Designing multi-attribute auctions for engineering services procurement in new product development in the automotive context
2010
Abstract In recent years, use of multi-attribute auctions has been consolidating as a powerful mechanism in procurement settings where multiple drivers affect the transaction outcome. This paper provides a project management approach for multi-attribute auction design for standardized engineering services procurement in the context of new product development in automotive industry. Two variables are taken into account in the bidding process: price and duration of the given engineering activity. From a theoretical viewpoint, we fully determine optimal suppliers’ bidding strategies and expected outcomes, i.e. score/utility, price and duration, for the buyer under both first score sealed bid a…
IncentMe: Effective Mechanism Design to Stimulate Crowdsensing Participants with Uncertain Mobility
2018
Mobile crowdsensing harnesses the sensing power of modern smartphones to collect and analyze data beyond the scale of what was previously possible with traditional sensor networks. Given the participatory nature of mobile crowdsensing, it is imperative to incentivize mobile users to provide sensing services in a timely and reliable manner. Most importantly, given sensed information is often valid for a limited period of time, the capability of smartphone users to execute sensing tasks largely depends on their mobility pattern, which is often uncertain. For this reason, in this paper, we propose IncentMe, a framework that solves this core issue by leveraging game-theoretical reverse auction …
A breath of fresh air: french books in the Catalogues of the 18th century of the bookshop Mallén of Valencia
2013
Los Catálogos de libros constituyen junto a las subastas de libros y los inventarios de bibliotecas las fuentes más importantes para el estudio del mundo del libro durante el siglo XVIII. A través del estudio de los libros franceses procedentes de los Catálogos de la familia Mallén de libreros de Valencia se pretende conocer mejor los autores y obras que circularon en la ciudad, además de los circuitos, proveedores y clientes de tal comercio. Un negocio que contribuyó a modernizar las estructuras culturales y políticas del momento. The Catalogues of books constitute close to the auctions of books and the inventories of libraries the most important sources for the study of the world of the b…
Wine - investment: a profitable alternative investment or a simple long term pleasure?
2014
International audience; The purpose of this work is twofold: - to make a first historic analysis of performance through an investment in wine by comparing its performance with those that would have been possible to obtain at the same time by providing financial term investments; - to introduce the regional diversity of performance by considering the situation in the three selected geographic areas.
A Binary Particle Swarm Optimization Algorithm for a Double Auction Market
2007
In this paper, we shall show the design of a multi-unit double auction (MDA) market. It should be enough robust, flexible and sufficiently efficient in facilitating exchanges. In a MDA market, sellers and buyers submit respectively asks and bids. A trade is made if a buyers bid exceeds a sellers ask. A sellers ask may match several buyers bids and a buyers bid may satisfy several sellers asks. The trading rule of a market defines the organization, information exchange process, trading procedure and clearance rules of the market. The mechanism is announced before the opening of the market so that every agent knows how the market will operate in advance. These autonomous agents pursue their o…
Impact of Risk Aversion on Bidder's Optimal Strategy in Takeover Contests
2008
We consider a takeover setting in which bidders are risk averse and study aversion's consequences on their strategy. We found that when bidders are risk averse, under some conditions, their overbidding depends on the size of toeholds they hold. We show that there is a threshold under that a bidder doesn't overbid into the takeover process and becomes aggressive above that treshold. However, if the overbidding increases in toeholds size, it decreases in valuation. Without toeholds, takeovers's results are similar if bidders are averse or neutral risk.
Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations
2017
In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…
Functional food characteristics in organic food products—the perspectives of Italian consumers on organic eggs enriched with omega-3 polyunsaturated …
2022
Abstract Innovation in organic food products plays an important role in further developing its competitiveness in the market and meeting the emerging consumers’ needs. However, few studies have analysed consumers’ points of view of innovations on organic food, limited to the change in the natural food composition or the enrichment of the nutritional contents of the product. This study, using experimental auctions, aims to overcome this gap by enriching the knowledge on organic consumers’ preference for organic food with functional characteristics. Specifically, this study analyses the willingness to pay (WTP) of 110 Italian consumers for organic eggs enriched with omega-3 polyunsaturated fa…
Smart Auctions for Autonomic Ambient Intelligence Systems
2020
The main goal of Ambient Intelligence (AmI) is to support users in their daily activities by satisfying and anticipating their needs. To achieve such goal, AmI systems rely on physical infrastructures made of heterogenous sensing devices which interact in order to exchange information and perform monitoring tasks. In such a scenario, a full achievement of AmI vision would also require the capability of the system to autonomously check the status of the infrastructure and supervise its maintenance. To this aim, in this paper, we extend some previous works in order to allow the self-management of AmI devices enabling them to directly interact with maintenance service providers. In particular,…
A wholesale electricity market framework with bilateral trading
2011
An agent-based simulation model for a hybrid power market structure is presented. A bilateral transaction mechanism is combined with a uniform-pricing auction settlement in order to isolate the impact of medium-term bilateral contracts on market power and spot prices in a competitive wholesale market setting. First we describe the negotiation method for bilateral trading of energy and then introduce a new approach for bidding in the DA market based on the load duration curve. We find that, despite the conventional concerns, the foreclosure ef- fect produced by the bilateral agreement between a generation and a retail business will not necessarily lead to higher prices, and will be manifeste…
