Extreme programming (XP) calls for intense participation by users to ensure that systems are developed to meet current needs, yet be flexible enough to adapt to future needs [Beck, 2000]. In XP projects, it is crucial for developers to align their efforts with those of the users that are...

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 consider advertising problems under an IT capacity constraint encountered by electronic retailers in a duopolistic setting. While there is a considerable amount of literature on advertising games between firms, introducing an IT capacity constraint fundamentally changes this problem. In the...

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...

The world seems to be getting more dangerous: terrorists; fraudulent corporations; money laundering; hurricanes; pandemics. Governments and organizations respond with a flurry of new controls. In some cases these are centrally mandated (e.g. Sarbanes Oxley). In others, organizations struggle to...

Recently blockchain has emerged as a distributed ledger based platform, which has gained repute in the domain of cryptocurrency technology. The non-modifiable aspect of blockchain makes it a candidate to store the absolute truth that cannot be disputed. Additionally the distributed nature of...

With the proliferation of new innovative technologies, electronic gadgets like smartphones loaded with sophisticated user friendly apps are getting popularity among large proportion of phone users. As a result, advertisers are using apps as a medium of communication to showcase their products...

We present a model to determine the optimal point for maintaining a software application. We also address the question: given that a maintenance project has been initiated, should maintenance effort continue till the project is completed? Most previous literature has implicitly assumed that it...

Emerging technologies such as drone delivery services enable retailers to cost-effectively offer unprecedented delivery speed and adaptable delivery lead times using dedicated aerial vehicles for individual orders. A natural and important question arises: What is the impact of a drone delivery...
