Decision Making

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Distributed Loads: Problem Solving

Distributed Loads: Problem Solving

Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

Block Diagram Reduction

Block Diagram Reduction

The process of deriving the transfer function of a control system often involves reducing its block diagram to a single block. This simplification can be achieved through a series of strategic operations, including relocating branch points and comparators. These operations preserve the overall function of the system while allowing for easier manipulation and combination of blocks.
The first step in this process is the identification and relocation of a branch point. A branch point, where a...

Groupthink

Groupthink

When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated, individuals become less...

Distribution Reliability and Automation

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Summary

Breakdowns in coordinated decision-making in safety-critical systems stem from operational, informational, or evaluative disconnects. Evaluative disconnects are the most challenging to resolve, impacting system safety.

Area of Science:

Human Factors
Systems Engineering
Cognitive Science

Background:

Coordinated decision-making is crucial in distributed safety-critical systems.
Geographically dispersed teams with shared procedures may still have subtle differences in mental models.

Purpose of the Study:

To explore the nature and resolution of breakdowns in coordinated decision-making.
To identify the types of disconnects that cause these breakdowns.

Main Methods:

Analysis of Aviation Safety Reporting System (ASRS) reports involving pilots and air traffic controllers.
Examination of transcripts from the Apollo 13 mission to validate findings.

Main Results:

Breakdowns are categorized into operational, informational, and evaluative disconnects.
Evaluative disconnects were significantly more difficult to resolve than operational or informational ones.

Conclusions:

A taxonomy of disconnects aids accident/incident investigation in distributed systems.
Increasing pilot responsibilities and information may inadvertently increase evaluative disconnects, posing a risk.
