In some business applications, the transaction behavior of each customer is tracked separately with a customer signature. A customer’s signature for buying behavior, for example, may contain information on the likely place of purchase, value of goods purchased, type of goods purchased, and timing of purchases. The signature may be updated whenever the customer makes a transaction, and, because ...

Multivariate control charts are very effective when monitoring several correlated characteristics. Proper process control consists of monitoring both mean and variability. In multivariate settings, the multivariate exponentially weighted moving average (MEWMA) is ideal to monitor the mean vector. Similarly, the recently-proposed multivariate exponentially weighted moving covariance matrix (MEWM...

Abstract In this article, an efficient mean chart for symmetric data have been presented multiple dependent state (MDS) sampling using neutrosophic exponentially weighted moving average (NEWMA) statistics. The existing charts are not capable of seizure the unusual changes threatened to manufacturing processes. control coefficients estimated symmetry property Gaussian distribution uncertain envi...

BACKGROUND As gait speed and transfer times are considered to be an important measure of functional ability in older adults, several systems are currently being researched to measure this parameter in the home environment of older adults. The data resulting from these systems, however, still needs to be reviewed by healthcare workers which is a time-consuming process. METHODS This paper prese...

i ABSTRACT There has been much research involving simultaneous monitoring of several correlated quality characteristics that rely on the assumptions of multivariate normality and independence. In real world applications, these assumptions are not always met, particularly when small counts are of interest. In general, the use of normal approximation to the Poisson distribution seems to be justif...

Overcrowding in emergency departments (EDs) is a primary concern for hospital administration. They aim to efficiently manage patient demands and reducing stress the ED. Detection of abnormal ED (patient flows) systems aids managers obtain appropriate decisions by optimally allocating available resources following attendance. This paper presents monitoring strategy that provides an early alert w...

Gula Merah berasal dari air nira yang disadap langsung pohon kelapa dan kemudian dilakukan proses memasak. Perubahan musim memberikan dampak berupa dihasilkan oleh tidak stabil karena itu kuantitas produksi serta penjualan gula merah juga terdampak. Adanya permasalahan tersebut maka penelitian ini membahas tentang analisis forecasting di Kecamatan Jatilawang menggunakan Metode Weighted Moving A...

This paper proposes a novel algorithm for solving discrete online learning problems under stochastic constraints, where the leaner aims to maximize the cumulative reward given that some additional constraints on the sequence of decisions need to be satisfied on average. We propose Lagrangian exponentially weighted average (LEWA) algorithm, which is a primal-dual variant of the well known expone...
