In the global market, the value of software quality is a major factor in software industries. In a majority of cases, software quality needs to be quantified and measured. Previously, many models like the ISO model, the McCall model, the Boehm model, etc., have been used for the quantification of the parameters which determine the software quality. The software quality can be judged by analyzing all the characteristics of the product. In this article, a new pragmatic model which is the modification of the existing ISO Model has been proposed in order for the quantification of the software quality factors in a more precise way. Because of the nature of the attributes which determine the software quality, a Fuzzy logic-based approach is considered to be a better technique among various existing machine learning techniques. Here, the simulink tool is used for constructing the running model which helps the net quality of the software.
在全球市场上,软件质量的价值是软件行业的一个主要因素。在大多数情况下,软件质量需要被量化和度量。以前,许多模型,如ISO模型、McCall模型、Boehm模型等,已被用于量化决定软件质量的参数。通过分析产品的所有特征,可以判断软件的质量。为了更精确地量化软件质量因素,本文提出了一种新的实用模型,该模型是对现有ISO模型的改进。由于决定软件质量的属性的性质,基于模糊逻辑的方法被认为是现有各种机器学习技术中较好的技术。本文采用simulink工具构建运行模型,有助于提高软件的质量。

Pub Date : 2019-04-01 DOI: 10.4018/IJISSS.2019040105

In image segmentation, there are always some false targets which remain in the segmented image. As the grayscale values of these false targets are quite similar to the grayscale values of the targets of interest, it is very difficult to split them out. And because these false targets exist in the original image, which are not caused by noise or traditional filtering methods, such as median filtering, they cannot be eliminated effectively. It is important to analyze the characteristics of false targets, so the false targets can be removed. In addition, it should be noted that the targets of interest cannot be affected when the false targets are removed. In order to overcome above problems, a maximum inter-class variance segmentation algorithm based on a decision tree is proposed. In this method, the decision tree classification algorithm and the maximum inter-class variance segmentation algorithm are combined. First, the maximum inter-class variance algorithm is used to segment the image, and then a decision tree is constructed according to the attributes of regions in the segmented image. Finally, according to the decision tree, the regions of the segmented image are divided into three categories, including large target regions, small target regions and false target regions, so that the false target regions are removed. The proposed algorithm can eliminate the false targets and improve the segmentation accuracy effectively. In order to demonstrate the effectiveness of the algorithm proposed in this article, the proposed method is compared with some frequently used false target removal approaches. Experimental results show that the proposed algorithm can achieve better results than other algorithms.
在图像分割中,总会有一些假目标残留在分割后的图像中。由于这些假目标的灰度值与感兴趣目标的灰度值非常相似,因此很难将它们分离出来。由于这些假目标存在于原始图像中,不是由噪声或传统滤波方法(如中值滤波)引起的,因此无法有效消除。分析假目标的特征,对去除假目标具有重要意义。另外,需要注意的是,去除虚假目标后,不会影响感兴趣的目标。为了克服上述问题,提出了一种基于决策树的类间方差最大分割算法。该方法将决策树分类算法与最大类间方差分割算法相结合。首先,采用最大类间方差算法对图像进行分割,然后根据分割图像中区域的属性构造决策树;最后,根据决策树将分割后的图像区域分为三类,即大目标区域、小目标区域和假目标区域,从而去除假目标区域。该算法能够有效地消除虚假目标,提高分割精度。为了证明本文提出的算法的有效性,将本文提出的方法与一些常用的假目标去除方法进行了比较。实验结果表明,该算法能取得较好的效果。

Website Tenders Evaluation Using Fuzzy Logic 用模糊逻辑评价网站标书
Pub Date : 2019-04-01 DOI: 10.4018/IJISSS.2019040103
Dana Halabi, A. Shaout
Developing a new website for a government institution is one of common tenders issued by various ministries and government institutions in the world. The country of Jordan usually has at least 22 different ministries and government institutions at a given time. Each one of these entities has its official website which is revamped every three years because of the rapid changes in information and technology. In most cases the ministries and institutions issue a tender to the public, then after collecting tender offers from different companies, only one offer would be selected. The selection process would choose the most appropriate contractor to deliver the project with respect to quality, time and cost. This article presents a new fuzzy logic system for tender evaluation which is based on both the technical qualification of the bidder company and its experience. The proposed system has shown better performance evaluation when compared to the traditional evaluation method currently used by the government.
为政府机构开发一个新的网站是世界上各部委和政府机构发布的常见招标之一。约旦在同一时期通常至少有22个不同的部委和政府机构。每个实体都有自己的官方网站,由于信息和技术的快速变化,每三年更新一次。在大多数情况下,部委和机构向社会公开招标,然后在收集不同公司的投标报价后,只选择一个报价。选择过程将根据质量、时间和成本选择最合适的承包商来交付项目。本文提出了一种基于投标公司技术素质和经验的评标模糊逻辑系统。与政府目前使用的传统评估方法相比,该系统表现出更好的绩效评估效果。

