Study Notes

Standard Data System (SDS)

A database of normal time values, organized by work elements, used to define time standards for tasks with similar work elements.
Advantages of SDS:
- More efficient to use when numerous tasks are similar
- More productive to use with large data sets to establish standards
- No need for observation of actual tasks to record data and establish standards
- Time standards can be established at a lower cost
- Time standards are more accurate and consistent

When to Use SDS

When similar tasks are involved
In batch productions
With large number of data sets

Work Elements in SDS

The database is organized by work elements
Normal time is provided for each work element
Important to classify work elements into different categories:
- Setup vs. production elements
- Constant vs. variable elements
- Worker-paced vs. machine elements
- Regular vs. irregular elements
- Internal vs. external elements

Setup vs. Production Elements

Setup elements: associated with activities required to change over from one batch to the next
Production elements: associated with the processing of work units within a given batch
Batch time: Tb = Tsu + Q Tc

Constant vs. Variable Elements

Constant elements: same time value in all time studies and tasks
Variable elements: same basic motion elements but normal times vary due to differences in work units

Worker-Paced vs. Machine Elements

Worker-paced elements: time values depend on the worker's pace
Machine elements: time values depend on the machine's cycle time

Motion-Time Tables

Tables used to determine time values for different body members and motions
Examples: WF-Motion-Time Table (Arm), WF-Motion-Time Table (Leg), etc.

Simplified Work Factor System

A higher-level system used for medium quantities
Uses a systematic working factor process
Effective in planning projections before actual development starts

Abbreviated Work Factor System

A higher-level approach used for small workplaces
Based on a comprehensive system of work factors
Ideal for quick measurement process

Ready Work Factor System

A higher-level job factor used for manual labor
Commonly used in manufacturing and other industries
Created to meet the need for a simple measurement method
