ReviewModeling of tacit knowledge in industry: Simulations on the variables of industrial processes
Introduction
According to Bertalanffy (1973), physiological limitations and paradigms, which determine human capacity, limit the perception of reality in overall phenomena. From this observation, one is faced with the need for employing computing tools so that they can assist in understanding those phenomena. In this study, the phenomenon is applied in such (a) way(s) that the root cause(s) of the defect(s) may be diagnosed during the assemblage of Metal Aerosol Packaging in a Metallurgical Company, its application being intended for industrial processes in general.
The state of the art about how is made knowledge acquisition Wright (1987), Hoffman, 1987, Liou, 1990, Cooke, 1994, Hoffman et al., 1995, Cairo, 1998, Tang et al., 2008, Kim, 2014, Schreiber et al., 2000, Alwis and Hartmann, 2008, Pitchforth and Kerrie, 2013, Oguz and Sengun, 2011, Lemos and Luiz, 2012, Lemos (2012), Kim et al., 2011, Kim, 2014 pursued during the preparation of this study, has shown that there is not a methodology to mapping and elicitation for the of tacit knowledge acquisition in industry, but rather the use of knowledge elicitation techniques used in isolation, without a logical sequence and objective oriented to analysis and problem solving. The methodology has been created based on a systemic approach, which is used in the observation process of complex phenomena in the industry. Concepts of Artificial Intelligence (AI) specifically expert systems (ES), have been used in the research to support the value of tacit knowledge in problem solving inside industries, as a way of disseminating it in internal processes, as well as promoting the organizational learning.
Rezende (2003) says that the main goal of AI is to enable the computer to perform human functions; so, the incorporation of knowledge proves to be essential for the success of any Intelligent System. This statement contemplates the proposed study, which consists in mapping the type of collective tacit knowledge relevant to the solution of the phenomenon observed, thus generating a knowledge management system.
According to Alwis and Hartmann, 2008, Lemos and Luiz, 2012 the transference process of knowledge from tacit to explicit within innovation management in organizations is a competitive advantage once explicit knowledge is already used in the organization; thus, it can be copied by competitors. On the other hand, tacit knowledge is new and, as such, the company will be able to remain for some time with a competitive advantage on its side.
As scientific methodology to structure the sequence of activities used for eliciting tacit knowledge, a technique called systemography has been used. It allows its users to approach, understand and interpret the phenomenon in a systematic way. During the application of the sequence of activities, some quality tools were implemented such as Brainstorming, Pareto Charts and the Ishikawa Diagram. These are tools often used to solve problems in industrial processes.
The objective of this research is to build the methodology, which aims to transform collective tacit knowledge into explicit by using knowledge elicitation techniques, associated to quality tools structured by systemography, represent it in a symbolic language and production rules, and model it in two expert systems which can assist the investigation of defect causes during the metal packaging production process. The production rules, which have been created, were stored in the knowledge’s foundation in two different types of expert systems: probabilistic and non-probabilistic, to be utilized by different users. The first one mentioned will be used at the operational level and the second one at the tactical level of the organization. The expert system tools used were EXPERT SINTA and NETICA. The methodology is named MACTAK – Methodology for Acquisition of Tacit Knowledge.

Theoretical foundation
This section presents issues related to the study’s development, such as: systemography (systemic approach to observation of complex phenomena), quality tools, elicitation knowledge techniques, tacit knowledge, Artificial Intelligence and expert system.
Methodology
The method used in the study was classified as exploratory as its main goal. An exploratory research on the theory forward to the scientific community in the areas of Artificial Intelligence and knowledge management, in order to better adapt the methodology for mapping and elicitation of collective tacit knowledge to the reality is intended to meet Gil (1991) was performed. The methodology, second Santos (2000), can also be classified as action research, because the researcher is one of the
Results and discussion
This section demonstrates the application of the proposed methodology for elicitation of collective tacit knowledge, since the mapping of the type of knowledge to be elicited by the development of production rules, form chosen for formal and explicit representation of tacit knowledge.
Conclusions
The research regarding knowledge acquisition revealed that the practices of knowledge elicitation systematically presented in this work are still little explored in the industries and organizations in general, especially on the optical mapping of the type of knowledge to be elicited. The tacit knowledge is a kind of hard to be voiced to others knowledge, which makes it rarely quoted in an active scientific community in industry in manufacturing operations. Thus, the scientific contributions of

Using Bayesian belief networks to improve distributed situation awareness in shift changeovers: A case study
2022, Expert Systems with ApplicationsA framework to acquire explicit knowledge stored on different versions of software
2016, Information and Software TechnologyCitation Excerpt :As a result studies that could be applied to re-acquire explicit knowledge as well as some methodologies where found, however, most of them focus on tacit knowledge; the distinction between these two types of knowledge has been widely studied [12,4], a possible reason for it is the perception that tacit knowledge is more difficult to share and not readily codified [16] sometimes the production of new knowledge has more weight than the exploit of the one that is already captured [32,33]. The conversion to explicit knowledge to be used on KM tools [34], initiatives to manage knowledge through including database integration and conversion, internet architectures, artificial intelligence or technical support for decision making [35] corporate memory generation focused on efficient representation of tacit knowledge [23], development of frameworks to facilitate transfer [33] or how to get interaction between groups [36] are some study cases on acquisition and re-use of knowledge. After the review, the lack of studies on re-acquisition of explicit knowledge is evident, most of the studies and frameworks assume that if knowledge is already encoded and captured it can be exploited.
Thread-based probabilistic models for expert finding in enterprise Microblogs
2016, Expert Systems with ApplicationsCitation Excerpt :An ‘expert’ is typically defined as a person with relevant ‘expertise or experience’ for a given query; and an ‘expert-finding system’ is a type of intelligent search engine that retrieves ‘a list of ranked expert candidates who match the expertise query’ (Becerra-Fernandez, 2006; Ehrlich & Sadat Shami, 2008). In the research reported here we thus contribute to the following aspects of expert and intelligent systems (Liao, 2005; Sahin, Tolun, & Hassanpour, 2012; do Rosário, Kipper, Frozza, & Mariani 2015; Vásquez-Bravo, Sánchez-Segura, Medina-Domínguez, & Amescua 2014): Establish that business conversation shifting to Enterprise Social Media provide a unique source of tacit knowledge that merits further research into useful knowledge acquisition methods.