Many researchers in Jordan tried to study customers' behavior in the domain of online shopping to understand consumers' attitudes and behaviors towards the adoption process. Still, a lot of work is to be done as customers real usage and adoption level is low which entails more research to be done to investigate the main reasons behind such behavior. In response, this article aims to shed light on consumers' attitudes towards online shopping decisions and extends the technology acceptance model ease of use, perceived usefulness) of the technology acceptance model (TAM) with four factors (trust, security, privacy, and risk). As such, 200 undergraduate and postgraduate students from Yarmouk University formulate the sample of this study. Findings indicate that the six factors are significantly impact consumers' intention to adopt online shopping. Additionally, the F-test of this study indicates that a linear relationship exists between the model's variables and consequently they can be utilized to study this process.
约旦的许多研究人员试图研究消费者在网上购物领域的行为,以了解消费者对采用过程的态度和行为。尽管如此,由于客户的实际使用和采用水平较低,因此还有很多工作要做,这需要进行更多的研究来调查这种行为背后的主要原因。作为回应,本文旨在揭示消费者对在线购物决策的态度,并将技术接受模型(TAM)的技术接受模型(易用性,感知有用性)扩展为四个因素(信任,安全,隐私和风险)。因此,来自耶尔穆克大学的200名本科生和研究生制定了本研究的样本。研究结果表明,这六个因素对消费者采用网上购物的意愿有显著影响。此外,本研究的f检验表明模型的变量之间存在线性关系,因此可以利用它们来研究这一过程。

Nowadays a lack of integration among software services and databases has become a major IT problem in many organizations including banking industries. Service oriented architecture (SOA) is the most recent and comprehensive method among the different methods and technologies proposed for integrity implementation. One of the main reasons for banks' failure in achieving the benefits of SOA is lack of a framework that includes all critical factors in SOA adoption. The aim of this article is to identify and analyze the influential factors (organizational, technical, environmental and human) on SOA adoption in e-banking and providing a comprehensive framework that explains these factors. Such a framework enhances the decision-making and enables banks to achieve the benefits of SOA. In order to gather operational data, questionnaire and interview had been used. The conceptual framework was investigated using Smart PLS and SPSS software. The empirical data investigation and interpretation shows that: organizational, technical, human and environmental factors are crucial for SOA adoption.
如今,软件服务和数据库之间缺乏集成已经成为包括银行业在内的许多组织的主要IT问题。面向服务的体系结构(SOA)是为实现完整性而提出的各种方法和技术中最新和最全面的方法。银行无法实现SOA的好处的主要原因之一是缺乏一个包含SOA采用中所有关键因素的框架。本文的目的是识别和分析影响电子银行中SOA采用的因素(组织、技术、环境和人员),并提供一个解释这些因素的综合框架。这样的框架增强了决策,并使银行能够实现SOA的好处。为了收集业务数据,采用了问卷调查和访谈法。使用Smart PLS和SPSS软件对概念框架进行了研究。实证数据调查和解释表明:组织、技术、人和环境因素对SOA采用至关重要。

Determinants and Effects of Mobile Service Customization: An Empirical Study of A2P SMS Adoption 移动服务定制的决定因素与影响:基于A2P SMS采用的实证研究
Pub Date : 2018-10-01 DOI: 10.4018/IJISSS.2018100105

