Building a software architecture that meets functional requirements is a quite consolidated activity, whereas keeping high quality attributes is still an open challenge. In this paper we introduce an optimization framework that supports the decision whether to buy software components or to build them in-house upon designing a software architecture. We devise a non-linear cost/quality optimization model based on decision variables indicating the set of architectural components to buy and to build in order to minimize the software cost while keeping satisfactory values of quality attributes. From this point of view, our tool can be ideally embedded into a Cost Benefit Analysis Method to provide decision support to software architects. The novelty of our approach consists in building costs and quality attributes on a common set of decision variables related to software development. We start from a special case of the framework where the quality constraints are related to the delivery time and the product reliability, and the model solution also devises the amount of unit testing to be performed on built components. We generalize the framework formulation to represent a broader class of architectural cost-minimization problems under quality constraints, and discuss advantages and limitations of such approach. 相似文献

When developing packaged software, which is sold ‘off-the-shelf’ on a worldwide marketplace, it is essential to collect needs
and opportunities from different market segments and use this information in the prioritisation of requirements for the next
software release. This paper presents an industrial case study where a distributed prioritisation process is proposed, observed
and evaluated. The stakeholders in the requirements prioritisation process include marketing offices distributed around the
world. A major objective of the distributed prioritisation is to gather and highlight the differences and similarities in
the requirement priorities of the different market segments. The evaluation through questionnaires shows that the stakeholders
found the process useful. The paper also presents novel approaches to visualise the priority distribution among stakeholders,
together with measures on disagreement and satisfaction. Product management found the proposed charts valuable as decision
support when selecting requirements for the next release, as they revealed unforeseen differences among stakeholder priorities.
Conclusions on stakeholder tactics are provided and issues of further research are identified, including ways of addressing
identified challenges. 相似文献

基于COTS软件系统的包装器及其接口设计 总被引:1,自引:0,他引:1
基于COTS的软件开发(COTS-BasedSoftwareDevelopment)方法日益受到重视,文章针对COTS软件的特点,提出了一种抽象的包装器模型,并给出了这种包装器模型的接口的设计方法。这种包装器模型进一步具体化可以把COTS软件包装成COM组件、CORBA组件以及JavaBean组件,通过包装器接口的组织还可以实现COTS软件功能的增加和屏蔽。 相似文献

The goal of the GUARDS project is to design and develop a generic fault-tolerant computer architecture that can be built from
predefined standardised components. The architecture favours the use of commercial off-the-shelf (COTS) hardware and software
components. However, the assessment and selection of COTS components is a non-trivial task as it requires balancing a myriad
of requirements from end-users and the preliminary architecture design. In this paper, we present the requirements and assessment
criteria for a specific COTS software component, the operating system kernel. As an interface specification constitutes a
major compatibility criterion for the selection of COTS components in GUARDS, a particular emphasis is placed on operating
system conformance to the POSIX 1003.1 standard. We discuss the general lessons learned from the assessment process and raise
a number of questions relevant to the assessment of any COTS software component. 相似文献

This paper describes the baseline corpus of a new multimodal biometric database, the MMU GASPFA (Gait–Speech–Face) database. The corpus in GASPFA is acquired using commercial off the shelf (COTS) equipment including digital video cameras, digital voice recorder, digital camera, Kinect camera and accelerometer equipped smart phones. The corpus consists of frontal face images from the digital camera, speech utterances recorded using the digital voice recorder, gait videos with their associated data recorded using both the digital video cameras and Kinect camera simultaneously as well as accelerometer readings from the smart phones. A total of 82 participants had their biometric data recorded. MMU GASPFA is able to support both multimodal biometric authentication as well as gait action recognition. This paper describes the acquisition setup and protocols used in MMU GASPFA, as well as the content of the corpus. Baseline results from a subset of the participants are presented for validation purposes. 相似文献

针对基于商用现成组件技术(Commercial Off-The-Shelf,COTS)的交换式以太网不能满足工业数据通信的实时性要求问题,给出了改进的FTT(Flexible Time-Triggered communication paradigm)网络调度模型,提出了新的周期性实时消息链路可调度性优化判定方法,在此基础上设计了一种基于EDF(Earliest Deadline First)的实时调度算法。算法通过对网络消息流量进行有效控制防止交换机缓冲区溢出,同时充分发挥网络在同一时间存在多个并行传输链路的优势,提高了网络实时性。仿真实验表明该算法在提高网络的聚合带宽、减小消息的平均等待延时和丢失率方面均有明显的优势。 相似文献
