Optimized Preferential Bidding Systems
نویسنده
چکیده
In a conventional PBS, each crewmember sends in his bid (i.e. preferences) without knowing the preferences of other crewmembers. He is bidding "blind". As a consequence, conflicts result: some trips are desired by (i.e. fulfill the preferences of) too many crewmembers and some are desired by no crewmembers. In the post-bid optimization process, the global optimizer attempts to reconcile conflicting bids (as represented by the final set of conflicting preferences). The optimum solution, even if it could be reliably extracted from the huge set of possibilities (using, say, LP and column generation methods), is constrained in quality by the conflicting preferences.

Optimal Bidding Strategies of GENCOs in Day-Ahead Energy and Spinning Reserve Markets Based on Hybrid GA-Heuristic Optimization Algorithm
In an electricity market, every generation company (GENCO) attempts to maximize profit according to other participants bidding behaviors and power systems operating conditions. The goal of this study is to examine the optimal bidding strategy problem for GENCOs in energy and spinning reserve markets based on a hybrid GA-heuristic optimization algorithm. The heuristic optimization algorithm used...
متن کاملUsing and comparing metaheuristic algorithms for optimizing bidding strategy viewpoint of profit maximization of generators
With the formation of the competitive electricity markets in the world, optimization of bidding strategies has become one of the main discussions in studies related to market designing. Market design is challenged by multiple objectives that need to be satisfied. The solution of those multi-objective problems is searched often over the combined strategy space, and thus requires the simultaneous...
متن کاملTeam-oriented Airline Crew Rostering for Cockpit Personnel
Airline crew scheduling is a comparably well-studied field in Operations Research. An increasing demand for higher crew satisfaction arises; especially after most relevant cost factors have been optimized to their greatest extent, mostly with secondary or little regard on quality-of-life criteria for the involved crew members. One such criterion is team-orientation. Independent from the chosen ...
متن کاملThree efficient algorithms for implementing the preferential attachment mechanism in Yule-Simon Stochastic Process
We describe how different optimized algorithms may be effective in implementing the preferential attachment mechanism in different cases. We analyze performances with respect to different values of some parameters related to the Yule process associated to the preferential attachment. We examine how performance scales with system size and provide extensive simulations to support our theoretical ...
متن کاملA Game Theoretical Approach Based Bidding Strategy Optimization for Power Producers in Power Markets with Renewable Electricity
In a competitive electricity market with substantial involvement of renewable electricity, maximizing profits by optimizing bidding strategies is crucial to different power producers including conventional power plants and renewable ones. This paper proposes a game-theoretic bidding optimization method based on bi-level programming, where power producers are at the upper level and utility compa...
