“…Further supporting this argument is related literature found from cost-benefit analysis in weighing whether to use the cost-benefit difference or the cost-benefit ratio as the criterion to rank the value of a program. In the case of limited resources, it is generally agreed that the ratio, not the difference, should be used for ranking purpose (Dompere, 2004 andDrummond et al, 2005). To identify services with high p/c ratios, without access to a detailed costing study, one must resort to the literature.…”

Global budget payment is one of the most effective strategies for cost containment, but its impacts on provider behavior have not been explored in detail. This study examines the theoretical and empirical role of global budget payment on provider behavior. The study proposes that global budget payment with price adjustment is a form of common-pool resources. A two-product game theoretic model is derived, and simulations demonstrate that hospitals are expected to expand service volumes, with an emphasis on products with higher price–marginal cost ratios. Next, the study examines the early effects of Taiwan’s global budget payment system using a difference-in-difference strategy and finds that Taiwanese hospitals exhibited such behavior, where the pursuit of individual interests led to an increase in treatment intensities. Furthermore, hospitals significantly increased inpatient service volume for regional hospitals and medical centers. In contrast, local hospitals, particularly for those without teaching status designation, faced a negative impact on service volume, as larger hospitals were better positioned to induce demand and pulled volume away from their smaller counterparts through more profitable services and products such as radiology and pharmaceuticals.

“…The confidence intervals are interpreted as being "low," "medium," and "high" and quantitative measures of these linguistic variables are to be determined based on the characteristics of the project to which the analysis is being applied. The assumption of triangular fuzzy numbers in similar applications can be found in Teodorovic and Vukadinovic (1998) and Dompere (2004).…”

“…Thus, the above is a class of multi-benefits attributable to multifactors. Such a case is well described by Dompere (2004). Dompere shows that benefits realized through multifactors can be expressed linearly and are additive.…”

“…(2) By converting both benefits and costs in fuzzy form we can be assured that we are comparing apples to apples; thus, the resulting B/C ratio might make more sense because fuzzy representation of a quantity always lies between 0 and 1. Our extensive literature review found very limited applications (Neitzel and Hoffman, 1980;Kahraman, 2001;Dompere, 2004) of fuzzy logic in benefit cost assessment. Neitzel and Hoffman (1980) described benefits and costs in linguistic rather than numerical terms.…”

Feasibility of Computer Visualization in Highway Development: A Fuzzy Logic-Based Approach

Building transportation infrastructure requires careful planning and design with due consideration to land and environmental impacts. Imprecise assessments of detailed design requirements, and land and environmental impacts lead to frequent scope changes of transportation infrastructure improvement projects. Computer visualization (CV) and geographic information systems (GIS) can greatly assist in understanding the detailed design requirements as well as land and environmental impacts. However, the application of CV is quite limited in transportation primarily because of the limited knowledge of its benefits over cost. This study investigates the feasibility of CV in modeling highway improvement sections. Two potential benefits are realized through the proposed modeling: (1) better representation of future improvements resulting in enhanced public and political support and (2) early identification of adverse environmental and land impacts as well as detail design requirements resulting in fewer scope changes. A fuzzy logic-based general approach is proposed to calculate the expected benefits of CV. A computer code called the Projection Option Processor (POP) is developed in Microstation's BASIClanguage to automate repetitive tasks in the visualization procedure. Two real highway projects from Maryland are visualized and the benefits and costs of the visualization are estimated using the proposed fuzzy logic-based approach. The results indicate that using POP is costeffective resulting in higher benefit-cost ratios (B/C). Increasing the number of views, alternatives, and reevaluations for visualization may increase the total visualization cost significantly.
