Q2. What are the future works mentioned in the paper "A resilience indicator for eco-industrial parks" ?
This limitation can be overcome in the future by calculating the resilience indicator through a weighted sum of NCI and f. In the future, the resilience indicator can be modified in order to capture a more realistic behavior of an EIP, where some firms are most likely to suffer a disruptive event or they have contingency plans in this situations. Since an EIP can be configured to share material or / and energy, the extension of this indicator to heat transfer networks is proposed for further work. The specific weighs must be properly defined taking into account the aforementioned dependence, since one of them may be overestimated.
Q3. What is the purpose of the present work?
The present work aims at creating a resilience measure for EIPs, considering the decision of the participant to absorb possible disruptive events on them.
Q4. Why are oriented connections considered to quantify f?
Oriented connections were considered to quantify f because the flows under study imply mass or energy transfer from one participant to another.
Q5. What is the minimum flow needed to feed the participant i when k interrupts its activity?
Since after the disruption the participant iis working at its minimum capacity and has lost one input, the minimum flow necessary to feed is Qmin;in i $ Pm2INi;mskFm;i.
Q6. Why are the potential industrial participants hard to convince?
the potential industrial participants are often hard to convince due to security issues when connecting processes, because failures are also propagated through a network (Zeng et al., 2013).
Q7. What is the feasibility of a substitution of flows?
The feasibility of this substitution of flows depends on the capacity of each firm receiving the increased flow and its committed capacity.
Q8. How can an exchange network be designed?
Each exchange network can be designed through mathematical optimization tools, deciding connections and allocations of each participant (Boix et al., 2011).
Q9. What is the equation for the minimum number of connections for nnodes?
The equation for the minimum number of connection Cminn for nnodes is expressed as follows:Cminn ¼ n$ Pn=2R (1)where x is the operation floor, which is the largest integer less than or equal x.
Q10. What is the general goal of these metrics?
The general goal of these metrics is to measure the impact of a partial and complete disruption over the park and their participants, focusing on the most affected nodes and on the loss of efficiency of the park.
Q11. What is the applicability of the resilience indicator on networks with a unique layer?
To study the applicability of the resilience indicator on networks with a unique layer, consider the Kalundborg and Ulsan networks.
Q12. What is the definition of the output available capacity for a participant l?
With this focus, the outlet available capacity for the participant l is defined as:Qoutm ¼0@Qmax;outm $ Xw2OUTm;wskFm;w1A withm2INinfkg (8)It is important to note that Qoutm is minimumwhenm is workingat its maximum capacity ( Pw2OUTm;wskFm;w ¼ Q max;out m ).
Q13. What is the minimum flow required to compensate the activity interruption of a participant?
The total lack of flows related to a disruption in k is defined as:L k ¼ Xj2INkL in j$k þXi2OUTkL out i$k ck2N (11)Using this term, the total required flow to compensate the activity interruption of a network participant is obtained.
Q14. How can a network be considered in f?
Since in the reality the quality of the flows is important in order to comply with the requirements of the participants, this aspect can be considered in f through the use of different layers.
