Item Universidad Autónoma de Santo Domingo energy forecast(Association for Industry, Engineering and Management Systems, 2020-03) Llaugel, Felipe; Ridley, Dennis; Cespedes, AmparoEnergy time series data for Universidad Autónoma de Santo Domingo is analyzed and forecast by the moving window spectral method to capture cyclical components and effects. The historical record is 217 months from March 2001 to March 2019. A model is fitted to 205 historical observations from March 2001 to March 2018. The forecast period is 12 months from April 2018 to March 2019. The two overlapping 12 actual and forecast months are compared.Item Effects of verbal versus graphical weather information on a pilot's decision-making during preflight(Association for Industry, Engineering and Management Systems, 2020-03) Pittorie, Warren; Carstens, Deborah S.; Carroll, MeredithThis study focused on the older technology of a verbal preflight weather briefing compared with the newer and emerging technology of digital textual and graphical weather pertinent to the flight route the pilot has chosen. The target population for this study was aviation students and instructors at Part 61 and 141 flight schools across the country. The accessible population for this study was flight students at a Florida university that had at least a private pilot's license through being employed as flight instructors. The 36 participants were selected from the accessible population based upon their availability and willingness to participate in the study. Institutional Review Board (IRB) approval was obtained from the university before conducting trials with human subjects. Two weather scenarios were selected for the trials. Participants were assigned to one of four groups based on the order of the two formats, verbal or visual (graphical/textual), for the two different scenarios. Four open-ended questions for the two weather scenarios were given to participants, which resulted in a total of eight open-ended questions per participant. The open-ended questions designed and included in the instrument captured the "why" behind pilots' decision to "go" or "no-go." The qualitative analysis software, Nvivo®, was used to analyze the four open-ended questions for each of the two weather scenarios. To visualize this data, a diagram was formed. The study results, discussion, and future research are presented in the paper.Item Drivers and barriers of advanced manufacturing technology implementation in Saudi Arabia(Association for Industry, Engineering and Management Systems, 2020-03) Al Fatais, Abdullah; Almuflih, AliThe purpose of this paper is to present a systematic literature review to identify opportunities and challenges that face Advanced Manufacturing Technology (AMT) adoption in Saudi industrial sector. It also highlights the critical factors behind those opportunities and challenges, which need to be taken into consideration when it comes to AMT implementation. This study uses a systematic review of the literature contained in the two databases ProQuest, and Compendex and on the search engine Google Scholar. Moreover, the study highlights a gap in the research efforts for identifying the need for effective integration and interaction between the eight different categories mentioned previously for both developed and developing economies. For that reason, it is recommended that researchers adopt a broader view that includes the role of integration and interaction between critical factors in each category and their impact on AMT adoption. The systematic literature review in this study used to review all vital elements of adopting AMT and identifies new research avenues and different approaches to implementing AMT, focusing on the integration between the different categories that can be used for AMT adoption in Saudi Arabia.Item Integrating BIM in construction takeoff and estimating: A case study of an advanced cost estimating course for construction management(Association for Industry, Engineering and Management Systems, 2020-03) Huang, YileiAs Building Information Modeling (BIM) is becoming the standard practice for design, engineering, and fabrication in the construction industry, Construction Management (CM) programs have started to introduce BIM for cost estimating in their curriculum. Many CM programs consider model-based quantity takeoff merely as an alternative approach to the traditional plan-based quantity takeoff. The disconnection between automated quantity takeoff and cost estimating, however, still exists. In addition, without fully understanding the role of BIM in preconstruction, students will only use BIM models as 3D representation of the plans without realizing the benefits that the BIM process brings to the project lifecycle. This paper presents a newly developed Advanced Cost Estimating course for CM programs that focuses on integrating BIM in both the takeoff and estimating process. The course is structured based on the UniFormat divisional system and uses RSMeans building assemblies for bid pricing. The course streamlines the connection between model-based quantity takeoff and cost estimating with the help of the latest construction software programs. By applying a combination of three different computer programs, quantity data from a BIM model can be seamlessly transferred to a construction cost database for bid pricing and reporting. Student survey at the end of semester suggested that using BIM models for construction takeoff and estimating with building assemblies can greatly improve student understanding of knowledge and consequently strengthen the learning outcomes. This paper provides an empirical case study with valuable insights on how to integrate BIM in a cost estimating course in a CM program.Item Enhancing an organization's output through re-engineering of administrative processes(Association for Industry, Engineering and Management Systems, 2020-03) Kanan, Mohammad A.This research implements a descriptive approach in preparing a theoretical framework for reengineering administrative processes. The objective of this work is to identify the administrative processes to be considered and to quantify the benefits of applying the re-engineering processes. A field study was performed to determine the feasibility of applying the proposed framework in companies operating in Jeddah, Kingdom of Saudi Arabia. The study included a selected sample of projects from various service and manufacturing sectors. The results supported the need for re-engineering the administrative processes to help achieve tangible improvements in efficiency, productivity, and profitability.
