Ordinal Level of Measurement00:55

Ordinal Level of Measurement

33.5K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...

Emerging Adulthood01:27

Emerging Adulthood

656
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Introduction Cardiac Emergencies

321
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

What is Natural Selection?

128.1K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Applications of GIS: Disaster Management and Emergency Response

500
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Área de la Ciencia:

  • Investigación de Operaciones
  • Ciencia de la Decisión
  • Gestión de la Cadena de Suministro

Sus antecedentes:

  • La selección improvisada de proveedores de emergencia (IESS) es un problema complejo de toma de decisiones multiatributo (MADM) debido a la incertidumbre y la urgencia inherentes.
  • Los métodos IESS existentes luchan con pesos de expertos subjetivos, opiniones inciertas y altos costos computacionales, lo que limita su aplicación en el mundo real.

Objetivo del estudio:

  • Introducir un nuevo Enfoque Robusto de Prioridad Ordinal de Consenso (OPA-RC) para la IESS.
  • Superar las limitaciones de los métodos existentes proporcionando una derivación objetiva de pesos y optimización robusta.

Principales métodos:

  • OPA-RC deriva objetivamente las puntuaciones de importancia de los expertos utilizando la concordancia de clasificación por pares.
  • Un marco de optimización robusta incorpora estas puntuaciones a través de un conjunto de ambigüedad basado en el presupuesto para manejar la ambigüedad de las puntuaciones.
  • El modelo se reformula como un programa lineal computacionalmente eficiente con una solución de forma cerrada.

Principales resultados:

  • OPA-RC demuestra su efectividad a través de experimentos basados en escenarios, incluyendo análisis de resultados, sensibilidad y comparaciones.
  • El enfoque deriva objetivamente la importancia de los expertos, mitigando la subjetividad.
  • El método proporciona una herramienta de apoyo a la decisión robusta y computacionalmente eficiente.

Conclusiones:

  • OPA-RC ofrece una solución transparente, robusta y computacionalmente eficiente para IESS.
  • El enfoque permite una selección confiable y resiliente de proveedores en escenarios críticos de desastre.
  • Este método mejora la toma de decisiones en condiciones de incertidumbre en la logística de emergencia.
