功能规模度量(FSM)方法通过量化用户功能需求(FUR)而得到软件功能规模。针对不同的功能规模度量方法都是使用不同的抽象来描述一个软件系统的问题,提出了一种通用的FSM模型。根据软件系统的抽象模型,首先对度量所涉及的数据组和事务进行了泛化,然后以IFPUG FPA为例详细说明了该通用模型和FPA之间的转换过程,最后给出了度量过程的算法描述。 相似文献

Software measurement is considered important in improving the software process. However, teaching software measurement remains
a challenging issue. Although, games and simulations are regarded powerful tools for learning, their learning effectiveness
is not rigorously established. This paper describes the results of an explorative study to investigate the learning effectiveness
of a game prototype on software measurement in order to make an initial judgment about its potential as an educational tool
as well as to analyze its appropriateness, engagement and strengths & weaknesses as guidance for further evolution. Within
the study, a series of experiments was conducted in parallel in three master courses in Brazil. Results of the study reveal
that the participants consider the content and structure of the game appropriate, but no indication for a significant difference
on learning effectiveness could be shown.

The development of the Quick Exposure Check (QEC) for assessing exposure to risk factors for work-related musculoskeletal disorders 总被引:1,自引:0,他引:1
This paper describes the development and evaluation of the Quick Exposure Check (QEC), which is an observational tool developed for Occupational Safety and Health (OSH) practitioners to assess exposure to risks for work-related musculoskeletal disorders and provide a basis for ergonomic interventions. The tool is based on epidemiological evidence and investigations of OSH practitioners' aptitudes for undertaking assessments. It has been tested, modified and validated using simulated and workplace tasks, in two phases of development, with participation of 206 practitioners. The QEC allows the four main body areas to be assessed and involves practitioners and workers in the assessment. Trials have determined its usability, intra- and inter-observer reliability, and validity which show it is applicable to a wide range of working activities. The tool focuses primarily on physical workplace factors, but also includes the evaluation of psychosocial factors. Tasks can normally be assessed within 10min. It has a scoring system, and exposure levels have been proposed to guide priorities for intervention. Subsequently it should be used to evaluate the effectiveness of any interventions made. The QEC can contribute to a holistic assessment of all the elements of a work system. 相似文献

基于Web应用的全面功能点的改进 总被引:1,自引:0,他引:1
全面功能点(FFP)是一种应用广泛且使用方便的软件功能规模度量(FSM)方法,但其方法本身只能度量系统静态的方面,不能考虑到对象的交互性和对象的行为。根据COSMIC-FFP的度量元素和Web应用的结构,对COSMIC-FFP软件模型进行了改进,列出了针对Web应用的度量规则,并给出了实例说明了这些规则的使用。 相似文献

In this paper, we develop the idea of a universal anytime intelligence test. The meaning of the terms “universal” and “anytime” is manifold here: the test should be able to measure the intelligence of any biological or artificial system that exists at this time or in the future. It should also be able to evaluate both inept and brilliant systems (any intelligence level) as well as very slow to very fast systems (any time scale). Also, the test may be interrupted at any time, producing an approximation to the intelligence score, in such a way that the more time is left for the test, the better the assessment will be. In order to do this, our test proposal is based on previous works on the measurement of machine intelligence based on Kolmogorov complexity and universal distributions, which were developed in the late 1990s (C-tests and compression-enhanced Turing tests). It is also based on the more recent idea of measuring intelligence through dynamic/interactive tests held against a universal distribution of environments. We discuss some of these tests and highlight their limitations since we want to construct a test that is both general and practical. Consequently, we introduce many new ideas that develop early “compression tests” and the more recent definition of “universal intelligence” in order to design new “universal intelligence tests”, where a feasible implementation has been a design requirement. One of these tests is the “anytime intelligence test”, which adapts to the examinee's level of intelligence in order to obtain an intelligence score within a limited time. 相似文献
