Likewise little information is available about the geography, potential sites for mining sand as well as the evaluation of sand quality. This paper attempts to bridge this gap by presenting a feasibility study of fabricating normal glass and glass ceramics from Saudi Arabia’s domestically available raw materials. It discusses the current status of glass industry in Saudi Arabia and the Middle East region. It also gives a brief explanation about the sand topography in Saudi Arabia. In order to determine the feasibility of fabricating glass using these raw materials, experimental data on the fabrication of normal glass and glass-ceramics from indigenously available raw materials was obtained and reported as part of the findings of this paper Firstly, normal transparent glass were able to be fabrica...

The article reports on a study to identify key components which can be used to relate ergonomics awareness and safety culture. These components can be used to facilitate the research which is aimed at determining the elements that influence the ergonomics awareness and the relationship with safety culture in an organization. A survey was done using a sample of 108 OSH practitioners in manufacturing companies in Malaysia. Exploratory Factor Analysis was used to determine the importance of ergonomics at their workplace and their beliefs on the importance of safety culture to be inculcated at their companies. 3 factors for ergonomics importance were identified: (i) Implication of & Need for improvement, (ii) Fitting the job to the workers and (iii) Basic ergonomics consideration. Safety culture questions were focused on the OSH practitioners perceptions on safety climate importance. Three constructs were designed: (i) commitment and leadership, (ii) motivation and (iii) safety management system practice. This finding is significant in order to study the influence of the perceptions of OSH practitioners on ergonomics importance at workplace to the safety culture.

This has considerably affected the students’ performance in Statics and other follow-on courses, and consequently, disheartened them from pursuing engineering as a career [4, 5] . However, findings from previous researches showed that good academic performance on assessment alone does not necessarily reflect the engineering students’ deep understanding of the fundamental concepts [6, 7] . Steif [8] suggested that apart from the universal issues such as the hard to learn concepts, the local culture and students’ work habits contribute to this continual problem . In an earlier survey conducted by the authors, most students attributed their performance in Statics to their own efforts in learning. Therefore, this paper investigates the influence of students’ motivational factors in learning for understanding and learning for achieving good performance through statistical data analysis an...

However, an essential process for the recycling and/or reuse/remanufacturing of end-of-life products is product disassembly. This entails large amounts of capital expenditure, and most manufacturers would not like to even consider disassembling and remanufacturing unless capital costs are justified and financial gains assured. To enhance the recycling process, it is necessary to analyze the product from the end-of-life point of view. Without the understanding of end-of-life aspect, the ease of disassembly and recycling of a product can hardly be enhanced. Therefore, there is a strong need for developing a new methodology to evaluate the product disassemblability aspect and to determine its technological and economic impact at the end-of-life. This paper presents a new methodology to f...

While several of these components have been subjected to a variety of scholarly studies, both individually and in relation to one another, a number of organizational components still require deeper investigation. The present study looks at the direct and indirect effects of transformational leadership (TL) on organizational innovation (OI) through management control system (MCS) as a mediating variable. This objective has been achieved through an exhaustive review of the literature on the impacts of TL and MCS on OI. The data were collected through questionnaire distribution among 400 high-level managers of seven universities in Saudi Arabia, within the period of May–July 2019. Subsequently, 264 surveys were acquired for the final analysis, indicating 66 per cent accuracy in the response rate. Furthermore, Partial least squares SmartPLS 3.0 used to assess the measurement model and the structural mo...

It has been a challenge to identify the key performance indicators for a sustainable warehouse management system and to develop a model for evaluating the direct and indirect indicators. In order to overcome this challenge, this paper describes a method to identify and weight indicators that assess sustainability in a sustainable warehouse management system using structural equation modeling. A comprehensive literature review has been conducted and a questionnaire survey involving experts in the field has been undertaken. A list of 33 key performance indicators for a sustainable warehouse management system has been proposed, and this can be used by policymakers to appraise the sustainability performance of a sustainable warehouse management system. The proposed robust model can weight indicators and evaluate the total effect of each indicator in incorporating sustainability in a sustainable warehouse management system. The developed method could also be applied to weighting indicators for other industries.

Data from the academic session 2004/2005 to 2007/2008 showed an average of 34 percent of students per semester not graduating on time. Compared to other pre-requisite and follow-on courses, students’ achievements in ‘Statics’ which students took as their first engineering course in the first year showed an average of 21 percent failures per semester for semesters 1-2004/2005 to 2-2007/2008, with the highest record of 46 percent and the lowest of 13 percent. Among these students 19 percent managed to pass after retaking the course for the third time and another 15 percent were either terminated or withdrew from the program. Based on this initial analysis, a study was conducted to examine the pedagogical issues related to the teaching and learning (T&L) of Statics. The main concerns were highlighted and will be the basis for identifying appropriate strategies for improvement. Implications from the findings would be useful to those involved in academia

As a consequence, the solutions obtained from the traditional scheduling technique are ineffective wherever changes occur to the system. Therefore, this research intends to develop a decision support tool (DST) based on promising artificial intelligent that is able to accommodate the dynamics that regularly occur in job shop scheduling problem. The DST was designed through three phases, i.e. (i) the look-up table generation, (ii) inverse model development and (iii) integration of DST components. This paper reports the generation of look-up tables for various scenarios as a part in development of the DST. A discrete event simulation model was used to compare the performance among SPT, EDD, FCFS, S/OPN and Slack rules; the best performances measures (mean flow time, mean tardiness and mean lateness) and the job order requirement (inter-arrival time, due dates tightness and setup time ratio) which were compiled into look-up tables. The well-known 6/6/J/Cmax Problem from Muth and Thompson (1963) was used as a case study. In the future, the performance measure of various scheduling scenarios and the job order requirement will be mapped using ANN inverse model.

As a consequence, the solutions obtained from the traditional scheduling technique are ineffective wherever changes occur to the system. This project profile reports on the development of an improved model for solving dynamic job shop scheduling problem. The model refers to as a decision support tool (DST) was developed using discrete event simulation, artificial neural network, and database techniques. An integrated reference model for guiding in design and development of the DST for dynamic job shop scheduling is presented. The experimental results provide evidence that the prototype DST system is promising and able to effectively satisfy multiple scheduling objectives.

As a consequence, the solutions obtained from the traditional scheduling technique are ineffective wherever changes occur to the system. The Decision Support Tool (DST) for dynamic job shop scheduling was developed. The components of DST, namely, the knowledge-base, data-base, rule base, and graphical user interface were integrated. It provides alternative recommended schedules to be selected by practitioners with minimum knowledge in job shop scheduling. Validation of DST shows that the performance of DST is promising and able to provide comparable results as when using discrete event simulation. This paper demonstrates the capability of the DST to handling changes in demand, i.e. job cancellation. The demonstration suggests that the proposed DST can effectively handle jo...
