| Abstract | Currently, there are many situations in industry where simultaneous monitoring and control of two or more related quality characteristics of a product or a process becomes necessary. Independent monitoring of these kinds of quality characteristics can be very deceptive. Conventional multivariate control charts have been used to monitor and control the multivariate quality characteristics. However, these types of charts are not useful tools when the quality characteristics of a product or process are linguistic or fuzzy. Hence, fuzzy Hotelling’s T 2 chart (F-T 2) and fuzzy multivariate exponentially weighted moving average (F-MEWMA) control chart have been used to monitor these processes. In this paper, a fuzzy multivariate cumulative sum (F-MCUSUM) control chart is developed by means of the fuzzy set theory. Through a numerical comparison via a simulation study, the performance of the developed control approach is investigated on the basis of the average run length (ARL) in various out-of-control scenarios. When small shifts make the process out of control, the F-MCUSUM control chart is almost two times quicker than the F-T 2 and F-MEWMA control charts in detecting shifts. The results of numerical comparison indicate better performance of developed multivariate control approach in detecting small- and medium-sized shifts in the process. A case study in food industry is utilized to show the applicability of the proposed approach and the interpretation of the out-of-control signals. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
