Objectives serve to guide the design process and measure your results. Current Work Location: Bangalore; Preferred Work Location: Anywhere in India or International. Its degree of reliability has to do instead with the predictability of its relationship with whatever is being tested. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. Reliability planning – 9 questions (Benchmarking, reliability planning, etc. Technical achievements can only be made when covering all aspects of innovation. Supporting customers throughout the product lifecycle through our emphasis on design for reliability (DfR) practices. After testing the entire set on the respondents, you calculate the correlation between the two sets of responses. Reliability is extremely design-sensitive. I am a material scientist & reliability engineer with 15 years’ engagement with blue-chip global multinationals in the areas of research & development, semiconductors manufacturing, telecommunications reliability and laboratory start-up, management and analysis. A company is producing a new chemical product. Upcoming SlideShare. Design for. Design for Reliability. DfR: Design For Reliability. Drawing standards ,Drawing … The design of the special hammer mill with the drying function is already described and explained by examples in [4] These examples are cited and the design of the special hammer mill augmented with comminution in this article Case 1 – Drying determines size The special hammer mill designed as an example for drying in [4] has a throughput of 50 t/h and dries limestone from 6 % to 1 % The following are the basic types of design objectives. Split-half reliability: You randomly split a set of measures into two sets. Studies have shown that more than 60% of an asset’s reliability, and therefore total cost of ownership, are determined during the design, build, installation and commissioning phase. When you do quantitative research, you have to consider the reliability and validity of your research methods and instruments of measurement.. 1.
