Incremental airline schedule design
We consider the problem of integrating flight schedule design and fleet assignment decisions at airlines. The flight schedule design problem involves selecting and scheduling the set of flight legs that an airline will include in its service network. Fleet assignment involves assigning a particular …

Airline fleet assignment and schedule design : integrated models and algorithms
In scheduled passenger air transportation, airline profitability is critically influenced by the airline's ability to construct flight schedules containing flights at desirable times in profitable markets. In this dissertation, we study two elements of the schedule generation process, namely, …

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling
… to airline operations planning, which includes schedule design, fleet assignment, aircraft routing, and crew scheduling. The initial problem addressed by airlines is that of schedule design, whereby a set of flights having specific origin and destination cities as well as departure and arrival …

Integrated optimization model for airline schedule design : profit maximization and issues of access for small markets
… process of the airlines with respect to the schedules that they fly. The MIT Airline Scheduling Module is an incremental optimization tool to determine schedule changes from one time step to another that best meets demand using available resources. The optimization model combines an …

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.
… restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels …

Irrigation Water Pricing: Technology Adoption, Welfare, and Political Economy
… and can organize to affect the outcome of water schedule design in their favor; the exception being the inflated marginal cost tariff, which is lobby-independent. In terms of expected welfare, the two-part tariff is preferable to the nonlinear pricing scheme or the inflated marginal cost tariff.

CONTAINER TRANSPORTATION NETWORK MODELING AND OPTIMIZATION
… sailing speed optimization, ship route schedule design, and liner shipping network design. These decision problems focus on different aspects of liner shipping services with different inputs and outputs. However, their common objective is to minimize the total cost, or, to maximize the …

A theory of interdependence within the industrial design function
… theory regarding the interdependence of product design and process design as applied to industrial organization. The frame of reference used was Everett Laitala’s consumer-to-consumer cycle which separates industrial effort on the common basis of function. The explanation of the possible …

Metrics and methods of improving airline schedule reliability
… and resources are spent by airlines developing a schedule that meets expectations of profitability and competitiveness. Most of the time, however, the reliability aspect has a minor, if any, role in such a process. In reality disruption of the schedule occurs due to unforeseen events such as …

Redesigning the Schedule in the First Grade
… in the current student instructional day. Redesigning the current elementary schedule requires a steadfast commitment from the educational leader and the teachers working in collaboration to produce a comprehensive schedule that could impact student outcomes. This is the change that we have …

Implementing a digital calendar in a portfolio management context using temporal expressions
… with short scripts or equations. Martin Fowler’s Schedule design pattern provides a model for a flexible calendar design that, with some tweaking, can meet all these requirements. Though calendars are common and prevalent, the context and, by extension, its specific use cases heavily inform the …

Robust airline schedule planning : review and development of optimization approaches
Major airlines aim to generate schedules that maximize profit potential and satisfy constraints involving flight schedule design, fleet assignment, aircraft maintenance routing and crew scheduling. Almost all aircraft and crew schedule optimization models assume that flights, aircraft, crews, and …

Analysing the Network & Schedule Performance of Airlines and Developing a Passenger-Centric Commercial Methodology for Air Services
… benchmark the perceived quality of the airline schedule. However, these are open to criticism in the sense that they solely use the airline’s schedules as the input for the quality computation rather than the consumer’s perspective. Injecting dynamic consumer preference metrics on top of the …

Examining the effects of scheduled course time on mathematics achievement in high school students.
This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I …

Airline scheduling and air traffic control : incorporating uncertainty and passenger and airline preferences
… part of the thesis focuses on building aircraft schedules that are robust against delays. We develop a robust optimization approach for building aircraft routes. The goal is to mitigate propagated delays, which are defined as the delays caused by the late arrival of aircraft from earlier flights …
