The article presents the application of selected quality engineering methods for solving a problem with product quality in the production process of plastic bags. Defects present in the product were identified and hierarchized by the number of defects in the total production volume. Next, using the Ishikawa diagram, the main causes for the occurrence of the most significant defect, i.e. "foil sticking together" were identified. The scale of the problem for the various causes was determined using FMEA, corrective and preventive measures were proposed and their effectiveness estimated. Thanks to the analysis it was possible to take actions which lead to a decrease in the number of faulty products and introducing preventive measures to reduce the risk of problems occurring in the future.
An enterprise which is managed in a modern way should be based on the concept of knowledge management. It is particularly important in the case of processes related to facility maintenance, where the efficiency and effectiveness of work is directly connected with the employees' knowledge. Improvement of processes involved in facility maintenance has a real influence on the productivity of a manufacturing enterprise. High accessibility of technical equipment and its correct functioning influence not only production efficiency but also the quality of products and the safety of operators. The article is a description of an attempt to implement one of quality engineering methods for improving the facility maintenance process. The author decided to use the 8D method to shorten the duration of downtimes caused by breakdowns. Owing to the conducted analysis and the implementation of the improvement and preventive actions, we were able to shorten the duration of a downtime of a machine having a crucial importance for the company. Investigations and implementation were conducted in one of Silesian production plants.. Keywords maintenance quality improvement process 8D
Abstract. The paper presents the example of practical application of theory of constraints. We use this conception to improve production process in the case of company producing electrical equipment for the mining industry. During the observation and on the basis of the ERP system used in the company as well as process mapping, the area in which the so called "bottleneck" problems are present was determined according to the theory of constraints. Analysis of the "bottleneck" using theory of constraints was carried out in the Paint Shop department, as this is the department where the biggest financial losses are generated and the entire painting process inefficient. The aim of the paper is to analyze of the "bottleneck" using theory of constraints in the production industry to improve the process.
Abstract:Increase in the number of orders, the increasing quality requirements and the speed of order preparation require implementation of new solutions and improvement of logistics processes. Any disruption that occurs during execution of an order often leads to customer dissatisfaction, as well as loss of his/her confidence. The article presents a case study of the use of quality engineering methods and tools to improve the e-commerce logistic process. This made it possible to identify and prioritize key issues, identify their causes, and formulate improvement and prevention measures.
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.
