JMP-SAS
Risk Visualization: Shining a Light on Uncertainty
Sam Savage and Jeff Perkinson.
Technology has changed our perception of risk and uncertainty as profoundly as the light bulb changed our perception of darkness. Technology doesn’t eliminate risk and uncertainty, but can be used effectively to illuminate them.

Probabilities, statistics, distributions and risks are typically described with numbers and obscured by complex formulas. They can also be seen as shapes. Risk visualization is the software-enabled approach of transforming risks into animated shapes. This methodology encourages its users to visually play with and explore risk mitigation design. Risk visualization maps the most probable paths to success, thereby enabling innovation and optimization.

 

Microsoft
Microsoft Solver Foundation
Microsoft Solver Foundation is a pure, managed code runtime for mathematical programming, modeling, and optimization. Microsoft Solver Foundation provides solvers and services to a broad community of users: from Excel users and analysts to programmers working on business critical scheduling, configuration, risk management and planning solutions. It provides services for model validation, parallel solving and workload scheduling, model interchange, and declarative data binding via LINQ and other NETFx technologies. As an open framework designed for third party extensibility, it exposes facilities for users to plug-in their own solvers while still leveraging all of the modeling services and capabilities of Microsoft Solver Foundation.

 

12:00pm-3:00pm Workshops
AIMMS-Paragon Decision Technology
Bringing the Power of OR Further than Your Desktop
Ming Fang and Peter Niewesteeg
In many situations, an optimization model doesn’t get much further than the desktop of the developer. As a result, a lot of the potential benefits are lost. In this workshop, we will show how AIMMS can help you to get more value out of your OR model.

In the first part of this demo we will focus on building an optimization model using AIMMS, as a good model is the first step of bringing OR further. However, in order to communicate the model and its results, an advanced GUI is needed. That is the reason why we will also demonstrate the capabilities that AIMMS has for building a graphical user interface. This includes objects like Pivot table, Network object, bar chart, pie chart, line chart and Gantt chart. So you can build a complete end-user application.

In the second part of this demo, we will focus on the ability and deploy optimization-based models further into the organization (or your customer’s organization) so these models can really create the benefits intended and become a powerful tool or driver for business decisions made every day by (non-OR) employees. We will do this by using examples from customers. Join us to learn how to bring OR from your desktop to the rest of your organization (no AIMMS experience is needed). www.aimms.com/workshops

 

Dynadec
The Hybrid Optimization System Comet
This tutorial is an in-depth introduction to Comet, a hybrid optimization system combining mathematical programming, constraint programming and constraint-based local search. The tutorial will review the underlying technologies and illustrate how they can be used to solve industrial problems in transportation, manufacturing, rostering, resource allocation and disaster management. The tutorial will also discuss how these technologies can be integrated to solve complex applications. No expertise in Comet is necessary.

 

FICO
Fast Track Optimization Modeling using Xpress-MP
This workshop will provide participants with insight into new modeling and optimization techniques; and first-hand accounts from leading business practitioners on how they are currently using optimization to solve practical problems. The workshop will be divided into two sessions. Modeling experts from FICO will present the first session, which will be technical in nature, touching on novel ways of modeling existing business problems using linear, mixed integer and quadratic programming techniques. Xpress-MP users will present the second session, which will focus on business applications of Xpress-MP, including demonstrations of how to use Xpress-MP to optimize business processes and make smarter decisions.

You’ll come away with a new enthusiasm for what you can do, and a free trial CD of software tools to do it!

 

Maximal Software, Inc.
Optimization Modeling with MPL: Integrating Optimization in Real-World Business Applications
The workshop focuses on optimization modeling and how to embed optimization models into end-user applications. It is designed to teach the participants how to develop their own optimization models, connecting them to data sources, and solve the models using state-of-the-art, industrial strength solvers. The speakers will take you through all the steps of implementing O.R. projects using optimization software tools from Maximal Software, IBM-ILOG and GUROBI. Participants will leave with an excellent overview of optimization modeling and a good working knowledge of how to successfully build optimization applications.

At the end of the workshop, we will also go over some of the major changes that happened in the optimization field during 2008 and what impact they are likely to have in the future, as well as introducing several new special programs by Maximal Software; where we are now, among other things, giving away development copies of our MPL software.
