Management of production flows, quality and lead times - 2020

Initiation to practice-based production flow simulation


This course will allow technicians and engineers involved in the design or improvement of the production process of goods or services to learn and put into practice a simulation tool.

The possibilities offered by such a tool should enable companies to develop their ability to manage and control their operational processes, particularly when it comes to heavy investment decisions.


The course lasts 2 days (14 hours of computer-based practical work).


This course is primarily practice-based. It uses simple but specific and realistic processes as a guideline so that participants can get a clear idea of the potential of a simulation tool.

The tool used will be Witness (, one of the most prevalent in industries and services for nearly 30 years. However, the functionalities and the general approach of carrying out a simulation study will be transferable to any other tool. 

The strength of Witness lies in its 'business' modeling logic, quite natural for a flow expert, and in its interactive and visual interface that does not require programming in a computer language. The modeling relies on a set of discrete generic elements (article, machine, stock, resource, etc.) and continuous elements (fluid, processor, reservoir, pipe, etc.) to be instantiated to obtain the process model. The flow logic is then described by laws and actions that can include, if necessary, elementary algorithmic structures (IF ... THEN ... ELSE ...) associated with logical elements (variables, attributes, functions, etc.). Witness remains a very powerful and interoperable tool: read/write CSV files, XLS, connect to databases, import CAD drawings, export statistics and indicators to Excel, etc.


Course level: Basic

Proficiency in the basic functions of Excel + basic algorithmic structures.

Recommended but not essential: process modeling skills (BPM), a continuous-improvement approach, and Lean.
