Proper supplier selection is very critical because a significant proportion of income is allocated for and spent on purchased items. This paper presents a supplier selection model for oil and gas projects in the United Arab Emirates (UAE). This model is designed to guide users in selecting the most suitable supplier. The supplier selection decision is based on several criteria. The proposed model consists of five stages: item selection, initial supplier selection, selection criteria, supplier evaluation, and selection decision. It allows the decision makers to select the most suitable supplier to execute the job. Decision makers can evaluate the results based on the suppliers' ranking and the sensitivity of the case. A real case study is presented to demonstrate the application of the model. ©Civil-Comp Press, 2015.

A system for automatic detection of road damages is essential for logistics management. At the core of the system lies an algorithm for classification of damages. This work intends to establish such an algorithm. In the current proposal, the algorithm receives data of the probe vehicle rate of rotations, extracts statistics descriptive from the data to produce a feature vector, and finally, feeds the vector to a simple-three-layer neural network to classify the damages. The types of damages are limited to four cases: normal, pothole, speed bump, and expansion joint. For the development, a probe vehicle is used to produce 400 empirical data involving those four damage cases. By using Monte Carlo approach, the established neural network model is evaluated. The results show that the approach is able to classify the cases with 85% accuracy. The study also finds that the rates of pitch and roll to be the determining factors. © 2018 Institute of Physics Publishing. All rights reserved.

Maritime shipping plays a pivotal role in the global transportation system, providing safety and cost-effectiveness. However, it encounters numerous challenges, including port congestion, delivery delays, complex paperwork, unreliable reports on hazardous materials, and difficulties in tracing containers. To address these issues and mitigate risks associated with the transportation of hazardous goods, researchers have explored the implementation of blockchain technology in the maritime sector. Blockchain offers decentralization, transparency, and auditability of transactions, as well as the ability to trace and track cargo, particularly hazardous materials. Despite its potential, there is limited research available on the practical implementation of blockchain for hazardous material traceability. This research paper aims to investigate the application of blockchain technology in enhancing hazardous material traceability in seaports, contributing to the growing body of knowledge regarding blockchain's potential in this area and providing valuable insights for future research and practical implementations. Moreover, the paper suggests a preliminary framework for an optimized blockchain algorithm for hazardous material traceability. The main findings highlight the significant potential of blockchain technology in improving traceability of hazardous materials in seaports. Real-time tracking and monitoring of hazardous materials from origin to destination can be achieved through blockchain's distributed nature, reducing the risk of data manipulation or fraud. The immutability of blockchain records ensures the integrity and accuracy of critical data related to material composition, handling procedures, and safety certifications. Furthermore, blockchain's decentralized control allows for collaborative traceability in seaports, involving stakeholders such as port authorities, shipping companies, regulatory bodies, and manufacturers.

Incorporating social vulnerability (SoV) into vulnerability assessments for protected areas provides critical insights for enhancing the resilience and adaptability of these regions to environmental hazards. This study aimed to develop and apply an integrated social-ecological vulnerability assessment framework for a forest-protected area, focusing on scales relevant to management decisions. We collected data from 70 villages within the protected area through structured surveys, interviews, and reviews of secondary socio-economic and environmental datasets. A total of 24 socio-economic and environmental indicators were selected, based on expert consultation and literature review, to quantify the indices of exposure, sensitivity, adaptive capacity, and SoV. These indicators were weighted using the Fuzzy Analytical Hierarchy Process (FAHP) to ensure objective and expert-driven prioritization. Subsequently, the SoV index, derived from socio-economic metrics, was incorporated as a key variable in the exposure assessment. This integration involved 18 additional ecological indicators measured across a spatial grid, enabling a fine-scale analysis of the protected area's exposure, sensitivity, adaptive capacity, and overall vulnerability. Integrating social and ecological dimensions allowed for a spatially explicit evaluation of vulnerability at the grid-cell level, providing granular insights for localized management interventions. The results revealed that SoV significantly influenced the levels of exposure and overall vulnerability across the study area. High SoV values corresponded to areas with elevated overall vulnerability, emphasizing the interplay between social conditions and ecological risks. To enhance resilience in the medium and long term, the study recommends shifting investments toward active community engagement in conservation planning, increasing environmental awareness through education programs, and improving the socio-economic well-being of local commu

