asks and Questions $(50$ points$)$: In this memo you should conduct a reliability and risk analysis of the reverse osmosis filter and the potential for planned maintenance, conduct and interpret a Monte Carlo analysis of the system to evaluate the benefits of an additional catalytic reactor, and complete a stakeholder analysis of potential ethically important risk mitigation priorities.

Conduct a availability analysis of the Reverse Osmosis Filter including an assessment of the relevant failure modes and their effects. For this analysis, consider availability to be represented by the following expression:

Your analysis should account for the uncertainty in the Weibull parameters and the time to repair information. Consider which filter model would be better on average as well as how likely your selected model is to be better than the alternative. The failure and repair data for the filters can be accessed here Download here. From this you can determine the relevant Weibull parameters, confidence intervals, and predict reliability and availability as a function of time $($here$,$ time refers to the scheduled replacement time$)$ up to any proposed scheduled replacement time, if any is warranted. Be sure to relate your recommendation to concrete outcomes such as net monetary benefit, total uptime, or other quantifiable metrics of interest to such a company.

Conduct a Monte Carlo analysis to evaluate the availability of the redundant catalytic reactors. Present quantitative evidence from your simulation as to whether or not a third catalytic reactor would be justified based on certain assumptions about system benefits or the risks of failure.

The time to failure and time to repair information for the catalytic reactor is provided as follows:

Component Name Time to Failure Time to Repair

Catalytic Reactor

$=48\mathrm{.}7$ fpmh

$=1\mathrm{.}3$

$=12$ hours

Develop an ethical stakeholder analysis focused on any system failure modes identified to have safety and$/$or environmental consequences. At a minimum, evaluate the ethical perspectives of at least $3$ stakeholders: neighbors, workers, and owners. Using quantitative information from your FMEA and other analyses together with relevant ethical approaches, describe critical communications, compensation, and$/$or mitigating actions to resolve potential ethical dilemmas.
