The Premium Service SIMATIC SIPAT Consulting is split into three complementary modules that can be ordered individually:
Module 1:
Determination of PAT potential through analysis by experts
- One-day workshop for analyzing the customer's production processes
- Participants: Siemens experts and representatives of the client with profound knowledge of the process
- Pre-definition of workshop details between client and contractor, e.g. discussion of the client's production processes and possible real-time process analysis systems, if necessary including tour of the existing production plant
- Assessment of the benefit of the PAT implementation on the basis of criteria such as:
- Avoidable incorrect batches
- Reducible release tests
- Effect on process cycle times
- Necessary investment
- Result: Workshop documentation with qualitative evaluation of the PAT potential, and specific recommendations for further actions
Module 2:
Preparation of a feasibility study
- Feasibility study to verify and narrow down the potential identified in Module 1 (processing time up to two weeks):
- Detailed consideration of as many as 10 recorded processing steps
- Closer examination of potential process analysis systems with regard to suitability and integration into the process
- Participants: Siemens experts and representatives of the client
- Basic material:
- Customer information
- Values gained from own experience
- Literature about process analysis systems
- Manufacturers' information process analysis systems
- Results of an expert analysis (Module 1)
- Inclusive services:
- Evaluation of existing production processes, process parameters and process controls: Apparatus, process knowledge, process control, manageability and performance capability of the processes, specifications of the raw materials
- Evaluation of product quality Identification of the known quality parameters, their limits and analytical test methods
- Correlation of quality and process parameters, evaluation of known or suspected causes of process failures (batches outside the specification)
- Determination of processes with potential for improvement through in-process control
- Characterization of the tasks for in-process control
- Evaluation of known/potential online or inline analysis methods and analyzers for the in-process controls; assessment on the basis of data from corresponding offline and online laboratory methods
- Evaluation of potential process interfaces or potential equipment for automatic sampling
- Extra services (separate charge):
- Siemens examines a selection of in-house process analysis systems for suitability for the real-time process analysis
- Execution in own laboratories with samples of varying quality
- Invoicing of analysis performed by Siemens on pro rata basis
- Result: Documentation of the feasibility study with concluding evaluation of the PAT potential and specific recommendations for further actions
Module 3:
Implementation of the prepared feasibility study
- Implementation of knowledge gained in Modules 1 and 2 in a specific project for supporting the PAT implementation
- Content is the subject of an individual agreement between client and contractor
- Typical service content:
- Risk analysis
- Support in selecting and installing a process analysis system
- Support in drawing up the "Design of Experiment" (DoE) and execution of the experiments for structured investigation of the "Design Space"
- Data analysis, e.g. multivariate (MVDA)
- Interpretation of the results
- Process optimization on the basis of the understanding gained of the process and, if necessary, modification of the "design space"
- Basis for the individual agreement is a project-specific quotation provided by Siemens as the contractor
- Inquiries for production of a quotation should be directed to the address specified under "Further information"
Note:
The modules of the Premium Service SIMATIC SIPAT do not include any traveling expenses. Traveling expenses from the Hoechst Industrial Estate, Frankfurt am Main, Germany, will be invoiced separately.
