Selected Research

Eliminating the Weakest Link Approach in Army Unit Readiness (2018)
Decision Analysis 
Authors: Natalie M. Scala & Paul L. Goethals

This study examines the United States Army’s readiness metrics, as outlined in AR-220-1, and propose an improvement in the composite metric, in order to evaluate units with greater precision, flexibility, and robustness. Our desirability function approach measures readiness based upon a set of priorities, adapting for type of mission and unit. Accurate assessments of readiness are crucial, as the level of Army readiness drives federal funding, defense policy, and deployment decisions. AAM via INFORMS Green Option

A Value Model for Asset Tracking Technology to Support Naval Sea-based Resupply (2018)
Engineering Management Journal
Authors: Natalie M. Scala & Jennifer Pazour 

Naval seabasing is a dense storage environment and requires specialized logistics to fulfill emergent requests for tailored resupply packages while at sea. We develop a value model to identify the preferred technology to track inventory assets while stored in this dense environment. Evaluated technologies include radio frequency identification, barcoding, internal positioning systems (IPS), and camera-aided technology. We conclude that IPS is the preferred asset tracking technology in the seabasing environment.

Aligning Supply Chain Transportation Strategy with Industry Characteristics: Evidence from the US-Asia Supply Thain (2015)
International Journal of Physical Distribution and Logistics Management
Authors: Ke, J. Y. F., Windle, R. J., Han, C., & Britto, R

The study evaluates how firm’s choices of transportation mode are the result of industry characteristics and supply chain strategies. The findings suggest that beyond transportation cost, logistics managers must also consider non-cost factors including the level of competition, the amount of working capital available, and the uncertainty of demand when making transportation mode decisions.
