Our team is working with software to end in person election waiting. Key people include Drs. Shijie Huang and Muer Yang and officials at the Franklin County Board of Elections, Matthew Damschroder, Fritz Scheuren, and Steven Hertzberg.

Voting is a process similar in some ways to manufacturing and other domains for applying operations research (OR). The would be voter has a task and the system aids in task completion with measureable outcomes.
 
We are planning the fall to give our discrete event simulation validated software to the world. The "IZGBS" software is designed to:
  1. Predict election lines,
  2. Generate how many machines are needed so that all can expect to wait less than X (e.g., 30) minutes with probability greater than 95% at all locations (for officials, other county leaders, and legislators).
  3. IZGBS can also allocate a fixed set of resources across multiple locations (for officials).
We are collaborating with the Franklin County Board of elections and feel that our software (which can handle check-in and booths or DREs or almost any type of tandem queue) can help to end in-person waiting times in elections. Yet, we need collaborators and constructive suggestions. IZGBS stands for Indifference Zone Generalized Binary Search because it can do everything a generalized binary search can do while allowing declarations to be wrong by a "indifference" parameter.

White Paper on Election Systems

It is easy to underestimate the complexity of voting systems. For example, here in the Columbus area, we have over 370 locations for voting and each location has potentially more than one ballot type. In some elections, certain ballots are twice as long as others. This could even happen for precincts meeting together.

Overview

We Focus on Poll Access/Efficiency/Waiting Lines

The election system is run by legislators and local officials who have several tasks and challenges.
 
Challenges include: (1) registration issues, (2) worker recruitment and training, (3) legal issues, and (4) poll access and/or waiting lines.
 
The technologies that I have helped create focus primarily on efficiency and poll access/waiting line reductions. We model the system much like a manufacturing operation with jobs to do (voting) and resources including voters, machines, poll workers, and/or booths.
