A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau
A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau
Research Collection School Of Computing and Information Systems
We consider a partially observable Markov decision process (POMDP) model for improving a taxi agent cruising decision in a congested urban city. Using real-world data provided by a large taxi company in Singapore as a guide, we derive the state transition function of the POMDP. Specifically, we model the cruising behavior of the drivers as continuous-time Markov chains. We then apply dynamic programming algorithm for finding the optimal policy of the driver agent. Using a simulation, we show that this policy is significantly better than a greedy policy in congested road network.

This paper presents our experience using the popular game FarmVille by Zynga® to teach the fundamentals of linear programming and integer programming concepts to undergraduate students in an introductory operations research course. FarmVille is a popular game within the social networking website Facebook®. A month-long contest was introduced amongst the students with the goal to be the best individual farmer by striving to reach high levels of revenue, experience, and aesthetic appeal of their own unique farm. The contest is to demonstrate the concepts of problem formulation, solution methods, multiple and competing objectives, implementation of policy, and reformulation. The students …
Delayed-Bang Approach Towards More Sustainable Critical Infrastructure Risk Management, C. Ariel Pinto, Michael K. Mcshane, Abhishek S. Pathak
Delayed-Bang Approach Towards More Sustainable Critical Infrastructure Risk Management, C. Ariel Pinto, Michael K. Mcshane, Abhishek S. Pathak
Finance Faculty Publications
This article describes the Delayed Bang Approach for determining the value of risk management alternatives in critical infrastructure security. The discussion includes (1) the need for sustainable risk management (2) the importance of time valuation in evaluating competing loss prevention and loss reduction alternatives, (3) the convergence of deterministic engineering economics, survivability analysis, and probabilistic analysis, and (4) hypothetical examples of the Delayed-Bang Approach and significance towards more sustainable risk management.
The Role Of Conflict Management On Virtual Team Performance And Satisfaction, Pilar Pazos, Anil Ustun, Rolando Delaguila
The Role Of Conflict Management On Virtual Team Performance And Satisfaction, Pilar Pazos, Anil Ustun, Rolando Delaguila
Engineering Management & Systems Engineering Faculty Publications
The role that input factors from project planning processes play on conflict emergence and conflict resolution in virtual teams is not well understood. Of particular interest for this paper is the role that factors during planning stages play in preventing interpersonal conflict, supporting conflict resolution and ultimately enhancing team outcomes in virtual team settings. This study examines the relationships among commitment to team goals, conflict management and team outcomes in virtual teams. First we provide an in depth review of relevant empirical findings. Next, we describe a study examining the relationships between three sets of variables: 1) goal commitment, 2) …
