Network Models for Fleet Management*
Decision Sciences, 1989ABSTRACTThis paper presents network models to determine the optimal replacement policy for a fleet of vehicles over a finite planning horizon. First, a minimum cost‐flow model is developed to determine the optimal replacement schedule for a fleet of fixed size consisting of a single type of vehicle of various ages.

Analytical Models for Fleet Management
SSRN Electronic Journal, 2006This paper has been motivated by a fleet optimization problem faced by one of the leading European cargo rail companies. The company operates a fleet of more than 100,000 rail cars and annually invests significant sums of money into new cars. Because the price tag of a new car is over 50,000 euros, planning such a fleet is an important activity at the ...

Heterogeneous Fleets Distribution Models
2020In this chapter, we introduce heterogeneous fleet delivery systems which are motivated by the availability of new technological devices (i.e., robots and drones), and by the large increase of goods deliveries to consumer locations. Both the growth of e-commerce logistics and the subsequent fragmentation of distribution flows in high density populated ...

The Aeronautical Journal, 1983
Fleet planning is a complex process. Undertaking it is time consuming as, properly conducted, it involves virtually every part of the airline organisation in a series of sub-analyses all of which impact on each other in some way. Parts of the process are deeply technical but others may be purely subjective relying on the intuition or judgement of the ...

Modeling Average Maintenance Behavior of Fleet of Airplanes using Fleet-MCS
AIAA Infotech@Aerospace 2010, 2010In aircrafts, fuselage inspections are performed regularly to remove large damages that threaten the safety of the structure. Recently, structural health monitoring techniques have been developed that uses sensors and actuators to detect damages on structures paving way for progressive inspection.

There are certain standard examples from the area of combined simulation which appear repeatedly in the literature. The tanker fleet model is one of these. It appeared first in “The GASP IV Simulation Language” /1/.

Queuing Models for Estimating Aircraft Fleet Availability
IEEE Transactions on Reliability, 1977The availability of a small fleet of aircraft in a flying-base, repair-depot combination is modeled and studied. First, a deterministic flow model relates parameters of interest and represents the state-of-the art in the planning of such systems. Second, a cyclic queue model shows the effect of the principal uncertainties in operation and repair and ...

Airline Fleet Assignment with Enhanced Revenue Modeling
Operations Research, 2009The airline fleet assignment problem addresses the question of how to best assign aircraft fleet types to scheduled flight legs. This paper presents the subnetwork fleet assignment model: a model that employs composite decision variables representing the simultaneous assignment of fleet types to subnetworks of one or more flight legs.

Fleet Structures Model: A Strategic Fishing Fleet Management Policy Appraisal Model
1990The Fleet Structures Model simulates aspects of the structure and operation of a heterogeneous sea fishing fleet in order to make comparative appraisals of fisheries management strategies under varying assumptions about the behavioural environment. The model is dynamic, with predictions in yearly incremental steps which include interactions between ...
