Abstract. In this paper linear programming was shortly characterized. The implementation of some basic functions for Octave have been presented. It is the GNU General Public License program for the optimization the cost-benefit criterion in production processes. A problem of dividing production tasks between workstations was presented in way that the cost of the realization was the smallest. The final score of the course was obtained the computational environment Octave using the GLPK (GNU Linear Programming Kit) function.
The article presents a case study on the use of specially prepared 5W-1H and 4M sheets for the analysis of the problem during the visual inspection process of the electric device, in order to solve it. The identified problem was related to inconsistent assessments during the visual (alternative) inspection of chamber gaps of the electric switch. The research methodology was presented the same as results confirming the effectiveness of the problem analysis in the area of quality control by using these two methods of Lean and WCM concepts. The article aimed to show that a skilful and pragmatic approach to the problem supported by appropriate tools can contribute to its effective solution.
In the chapter was presented enterprise producing air bags. described. Toyota’s management principles by Jeffrey Liker were pointed out, which refers to production process (second). An innovative BOST questionnaire survey was characterized as a tool for transformation of Toyota’s management principles into questions. Survey and research method determined as BOST (the name of the is an acronym created from the first two letters of the name and surname of his creator i.e. Stanislaw Borkowski, professor of technical and economic sciences, the acronym is legally protected). Results of the questionary were introduced. It was made an analysis in the range of the principle 2 of Toyota. It was shown analysis of respondent’s characteristics. Next structure of assessments was determined and some statistical graphs were built.
Abstract:The article presents research results in a scope of evaluation importance in visual control usage in the production processes of enterprises from automotive industry. The significance of visual control in a production process was characterized. An innovative BOST questionnaire survey was described as a tool for transformation of Toyota's management principles into questions. The survey questions from BOST study were described, which is used in evaluation of the visual control importance with reference to the second Toyota's management principle (question E3). The analysis of respondents preference in ranging factors of the second Toyota's management principle was conducted using comparative evaluation of Thurstone's method, as well as the degree of similarity between these factors was indicated. A subjective factor was assessed by employees of automotive industry as one of less significant in the production process.
In the paper the problem of personnel allocation under threat was presented. The possibilities of undertaking optimization measures in the process of workers’ health and safety and expenses incurred were emphasized. A mathematical model for this issue has been formulated. An algorithm solving the problem of staff allocation was presented. The evaluation criterion for this assignment was the minimization of worker safety risks. Simultaneous optimization of expenses incurred in the implementation of production tasks was taken into account. The productivity of the staff and all existing jobs with the skills of the employees also was considered. This problem was solved using GNU Octave. The example presented in the paper shows that in case of the most unfavorable allocation of tasks to employees, it will lead to a significant reduction in profits and may increase the risk of undesirable situations. The proposed analysis is the starting point for determining the risk in case of multi-position work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
