Tasks of Project
1. Choosing of the most appropriate methods for analysis at machinery enterprises
2. Elaboration of the effective decision making methodology for production process reliability growth
3. Connection of the methodology with the standard methods for reliability estimation
4. Practical implementation of the proposed methodology5. Transfer of data from analyzing system to decision making
system
Objective is increasing of efficiency and productivity of the company.
Using the new methods and elaboration new tools for enterprise efficiency increasing.
Project for Densel Baltic•The main aim of the current project is Database elaboration for ISO 9001 documentation for SME•The database allows quickly determine relationship between different ISO documents and get constant feedback of the company’s quality system.
Processes reliability assesment
Reliability assessment tool must help engineers quickly and with
great precision estimate the most unreliable places of a production
process and to suggest the most efficient ways for reliability
improvement
Process Model is Base for Reliability Analysis
SMEs encounter with difficulties to implement reliability principles in production due to:• complexity of existing methods for reliability estimation• necessity of expensive software and skilled employees• difficulties in decision making for reliability improvement
Common framework of research
Quantitative measures of system reliability
Recommendation for reliability improvement
