Comparison of Project Evaluation Using Cost-Benefit Analysis and Multi-Attribute Tradespace Exploration in the Transportation Domain

چکیده
The paper discusses the application of two decision methods, Cost-Benefit Analysis (CBA) and Multi-Attribute Tradespace Exploration (MATE), to the selection of “best” design alternatives across two case studies in the transportation domain. The cases are an airport express for the city of Chicago, and a freight rail line linking Lisbon, Portugal to Madrid, Spain. Through the joint use of MATE and CBA in project selection, shortcomings of CBA can be mitigated. Additional insight is gained with MATE through the ability to explore the distribution of project costs and benefits and related incentives for behavioral shifts, the keeping separate of different types of costs (for example, tangible and intangible), and the systematic exploration of a large number of designs early on in the process of conceptual design.

Classical Cost-Benefit Analysis (CBA) is a preferred method for the evaluation of large-scale infrastructure investment projects in the private and government sector. This paper proposes the use of a method for tradespace exploration as an iterative to classical CBA to help overcome some of its shortcomings.

One of the principal value propositions for the creation of Systems of Systems (SoS) is the ability to generate stakeholder value beyond that which can be delivered by a single system or even a collection of systems. The dynamic interactions among the component systems in a SoS make conceptual design decisions for SoS more complex compared to traditional system design. There are several heurist...

One of the primary challenges for decision makers during concept exploration in engineering system design is selecting designs that are valuable throughout the operational lifetime of the system. The problem is even more difficult when designing Systems of Systems (SoS), which are dynamic, complex, higher-order systems that may be composed of both legacy and new component systems. There are sev...

In this paper, we present a genetic algorithm (GA) for optimization of a multi-mode resource constrained time cost trade off (MRCTCT) problem. The proposed GA, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. Beyond earlier studies on time-cost trade-off problem, in MRCTCT problem, resource requirements of each execution mo...