Service customization enables users to custom-made services for their specific needs while service providers can use custom outputs to offer superior services for their users. Less attention, however, has been paid to what factors influence individuals to customize mobile service differently and how custom outputs affect their intentions to use the services. The article proposes a new framework to examine the effects of information seeking and user experience on service customization (service configuration and custom outputs) and the effect of the service customization on users' intentions to adopt mobile services through the three values of mobile services–utilitarian value, hedonic value, and social value. The application-to-person short messaging service (A2P SMS) is used as the domain of study. The structural equation modeling (SEM) technique was used for data analysis. The results indicate that information-seeking and user experience regulate users' abilities to customize mobile services. Specifically, information seeking affects custom outputs while user experience affects service configuration. The results also show that custom outputs influence users' intentions to adopt mobile services through the perceived values of mobile services' utilitarian value, hedonic value, and social value. Hedonic value and social value have direct effects on mobile service adoption. This article broadens knowledge and understanding of mobile service adoption and provides guidance to service providers for effectively utilizing their customization strategies to enhance users' adoption of their services.
服务定制使用户能够根据其特定需求定制服务,而服务提供商可以使用定制输出为其用户提供优质服务。然而,对于哪些因素影响个人以不同的方式定制移动服务以及定制输出如何影响他们使用服务的意图,关注较少。本文提出了一个新的框架,通过移动服务的三个价值——功利价值、享乐价值和社会价值,考察信息寻求和用户体验对服务定制(服务配置和定制输出)的影响,以及服务定制对用户采用移动服务意愿的影响。应用程序到人的短消息传递服务(A2P SMS)被用作研究领域。采用结构方程建模(SEM)技术对数据进行分析。结果表明,信息寻求和用户体验对用户定制移动服务的能力起着调节作用。具体来说,信息查找影响自定义输出,而用户体验影响服务配置。研究结果还表明,定制输出通过感知移动服务的功利价值、享乐价值和社会价值来影响用户采用移动服务的意愿。享乐价值和社交价值对移动服务的采用有直接影响。本文拓宽了对移动服务采用的认识和理解,并为服务提供商提供了指导,以有效地利用他们的定制策略来提高用户对其服务的采用。

Less attention, however, has been paid to what factors influence individuals to customize mobile service differently and how custom outputs affect their intentions to use the services. The article proposes a new framework to examine the effects of information seeking and user experience on service customization (service configuration and custom outputs) and the effect of the service customization on users' intentions to adopt mobile services through the three values of mobile services–utilitarian value, hedonic value, and social value. The application-to-person short messaging service (A2P SMS) is used as the domain of study. The structural equation modeling (SEM) technique was used for data analysis. The results indicate that information-seeking and user experience regulate users' abilities to customize mobile services. Specifically, information seeking affects custom outputs while user experience affects service configuration. The results also show that custom outputs influence users' intentions to adopt mobile services through the perceived values of mobile services' utilitarian value, hedonic value, and social value. Hedonic value and social value have direct effects on mobile service adoption. This article broadens knowledge and understanding of mobile service adoption and provides guidance to service providers for effectively utilizing their customization strategies to enhance users' adoption of their services.","PeriodicalId":151306,"journal":{"name":"Int.

The article aims to examine the relationship between the human resource practices and employees' turnover intention in United Arab Emirates health care sector. This quantitative study utilized a structure equation model (SEM) technique with Analysis of Moment Structures (AMOS) 18 software package to analyze data and to investigate the impact of human resources practices on employees' turnover intention in United Arab Emirates health care services. Results of the study showed that human resources (HRM) practices in health care sector (recruitment and selection, performance appraisal, compensation, and career development) have significant relationship with turnover intention. However, this research was limited to the Public Health Care Sector in UAE and it is recommended to include Private health care sector. Moreover, inclusion of health care workers from different emirates such as Dubai and Sharjah will be needed in future researches. Health care facilities management should have a closer look at the significant human resource practices as an initiative to restructure HRM practices, policies, procedures to increase staff satisfaction, reduce employees' turnover intention and retain its valuable health care professionals. This article is among the first and most exhaustive ones carried out in health care sector in UAE. It explores the relationship between the human resource management practices and the employees' turnover intentions.
本文旨在研究人力资源实践和员工离职意愿在阿联酋卫生保健部门之间的关系。本定量研究利用结构方程模型(SEM)技术和分析力矩结构(AMOS) 18软件包来分析数据,并调查人力资源实践对阿联酋卫生保健服务员工离职意愿的影响。研究结果表明,医疗保健行业人力资源管理实践(招聘选拔、绩效考核、薪酬和职业发展)与离职倾向存在显著关系。然而,这项研究仅限于阿联酋的公共卫生保健部门,建议包括私营卫生保健部门。此外,在未来的研究中需要包括来自迪拜和沙迦等不同酋长国的卫生保健工作者。卫生保健设施管理应密切关注重要的人力资源实践,作为重组人力资源管理实践、政策和程序的一项举措,以提高员工满意度,降低员工的离职意图,并保留其宝贵的卫生保健专业人员。这篇文章是在阿联酋卫生保健部门开展的第一篇也是最详尽的一篇文章。探讨人力资源管理实践与员工离职意愿之间的关系。
