Advances in Model-Based Optimization with AMPL

Presented by: Robert Fourer
Sunday, October 16, 5:00-5:35 pm

Optimization has been fundamental to OR and Analytics for as long as there have been computers, yet we are still finding ways to make optimization software more natural to use, faster to run, and easier to integrate with application systems. This presentation offers a quick tour of ways that AMPL’s modeling framework has been enhanced to support optimization in today’s challenging applications. Topics include:

  • Expressing objectives and constraints more directly and understandably
  • Exchanging data and results more directly and efficiently, with spreadsheets and with database systems
  • Building better interfaces to applications using snapshots, callbacks, and other new features of AMPL’s APIs for popular programming languages
  • Deploying optimization in cloud environments and containers

To complement these feature advances, the presentation concludes by describing ways that AMPL is making model-based optimization more accessible, through the new Community Edition, a rewritten NEOS Server client, and free Model Colaboratory examples for teaching and learning optimization.

Quickly deploy your optimization models to the Cloud with DBOS!

Presented by: Patrice Oms and Issam Mazhoud
Tuesday, October 18, 11-11:30am

DecisionBrain Optimization Server (DBOS) is designed to help build and deploy fully scalable optimization-based applications. It enables optimization developers to focus on their models, benchmark them and allows them effortlessly to deploy those models in production in a context that will support multiple parallel runs on dedicated resources.

To achieve this, DBOS lets you encapsulate any computational module (optimization solvers, analytics modules, etc.) into so-called “Workers.” Workers can be deployed on dedicated resources (local, private, or public cloud) to ensure the best execution time. When deployed on Kubernetes, Workers may be activated on-demand to reduce cloud costs.

DBOS can be used in a stand-alone mode to run computations or it can also be integrated with existing applications to let them provide scalable and on-demand optimization capabilities and powerful monitoring capabilities.
DBOS also has a benchmarking functionality that allows you to benchmark your optimization engine across versions, different datasets, or models.
 
In this presentation, we will demonstrate how this technology can be used to:

  • Encapsulate an optimization model in a Worker
  • Deploy this Worker on a Kubernetes cluster using resources only on-demand
  • Monitor Real-time Executions
  • Benchmark models and datasets

GAMS

Turning Models Into Applications– GAMS Engine, GAMS Connect, and GAMS Transfer

Presented by: Dr. Atharv Bhosekar & Dr. Steven Dirkse
Tuesday, October 18, 8:40-9:15am

The right tools help you deploy your GAMS model and maximize the impact of your decision support application. If your model requires significant computational resources to solve, you may benefit from GAMS Engine, a powerful tool for solving GAMS models either on-prem or in the cloud. Engine acts as a broker between applications or users with GAMS models to solve and the computational resources used for this task. Central to Engine is a modern REST API that provides an interface to a scalable containerized system of services, providing API, database, queue, and a configurable number of GAMS workers.

If you are working with data stored in different formats, or you are working with an environment such as Python, Matlab, and R, you will benefit from the GAMS Connect framework and GAMS Transfer API. GAMS Connect provides unified and platform-independent data exchange between different formats (CSV and Excel). GAMS Transfer API (available in Python, Matlab, and R) makes moving data between GAMS and your computational environment fast and easy.

Optimizing Manufacturing Production Processes with MATLAB

Presented by: Sean de Wolski
Tuesday, October 18, 11:40am-12:15pm

Manufacturing processes tend to be capital intensive, operate with thin profit margins, and face continued pressure to minimize environmental impact and waste.  Process modeling tools are critical for analyzing and designing efficient processes.  In this tutorial, we will discuss how you can optimize manufacturing production processes with MATLAB, across industry applications such as semiconductor manufacturing, pharmaceutical manufacturing, and chemical blending.  Using a manufacturing process example, we will see how to assemble discrete-event simulation models.  With a model of sufficient fidelity assembled, we will explore what-if scenarios, and then answer “how many?” or “how much?” type questions with a global optimization method to maximize throughput or minimize cost.

Monday, October 17, 8-8:35am

The renewed enthusiasm for artificial intelligence (A.I.), and more particularly for techniques based on deep learning and other forms of neural networks, means that we are trying to apply these latest techniques to all problems requiring a supervised or unsupervised form of learning. But this unprecedented wave of interest often makes us forget there are other forms of machine learning that have proven themselves over time. During this presentation we will compare certain forms of machine learning with and without the contribution of neural network techniques in order to assess the importance and the nature of a possible contribution (if any). To do this, we will examine different tasks in the field of automatic language processing, namely topic modeling, automatic word disambiguation, and the development of semantic lexicons. We will also try to identify in which context an approach based on neural networks or deep learning deserves consideration.

Analytics in the Classroom: A Hands-on Approach

Presented by: Ron Freeze, Director of Enterprise Systems, Sam M. Walton College of Business 
Monday, October 17, 11-11:35am

The University of Arkansas would like to invite you to this workshop that will provide faculty participants with hands-on training in the SAS Viya analytics applications. These exercises focus on the use of data analytics and big data. The workshop will focus on connecting directly from SAS Viya to the Dillards data set that resides on the Teradata Intelliflex platform at the University of Arkansas. The data set used is updated weekly by Dillards and allows predictive analytics along with machine learning (and other analytic techniques) to be tested and validated in real time during the semester.   All materials and resources demonstrated at the workshop are available free of charge to the participants and the students in their courses.
