1 - IBM ILOG CPLEX Optimization Studio 12.2 IBM ILOG Optimization
Software Tutorial
Joshua Woodruff, Technical Account Manager, IBM, Lansing, MI,
jwoodruf@us.ibm.com
IBM ILOG CPLEX Optimization Studio supports the rapid development and
deployment of both mathematical programming and constraint programming
models, from a powerful integrated development environment using the
Optimization Programming Language (OPL), through programmatic APIs or using
3rd party modeling interfaces. In this tutorial we will explore the comprehensive
capabilities now offered in a single product offering, spanning the development,
tuning, analysis and deployment of optimization models. We will review IBM’s
machine/platform-independent keyless licensing policies, and highlight key features
of the latest release, including performance improvements in the IBM ILOG CPLEX
Optimizers and Gantt charts for reviewing and debugging scheduling models in the
CPLEX Studio IDE.

1 - Routing Assignment Problem for Ambulance Company in the Health
Society S.A. Bogotá, Colombia.

The vehicle routing plays a essential role in the efficient management of supply
chain and even more if it is the flow of people that need to be addressed in a timely
manner to save their lives. Not only is it important that response time, but also the
costs of transport are significant. Quantitative methods can provide solutions to
problems a network of transportation services for care health, in order to find a
solution feasible for operational decision.
2 - Simulation of Shrinkage Control in the Production
Process of a Quarry

fhuayta@uni.edu.pe, Wilmer Atoche
This article shows the production process of a quarry, identify the source of wastage
is calculated using computational tools and indicators shows the simulation of the
shrinkage in the process. It performs mass balance diagram, identifies the sources of
wastage, and indicators are built using a model simulating the process of the quarry.
3 - Swarm Intelligence for Pipeline Design
Martín Atlas, ITBA, Eduardo Madero 399, Buenos Aires, Argentina,
martin.atlas@gmail.com, Julio García Velasco, Diego Ros Rooney
At present, pipeline layout is performed by selecting a limited number of basic
alternatives, taking into account the case restrictions, then improved by the experts’
analysis through 2 or 3 successive iterations. This paper presents a design model
based on swarm intelligence, looking for optimize not only the construction costs
but also the operational costs along the life cycle of the pipeline. Comparative
results, reproducing a real case, are analyzed.
4 - A Methodology for Managing Operational Losses from Truck
Failures in a Mining Company

The operational performance of trucks is critical in open pit mining. We propose a
methodology based on fault trees and Bayesian networks for mitigating risks
through truck maintenance. Data collected directly from operational logs and
elicited from multidisciplinary experts are used for estimating losses and identifying
critical tasks and events. Illustrations from a copper mine are presented.

Revenue Management

1 - Heuristics for Network Revenue Management
Petr Fiala, University of Economics, W. Churchill Sq. 4, Prague 3,
13067, Czech Republic, pfiala@vse.cz
Revenue management techniques provide a powerful means of increasing revenue.
Network revenue management models attempt to maximize revenue when
customers buy bundles of multiple resources. Network revenue management can be
formulated as a stochastic dynamic programming problem whose exact solution is
computationally intractable. A number of heuristics have been proposed in the
literature. Heuristics based on extensions of the linear programming are proposed in
the paper.
2 - Alternative Booking Methodology for Airlines: Reduction in
Overbooking and Bumped Passengers
RItesh Joshi, Graduate Student, University of Florida,
3230 Sw Archer Rd, Apt # N269, Gainesville, Fl, 32608,
United States of America, ritesh.joshi@ufl.edu
The proposal is to incorporate an option into the booking system wherein a
passenger can decide at the time of booking whether or not he is willing to vary his
schedule by few hours if given some monetary reward at time of flight or before it
i.e. If he agrees and need arises then he will be paid the promised amount and his
schedule will be altered. This is a promising proposal as many travellers try to take
best price option rather that fixed schedule option.
3 - Application of Yield Management in the Saudi Corporate in the
Service Sector
Asma Bahurmoz, Professor, King Abdulaziz University, P.O. Box
9550, Jeddah, 21423, Saudi Arabia, bahurmoz@kau.edu.sa
This study is concerned with the application of yield management technique. It
explores the awareness of the technique, to what extent the prerequisite conditions
are available to facilitate its application, and what are the obstacles preventing those
organizations that are not using the technique. A sample of 300 hundred individuals
working in the Saudi service sector has been used.

1 - Patentability of Operations Research Applications
Miguel Miranda, Professor, UBA Buenos Aires University,
Engineering School, Av. Las Heras 2214, Buenos Aires, C1127AAR,
Argentina, mm@miranda-argentina.com
Patentability of inventions in connection with the different aspects of Operations
Research applications. The degree of protection under diverse patent systems is
analyzed for typical implementations involving formulations of mathematical
models, developments or use of methods for solving them, utilization or elaboration
of software and employment of devises for capturing values of parameters and for
applying the obtained levels of activities to the system or process to be optimized.
2 - Research Networks in Information Systems
Brian Dos Santos, Frazier Family Professor of CIS, University of
Louisville, College of Business, Suite #382, Louisville, KY, 40292,
United States of America, bldoss01@louisville.edu
Using publication data from 10 IS journals over a period of 10 years, we use social
network and statistical analysis to address a number of questions about author
networks in IS. We determine what makes an author successful from a social
network perspective. Does whom the author works with matter? How does the IS
network evolves over time? Are productive research clusters based on location?
3 - A Map of the Conflict in the Information Society

The volume of data in the Information Society becomes critical in situations of
conflict, increasing uncertainty and confusion -risk-. This requires swift decision
making, considering the scenarios posed by interests, rights and power at stake.
Analyzing conflict as an ontological category, we outline conceptual guides in order
to explore the actors’ interpersonal relationships, power factors involved, the
phenomenon dynamics and the settlement systems raised as options.
