What Is China’s Deleveraging Strategy?
China has been the fastest growing economy in the world for the past few decades. The Chinese economy continued to grow even during the recession period. Many economists believe that a growing Chinese economy was a gift to other countries during the slowdown. Since the Chinese economy was growing, international trade was flourishing, and other […]
Conducting the Knowledge Transfer
The Six Sigma project is not complete until the concerned personnel who have to operate the process have the know-how to do so. Many Six Sigma projects have failed because the project team was overjoyed at achieving success. However, one must not forget that improvements are only on paper until they are implemented. And there […]
Role of a Finance Certifier in Six Sigma Project
The Finance Certifier is the only member of the Six Sigma Project team apart from the Project Lead that is selected by the Project Champion. This is because, it is the Project Champions responsibility to ensure that the financials of the Project are absolutely unbiased. Of late, finance certifiers have come under a lot of […]
Disaster Recovery and Business Continuity – Planning Phase
Disaster Recovery and Business Continuity plans if well planned and implemented can help mitigate risks and loss to the business. With increasing competition and complexity of systems and reliance on IT technology, Organizations are focusing in this area to ensure they do not lose out on the business operations in the event of any disaster […]
Warehouse Operational Efficiency and Inventory Health
Any warehouse operations are measured by service levels, volume of transactions handled quality of transactions and most importantly inventory health maintained. By Inventory health in a warehouse, we are referring to Physical Inventory Accuracy, the way inventory is physically kept in locations and discipline maintained in transactions, inventory maintained in the system. Inventory Health, in […]
Product quality determines the success with the product. One of the key drivers of quality is the performance of the product over a period of time. Performance of product is determined by the reliability and redundancy. Reliability increases the efficiency while redundancy increases the current capability and expectations.
Any production organization sets a goal of achieving production efficiency and ability to operate at an optimum level at all the time. Furthermore, the production should be achieved with a least level of wastage.
Production reliability is dependent upon speed, quality and time availability. Equipment failure leads to outage and frequent breakdown, which affect the quality of the products. Frequent machine breakdowns also decrease production speed thus affecting time availability. Theoretically, it is recommended to set employees with a goal of reliability.
Important characteristics of reliability are as follows:
Reliability is divided into two main parts, and they are as follows:
It has been observed that reliability increases if regular maintenance is undertaken.
Redundancy is defined as an addition of information, resource and time to the existing product or system than required for its optimum performance. Redundancy is of following types:
From the above it can be concluded that redundancy provides extra reliability to product and systems. It helps prevention of decline in performance without direct manual intervention. The importance of the redundancy increase even more when system or product is performing a critical, sensitive and complicated task.
Redundancy is sometimes accompanied with failure. These failures are function failure and reliability failure. Functional failure is observed from the start of product life, and it is caused by production or raw material defect. Reliability failure is observed after usage over period of time.
Reliability is measured through reliability index and failure rate. Reliability index is defined as the ratio of production losses to the loss per production loss. Failure rate is defined as the number of failure per unit time, which decreases initially with passage of time.
Total quality management philosophy talks about producing consistent quality of product over a period of time. Redundancy production increases overall cost of production as the extra effort is put into maintaining targeted quality.
