This book was released on 2011 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision making is a cognitive process which includes attention, remembering, understanding, and solving. In every industry decisions are required at every step along the way. Available information should be analyzed or if information is not available it should be gathered first to come up with a decision. A predefined decision-making process helps in making informed decisions along with maintaining consistency in the decision made. Contiguous parameters to a specific application are required along with an ideal mathematical model for informed decision-making. A potential management which requires an optimal decision-making is bridge construction industry due to the fact that, the bridges not only connect communities making commute shorter and faster but also shape our lives through urban development. The need for bridge rehabilitation/replacement engenders bottlenecks and closures on existing freeways which creates outrageous conditions for travelling public. Thus, the demand of travelling public for deploying bridge rehabilitation/ replacement process using innovative construction processes evolved in Accelerated Bridge Construction (ABC). Various state departments of transportation have developed decision-making models to identify if ABC is a viable option for a site, yet the deficiencies pertaining in those models require contemplation. The herein study identifies the bridge construction contiguous parameters and models to precisely address the deficiencies in the existing decision-making models for bridges. The outcome of this study is an informed decision-making model that can be customized using site specific data in selecting an optimal bridge construction process. A decision-making tool is developed for implementation of the decision-making model. The tool os demonstrated through a case study of Parkview Bridge over US 131 in Kalamazoo, MI.

Download or read book Available Accelerated Bridge Construction Options for Short Span Bridges written by Armin Mehrabi and published by Cambridge Scholars Publishing. This book was released on 2024-03-18 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: By employing prefabricated bridge elements and systems, Accelerated Bridge Construction reduces on-site construction time and traffic disruptions, and enhances long-term performance. ABC is particularly advantageous for short-span bridges that are well-suited to standardized prefabrication. In such cases, the entire superstructure and substructure can often be constructed using prefabricated deck elements, modular decks, or systems that span the full bridge width. The construction methods can range from traditional crane installations to Self-Propelled Modular Transport units or slide-in techniques for moving the entire superstructures. This book introduces the concept of ABC and examines its application in the context of short-span bridge construction. It categorizes and details short-span bridges based on various criteria and evaluates the performance of the existing bridges. Decision-making processes regarding the adoption of ABC, choice of elements, systems, and construction methods are also discussed. Additionally, the book covers the inspection of short-span bridges and includes a design example.

Download or read book Agent based Modeling of ABC Methods for Decision making in Highway Bridge Projects Including Uncertainty and Several Stakeholders written by Abdul Wahed Mohammed and published by . This book was released on 2016 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accelerated Bridge Construction (ABC) methods that were recently introduced in the U.S. to reduce the on-site construction duration furnish several benefits to the public and highway agencies. Further, the traffic growth in addition to increasing number of functionally obsolete and structurally deficient bridges necessitates the increased implementation of ABC methods. In recent years, several Departments of Transportation (DOTs) in the U.S. have developed decision-making models to compare broadly ABC to conventional bridge construction for a particular site. However, with increased implementation and advancements in ABC methods, there is a need for specifying a particular ABC method and a superstructure system for a site by means of evaluating the associated uncertainty. The uncertainty arises because of the activities associated with ABC methods, and constructibility and durability of superstructure systems with respect to site-specific conditions. Moreover, the interactions among the internal stakeholders such as the DOT, Designer, Contractors, Consultants, etc., while delivering a project using an ABC method contribute to the uncertainty. Understanding the need, a decision-making model is required that enables the evaluation of ABC methods and the associated superstructure systems in order to achieve optimal constructibility and durability of a bridge. The agent-based complex systems approach enables modeling and simulating the activities and stakeholder interactions in order to evaluate the impact of the uncertainty on the ABC project performance. The uncertainty can be quantified by identifying the parameters that contribute to uncertainty, and establishing parameter correlations with the site-specific data. The following outline the specific tasks performed during the research: (1) Documenting potential superstructure systems that can be used with the ABC methods for a particular region, (2) Documenting major activities and internal stakeholders of ABC methods, (3) Documenting parameters that contribute to uncertainty of the activities, (4) Developing the parameter correlations with site-specific data for a particular region, (5) Formulating the decision-making framework and demonstrating the framework using an example, and (6) Developing recommendations for future research to extend the framework to an automated decision-making model/tool.

Book excerpt: The National Bridge Inventory shows that more than 480,000 bridges that serve the U.S highways are of a median age of more than 42 years and a design life of 50 years; out of which, approximately 14 and 16 percent of the bridge inventory falls into the functional and structural deficient categories, respectively. In a mature infrastructure system, upgrade, repair, or replacement requires either restriction or closure of those parts of the system. Traffic disruption during maintenance and construction activities frequently results in disruptions to local economies and communities; and raises issues of safety and congestion. The use of traditional technologies and techniques for infrastructure rehabilitation are not effective enough to mitigate these disruptive effects of rehabilitation work. A systems approach to accelerating infrastructure construction is required to mitigate the impact of the extensive rehabilitation activities that are likely to take place in immediate future. The decision making system proposed in this report uses Analytical Hierarchy Process and provides the decision maker with a tool to quantify the qualitative trade-offs between various objectives to extract a single set of weights which reflect the level of importance of each of the factors in the overall decision making process. This system will thus provide the decision makers an excellent and transparent tool to make decisions regarding choosing an optimal holistic strategy for decision making.
