Using Real-Time Decision Tools to Improve Distributed Decision-Making Capabilities in High-Magnitude Crisis Situations*

Abstract

Multi-organizational collaborative decision making in high-magnitude crisis situations requires real-time information sharing and dynamic modeling for effective response. Information technology (IT) based decision support tools can play a key role in facilitating such effective response. We explore one promising class of decision support tools based on machine learning, known as support vector machines (SVM), which have the capability to dynamically model and analyze decision processes. To examine this capability, we use a case study with a design science approach to evaluate improved decisionmaking effectiveness of an SVM algorithm in an agent-based simulation experimental environment. Testing and evaluation of real-time decision support tools in simulated environments provides an opportunity to assess their value under various dynamic conditions. Decision making in high-magnitude crisis situations involves multiple different patterns of behavior, requiring the development, application, and evaluation of different models. Therefore, we employ a multistage linear support vector machine (MLSVM) algorithm that permits partitioning decision maker response into behavioral subsets, which can then individually model and examine their diverse patterns of response behavior. The results of our case study indicate that our MLSVM is clearly superior to both

“…Another framework for transportation planning was proposed by Barbarosoğlu and Arda ( 2004 ) wherein a two-stage programming model was introduced to disperse medical aid at the time of disaster. To improve decision making during large scale disasters, Moskowitz et al ( 2011 ) employed machine learning tool of multistage linear support vector machine to quickly assess the response strategy, and Mendonça ( 2007 ) developed a decision support system which can be improvised based on the response to natural disasters.…”

Industrial Digitization, the Use of Real-Time Information, and Operational Agility: Digital and Information Perspectives for Supply Chain Resilience

“…First, it provides evidence that the URTI enhances operational agility and SCR. The past literature suggests that the URTI supports the development of other capabilities-e.g., analytical capability [108], customer engagement [15], decision-making capabilities [109], environmental management [110], process capability [111], and sales [8], [15]. Second, this study demonstrates the mediation role played by operational agility between the URTI and SCR, which had not been investigated by the extant literature.…”

Simulation of Crisis Management Processes as a Means of Education

“…The teaching methods are supposed to be certifi ed by the Ministry of Interior of the Czech Republic. Thanks to it, the usage of teaching facility for the preparation and training of the staffers of crisis management bodies and IRS units, as well as the members of companies and institutions crisis staffs, can be expected (GREEN and KOLESAR, 2004;MOSKOWITZ et al, 2011).…”
