Requirements for a project evaluation and selection methodology

The evaluation and selection of projects is usually referred as critical for the sustainability of the competiveness of organizations, but also as a complex process. If, on one hand, a formal and structured selection process may contribute to the clear communication of objectives and transparency, on the other hand, it may be shrouded with incomplete information and uncertainty about the real potential contribution of projects. The design and development of project selection methodologies should inevitably take into consideration organizational characteristics and constraints. Literature has provided various contributions to this topic, however, their emphasis have been on one or few requirements. This paper presents a review of the requirements for developing and implementing a project evaluation and selection methodology in organizations. This overview can support managers in fine tuning project selection practices in organizations.info:eu-repo/semantics/publishedVersio

A Multi-Objective Decision-Making Model for Resources Allocation in Humanitarian Relief

This thesis addresses the critical resource allocation in the initial days of a disaster relief operation. One of the most important and essential components of relief operations is the allocation of scarce resources to accomplish the relief efforts. Every operation for disaster relief needs various critical resources whether they are personnel, equipment, supplies, or simply finances. Several research efforts for disaster relief have suggested methods to allocate scarce resources across a variety of competing objectives and programs in a disaster relief operation. Many of those efforts focused on optimizing a mathematical programming model subject to budget constraints. However, capturing the values of the decision-maker(s) in such a model is relatively under explored. The lack of clear organizational values contributes to the inconsistency in practice and hinders effective resources allocation across the disaster relief system. The purpose of this study is to develop a multi-objective decision-making (MODM) model to incorporate the decision-maker(s) value trade-offs in the disaster relief resources allocation problem. The notional model is based on a hurricane and flood scenario and the decision window for the resource allocation is the critical first 72 hours after the initial damage assessment has been made. The value focused thinking (VFT) process is used to capture the value trade-offs and the resulting value hierarchy is optimized via a mathematical programming model to solve the multi-objective resource allocation problem

A Multiple-Objective Decision Analysis of Stakeholder Values to Identify Watershed Improvement Needs

The paper describes the use of multiple objective decision analysis to qualitatively and quantitatively assess the quality of an endangered watershed and guide future efforts to improve the quality of the watershed. The Upham Brook watershed is an urban watershed that lies at the interface of declining inner city Richmond, Virginia and growth-oriented Henrico County. A section of stream within the watershed has been identified as so dangerously polluted that it threatens the health of the residents who live within the watershed boundaries. With funding provided by the National Science Foundation, the Upham Brook watershed project committee was formed to address the quality of the Upham Brook watershed; it consisted of experts from multiple disciplines: stream ecology, environmental policy, water policy, ground and surface water hydrology and quality, aquatic biology, political science, sociology, citizen participation, community interaction, psychology, and decision and risk analysis. Each members\u27 values and goals were brought together using a watershed management framework to meet the overall objective of the committee: to maximize the quality of the Upham Brook watershed. The resulting model was used to identify the largest value gaps and to identify future programs needed to improve the quality of the watershed

Grasping complexity: analysing risk for sustainable development

Sustainable development relies on our ability to make decisions today that will determine our tomorrow. Given that uncertainty is explicitly allowed to influence our view of what the future holds for us, most ex ante analyses of challenges for sustainable development can be viewed as analysing risk. Many frameworks for analysing risk exist today, but analysing risk for sustainable development entails different requirements. By applying a combination of traditional science and design science, this thesis presents six such requirements, informed by available theory and new empirical studies. The thesis also presents six criteria for scientifically developing frameworks for analysing risk for sustainable development

Methodology for Value-Driven Enterprise Architecture Development Goals: Application to DoDAF Framework

The Department of Defense Architectural Framework (DoDAF) describes 29 distinct views but offers limited guidance on view selection to meet system needs. This research extends the Value-Driven Enterprise Architecture Score (VDEA-Score) from a descriptive, evaluation protocol toward a prescriptive one by evaluating each DoDAF view and its contribution to the overall objective of the completed architecture. This extension of VDEA is referred to as VDEA-Development Goals (VDEA-DG). The program manager or other decision-makers may use this insight to justify the allocation of resources to the development of specific architecture views considered to provide maximum value. This research provides insight into the Joint Capabilities Integration and Development System (JCIDS) process and policy requirements. Existing guidance of a static list of views prior to DoD milestone approval detracts from the creation of vital architecture for system success. This research shows overlap between the most important views for the considered architecture project and the JCIDS requirements and identifies areas for JCIDS policy improvement. This research also identifies areas where DoDAF does not directly support the creation of capabilities. With additional information on the resources required for creating individual views, the tool could be expanded to identify an optimal build sequence given resource constraints

Digitised engineering knowledge for prefabricated façades

Façade design is a multidisciplinary activity requiring the balancing of many conflicting design requirements. Very often, however, the designed façade does not respond to these requirement, as relevant design and manufacturing knowledge, normally originating downstream in the design process, is not properly used upstream in the process. The inability to respond to this challenge increases the environmental impact of the construction sector, which is currently covering nearly 40% of the global emissions. Also, improving the stagnant sector’s productivity is of paramount importance today, as it is deemed to be nearly as half as that of the manufacturing sector. This research has thus investigated ways to collect, store, represent and digitalise the engineering knowledge that underpins the design of façade products for façades that are better designed. The work has involved a close collaboration with the British general contractor (and façade manufacturer) Laing O’Rourke. The research has explored ways of using design and manufacturing knowledge and it has developed a digital tool and tested its functionalities. In the first part, after a review of the state-of-the-art in knowledge-based approaches in other fields, the digital tool, and relevant methodology, are developed. The tool informs the user about the expected performance and manufacturability of the façade product under analysis. The boundaries of traditional research were also pushed beyond the proof-of-concept by validating the digital tool in both simulated and real-world scenarios. The goal was to understand how people can develop a design solution while being supported by a digital tool. It was found that using such tool increases the user’s awareness about the consequences of the his/her choices in less time. In the last part of the research, the tool was used to develop a novel optimisation algorithm, by including considerations about aesthetics and manufacturability, in parallel with the traditional performance-based approach. The application of the algorithm to a case study has shown that it is possible to improve existing solutions in terms of performance, without affecting aesthetic and manufacturability significantly.EPSRC, Laing O'Rourk

Modeling Homeland Security: A Value Focused Thinking Approach

The events of September 11, 2001 have propelled the topic of homeland security to the forefront of national concern. The threat of terrorism within the United States has reached an unprecedented level. The pervasive vulnerabilities of the nation\u27s critical infrastructure coupled with the destructive capabilities and deadly intentions of modern terrorists pose extraordinary risks. The United States must mitigate these risks while at the same time balancing the associated costs and impact on civil liberties. Currently, the United States lacks effective methods and measure for assessing the security of the homeland from acts of terrorism. This study outlines a first cut decision analysis methodology for identifying and structuring key homeland security objectives and facilitating the measurement of the United States\u27 capability to execute these objectives
