[ 1 ] - A Bayesian Approach for the Recognition of Control Chart Patterns
In this research, an iterative approach is employed to recognize and classify control chart patterns. To do this, by taking new observations on the quality characteristic under consideration, the Maximum Likelihood Estimator of pattern parameters is first obtained and then the probability of each pattern is determined. Then using Bayes’ rule, probabilities are updated recursively. Finally, when...
[ 2 ] - A Queuing Model for Stochastic Location-inventory Problem with Waiting Cost Considerations
This paper presents a three-level supply chain model which includes single supplier, several distribution centers and sets of retailers. For this purpose, by adopting the queuing approach, a mixed nonlinear integer programming model is formulated. The proposed model follows minimizing the total cost of the system by determining: 1) the number and location of distribution centers between candida...
[ 3 ] - Pattern Recognition in Control Chart Using Neural Network based on a New Statistical Feature
Today for the expedition of the identification and timely correction of process deviations, it is necessary to use advanced techniques to minimize the costs of production of defective products. In this way control charts as one of the important tools for the statistical process control in combination with modern tools such as artificial neural networks have been used. The artificial neural netw...
[ 4 ] - A New Statistical Approach for Recognizing and Classifying Patterns of Control Charts (RESEARCH NOTE)
Control chart pattern (CCP) recognition techniques are widely used to identify the potential process problems in modern industries. Recently, artificial neural network (ANN) –based techniques are very popular to recognize CCPs. However, finding the suitable architecture of an ANN-based CCP recognizer and its training process are time consuming and tedious. In addition, because of the black box ...
[ 5 ] - Identify the challenges of leadership in hospitals
Background: In this study, we seek to identify the challenges of leadership role in physicians. For physicians facing the challenge of being able to appear only as a leader is fraught with challenges. Because they have to follow the clinical duties of the patients at the same time. In fact, we face five major challenges along the way. This article introduces these five challenges and solutions ...
