The most expensive project in human history is the International Space Station (ISS); it has reached $160+ billions in total expenses. Currently, the lifespan of the ISS has been exceeded, and the spacecraft operations is projected for a minimum of 10 years. However, due to its aging technology,...
In the package delivery industry, competitive advantage is changing with the evolution of customer expectation. The United States Postal Service (USPS) started with the delivery of letters, but had to restructure its company when the mailing of letters began to decrease, while simultaneously the...
The US Air Force (USAF)’s goal is to achieve aircraft availability (AA) rates similar to those of the commercial airline industry. Improving AA rates while reducing operations and maintenance (O&M;) costs is a major challenge for the USAF. This Praxis research identifies field-level components...
An engineering change (EC) is an alteration made to a system that has beenreleased following a system design process. EC propagation is a series of ECs occurringdue to dependencies among components of a product. ECs can consume up to 50% of theoverall engineering efforts during development of a...
Uncertainty arising from immature technology is a major cause of programmatic risk. Programs continue to have poor results in terms of cost and schedule performance. This research seeks to improve program performance during the system development phase by better understanding the risks of...
Current management and technical structures of the electric power system in Togo have shown their limits. Togo continues to suffer from limited access to electric power and endemic electric power shortages resulting in the slow-down of the country’s socio-economic development. For over 43 years,...
Oil and Gas Exploration and Production (E&P;) projects routinely experience cost overruns and delays, with about 64% of new projects exceeding their budgets and almost 75% completed behind schedule partly as a result of non-optimal project designs1. Owing to the highly complex and heterogeneous...
The last thirty years have seen multiple DoD acquisition programs with significant cost and schedule overruns. This paper posits that the primary driver of schedule overruns is the difficulty of “inventing on a schedule” by undertaking risky technology development efforts within a Major Defense...
Electronic waste (e-waste) is a growing economic opportunity for informal recycling operations in developing countries, while it is a major health and environmental concern for the developed world. Currently, only 25% of gold in e- waste is recovered successfully through informal recycling...
Although the traditional intrusion detection problem has been well studied with the release of the KDD’99 and NSL-KDD datasets, recent intrusion detection has expanded to include wireless 802.11 networks and Industrial Control Systems & Supervisory Control and Data Acquisition (ICS/SCADA)...
