Methods and techniques for acquiring manufacturing knowledge
Published in Justyna Patalas-Maliszewska, Managing Manufacturing Knowledge in Europe in the Era of Industry 4.0, 2023
In the context of performing repetitive activities, tacit knowledge can be acquired by visualising the work performed by workers in the form of a model. Business process modelling (BPM) is a graphical representation of processes and is necessary to define the purpose of a given process and its resources, and adopt a specific notation, i.e. a specific set of symbols and rules for their use serving to visualise the course of the process. There are three groups of process modelling: formal (in mathematical language), informal (linguistic-verbal) and semi-formal (linguistic and graphic methods). The following process description languages can be distinguished: EPC (Event Process Chain), BPMN (Business Process Modelling Notation), BPEL (Business Process Execution Language) and BPEL (Business Process Execution Language for Web Services).
Molding Processes
Published in Richard L. Shell, Ernest L. Hall, Handbook of Industrial Automation, 2000
The analysis of resin flow in the mold is very important from the view point of the mold design. In addition, process modeling is particularly useful in understanding, designing, and optimizing process conditions. An overview of the RTM process, its manufacturing problem, and modeling aspects is given in Refs. [197–199]. A number of two-dimensional flow simulation attempts are based on the shell model under the assumption that there is no flow in the thickness direction. Some three-dimensional attempts have also been made [200,201]. The analysis of flow is typically based upon finite-difference [202–205], boundary-element [206–209], control-volume [210–221] and finite-element methods [222–231]. In addition, numerical schemes using the body-fitted finite-element method [232–237] and combination of flow analysis network for movement of the free surface and finite-element method to solve governing equations for each successive flow front location [238] are used.
Embedding BPM In The Organization
Published in John Jeston, Business Process Management, 2018
Process modeling tools: Typically, various process modeling tools are used, but predominantly Visio and PowerPoint. This results in a range of inconsistent process assets that provide little or no ability to achieve cross-collaboration within the organization.
Review of simulation software for cyber-physical production systems with intelligent distributed production control

(10a & b) Animation and integrated process flow animation: animation is an important feature validation of the created model(s). In Anylogic animation is well integrated into the tool. For example, building a model with the Process Modelling Library automatically creates a simple process flow visualisation which helps in validating the model. An example of this is shown for the Batcher in Figure 10, in which the integrated visualisation shows how many products have entered/exited/are currently being processed at each production step of the Batcher. Anylogic also allows every object to be clicked during simulation for further inspection, and allows parameters and variables to be changed during simulation. More advanced 2D and 3D animation options are also well supported, but these were not used in the case study.

Process modeling is generally utilized to increase the overall efficiency of the process, product purity and to determine the optimum process parameters from experimental data (Kwan, Hu and Lin 2018). In this regard, SuperPro Designer has been used for process development, economic analysis and waste minimization during the production of various commercial chemicals (e.g., ethanol from sugar cane residues (Michailos, Parker and Webb 2016), microalgal biodiesel production (Heo, Heo and Lee 2019), biogas from anaerobic digestion of complex organic matter (Mani, Sundaram and Das 2016)). The proposed process to produce boric acid via SuperPro Designer consists of a CSTR, a filtration-washing unit to separate gypsum, a crystallization unit, a filtration-washing unit to separate boric acid, a decantation unit, and a drying unit.
Development and validation of a batch fluidized bed dryer model for pharmaceutical particles

The pharmaceutical production, and other sectors like food and mining, frequently relies on batch fluidized bed dryer (FBD) for their water removal needs in particulate materials. While they are efficient dryers, their operation in industry are typically fixed procedures, which is presumably suboptimal. Process modeling is one of the most versatile and promising tools to optimize production efficiency. In opposition to empirical approaches, starting from the first principles can potentially increase the applicability range. However, the growing complexity of modern industrial processes puts a curb on pure first principle developments. Phenomenological modeling is a good compromise in such circumstances.
