ANS:D - travel chart

A travel chart, also known as a travel distance chart or travel path chart, is a graphical representation used in industrial engineering and manufacturing to analyze and optimize material flow or movement within a facility. It provides a visual depiction of the distances traveled by materials, components, or workers as they move between various workstations or locations in a production process. Here's how a travel chart is typically created and utilized:

1. Data Collection: The first step in creating a travel chart involves collecting relevant data about the layout of the facility, the locations of workstations, and the paths traveled by materials or workers.
2. Mapping Paths: Using the collected data, the paths traveled by materials or workers are mapped out on a diagram or floor plan of the facility. This can be done by drawing lines or arrows to represent the routes taken.
3. Distance Measurement: The distances traveled along each path are measured and recorded. This may involve using a scale or measuring tool to determine the lengths of the paths.
4. Analysis: Once the travel chart is created and distances are measured, it can be analyzed to identify inefficiencies or areas for improvement in the material flow or workflow. For example, excessive travel distances or congested pathways may indicate opportunities for layout optimization or process redesign.
5. Optimization: Based on the analysis, changes may be implemented to optimize material flow and reduce travel distances. This could involve reorganizing workstations, rearranging storage areas, or implementing new handling procedures to streamline operations and minimize wasted movement.
