GPC AUDIT OF A SYSTEM

The GPC tools offer a proper study of the operation of a complex system (industrial equipment, production line, engine, biological process…) through a history of measures.

These tools identify the major factors that influence the system’s behavior and its sources of disturbance.

Having identified these factors and measured their effects on each variable of the system, it is possible to change the system behavior, in order to:

  • Improve quality output.
  • Improve productivity.
  • Reduce costs.

STEPS OF A GPC AUDIT

Step 1: Identification of a studied system

Step 2: Identification of available data

Step 3: Identification of the issue

Identification of the issue and review of the compatibility of available data with the objectives of the study.

Step 4: Standard GPC analysis

First standard GPC analysis of the available history, with an edition of a standard report (about 20 pages).

Step 5: Review of the results of the standard analysis

  • Review of the results of the identification of responses to the issue by specialists of the studied system.
  • Identification of outstanding questions.
  • Design of a new customized analysis to provide responses to the open questions.

Step 6: Customized GPC analysis

Step 7: Review of the results of the customized analysis

  • Identification of the answers obtained from the specialists of the studied system.
  • Identification of outstanding questions.
  • Potential design of a new customized analysis to provide solutions to the open questions.

Step 8: Iteration on the steps 6 and 7

Iteration on the steps 6 and 7 if a new analysis was defined.

An Audit will lead to:

  • The improvement of the system operation through targeted actions.
  • The establishment of a periodic monitoring according to a monitoring model defined by the Audit, in order to prevent excesses and to make improvements.
  • The establishment of a real-time monitoring to ensure the continuous operation of the system.

ACTORS OF A GPC AUDIT

A real GPC Audit, leading to actionable modifications of the studied system must be run by a qualified user of the GPC technology in collaboration with experts.

This qualified user, internal to the company (GPC System consultant or certified consultant) will use the modules included in the GPC Expert subscription (particularly GPC Scan).

GPC System offers qualification training for GPC Audit.

An audit may include data validations, selections of variables and observations, creation of new variables obtained by complex transformations on the data, the integration of targets and specification limits, sensitivities settings, intelligence of anomalies… It can produce a usable model of analyses for periodic monitoring (daily, weekly…) or for real-time monitoring.

However, faster superficial analyses are possible and useful:   

FLASH AUDIT

GPC System offers “Flash Audit” to assess whether the GPC tools are adapted to a history of data and an identified issue: it will carry out the first steps 1 to 7 of a GPC Audit within a week, generally requiring a day of GPC consultant.

GPC GO

The GPC Go Module can easily start a standard analysis of the history of measures and get a standard 20 pages report that mentions the most important results of the analysis. This module is used by an expert in this field after an initial training on the interpretation of the main results of GPC analysis: GPC First training. This user performs steps 1 to 5 of the GPC Audit independently. The GPC View module is associated to the GPC Go module, in connection with the GPC First subscription to provide access to all possible GPC results and to complete manually, if necessary, the standard published report.
