To analyze and monetize the effects associated with these uncertainties the real option valuation method was applied which is better equipped to incorporate uncertainty and determine the profitability of circular business model than traditional investment decisions metrics such as the net present valuation NPV method.
Results suggest that the NPV can significantly underestimate the value of circular business models; for example, the profitability for the recycling scenario was underestimated by a factor five using the NPV method. Furthermore, the risk premium was calculated as a means to quantify the implicit costs for companies associated with the vulnerability stemming from increasing and volatile resource prices. The risk premium corresponds to the value by which circular end-of-life strategies mitigate the potential impact of rising and volatile resource prices. Outcomes suggest that applying circular business models in the form of smarter end-of-life scenarios for the production and refurbishment of lamps may recover value over the production lifecycle.

The difference in nature of the two ensembles is clear from the two panels. The error decreases from a median value of For reference, the square represents the ideal point corresponding to an independent and identically distributed models i.
If the models are i. It reflects the independent development of global and regional models. The change in accuracy is generally smaller since the optimal single-scale pool contains models with not very different errors. The same holds for the distributions they passed the Kolmogorov-Smirnov test.
Opportunity Culture Impact
The mmeS-GR generally improves the indices compared to mmeS-R, even though global models are included. Like before, the improvements are seen in all datasets, despite their temporal aggregation. From the picture we see that, regardless of the treatment, the ensemble data capture the ozone power spectrum with no notable deviation from the measured spectrum from one another. It is important to note that an ensemble treatment is a purely statistical treatment that does not consider any physics constraints.
The deficiencies that were originally present in the individual model spectra are still present in the ensemble results, particularly the large power deficit in the range from 0. The analysis presented above gives us clear indications that the combination of the two sets of models analysed produces an improvement in the ensemble performance.
In particular, the hybrid ensemble appears to be superior to any single-scale ensemble in the optimum setting. For example, given six global, six regional, and three global and three regional ensembles, the optimization always favours the hybrid ensemble. This was repeated for all examined cases: the annual hourly records, the JJA hourly records and the annual daily maximum records.
Some important considerations need to be taken into account at this point. It is difficult to find quantitative evidence for the fact that the hybrid ensemble improvement can be unequivocally attributed to the multi-scale nature of the ensemble. We have no evidence, nor guarantee, that the same kind of improvement could be reached by adding more regional-scale models to the regional-scale ensemble, or more global models to the global-scale ensemble.
However, what is a clear conclusion is that the regional-scale ensemble is characterized by a higher level of redundancy in the members than the global ensemble, since fewer than half of the members produced the optimal ensemble, and that the use of the three best members from the regional-scale ensemble and three best global-scale models produces an improvement in the ensemble performance.
