This paper considers adaptive schemes for the simultaneous monitoring of mean and variability a multivariate normal quality characteristic. At first, we extend an already existing bivariate non-adaptive control chart to one. Then, develop several schemes, which will cover both previously newly charts. After having designed chart, eight performance measures are computed based on run length, time...

The Live Sequence Charts (LSC) language is an extension of the well-known Message Sequence Charts by means to specify liveness and to distinguish possible runs of a system from protocols that all runs should adhere to. This paper studies the expressive power of the automaton-based LSC semantics [11] in terms of temporal logic. The main result is that bonded core LSCs have an exact characterisat...

This article explained the financial innovation service product fundamental mode of supply chain finance, and explored the risk of supply chain finance. Fuzzy ordinal regression support vector machine is used to analysis the risk of supply chain finance by the index system of risk assessment, and the results were effective and could be improved in the future.

a manufacturing process cannot be released to production until it has been proven to be stable. also, we cannot begin to talk about process capability until we have demonstrated stability in our process. this means that the process variation is the result of random causes only and all assignable or special causes have been removed. in complicated manufacturing processes, such as drilling proces...

The reliability data is getting used to monitor and improve the quality of products or services. Nowadays, most of products or services are the results of processes with dependent stages referred to as multi-stage process. In these processes, the quality characteristics are affected by the quality characteristics in the previous stages, called as cascade property. In some cases, it is not possi...

background: increased heart rate is a normal physiological adaptation occurring during pregnancy. some women have severe tachycardia requiring medical attention. aim of this study is to determine the number of women with benign symptomatic palpitations who receive treatment. method: we performed a retrospective chart review of all women who were referred to our obstetric-medicine clinic for eva...

Statistical process control charts are intended to assist operators of a usually stable system in monitoring whether a change has occurred in the process. When a change does occur, the control chart should detect it quickly. If the operator can also be provided information that aids in the search for the special cause, then critical off-line time can be saved. We investigate a process-monitorin...
