Complexity is a term that is currently used not only in research articles but also in the methodologies and standards used to manage information and projects. The complexity can represent the size of a system, process, program or project, the number of functions and the cost of their acquisition, operation and maintenance. Within the context of this work, the complexity is a variable that represents...
The Last Planner System is a very important and systematic method that influences the achievement of lean construction. With the theory of emergence science, this paper analyzed the emergence mechanism of the last planner system from the perspective of group decision-making, information change and self-organization; then, how to realize the potencies of the last planner system so as to attain much...
CMMI (Capability Maturity Model Integration) models are collections of best practices that help organizations improve their processes. This article reports on the authors' experience in achieving and maintaining CMMI Maturity Level 5 in a small organization. Economic achievements, success factors, and lessons learned are reported by using real-life examples from almost 10 years of improvement process...
Nowadays, activities and decisions making in an organization is based on data and information obtained from data analysis, which provides various services for constructing reliable and accurate process. As data are significant resources in all organizations the quality of data is critical for managers and operating processes to identify related performance issues. Moreover, high quality data can increase...
Land reserving enables the government to control land market easily and reduces the rent-seeking behaviors in the process of assigning the right to the use of the land. The land reserving could move the stock of urban land and improve the land utilization. However, the land revserving projects also belong to investment activities and the amount of investment is huge. In the same time the investment...
In this paper, physical speed event group was taken as the carrier, and AHP(Analytic Hierarchy Process) was adopted to determine the weight values in the four-level elements of the competition structure. Meanwhile, Kendall coefficient of concordance was used to exam the reliability of weight evaluation and Cronbach coefficients to make a consistent internal mathematical test of four-level elements...
To realize the integration of different software systems, this paper introduces the agent technology and proposes one strategy, SCITR (scripting control integration strategy based on task-reduction method), that is used to achieve the agent system integration. Application of SCITR is based on the special agent structure and agent cooperation mechanism. Firstly, this paper respectively studies the...
With an increased focus on national security and public safety communications, the US Congress revisited its plan to reclaim television broadcaster frequencies to be reallocated and auctioned by the FCC and it specifically allocated a portion of that spectrum for use by public safety. The FCC was charged with the duty of auctioning this spectrum and licensing it to create a public safety network....
An organizational level test strategy needs to incorporate metrics to make the testing activities visible and available to process improvements. The majority of testing measurements that are done are based on faults found in the test execution phase. In contrast, this paper investigates metrics to support software test planning and test design processes. We have assembled metrics in these two process...
In this paper, we propose a cognitive radio-based multi-user resource allocation framework for mobile ad hoc networks using multi-carrier DS CDMA modulation over a frequency-selective fading channel. In particular, given pre-existing communications in the spectrum where the system is operating, in addition to potential narrow-band interference, a channel sensing and estimation mechanism is provided...
