Problems solved by technology

This is often difficult due to the complexity of the data and the concurrency of the information
Additionally, there are disadvantages often associated with collecting and interpreting large amounts of data, which are exacerbated when more data than necessary is collected
Implementing data-intensive solutions is inherently time-consuming and expensive

Embodiment Construction

[0032] The following description and the embodiments illustrated therein are provided by way of illustration of one or more specific embodiments, illustrating the principles of the invention. These examples are provided for purposes of explanation, and similar components are designated with the same reference numerals throughout the specification and drawings.

[0033] The present invention relates to systems and methods for determining and quantifying constraints in automated production or processing equipment. The equipment has multiple automation stations. In one embodiment, the system takes event and status signals automatically collected from each station and processes these signals to derive a measure of throughput for each station. The automatic acquisition of signals is further enhanced by providing an input device which allows a user to manually enter information relating to the performance of the workstation. Rather than collecting a large number of signals, the sy...

Abstract

The present invention is directed to a method and system for identifying, quantifying and presenting to a user constraints in an automated manufacturing or processing facility. A data processing system continuously receives basic status signals and state signals from automation equipment in the facility and evaluates and processes these signals to derive a throughput capability measure (a measure of constraint) of each given manufacturing workstation in the process. The throughput capability measure is expressed as a ratio of an ideal cycle time to an accumulated overcycled time. The accumulated overcycled time includes only delays and excludes any speed-up of a workstation. A constraint is identified as the workstation that has the lowest throughput capability measure as compared with all other workstations in a production line. Preferably, throughput capability measures for all workstations are presented to users graphically. Further drill-down can be provided for obtaining more detailed information about the constraint and capacity loss as well as entering information relevant to the constraint, such as a stoppage or slow-down.

Description

technical field [0001] The present invention relates generally to the field of monitoring the performance of production equipment. Specifically, the present invention relates to a system and method for monitoring and managing the performance of automated production equipment. Background technique [0002] In automated production plants, the optimal operation of the plant depends on the individual production units or locations (production cells or stations) processing the components or workpieces at the respective desired production speed. Stations that are not operating at the desired production rate often constrain product flow and affect the overall throughput of the entire production process. It is generally believed that the production capacity of equipment is limited by its constraints, that is, the workstations that cause relatively the greatest disturbance to the production or workflow of the equipment. Failure to identify constraints in automated production equipme...
