We study the problem of a cloud service provider (e.g., Amazon Web services) selling cloud services to a buyer (e.g., Uber) under congestion. Cloud congestion has received significant attention in recent years, leading to reduced service quality and a potential loss of customers (e.g., riders...

Refurbishing of used products is increasingly being recognized as a value recovery strategy in sustainable operations. Both manufacturers and retailers engage in refurbishing. Manufacturers, to some extent, can deter other players from refurbishing through various means such as product design,...

We develop an optimal control model to maximize the net value provided by a software system over its useful life. The model determines the initial number of features in the system, the level of dynamic enhancement effort, and the lifetime of the system. The various factors affecting these...

Software patch management has now assumed tremendous significance and it directly affects the customer opinion about the quality and security of the released product. Hence, software vendors are forced to put in substantial amount of effort for servicing released products, and maintain a fairly...

As the competition in the software development business grows fiercer, the features provided in the software become more and more important. With the growing popularity of open source software and the advent of new software delivery models, such as software-as-a-service, the traditional software...

We develop an optimal control model to maximize the net value provided by a software system over its useful life. The model determines the initial number of features in the system, the level of dynamic enhancement effort, and the lifetime of the system. The various factors affecting these...

We develop variations of the M|G|1 queue to model the process of software maintenance within organizations and use these models to compute the optimal allocation of resources to software maintenance. User requests are assumed to arrive following a Poisson process and a binomial distribution is...

Due to economic and physical resource constraints, it is not feasible to continually expand transportation infrastructures to adequately support the rapid growth in the usages of these infrastructures. This is especially true for traffic coordination systems where the expansion of the road...
