Economic design of (X)over-bar and R charts under Weibull shock models
(Wiley-Blackwell, 2000-03-01)
This paper considers the problem of a continuous production process where both the mean and variance are simultaneously monitored by an (X) over bar chart and R chart respectively, and generalizes the model of Costa (IIE ...
Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes
(Chapman Hall Ltd, 1993-11-01)
A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the ...
Economic design of Shewhart control charts for monitoring autocorrelated data with skip sampling strategies
(Elsevier B.V., 2014-05-01)
On-line monitoring of process variability is strategic to achieve high standards of quality and maintain at acceptable levels the number of nonconforming items. Shewhart control charts are the simplest Statistical Process ...
Economic-statistical design of the (X)over-bar chart used to control a wandering process mean using genetic algorithm
(Pergamon-Elsevier B.V. Ltd, 2012-12-01)
This research considers the process mean wanders according to a first-order autoregressive model. During the in-control period the process mean wanders around its target value, and after the assignable cause occurrence, ...
Economic design of a Vp X̄ chart
(2001-12-01)
We develop an economic model for X̄ control charts having all design parameters varying in an adaptive way, that is, in real time considering current sample information. In the proposed model, each of the design parameters ...
Double-objective economic statistical design of the VP T-2 control chart: Wald's identity approach
(Taylor & Francis Ltd, 2014-10-01)
Research has shown that applying the T-2 control chart by using a variable parameters (VP) scheme yields rapid detection of out-of-control states. In this paper, the problem of economic statistical design of the VP T-2 ...
Economic design of two-stage (X)over-bar charts: the Markov chain approach
(Elsevier B.V., 2005-01-28)
When the (X) over bar chart is in use, samples are regularly taken from the process, and their means are plotted on the chart. In some cases, it is too expensive to obtain the X values, but not the values of a correlated ...
O papel do designer contemporâneo a partir das contribuições europeias na formação do profissional
(2014)
This article presents a reflection on the profession of designer from the historical period for the pre-industrial revolution approaching the figure of the industrial designer in France and emphasizes the special attention ...
Optimal economic strategy for the multiperiod design and long-term operation of natural gas combined cycle power plants
(Elsevier, 2012-09)
Optimal power plant designs are achieved by means of a proposed multiperiod non-linear programming formulation that utilizes the net present value as objective function, while construction, operation and dismantling of the ...
Economic and environmental evaluation of design for active disassembly
