The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order to increase the accuracy of this process, estimation models have to be revised. The Construct...

traffic events account for about 1,200,000 deaths and more than 50 million injuries annually across the world. research shows that male drivers make up the majority of those who sustain injuries in car accidents. the present research aims to compare psychological factors affecting driving-related crashes of male and female drivers. accordingly, the sample data is collected from 208 crash-involv...

The impact of operational performance on airline cost structure is empirically investigated using an aggregate, statistical cost estimation approach. Two distinct sets of operational performance metrics are developed and incorporated into the airline cost models as arguments. Results from estimating a variety of airline cost models reveal that both delay and schedule buffer are important cost d...

Data Mining is a research line that began in 1980 in order to find the knowledge that is hidden in the data that organizations are storing in a daily basis. This knowledge supports the decision-making processes in organizations. As a consequence companies of every kind have been developing data mining projects since the term appeared. However, there is no way to estimate this kind of projects. ...

This report describes young driver crashes in Alaska, compares rates and characteristics of young driver crashes with adult driver crashes, and summarizes the medical and financial outcomes of young driver crashes, for the period 1991 through 1995. Using the Mini Crash Outcome Data Evaluation System (MINICODES), trauma registry hospital discharge data were linked with traffic crash records. The...

Software estimation cost drivers are in many cases abstract concepts that are better estimated by breaking them down in a number of second– level aspects. This raises the need for inquiry regarding the most appropriate aggregation processes for them, since they significantly impact in the final cost estimates. Recent research on aggregation operator design has resulted in a number of families o...

OBJECTIVE To prevent the occurrence of CV events such as MI and stroke among professional drivers in Korea, bus drivers were compared to other occupations through the Framingham risk scoring system (FRS) or metabolic syndrome (MS) of cardiovascular disease (CVD) risk assessment methods. METHODS In October 2012, a health examination survey was conducted for 443 male bus drivers in a big city. ...

This thesis examines mathematical modeling as a means to improve profitability. The research is focused on studying supply chain cost drivers and their potential in regard to cost reduction in the automotive manufacturing industry, where the role of supply chain management is significant because of the capital intensive, fast paced, and high volume nature of the business. Hence, supportive tool...

This paper seeks to systematically explore the efficiency of the uncoordinated information-assisted parking search in urban environments with two types of parking resource facilities: inexpensive but limited facilities (public) and expensive yet unlimited ones (private); an additional cruising cost is incurred when deciding for a public facility but failing to actually utilize one. Drivers deci...
