    Opis:
    The main focus was to reduce defects in production lines of a newly started crackers manufacturing company as well as develop such a system so that mass defects can’t happen again. To ensure a rated benefit & make the market value constant in the market an efficient system is one of the primary requirements. The prime qualities must be constant. So, to ensure that the causes of defects will not happen again the root-cause analysis has been done from the record of check sheet. Then all the errors from vital elements of production were detected and actual parameters, ingredient composition, temperature, pressure, steam supply etc. have been tried to maintain constantly. The co-operation of top to bottom hierarchy made this process successful & also able to build a permanent preventive system. Finally, a stable & reliable production system has been established to maintain target production and achieve maximum benefit ensuring excellent quality of product.

    Opis:
    Energy conservation is an important step to overcome the energy crisis and prevent environmental pollution. Casting industry is a major consumer of energy among all the industries. The distribution of electrical energy consumed in all the departments of the foundry is presented. Nearly 70% of the energy is consumed especially in the melting department alone. Production of casting involves number of process variables. Even though lot of efforts has been taken to prevent defects, it occurs in the casting due to variables present in the process. This paper focuses the energy saving by improving the casting yield and by reducing the rejections. Furthermore an analysis is made on power consumption for melting in the induction furnace to produce defective castings and improvement in the casting yield. The energy consumed to produce defective castings in all other departments is also presented. This analysis reveals that without any further investment in the foundry, it is possible to save 3248.15 kWh of energy by reducing the rejections as well as by improving the casting yield. The redesign of the feeding system and the reduced major rejection shrinkage in the body casting improved the casting yield from 56% to 72% and also the effective yield from 12.89% to 66.80%.

    Opis:
    The overarching aim was to reduce the frequency of connection failures that occur due to the connection speed and reliability, and identify, characterise and optimise the key process input variables (KPIVs). An experimental research approach with an inbuilt planned manipulation to one or more variables in the experimental data set was adopted. Key elements of the Six-Sigma methodology were applied to resolve the issue of high failures due to connection speed and reliability between two Li-Fi transceivers. KPIVs were successfully identified, characterised and optimised to implement a permanent corrective action to ensure a reduction in connection failures from 17% to 0%. The alignment between two Li-Fi transceivers along with Li-Fi cut-out was found to be critical in achieving good connection speed and reliability. The interference due to ambient visible spectrum lighting found to be statistically insignificant. This study explored the application and benefits of accessible wireless data communication technologies. Moreover, it sheds light on the probable factors that may influence Li-Fi connection speed and areas for future research. The current research provides a Six- Sigma based solution to high connection failure rates while using an infrared-based Li-Fi transceiver. Results also offer insights into the analytical tools that were found to be effective during the problem-solving process.

    Opis:
    Due to the constantly growing competition on the market, enterprises are looking for a way to improve the quality of their products and services. The quality of the product is largely dependent on the number of defects present, so efforts should be made to minimize them. The article presents a method of limiting the formation of defective products, in this case, vehicle components – vibration dampers. The method was developed using selected quality management methods and tools.

    Opis:
    The current research study aimed to explore the utility of selected problem-solving tools and techniques in root-cause analysis to demonstrate their practical application. An experimental research design adopting a positivist empirical approach with a deductive strategy was followed to assess the effectiveness of a combined (8D & Six Sigma) problem-solving approach in reducing a high defects rate of a mixer shower assembly line. A novel application of the 8D framework in combination with Six Sigma and other analytical tools was found highly effective in reducing the reject rate from 11.84% to 0.11%. Successful identification of the root cause led to the implementation of permanent corrective action ensuring a long-term stable assembly process. The research study provided a problem-solving framework that was found effective in resolving a complex problem and implementing long-term corrective action in an assembly production line. However, this framework can be used in other industries. The research study provides a solution to a high number of leak rejects in a subassembly where “O-seals” are used between mating parts. It also provides analytical tools that were found highly effective during the problem-solving process.
