Sensitivity Analysis (SA) investigates how the variation in the output of a numerical model can be attributed to variations of its input factors. The reference flow is and the carbon dioxide emission is 32164.06g. Compared with the original design, the carbon dioxide emission is reduced by 5.02. Firstly, the computation model of LCA is discussed to find out the proper way to combine the LCA with parametric model. J. Wang, X. Chen, J. Li, and Z. Lv, Developing indoor air quality through healthcare and sustainable parametric method, in Proceedings of the 4th International Conference on Bioinformatics and Biomedical Engineering (iCBBE '10), June 2010. It is a tool to assess the potential environmental impacts and resources used throughout a products life cycle, that is, from raw material extraction, via manufacturing, transportation, and use phases, to EOL [7]. V.Gupta. The parameters relevant to healthcare and sustainability are derived from the database of BIM. In general, sensitivity analysis is used in a wide range of fields, ranging from biology and geography to economics and engineering. However, current metagenomic workflows produce data that suffer from low sensitivity and an inability to accurately reconstruct partial or full genomes, particularly those in low abundance.

George M. Hornberger,[3] Keith Beven[4] and Robert C. Moreover, parametric design model cannot assess the products environmental impacts since it only focuses on the relationship between mass of materials/energies and design parameters. On the other hand, companies have a strong will to make environmentally friendly product in order to meet customer and market requirements and thus to earn more benefits. All the aforementioned methods are not focused on the parameter design and cannot identify which parameters need to be chosen to improve the environmental performance. It also recognizes that complexity is still part of the model make-up because of the difficulty in assessing the behavior and interaction of a number of the input parameters.

Therefore, environment-oriented design of PCB should be studied carefully. . Considering the gap between the increasing requirements of environmentally friendly products and the lack of environmental knowledge for the designers, the ecoparametric method is effective to fill the gap. 112, pp. Indeed, the design phase plays a crucial role in the reduction of products environmental impacts. Indeed, Siddhaye and Sheng only proposed an outline to combine the design parameters with environmental impact in their model; the detailed steps are not provided. However, the environmental impacts reduction is a complex issue. However, it has not reached the step of environmental assessment yet. 13, no. Softw., vol. PCCs quantify the strength of a linear relationship between input-output pairs after eliminating the linear influence of other input variables, and can be readily calculated from the input-input correlation matrix and the input-output correlation vector. Siddhaye and Sheng analyzed the PCB manufacturing processes and proposed a series of parametric models [11]. Meanwhile, the HHS only focuses on the health hazard. 3, pp. The recent plan for reinforcing resilience for New York City, following Hurricane Sandy and including coastal protection, transport and communications, was the result of models of climatic conditions and trends using sensitivity analysis.

How to help designers without much environmental knowledge to design an environmentally friendly product becomes a big challenge nowadays. The parametric design method is introduced into the design phase, also called ecoparametric design, and implemented in electronic and architecture industry already. The method proposed in this paper will help designers to quickly identify the key environmental performance factors among numerous design parameters without much environmental knowledge and thus make ecodesign more feasible in practice. Uncertainty and sensitivity analysis are an integral part of the modeling process (Saltelli et al., 2000). Section 2 describes the related works; Section 3s details introduce the proposed sensitivity analysis approach and then a case study is conducted in Section 4 to illustrate this approach. The key environmental performance factors which have significant influence on the products environmental impacts can be identified by analyzing the relationship between environmental impacts and the design parameters. To address this issue, the subsampling based ANOVA method are developed in this study, in which . in cases where a number of model-based inferences are similar but conditional on different assumptions, and for many other applications linked to the quality of models. On the basis of the integration, the analysis of which parameter has the most significant influence on environmental impacts becomes possible. Rogers, C. C. M., Beven, K. J., Morris, E.

In this case study, the carbon dioxide emission is used as an indicator to compare different effects of the different design solutions. Then, the designers can quickly identify the fact that the key environmental performance factor which has a significant influence on the carbon dioxide emission is the value of the area of PCB panel. Sampling. The manipulation of these methods implies that the user must be environmental experts who have sound knowledge on the related industrial sector. Rather than simply reporting outputs from a model, data scientists could implement sensitivity analyses to provide their executives or stakeholders with additional actionable information based on the influence of the specific inputs. Above all, they must be supported and assisted by selected solutions, for example, materials databases. By answering the questions in the checklist, several reference systems are generated for comparing with other solutions. Often, time influences many model processes.