The Japanese concept 'poka yoke', translated into English as 'mistake proofing,' has been mentioned at previous IGLC conferences. This notwithstanding, mistake proofing appears to not have been (nor be) systematically researched or practiced in the lean construction community. To raise awareness of opportunities provided by thinking with mistake proofing in mind as a means to build quality into project delivery, this paper summarizes the philosophy that underlies mistake proofing. Examples illustrate how mistake proofing applies to the work done within one specialty trade, how manufacturers and fabricators can design their products so they cannot be constructed defectively, and how architects and engineers may conceive of system designs that are less likely to fail during construction or in a product's life cycle. Reader contributions to an online repository of mistake proofing applications in the architecture-engineering-construction (AEC) industry, posted at http://***/pokayoke/, will be gratefully acknowledged.

This paper discusses the optimization of hyperparameters of the Multilayer Feedforward (MLF) Artificial Neural Network (ANN), for Automatic Incident Detection (AID) within freeway systems. The MLF model was developed and tested using simulated data generated from VISSIM traffic simulation software. The optimized hyperparameters include the number of hidden layers, the size of hidden layers, the learning rate, momentum, error epsilon, and training cycles. To reduce computational time, a stepwise approach was adopted to optimize these hyperparameters. The model's performance was evaluated based on the Fscore, which is the harmonic mean of the recall and precision metrics. This evaluation metric was used because the AID is an imbalanced binary classification problem, where normal instances are the majority class and incident instances are the minority class. The results showed that optimizing the hyperparameters of the MLF model resulted in a 0.79% improvement in the F-score of the model and a 0.32% improvement in the overall accuracy of the model. The near-optimal hyperparameters for the MLF model were determined to be 1 hidden layer with 35 neurons, a learning rate of 0.015, momentum of 0.9, an error epsilon of 1.00E-10, and 1000 training cycles. The study provides insights into optimizing the hyperparameters of ANNs for AID applications in traffic management systems, which can help improve the performance of such systems. The optimized model can be utilized by Traffic management Centres (TMCs) to detect incidents accurately and in a timely manner, thereby reducing the negative impacts of traffic incidents and ensuring safe and efficient travel for drivers. © 2023 Computers and Industrial engineering.

Increasing energy demands globally have accelerated the development of renewable technologies including solar photovoltaics (PV). However, this development has unavoidably led to the emergence of significant volumes PV waste considering 20-30 years life span before End of Life (EOL). The standard decision makers practices for PV EOL are disposal to the landfill, recycling, or reuse. Due to complexity of the decision environment, this study aims to analyze and rank solar PV disposition alternative using Analytic Hierarchy Process (AHP) based on five main criteria including environmental, economic, social, policy and legislation and technical. AHP Aggregating Individual Priorities (AIP) aggregation method was utilized to evaluate the overall perspective of all the study participant. In addition, individual stakeholder group decision was assessed individually to understand potential different EOL disposition perspective from different stakeholder group. The findings of the analysis shows that the overall ranking of the alternatives based on the main criteria is leaning toward recycling compared to other alternatives. However, there is a variation in the decision between individual stakeholder group. © 2023 IEEE.

Overall Equipment Effectiveness (OEE) is an indicator frequently used for measuring efficiency of critical equipment. Typically presents a negative asymmetrical distribution, limited to the interval [0;1]. Due to this characteristic, it is uncommon using statistical control procedures for monitoring OEE. This study aims to contribute to this discussion by presenting an approach for monitoring OEE through statistical control procedures. The OEE/TEEP control chart is presented with sensitization procedures, allowing the user to adapt the results of the monitoring process to the needs of the monitored resource constraint. Performance results are presented based on an extensive Monte Carlo simulation study, with 4551 sets of 20 thousand observations each. One application example is also presented, for illustrating the potential of the proposed control charts.
