Negotiating over Bundles and Prices Using Aggregate Knowledge
Combining two or more items and selling them as one good, a practice called
bundling, can be a very effective strategy for reducing the costs of producing,
marketing, and selling goods. In this paper, we consider a form of multi-issue
negotiation where a shop negotiates both the contents and the price of bundles
of goods with his customers. We present some key insights about, as well as a
technique for, locating mutually beneficial alternatives to the bundle
currently under negotiation. The essence of our approach lies in combining
historical sales data, condensed into aggregate knowledge, with current data
about the ongoing negotiation process, to exploit these insights. In
particular, when negotiating a given bundle of goods with a customer, the shop
analyzes the sequence of the customer's offers to determine the progress in the
negotiation process. In addition, it uses aggregate knowledge concerning
customers' valuations of goods in general. We show how the shop can use these
two sources of data to locate promising alternatives to the current bundle.
When the current negotiation's progress slows down, the shop may suggest the
most promising of those alternatives and, depending on the customer's response,
continue negotiating about the alternative bundle, or propose another
alternative. Extensive computer simulation experiments show that our approach
increases the speed with which deals are reached, as well as the number and
quality of the deals reached, as compared to a benchmark. In addition, we show
that the performance of our system is robust to a variety of changes in the
negotiation strategies employed by the customers.Comment: 15 pages, 7 eps figures, Springer llncs documentclass. Extended

Innovative approaches to water security:ICTs as platforms for systemic online negotiation
This paper presents the initial outcomes of the research project âInnovative approaches to water security using ICTs for systemic online negotiationsâ carried out between the department of Systems at the OU, UNESCO PC-CP program and UNESCO-IHE Institute of water education. It explores how water conflicts could be managed - by being prevented through integrated water management and - through better communication amongst water stakeholders and more systemic analysis of water problems at stake

Multiobjective optimization as a decision aid for managing build-to-order supply chains
This paper provides an overview of multiobjective optimization (MOO) as a decision aid in
build-to-order supply chains (BTO-SC). The main features of BTO-SCs are discussed along
with capabilities of MOO to enhance decision making at different points along the chain.
Key decision points across a typical BTO-SC are identified and potential applications of
MOO are discussed. A sample application is presented and future avenues for further research
highlighted
Online Learning of Aggregate Knowledge about Non-linear Preferences Applied to Negotiating Prices and Bundles
In this paper, we consider a form of multi-issue negotiation where a shop
negotiates both the contents and the price of bundles of goods with his
customers. We present some key insights about, as well as a procedure for,
locating mutually beneficial alternatives to the bundle currently under
negotiation. The essence of our approach lies in combining aggregate
(anonymous) knowledge of customer preferences with current data about the
ongoing negotiation process. The developed procedure either works with already
obtained aggregate knowledge or, in the absence of such knowledge, learns the
relevant information online. We conduct computer experiments with simulated
customers that have_nonlinear_ preferences. We show how, for various types of
customers, with distinct negotiation heuristics, our procedure (with and
without the necessary aggregate knowledge) increases the speed with which deals
are reached, as well as the number and the Pareto efficiency of the deals
reached compared to a benchmark.Comment: 10 pages, 5 eps figures, ACM Proceedings documentclass, Published in

MACS: Multi-agent COTR system for Defense Contracting
The field of intelligent multi-agent systems has expanded rapidly in the recent past. Multi-agent architectures and systems are being investigated and continue to develop. To date, little has been accomplished in applying multi-agent systems to the defense acquisition domain. This paper describes the design, development, and related considerations of a multi-agent system in the area of procurement and contracting for the defense acquisition community

Centralized versus market-based approaches to mobile task allocation problem: State-of-the-art
Centralized approach has been adopted for finding solutions to resource allocation problems (RAPs) in many real-life applications. On the other hand, market-based approach has been proposed as an alternative to solve the problem due to recent advancement in ICT technologies. In spite of the existence of some efforts to review the pros and cons of each approach in RAPs, the studies cannot be directly applied to specific problem domains like mobile task allocation problem which is characterised with high level of uncertainty on the availability of resources (workers). This paper aims to review existing studies on task allocation problems(TAPs) focusing on those two approaches and their comparison and identify major issues that need to be resolved for comparing the two approaches in mobile task allocation problems. Mobile Task Allocation Problem (MTAP) is defined and its problematic structures are explained in relation with task allocation to mobile workers. Solutions produced by each approach to some applications and variations of MTAP are also discussed and compared. Finally, some future research directions are identified in order to compare both approaches in function of uncertainty emerging from the mobile nature of the MTAP
Consensus-based approach to peer-to-peer electricity markets with product differentiation
With the sustained deployment of distributed generation capacities and the
more proactive role of consumers, power systems and their operation are
drifting away from a conventional top-down hierarchical structure. Electricity
market structures, however, have not yet embraced that evolution. Respecting
the high-dimensional, distributed and dynamic nature of modern power systems
would translate to designing peer-to-peer markets or, at least, to using such
an underlying decentralized structure to enable a bottom-up approach to future
electricity markets. A peer-to-peer market structure based on a Multi-Bilateral
Economic Dispatch (MBED) formulation is introduced, allowing for
multi-bilateral trading with product differentiation, for instance based on
consumer preferences. A Relaxed Consensus+Innovation (RCI) approach is
described to solve the MBED in fully decentralized manner. A set of realistic
case studies and their analysis allow us showing that such peer-to-peer market
structures can effectively yield market outcomes that are different from
centralized market structures and optimal in terms of respecting consumers
preferences while maximizing social welfare. Additionally, the RCI solving
approach allows for a fully decentralized market clearing which converges with
a negligible optimality gap, with a limited amount of information being shared.Comment: Accepted for publication in IEEE Transactions on Power System
