Use Case Printing Systems

Today’s printing industry is dominated by large, global printing companies capable of processing orders of any size quickly and efficiently which has led to an increased demand for more reliable printing systems. The Heidelberger Druckmaschinen AG are using SAKE as part of a preventative service to optimise their efficiency.

Central requirements are:

  • The development of an automatically generated algorithm which uses a trigger point (i.e. error time) within the log file data of a printing system to describe causal connections
  • Setting up a knowledge base which automatically processes, structures and anonymises messages for service technicians

 

 

Use Case 1: Printing systems error analysis

Use Case 1 is implemented in two steps:

1.1

All historic information (from day 1 to 6 months) relevant at the time of error and related to the time of the error is established in the log data. The results are compiled in a list of specific message IDs which are very likely (> 95 %) to be linked to the error. The data results are verified by technical service experts at HDM AG. 

The information gathered in 1.1 is used to generate an algorithm (EPN) which automatically simulates the error alongside the real error and compares the two. If possible self-optimization via servo loops is implemented.

1.2

The information gathered in 1.1 is used to generate an algorithm (EPN) which automatically simulates the error alongside the real error and compares the two. If possible self-optimization via servo loops is implemented.

Use Case 2: Printing system analysis as a preventative measure

The correlations gathered from 1.2 are in turn used to generate an algorithm (EPN) in USE CASE 2 which uses the correlations from Use Case 1 to establish the likelihood of future errors occurring (prevention).

Result of Use Case 2:

An algorithm will be generated from Use Case 2 which can be used by the remote monitoring platform to predict highly likely future occurrences of the error (what error, at what time and with what consequences?). The purpose is to establish a time frame to help develop preventative error recovery measures.
