We consider the problem of designing truthful mechanisms for scheduling selfish tasks on a single machine or on a set of m parallel machines. The objective of every selfish task is the minimization of its completion time while the aim of the mechanism is the minimization of the sum of weighted completion times. For the model without payments, we prove that there is no \((2-\epsilon )\)-approximate deterministic truthful algorithm and no \((\frac{3}{2}-\epsilon )\)-approximate randomized…

Efficient Online Scheduling of Electric Vehicle Charging Using a Service-Price Menu

TLDR
By letting the EV users pick their most preferable menu option, the proposed algorithm achieves a near optimal total weighted charging completion time, and prevents the users from strategically misreporting their preferences, while offering a practical and implementable solution to the problem of EVs - charging station interaction.

Implementation of optimal schedules in outsourcing with identical suppliers

TLDR
This paper deals with decentralized decision-making situations in which firms outsource production orders to multiple identical suppliers and shows that for the general case there exists no anonymous mechanism that implements optimal schedules in correlated equilibrium.

On truthfulness and approximation for scheduling selfish tasks

TLDR
The notion of increasing algorithm and a simple reduction that transforms any increasing algorithm into a truthful one are introduced and it is shown that some of the classical scheduling algorithms are indeed increasing.

TLDR
An exact characterization for the algorithms that can be used to design truthful mechanisms for such load balancing problems using appropriate side payments is given, and a lower bound of 2//spl radic/3 is proved for the best approximation ratio achievable by truthful mechanism.

Worst Case Bound of an LRF Schedule for the Mean Weighted Flow-Time Problem

TLDR
The worst case behavior of a heuristic algorithm which requires time $O(n\log n)$ is investigated, and it is shown that the mean weighted flow-time obtained by the algorithm does not exceed ${{(\sqrt 2 + 1)} / 2} \cong 1.0207$ times that of an optimal schedule.

The Price of Anarchy for Minsum Related Machine Scheduling

This work addresses the classical uniformly related machine scheduling problem with minsum objective and shows that the price of anarchy in this setting is bounded from above by 2.58, and gives a lower bound of e/(e−1)≈1.
