Book Description
Resource allocation mechanisms have become a major issue for transportation agencies in the United States and around the world. For this reason, transportation agencies are exploring alternatives to modify traditional allocation mechanism due to budgetary challenges generated by the decrease in funding and the increasing cost of preserving and operating transportation systems. Transportation asset management (TAM) practices enable agencies to change the operation and management of transportation infrastructure from the traditional concept of “public-owned” systems to more business-oriented processes. One of the main concerns with the TAM framework and its implementation is the absence of an organized process for cross-asset resource allocations. Additionally, most of the alternative methods for funding allocations focus on maximizing infrastructure performance under budget constraints, but ignore the consideration of equity or fairness. The objective of this study is to develop an innovative methodological framework for cross-asset resource allocations, yielding a data-oriented approach to enhancing infrastructure management. The allocation module is comprised of three resource allocation mechanisms following a top-down approach: a fair division approach based on asset performance, a performance-based multi-objective optimization, and an asset value-based multi-objective optimization. In the first mechanism, the fair division method is used to allocate resources in such a way that all parties involved believe they are receiving a fair share of the available resource based on established utility functions. Then, Collective Utility Functions (CUFs) are employed to perform the resource allocation, which results in total utility and total envy values. These values are used to conduct trade-off analyses of the different allocations based on the CUFs. Under the second procedure, a multi-objective optimization formulation is employed to integrate efficiency and equity, where equity is taken into consideration by using utility and envy concepts, while efficiency is incorporated by maximizing performance. In the third mechanism, an innovative asset value methodology is integrated into the cross-asset resource allocation process, serving as a common comparative measure between assets. To demonstrate the applicability of the proposed methodological framework, a case study was conducted using two asset groups, pavements and bridges, from the roadway network of the Austin District located in Texas. Results from the case study shows that the proposed methodological framework has great potential as a tool to support highway agencies in performing cross-asset resource allocations at the network level.

Book Description
This proceedings volume chronicles the papers presented at the 35th CIB W78 2018 Conference: IT in Design, Construction, and Management, held in Chicago, IL, USA, in October 2018. The theme of the conference focused on fostering, encouraging, and promoting research and development in the application of integrated information technology (IT) throughout the life-cycle of the design, construction, and occupancy of buildings and related facilities. The CIB – International Council for Research and Innovation in Building Construction – was established in 1953 as an association whose objectives were to stimulate and facilitate international cooperation and information exchange between governmental research institutes in the building and construction sector, with an emphasis on those institutes engaged in technical fields of research. The conference brought together more than 200 scholars from 40 countries, who presented the innovative concepts and methods featured in this collection of papers.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 736: Resource Allocation Logic Framework to Meet Highway Asset Preservation presents a logic framework for allocating limited highway asset preservation funds among competing demands in order to help maximize system performance. The report also presents a spreadsheet-based computational tool that implements the framework. Prototypical application scenarios and case-study examples illustrate how transportation agency staff may use the framework to assist resource allocation decision making"--Publication information.

Book Description
Asset valuation is an essential component of effective asset management. It is an important method to demonstrate proper management of public assets and effective utilization of government's budgets. Several government regulatory bodies mandate agencies to report their Tangible Capital Assets' (TCA) values within their annual statement. For example, the Canadian Public Sector Accounting Board (PSAB), the Governmental Accounting Standard Board (GASB) and the New Zealand International Financial Reporting Standards (NZ IFRS), to name a few. Although some limited research has been conducted on incorporating asset value into asset management systems, there is no comprehensive work done to date to incorporate asset valuation in asset management. An integration method is imperative to manage assets in the most optimized cost-effective ways while maintaining or enhancing the value of these assets. Integrating asset value in asset management strengthens the asset management framework by integrating financial and engineering reporting. In addition, agencies have traditionally made investment decisions for individual assets separately. Independent management systems have traditionally been developed to manage assets, in particular pavements and bridges, the two main transportation assets. The lack of integration between management systems may be due to restrictions associated with funding and/or limitations to the agency's ability to compare data objectively across asset types. Deciding how to best allocate limited resources across these various asset classes to provide acceptable performance poses a persistent and difficult challenge for agencies. Asset value holds a great promise to be incorporated in asset management as a performance measure that translates infrastructure condition in monetary terms that can be easily communicated and understood by the stakeholders (agency, policy makers, users, etc.). Therefore, asset value can be viewed as a common performance measure for integration mechanism between competing asset management systems. vi The objective of this research is to develop a methodology that integrates asset value as a performance measure in asset management decision making. This thesis introduces an asset management methodology that aims to arrive at an optimum value-based asset management plan of maintaining infrastructure assets taking into account budgetary and performance constraints. To achieve this objective, an Asset Value Index (AVI) that integrates asset value and value-driver performance measures and associated thresholds and Level of Service (LOS) requirements is proposed. The Multi-Attribute Utility Theory (MAUT) is used to develop the proposed AVI. In order to incorporate asset value in asset management and develop the AVI, a comprehensive and analytical analysis of various asset valuation methods is conducted. Based on the analysis, challenges of incorporating asset management are identified and addressed by the proposed Asset Value Loss ratio (AVL) as an integration means. To demonstrate the proposed methodology, a case study from the Ministry of Transportation of Ontario (MTO) second generation Pavement Management System (PMS2) is presented. An overview of MTO road assets network is presented and analyzed. In addition, the various components of the proposed methodology are demonstrated through the case study. Furthermore, the outcome of the implementation of the proposed AVI is compared to optimization output, Do-Nothing output as well as needs assessment output. Furthermore, building on the proposed methodology presented, a value-based cross asset management methodology is presented using the AVI as a common integration measure. A case study of pavements and bridges based on data obtained from the 7th International Conference of Managing Pavement Assets (ICMPA 7) is used to illustrate the proposed methodology.
