Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...

The challenges posed by global climate change are motivating the investigation of strategies that can reduce the life cycle greenhouse gas (GHG) emissions of products and processes. While new construction materials and technologies have received significant attention, there has been a limited emphasis on understanding how construction processes can be best managed to control GHG emissions. Unex...

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 ...

We describe robust optimization procedures for controlling total completion time penalty plus crashing cost in projects with uncertain activity times. These activity times arise from an unspecified distribution within a family of distributions with known support, mean and covariance. We develop linear and linear-based decision rules for making decisions about activity start times and the crashi...

Anthropogenic emissions have a significant effect on Earth’s atmosphere and contribute to changes in the global climate. These emissions and their impacts need to be tracked in order to understand their potential consequences and to be able to determine how these impacts can be eliminated or reduced by changes in methods, behaviors, and tools. A carbon footprint is the amount of carbon dioxide ...

Project cost is the main factor contributing to the cost of construction, which accounts for a large proportion of the total investment. So strengthening the management and control of the project cost will be beneficial for the improvement of international competitiveness and conservation of social resource for construction enterprises. The article applies the basic principles of fuzzy mathemat...

Project management plays an important role in software engineering discipline. Project management is about delivering projects “on time”, “in budget” and “in quality”. Introducing, applying and improving project management process requires systematical and coordinated approach, which helps to overcome organizational barriers, reduce implementation cost, provide knowledge sharing and secure achi...

The costing and data mining of logistics costs will become increasingly important to all firms seeking competitive advantages. Activity Based Costing (ABC) is considered as the optimized and most promising method of costing and controlling logistics cost now, and logistics cost data mining based on ABC is playing a very important role in business management. The paper firstly analyses the princ...
