Due to recent environmental and Political requirements, and regulations of the construction industry, in which bridges is one of its important category, deciding its proper constructability is becoming vital. Therefor the objective of this research is to develop a decision model for selecting proper constructability of green bridges constructions, the model was built based on analytical network process (the ANP) soft were program, integrated with value engineering approach. For this analytical study different parameters are identified and ranked to be implemented for the decision model developed on the biases of four surveying studies conducted in this study the results of these surveying's was be analyzed by using the statically analytical program; "SPSS". Model validation and reliability is carried out using the analytical network process (ANP) for statistically analysis using case study which is a cable bridge project constructed in Egypt. ANP proves to be an effective framework for assessing readiness to adopt and facilitating TQM. The result of the study illustrate that the proper constructability alternative in green bridge concept for this determinate project is the concrete box girder type, upon this there is a cost loss of $3, 500 per square meter, equivalent to 50% losses, respect to the life cycle cost this is due to did not using the best alternate of the estimated project. upon the possibility of applying this decision model to such studies of infrastructure projects, and with respect to the results gained; it is recommend to apply the ANP model with respect to VE procedures to bridges projects of all kinds and their determinants, as well as all other construction projects, especially national ones, in future studies, which allows decision- makers to make decisions that aim at the highest quality without any waste in unnecessary costs.

In this chapter we propose functional specifications and a component-based architecture for designing e-learning platforms. An important feature is that the proposed specifications and architecture are based on the experience gained in an e-learning company and result from a reengineering process. To guide the reengineering process, we used two reference models, which are the e-learning global process and the e-learning global cycle. The functional specifications are described according to the e-learning global cycle phases and they are used to propose a software component based architecture. The proposed kernel of components was completed with services to allow interoperability and standard compliance between several e-learning platforms. We hope that this case-study exemplifies e-learning platform suppliers’ needs and available pragmatic solutions. We conclude on foreseeable evolutions of e-learning actors needs and practices and on new platform features for fulfilling such needs.

Conformance to social context while designing an e-learning course is crucial in enhancing acceptability of the course. Building socially aware e-learning courses requires elicitation of social opinion from various stakeholders associated with the system. Stakeholders are disparate in their perception towards the intricacies of the system, leading to generation of numerous assorted ideas. Knowledge Management (KM) assimilates these ideas to bring congruency into the system. This paper proposes i) a model KMeLS (Knowledge Management in e-Learning Systems) built upon the SECI (Socialization, Externalization, Combination and Internalization) framework, and ii) an algorithm PARSeL (Prioritizing Alternatives using Recommendations of Stakeholders in e-Learning) to incorporate KM into designing an e-learning course. PARSeL prioritizes the content using stakeholder recommendations using Analytic Hierarchy Process (AHP) and fuzzy modeling. A case study is also presented with a goal of prioritizing a set of programming languages for an online computing course. The proposed methodology can be promising in recommending appropriate content for the e-learners and can be implemented to benefit e-learning organizations in a wider spectrum.

The E-learning systems are important for the universities due to the gained benefits from these systems. By using the E-learning system, the learning expenses can be reduced, the learning management would be improved, and the learning quality could be enhanced. Like any technology system, the students' motivation and positive attitude are success keys of the E-learning adoption by the universities. There are many difficulties faced by the students in using the E-learning system such as the technical difficulties, services difficulties, awareness, interactivity, and security concerns. This study aims to study the effects of the E-learning difficulties on the attitudes of using the E-learning systems through the path of students' motivation. The Technology Acceptance Model (TAM) is adopted to construct the conceptual model in this study. This study considered the E-learning difficulties as independent factor, the mediating factor is the motivation of using the E-learning systems, and the dependent factor is the attitudes toward the using of the E-learning systems. Based on the constructed model, three research hypotheses are developed to test the relationship between the E-learning difficulties and motivation, between motivation and attitudes, and between difficulties and attitudes through the motivation. The quantitative data method using questionnaire is used to collect the study data. The data collected from 154 students from Ajloun University as a case study of Jordanian universities. The case study is selected due the experience of the students in using E-learning system called BigBlueButton. The questionnaire data were analyzed using AMOS tool in order to discover the direct and indirect paths between the study variables. The significant results show that there moderator effects of the students motivation on the relationship between the E-learning difficulties and the attitudes toward the using of these systems. The P-values is significant at p < 0.05 on the relationship between the study variables. Another important result is that the difficulties of E-learning such as technical, services, and interactivity should be avoided to improve the motivation level of using the E-learning systems. Also, the low motivation level lead to decrease the attitudes level toward the using of E-learning systems. The contribution of this study represented by fill the research gap of the motivation path on the relationship between the E-learning difficulties and attitudes. This study gives the university important details about the features of success implementations of E-learning systems.
