Resource Matching Optimization

View the Video

This resource matching optimization demo combines machine learning and MIP technologies to address the fundamental problem of resource management-providing workforce resources with the right skills and capabilities, for the right job, at the right time, location, and cost.

 

Overview

Large professional services companies employ thousands of professionals making labor the industry’s highest expense. Examples of industries where professional service firms are commonly used include: Information technology outsourcing, Business process outsourcing, Accounting, Legal, Advertising, Engineering, and other specialized services.

Companies are using Machine Learning to automatically compute the matching score between resources and jobs, but the actual assignment is done manually which leads to poor demand fulfillment and low labor resource utilization, high project delivery costs and low customer satisfaction.

The integration of Machine Learning (ML) and Mixed Integer Programming (MIP) is essential to solve Resource Matching Optimization (RMO) problem effectively:

    • Machine Learning addresses the scoring of resources and jobs, but alone cannot address the complex combinatorial nature of the assignment problem
    • MIP addresses the complex combinatorial nature of the assignment problem, but alone would require a human to provide a large number of matching scores, making the approach impractical

The Problem

The goal is to find an assignment of resources to jobs that maximizes the total matching score of resources and jobs, while satisfying the requirements of jobs and the availability of resources. 

We now dive into the RMO demo itself, starting with a simple scenario. This scenario considers 62 confidential resumes from the Recruitology dataset, four non-confidential resumes, and a matching number of randomly generated jobs. The weights for the job attributes are: {Role: 45%, Technology: 35%, Domain: 20%}. For this scenario, we have disabled some resources and defined some data science jobs as high priority. Also, for another data science job we have set a minimum matching score requirement of 100%. For this scenario, we are allowed to hire a new resource for all jobs, which is the default value.

The “Assignment Quality” KPI (76.2%) measures the average matching score of all the assignments.

Typically, business conditions change frequently and an algorithm that was once efficient for solving the problem no longer works when new business conditions are considered. The new business conditions can be easily considered by adding new variables and constraints to the MIP model and then calling the Gurobi Optimizer to find a solution that recommends the best course of action. This illustrates one of the greatest advantages of using a MIP approach to solve business problems as opposed to using a heuristic.
