## Location in Objects Pane

## Model Description

### Model Form

${{\Gamma }_{abs}} + {{D}_N}=\left\{ \begin{matrix} {{\Gamma }_{t}}\cdot \left( 1-{{d}_{\text{pwr}}}\cdot \left( 1-P \right) \right)\cdot \left( 1-{{d}_{\text{wtr}}}\cdot \left( 1-W \right) \right) & ; & {{\eta }_{S}}=0 \\ \left\{ \begin{matrix} {{\Gamma }_{t}}\cdot \frac{r}{2} & ; & \text{before restoraion} \\ {{\Gamma }_{t}}\cdot r & ; & \text{before repair} \\ {{\Gamma }_{t}}\cdot \left( 1-{{d}_{\text{pwr}}}\cdot \left( 1-P \right) \right)\cdot \left( 1-{{d}_{\text{wtr}}}\cdot \left( 1-W \right) \right) & ; & \text{after repair} \\ \end{matrix} \right. & ; & {{\eta }_{S}}>0 \\ \end{matrix} \right.$ Important Notes:
• The "potential capacity" response is the same as "absolute capacity" response with the difference that it is ascending during the recovery period.
• The "available capacity" response is the same as "potential capacity" response with the difference that the post-hazard hospitalized injured people are subtracted from the potential capacity.
• If it is desired that the capacity of the healthcare unit will be ascending during the recovery period, the "potential capacity" response must be used.
• To consider the events of injuries treatment during the post-hazard period in Discrete Event Analyzer, the "available capacity" response must be used.

• No

## Properties

### Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

### Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

### Healthcare Information Model

• The associate Healthcare information model

### Normal Demand

• $${D_N}$$ = The hospitalization demand on the healthcare unit in normal condition

### Structural Damage Ratio

• $${\eta _S}$$ = Structural Damage Ratio

### Nonstructural Drift Damage Ratio

• $${\eta_{ND}}$$ = Non-structural drift damage ratio

### Nonstructural Acceleration Damage Ratio

• $${\eta_{NA}}$$ = Non-structural drift damage ratio

### Content Damage Ratio

• $${\eta_C}$$ = Content damage ratio

### Repair Status

• $${\varsigma_{rep}}$$ = Status of Repair operation of healthcare building (1 if completed, 0 otherwise)

### Restoration Status

• $${\varsigma_{rst}}$$ = Status of Restoration (1 if completed, 0 otherwise)

### Recapture Factor

• $${r}$$ = recapture factor accounts for the fact that the business-related losses from earthquakes can be recouped to some extent by working overtime after the event (FEMA NIBS 2012)

### Power Serviceability

• $${P}$$ = The serviceability status of the upstream electricity provider

### Power Dependency

• $${d_{pwr}}$$ = The dependency of the Healthcare unit on power

### Water Serviceability

• $${W}$$ = The serviceability status of the upstream water provider

### Water Dependency

• $${d_{wtr}}$$ = The dependency of the Healthcare unit on Water

## Output

• $${R_{abs}}$$ = The absolute revenue of the Healthcare unit in terms of number of beds
• The output is an automatically generated generic response object, which takes the object name of the model plus “AbsoluteResponse”.
Note: The absolute capacity demonstrates the current capacity of the commercial unit based on its current condition.
• $${R_{pot}}$$ = The potential capacity of the Healthcare unit in terms of number of beds
• The output is an automatically generated generic response object, which takes the object name of the model plus “PotentialResponse”.
Note: The potential capacity features the condition that the capacity is ascending during the recovery period.
• $${R}$$ = The available capacity of the Healthcare unit in terms of number of beds
• The output is an automatically generated generic response object, which takes the object name of the model plus “AvailableResponse”.
Note: The available capacity features the condition that the post-hazard injured people are hospitalized and therefore, the serviceable capacity is reduced.
