A Portfolio Decision Analysis Study for Improving Consequence of Facility Failure Indices

The United States Air Force partially integrated the Mission Dependency Index (MDI) into its portfolio project selection model by assigning an MDI value to a facility type or real property category code (CATCODE) in lieu of assigning a unique MDI value to each facility through a structured interview process. This took an initial step to improve the Air Forces asset management practices; however, it failed to accurately capture the consequence of facility failure in some cases. Although a process to adjudicate the MDI value of individual facilities was created, it is still unknown how much the surveyed MDI value deviates from the CATCODE assigned MDI value and how this influences the Air Forces annual project portfolio selection model. The purpose of this research effort is to measure the deviation in MDI values produced from surveys and the adjudication process with the CATCODE assigned MDI values. It also uses a deterministic approach to portfolio decision analysis to determine the influence these surveyed and adjudicated MDI values have on the Air Forces project portfolio selection model. This research effort serves to provide insight to the Air Force Installation Mission Support Center and the Air Force Civil Engineer Center of the value and utility of surveyed and adjudicated MDI information when compared to their CATCODE assigned counterparts

System Dynamics Models for the Valuation of Real Options in Infrastructure Investments

As public utilities and government owners face increased budget constraints and greater expectations, alternative project delivery methods will increasingly be used to fast track projects, reduce costs, promote innovation and ensure proper performance for various types of facilities and infrastructure systems. The goals of public utility owners along with economic and financial considerations suggest why some project delivery methods have been selected over other project delivery methods. In response, the first phase of this doctoral research presents a model for selecting the optimum project delivery method that considers economic sustainability as well as other goals of multiple project stakeholders. This first phase of research contributes to the existing body of knowledge and benefits industry practitioners by identifying best practices that improve the project delivery selection process while enhancing risk mitigation efforts. The procurement selection process uses multiple-criteria decision-making and financial risk analysis to select the most economically sustainable delivery method given each project’s unique characteristics. A present value analysis establishes a range of values that considers variables that will potentially impact lifecycle costs. The selection of the procurement process is based on best value where financial risks to the concerned government and other project stakeholders are mitigated through service fee agreements and project finance structures, which are both dynamic and provide for real options. The second phase of this research presents an innovative approach for the valuation of the types of real options on project finance structures which are specifically procured through a design-build-finance-operate project delivery method (also known as a public-private partnership) (P3). This second phase of research includes an investigation into systems engineering and System Dynamics (SD) simulation modeling. An SD model is used for the valuation of real options attached to a P3 project’s finance structure. The valuation of these real options is based on the simulation results related to infrastructure performance. The significance of this research is made greater considering that P3s are increasingly being pursued because of their ability to alleviate pressure on government budgets, promote innovation and implement new technologies. These types of contracts, however, tend to be long-term and often need to account for future yet-to-be-seen variables that potentially impact the feasibility of this procurement method. This is especially true when the P3 project exists within a portfolio of competing assets across infrastructure systems. This second phase of research presents An SD model that is used to analyze the complexity of an infrastructure asset procured through a P3 within such a portfolio. An illustrative case demonstrates how discrete and continuous events potentially impact the successful procurement of infrastructure within a portfolio of competing assets comprising a regional transportation system. This second phase of research contributes to the existing body of knowledge by demonstrating how An SD model can simulate the real-world causal relationships that impact the procurement of infrastructure through P3s. The SD model is used for the valuation of real options to promote public initiatives, encourage private participation and enhance economic sustainability of P3 as a viable procurement strategy. The third and final phase of this doctoral research considers the increasing complexity of infrastructure procurement as individual assets are increasingly viewed as being part of a larger network of interdependent systems. In response, the objective of this final phase is to present a methodology to simulate the behavior of assets that span across different types of infrastructure systems. This investigation presents a method for analyzing investments that traverses across different infrastructure systems with individual assets procured through a variety of project delivery methods. This third investigation also utilizes An SD simulation model. In the final phase of this doctoral research, however, the SD model captures the causal relationships between competing assets where simulation results elucidate the compounding effects of multiple investments that traverse across two or more infrastructure systems. By doing so, this research contributes to the existing body of knowledge and demonstrates how SD models are effectively used to value real options that are termed exotic. These exotic types of real options occur within a portfolio of competing infrastructure assets where the valuation of each real option must consider the compounding effects of competing alternatives as well as the value of the underlying asset. This research presents a methodology for the valuation of multiple types of exotic options in real investments that traverse across various types of infrastructure systems. This method can also be applied to the valuation of other types of exotic options in various industries including research and development pursuits

Case: Peatland Selection

The importance of environmental decision making is growing. Private companies and public organizations are facing decisions involving multiple objectives. In particular, focusing solely on financial objectives is no longer enough but taking into account the environmental, social and political objectives is needed. The methods used to solve these environmental problems have been based on heuristic approaches. However, these methods lack the capability to provide optimal solutions as most of the environmental decisions are portfolio selection problems. Robust Portfolio Modeling (RPM) is a decision analysis method that combines mathematical optimization in portfolio selection to incomplete preference information. This incomplete information is common in environmental decision making which includes multiple stakeholders with conflicting views. However, RPM has not been applied before to real-life environmental cases. This thesis will first explore the characteristics of environmental decision making, secondly go through different methods used in environmental decision making and finally apply RPM methodology into peatland selection case. The results of RPM are then compared to the results of the heuristic YODA method previously used in the same peatland selection case. Results indicate that RPM and YODA select highly different type of peatlands. RPM takes better into account the cumulative effects related to portfolio selection than YODA. Therefore, it is argued that RPM might be suitable for environmental decision making

