIGNMENT MODELS

The airline industry has been a pioneer in using operations research techniques to solve complex business problems related to the schedule planning of the airline. Given a flight schedule, an airline’s schedule planning group needs to decide the itinerary of each aircraft and each crewmember so that the total revenue minus the total operating costs is maximum and all the operational constraints...

Multi-Criteria Scheduling Optimization With Genetic Algorithms

Multi-criteria scheduling optimization with genetic algorithms is described. Scheduling optimization methodology provides the planner with a quick and efficient scheduling method and enables him/her to experiment and decide which of the suitable solutions will become the production plan. The scheduling system is composed of a business information system a database, a discrete event simulation m...

Optimal Earthmoving Fleet Size for Minimising Emissions and Cost

Traditionally, the earthmoving operations have been developed based on the minimum cost per production criterion. Nowadays, due to the negative impacts of the emissions on the environment, there is an increasing public awareness to reduce the emissions from the earthmoving operations. Different management strategies can be employed to reduce emissions, amongst other things, which can also resul...

Rail car fleet design: optimization of structure and size

We develop a model to determine the optimal structure and size of a rail car fleet at a chemical company under uncertainty in demand and travel times as well as substitution between rail car types. First, we formulate an MILP model that accounts for the substitution relations between the types and minimizes the total direct rail car cost under given rail car availability constraints and a prede...