However, this function cannot help users to find out the relationship between the mass of materials/energies using in each process and design parameters. In order to verify the results, the values of these five parameters are adjusted according to the design constraints and the carbon dioxide emission is recalculated. We assessed the time-dependence of parameter sensitivity in a well-established forest growth model 3-PG (Physiological Principles for . Defects 38%. denotes the total number of layers of the board, and is the area of the trimmed panel. Conversely, variables which do not show up as important per these metrics are either restricted to a small range in the probabilistic analysis, and/or are variables to which the model outcome does not have a high sensitivity.

He has master's degrees in Operations Research from University of California Irvine and Mathematics from Northeastern University. Global Sensitivity Analysis: The Primer | Wiley Complex mathematical and computational models are used in all areas of society and technology and yet model based science is increasingly contested or refuted, especially when models are applied to controversial themes in domains such as health, the environment or the economy. In the future, the relationship between a design parameter and different environmental releases will be investigated. In this paper we review the SA literature with the goal of providing: (i) a comprehensive view of SA approaches also in relation to other methodologies for model identification and application;. Engineering: Engineers test their designs and models through sensitivity analysis. For instance, if X = 3 (Cell B2) and Y = 7 (Cell B3), then Z = 3 2 + 7 2 = 58 (Cell B4) Z = 58. Sensitivity analysis, or the what-if analysis, is a tool used in financial modeling to evaluate how the effect of uncertainties in one or more input variables may lead to uncertainties in the output variables. This case study only observes the relationship between parameters with one environmental issue. Is authored by leading sensitivity analysis practitioners, combining a range of disciplinary backgrounds.

A sensitivity analysis approach based on LCA and ecodesign is proposed in this paper. The methodology is illustrated using an analytical model of environmental health risk arising from groundwater-borne ra-dionuclide migration from a nuclear waste repository. By assuming the relationship among the relevant economical flows (the term economic flows represents the materials/energy flows or commodity flows within the economic systems [9]) in LCI (life cycle inventory), the association between environmental impacts and design parameters is analyzed based on sensitivity analysis. We use global sensitivity analysis (specifically, Partial Rank Correlation Coefficients) to explore the roles of ecological and epidemiological processes in shaping the temporal dynamics of a parameterized SIR-type model of two host species and an environmentally transmitted pathogen. Softw., vol. Environmental parameters, depending on context, include wind, humidity, cloud cover, rainfall, currents, tides, temperatures and solar exposition. This paper is organized as follows. Many ecodesign methods have been proposed in the literature [27]. Sensitivity Analysis is used to know and ascertain the impact of a change in the outcome with the inputs' various projected changes.

Sensitivities and intolerances to foods and environmental compounds are on the increase and can cause varying amounts of distress to your body. The whole product life cycle can be defined by a series of unit processes which can be denoted by a matrix as shown in formula (1). Rearranging formula (3), the total scaling factors required to meet the total commodity net output can be calculated by, On the basis of the technology matrix, the intervention matrix, and the final demand vector, the total pollutant emissions and natural resources consumption by the system to produce a certain amount of commodity output are calculated by [15], In order to investigate the environmental effects due to the mass of materials/energies used in the system, Heijungs and Suh propose a sensitivity analysis method to calculate the influence of variation in matrix [9]. The transportation sector emits more CO 2 than any other industry. The manufacturing processes of PCB are complex. By refining the model and making it as robust as possible, energy and environmental trends can be calculated and mapped. In the context of probabilistic models, however, sensitivity analysis is generally taken to imply identification of input parameters that have the greatest influence on the spread (variance) of model results (Helton, 1993). It helps in identifying the key variables that are major influence in the cost and benefits of the project. 113129, Mar. Softw., vol. This paper describes the Partial Correlation Coefficient (PCC) concept for sensitivity analysis of probabilistic models with correlated inputs. On the basis of the new model, a sensitivity analysis approach is proposed to help users to find out the design parameter which has the most significant influence on the environmental performance of the product. Together with Earth sciences and Engineering, Environmental sciences have the largest number of academic articles including or dealing with sensitivity analysis.Environmental computer models are increasingly used in a wide variety of studies and applications.