Proposing a Hybrid Approach to Predict, Schedule and Select the Most Robust Project Portfolio under Uncertainty

Suitable project portfolio selection in inconsistent economy that can reduce the portfolio risks and increasing utilities for investors has gained significant research attentions.   This article addresses the project portfolio selection in which conventional certain (1) prediction, (2) optimization and (3) clustering approaches cannot be used to face uncertainty. To predict the real value of affecting project risk parameters, neural network has been used; Then to determine the optimized sequences and procedures, the proposed model have been evaluated using the multi-objective shuffle frog leaping algorithm (SFLA) by robust optimization approach; To suggest different risk criteria, K-means algorithm utilized to categorize the candidate projects and differentiating the clusters.  As the proposed hybrid methodology is studied on 420 different construction projects in an Iranian construction company in two economic stable years and an instable year in Iran real estate market. The results show 96 percent prediction-optimization capability due to different desired criteria

A risk mitigation framework for construction / asset management of real estate and infrastructure projects

The increasing demand on residential, office, retail, and services buildings as well as hotels and recreation has been encouraging investors from both private and public sectors to develop new communities and cities to meet the mixed demand in one location. These projects are huge in size, include several diversified functions, and are usually implemented over many years. The real estate projects’ master schedules are usually initiated at an early stage of development. The decision to start investing in infrastructure systems, that can ultimately serve fully occupied community or city, is usually taken during the early development stage. This applies to all services such as water, electricity, sewage, telecom, natural gas, roads, urban landscape and cooling and heating. Following the feasibility phase and its generated implementation schedule, the construction of the infrastructure system starts together with a number of real estate projects of different portfolios (retail, residential, commercial,…etc.). The development of the remaining real estate projects continues parallel to customer occupancy of the completed projects. The occurrence of unforeseen risk events, post completing the construction of infrastructure system, may force decision makers to react by relaxing the implementation of the remaining unconstructed projects within their developed communities. This occurs through postponing the unconstructed project and keeping the original feasibility-based sequence of projects unchanged. Decision makers may also change the sequence of implementing their projects where they may prioritize either certain portfolio or location zone above the other, depending on changes in the market demand conditions. The change may adversely impact the original planned profit in the original feasibility. The profit may be generated from either real estate portfolios and/or their serving Infrastructure system. The negative impact may occur due to possible delayed occupancy of the completed real estate projects which in turn reduces the services demand. This finally results in underutilization of the early implemented Infrastructure system. This research aims at developing a dynamic decision support prototype system to quantify impacts of unforeseen risks on the profitability of real estate projects as well as its infrastructure system in the cases of changing projects’ implementation schedules. It is also aimed to support decision makers with scheduled portfolio mix that maximizes their Expected Gross Profit (EGP) of real estate projects and their infrastructure system. The provided schedules can be either based on location zone or portfolio type to meet certain marketing conditions or even to respect certain relations between neighbor projects’ implementation constraints. In order to achieve the research objectives, a Risk Impact Mitigation (RIM) decision support system is developed. RIM consists mainly of four models, Real Estate Scheduling Optimization Model RESOM, Sustainable Landscape Optimization Model SLOM, District Cooling Optimization Model DCOM and Water Simulation Optimization Model WSOM. Integrated with the three Infrastructure specialized models SLOM, DCOM, WSOM, RESOM provides EGP values for individual Infrastructure systems. The three infrastructure models provide the demand profile that relate to a RESOM generated implementation schedule. RESOM then uses these profiles for calculating the profits using the projects’ capital expenditure and financial expenses. The three models included in this research (SLOM, DCOM and WSOM) relate to the urban landscape, district cooling and water systems respectively. RIM is applied on a large scale real estate development in Egypt. The development was subjected to difficult political and financial circumstances that were not forecasted while preparing original feasibility studies. RIM is validated using a questionnaire process. The questionnaire is distributed to 31 experts of different academic and professional background. RIM’s models provided expected results for different real life cases tested by experts as part of the validation process. The validation process indicated that RIM’s results are consistent, in compliance with expected results and is extremely useful and novel in supporting real estate decision makers in mitigating risk impacts on their profits. The validation process also indicated promising benefits and potential need for developed commercial version for future application within the industry

Infrastructure Asset Management Modeling through an Analysis of the Air Force Strategic Vision and Goals

Effective asset management requires an overarching model that establishes a framework for decision-makers. This research project develops a strategic level asset management model for varying types of infrastructure that provides guidance for effective asset management. The strategic model also incorporates Next Generation Information Technology initiatives into a single coherent system to streamline the top-down, bottom-up flow of information. The strategic model is applicable to agencies with a large, varying infrastructure inventory and limited resources. This research also develops an improved performance modeling tool, a critical component of the strategic model. This tool objectively prioritizes maintenance and repair projects according to measurable metrics as well as the strategic vision, established goals, and policies. Asset management of Air Force infrastructure provides an example of applicability for this strategic model and improved tool; thus, an asset management example of Air Force infrastructure is utilized throughout the research project to demonstrate the utility of the model and the tool. The strategic level model and improved tool enable policy-makers to make decisions that tie goals, infrastructure inventory, condition state, importance and criticality, and budget constraints to system performance. As a result, insight is gained on ways to maximize efficiency and optimize the performance of infrastructure
