Browser and proxy-server caching are effective and relatively inexpensive methods of improving Web performance. Most existing research considers caching to occur independently at the browser and the proxy server. When the browser and the proxy-server cache independently, documents may get...

Software product versioning (i.e., upgrading the product after its initial release) is a widely adopted practice followed by leading software providers such as Microsoft, Oracle, and IBM. Unlike conventional durable goods, software products are relatively easy to upgrade, making upgrades a...

We study optimal policies for design reuse in a software project using a control theoretic approach. A project needs to be developed in minimum time by optimally choosing the proportion of effort allocated towards design activities. We first consider a local case, where the benefits of design...

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...

The unprecedented rate at which data is being generated has led to the growth of data markets where valuable datasets are bought and sold. A salient feature of this market is that a data-buyer (agent) is endowed with multi-dimensional private information, namely her ``ideal'' record that she...

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...
