In this paper, we investigate the design of such a GRSC with a special emphasis on three aspects; (1) uncertainty of waste collection levels, (2) associated carbon emissions, and (3) challenges posed by the supply chain's global aspect, particularly the maritime transportation costs and currency exchange rates.
Improving the understanding of subsurface systems and thus reducing prediction uncertainty requires collection of data.
However, mapping introduces additional uncertainty and collection of primary data with the preferred utility instrument is preferable.
On the basis of previous simulation studies and empirical data and given the potential limitations and uncertainty of assumptions of partial-collection designs, the case control design is the optimal choice versus partial-collection designs.
The proposed methodology can also be applied to problems such as estimation of predictive uncertainty, optimization of data collection strategies, and design of monitoring networks.
Although measuring chemicals in complex biological matrices is analytically possible (Needham et al. 2005), because of potential uncertainties during collection, interpreting the concentrations of biomarkers in matrices with relatively high potential for cross-contamination should be conducted cautiously.
A combination of collection of monitored data, mathematical modeling, sensitivity, and uncertainty analysis has been done using the QUAL2Kw, a river quality model.
An ensemble is the representation of the rainfall field and its uncertainty through a collection of possible alternative rainfall fields, produced according to the observed errors, their spatial characteristics, and their probability distribution.
The breeding year 1989 was not considered due to the high uncertainty in the collection of the data [16], [17].
Barriers were i) the large amount of time it took to organise participants for the study, especially over weekends when regional leaders were not always available on campus; ii) uncertainty about the collection of the questionnaires: some participants did not want to put sealed envelopes containing completed questionnaires in the boxes in 'public places' like the university library.
