––Software development cost estimation is important for effective project management. Many models have been introduced to predict software development cost. In this paper, a novel emotional COnstructive Cost MOdel II (COCOMO II) has been proposed for software cost estimation. In COCOMO II only the project characteristics are considered, whereas the characteristics of team members are also impor...

Accurate software cost and schedule estimation are essential for software project success. Often it referred to as the “black art” because of its complexity and uncertainty, software estimation is not as difficult or puzzling as people think. In fact, generating accurate estimates is straightforward—once you understand the intensity of uncertainty and framework for the modeling process. The mys...

Effort is the main cost in software development projects, and software size is the main input for effort estimation. Project managers need to have sound size estimations to estimate required software effort. The inputs for size estimation models are generally software artifacts that are produced later in software development life cycle; however project managers need the estimations prior to the...

Knowledge-based systems have traditionally been implemented in vertical application areas, which are characterized by a deep knowledge in a narrow domain. We developed and fielded a successful knowledge-based tool that is characterized by shallow knowledge of a wide range of cost-estimation problems. Our system is used to estimate piece-part manufacturing costs and has broad knowledge of many c...

LCC theory study on the green construction of economic benefit based on the LCC theory, the concept of full description, a detailed analysis of the existing building economic cost estimation methods, combined with the data, only provides theoretical basis for green construction cost control. Because our country is in the LCC theory and the building materials recycling research is still not perf...

Project cost estimation in the bidding process is a critical concern for the competitiveness and profitability of an engineering and contracting company. Estimates which diverge as little as possible from actual costs have to be made on the basis of relatively limited information. Of the macro-items contributing to the overall cost of a plant project, those linked to engineering activities have...

Software project development process is requiring accurate software cost and schedule estimation for achieve goal or success. A lot it referred to as the ―Intricate brainteaser‖ because of its conscience attribute which is impact by complexity and uncertainty, Generally estimation is not as difficult or puzzling as people think. In fact, generating accurate estimates is straightforward—once you...

Separate investment functions are estimated for expenditure on “plant and equipment” in two sectors of the Luxembourg economy: Tradables (manufacturing, international transport and international communications) and Non-Tradables (construction, retail, domestic transport and domestic communications). The theoretical framework is derived from the neoclassical model of investment based on a Consta...
