Operating System obsolescence is widely considered an important factor when architectural choices are made during the planning phase of systems development and maintenance. In this work, we seek to understand the importance that planners actually ascribe to this attribute in practice, and ask probing questions to the managers, developers, and analysts of systems in industry in the form of a sur...

The present article is taken up with the dynamics of economic organization. In particular, it critically discusses much recent work which has asserted that economic organization—notably, the boundaries of firms, internal organization, and corporate governance—will undergo major transformative changes as a result of the emergence of the so-called “knowledge economy,” a term much fancied by busin...

Cost overrun is a chronic problem across most projects. While a significant research have been published on this topic, the understanding of the root causes and a clear direction towards improvement remained unexplored. The focus of the past research is mainly on the factors directly or indirectly associated with the project environment and their relative impacts on overall cost performance in ...

This paper describes a hybrid technical-financial procedure for allocating cost in a large data center. It is designed as a modeling tool to permit IIWHAT-IF" analyses for various configurations, levels of costing. etc. The use of modular programming, independent tables, and matrix output allows the modeler maximum flexibility in allocating cost according to changing technical and financial con...

Administration increasingly dominates the total cost of ownership of database management systems. A key task, and a very difficult one for an administrator, is to justify upgrades of CPU, memory and storage resources with quantitative predictions of the expected improvement in workload performance. We present a design and prototype implementation of a Resource Advisor that is able to answer “wh...

We present a quantitative approach for IT portfolio management. This is an approach that CMM level 1 org anizations can use to obtain a corporate wide impression of the state of their total IT portfolio, how IT costs spent today project into the budgets of tomorrow, how to assess important risks residing in an IT portfolio, and to explore what-if scenarios for future IT investments. Our quantit...

We establish a single provisioning model and process for addre...

The need for more and more dependable systems has been increased in the last decades. Strategic decisions during the design of these dependable systems require the joint control of the estimated cost and the product quality. Cost efficiency and development time became the most important factors of the software development process according to the international trends. The estimation of the cost...

O room (OR) scheduling is an important operational problem for most hospitals. In this study, we present a novel two-stage stochastic mixed-integer programming model to minimize total expected operating cost given that scheduling decisions are made before the resolution of uncertainty in surgery durations. We use this model to quantify the benefit of pooling ORs as a shared resource and to illu...

A major concern with tradable emission permits is that stochastic permit prices may reduce a firm’s incentive to invest in abatement capital or technologies relative to other policies such as a fixed emissions charge. However, under efficient permit trading, the permit price uncertainty is caused by abatement cost uncertainties which affect investment under both permit and charge policies. We d...
