Self-coordinating buses improve service
The main challenge for an urban bus system is to maintain constant headways between successive buses. Most bus systems try to adhere to a schedule, but the natural dynamics of the system tend to collapse headways so that buses travel in bunches. We have devised a method of coordinating buses that abandons the idea of a target schedule or even any target headway and instead allows equal headways to emerge spontaneously. Read More

Multi-Criteria Analysis in Sustainability Assessment
The concept of sustainability development is still arguable. However, the major idea was established by the famous Brundtland Report characterizing it as “meeting the needs of the present without compromising the ability of future generations to meet their own needs”. Nowadays, sustainability is a multidimensional subject, involving social, economical and environmental conflicting issues and several actors. So, Multi-‐Criteria Analysis is an adequate tool for Sustainability Assessment. Read More

Economic models for horizontal collaboration
Horizontal collaboration can be seen as the sharing of resources between firms either competing or at least active on similar markets. Such collaboration initiatives are driven by the participants desire to obtain economies of scale. Given that this involves at least two independent decision makers, the traditional profit maximization approach to determine the best outcome is not adequate here. Read More

Equilibrium routing under uncertainty
We review some recent developments in the modeling of traffic in congested networks in urban transport and telecommunications. The focus is on situations where link travel times are subject to random fluctuations, including how to deal with risk averse agents. We consider both atomic and non-atomic equilibrium models, and discuss a class of adaptive dynamics that provide a plausible micro-foundation for the emergence of equilibrium. Read More

Building a bridge from research to practice: Our experience at PUC creating OR-based startup companies
Operations Research (OR) deals with all class of important real world problems. In this talk we want to share our experience at creating startups to better serve our society through the use of effective OR developments in academics domains such as vehicle routing, public transport operations, workforce management, revenue management and pricing among others.

Lagrangean relaxation and different ways it can be used
Lagrangean relaxation has gone a long way since Held and Karp introduced it in their pioneering work on the TSP. It has been used effectively and widely in integer programming, for nonlinear as well as linear models. This talk will look at different ways it has been used, either by itself, or in combination with other techniques. It will show how flexible a tool it can be by presenting applications in different areas of optimization. Read More

Introduction to chance constrained optimization
Chance constrained optimization, also called probabilistic constrained optimization, is one of the main topics in stochastic optimization for dealing with random parameters in optimization problems. A chance constraint involving random parameters should hold with a prescribed probability which is in practice close to one. The use of chance constraints goes back to the late fifties. Read More

Stochastic Gradient Methods for Machine Learning
This talk provides an overview of recent advances in stochastic gradient methods for large-scale machine learning. We begin by summarizing the main convergence results for the convex and nonconvex cases, as well as computational complexity bounds. We then consider new variants of the method that reduce the variance of the search direction. We conclude with a discussion of some key issues arising in distributed computing implementations.

Opportunities and Challenges for OR in Electricity Markets
Socio economic forces, technological developments and environmental considerations have led to restructuring of the electric power systems in part of the USA and in many systems worldwide, transforming them from vertically integrated regulated monopolies to competitive market based systems. From a supply chain perspective competitive electricity markets represent, perhaps, the most challenging supply chain. Read More

Constructive learning of preferences with robust ordinal regression
The talk is devoted to preference learning in Multiple Criteria Decision Aiding. It is well known that the dominance relation established in the set of alternatives (also called actions, objects, solutions) evaluated on multiple criteria is the only objective information that comes from a formulation of a multiple criteria decision problem (ordinal classification, or ranking, or choice, with multiobjective optimization being a particular case) Read More

Challenges and opportunities for Operations Research in fresh agri-food supply chains
Over the past few decades, the global fresh agri-food supply chains have undergone major changes, in the way they compete, and operate, where the main driver of such change has been the shifting demand and consumer expectations. Today’s consumer demands a wide assortment of products of high quality, at competitive prices, available at all times; and if possible, produced locally. Read More

Matheuristics: A Primer with Applications in Transportation and Logistics
Matheuristics are heuristic algorithms made by the interoperation of metaheuristics and mathematical programming (MP) techniques. That is, we are concerned with works that are, e.g., exploiting mathematical programming techniques in (meta)heuristic frameworks or with granting to mathematical programming approaches the cross-problem robustness and constrained CPU-time effectiveness which characterize metaheuristics.

Is it necessary to incorporate uncertainty into decision models?
All decision problems have a quota of uncertainty involved. These may be, among others, in terms of market demands, production rates, transportation times, catastrophes. One question a decision maker needs to answer is how to consider these uncertainties when developing decision making models. Read More
