Findings

Effective optimization of labor-hours and duty distribution.

Improved proctoring quality in large-scale testing.

Open-source availability for educational institutions.

Abstract

We present the mathematical modeling for the problem of choosing rooms and proctoring crews for massive tests, together with its implementation as the open-box system RaPID-Omega. The mathematical model is a binary integer programming problem: a combination of the 0-1 Knapsack problem and the job-assignment problem. The model makes decisions according the following criteria in order of priority: minimization of labor-hours, maximization of equity in the distribution of duties and maximization of the proctoring quality. The software is a digital solution for the aforementioned problem, which is a common need in educational institutions offering large, coordinated, lower-division courses.
