PIMS | UCalgary Distinguished Lecture: Tamás Terlaky
Topic
Big Data Analytics and Operations Research:
The Inmate Assignment and Scheduling Problem and its Application in the PA Department of Corrections
Speakers
Details
The inmate assignment project is a highly successful prescriptive analytics project. It was conducted in close collaboration with the PA Dept. of Corrections, took five years from start to successful implementation. Our novel Inmate Assignment Decision Support System (IADSS) is designed with the main goal of simultaneously, and system-wide optimally, assigning the inmates to the correctional institutions. IADSS includes a new hierarchical multi-objective MILO model, which accurately describes the inmate assignment problem. This is the first time that OR methodologies have been used to optimize the operations, and built into the routine business practice, of a correctional system, thus it opens a rich and untouched area for the application of OR.
This project was awarded the 2017 Daniel H. Wagner Prize for Excellence in Operations Research Practice by INFORMS.

Short Course in Conjunction with Lecture:
In conjunction with the lecture on May 17, we are offering a short course on Big Data Analytics and Operations Research, to be held May 14-16, 2018. Please register for the course by contacting Melissa Wrubleski at mwrubles@ucalgary.ca no later than Friday, May 11. Full details of the course are as follows:
Date: May 14-16, 2018
Time: 9:30am-11:30am
Location: MS 371
Title: Modern convex optimization: Duality, Algorithms, Solutions and Interpretations
Scope: Duality provides optimality conditions and serve as the platform of algorithm design. First we focus on duality in linear optimization (LO) and convex conic linear optimization (CLO) problems. CLO includes LO, second order conic and semidefinite optimization problems.
Then algorithmic concepts, such as simplex algorithms and interior point (IPMs) are discussed. Initialization of the algorithms, the computational cost and efficient computation of an iterative step, and characteristics of the produced optimal solutions are discussed. As time allows available software packages, sensitivity analysis, and some applications will be discussed.
