Cowork with Georgia Tech

Oli tehtud mitmed artiklid koos.2 doktoranti külastasid Yan Wang-i, kuid siis kui ta oli UCF ülikoolis.Yan Wang on välis liige meie grandil ETF9460Shevtshemko tegi Yan Wangiga koos projekti Fulbright raames VF446.Rohkem infot koostöö osas saab vaadata www.idssteam.com

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
