Recent studies proved that variable parameters (VP) X ̅ control charts not only detects process mean shifts quicker than the classical X ̅ control chart but also has better economic properties. Furthermore, like most papers in control chart design, the fundamental assumption is that process data are normally distributed. Nevertheless, process quality variables may not be normal in application. In this paper, we investigate the economic statistical design of the VP X ̅ control chart when the underlying process distribution is non-normal. We illustrate the design procedure and perform a sensitivity analysis on the process and cost parameters based upon the degrees of skewness and kurtosis of the population using an industrial application.

Eighteen of 91 seven- to nine-month-old Belgian white and blue double-muscled male fattening cattle developed typical signs of shipping fever. They were all injected intramuscularly once a day for three days with 5 mg/kg of enrofloxacin, and in addition nine selected at random were injected intramuscularly five times at 12 hour intervals with 0.1 mg/kg of metrenperone, a 5-hydroxytryptamine blocker, the other nine receiving a placebo. During the outbreak of shipping fever metrenperone showed effective antipyretic properties, and all the calves treated with it made a complete recovery. Moreover, during the 360 day fattening period following the outbreak, the cattle treated with metrenperone gained on average 45.4 kg more weight than the control cattle. [less ▲]

The tourism can hold a decisional role in the development of an area that does not have access to remarkable economic resources and has the capacity to contribute decisively to the exploitation of specific natural and antropic resources (mineral water, sediment, proper areals for sport or recreative activities, etc.) wich atract the touristic fluxes and lead to the apparition and development of the locality as a trousitic resort. In this context, the work aims to highlight the contribution and impact of the touristic activities to the socio-économic development of the Vatrea Dornei area [less ▲]

The Hotelling’s T2 control chart, is the most widely used multivariate procedure for two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding T2 values has been proved to have a very good performance on detecting small to moderate shifts when it is compared to the original T2 control chart . Moreover, it has been shown that the VSI scheme is more economical than the classical one. This paper studies the economic consequences of a new control scheme named variable sampling intervals and control limits (VSICL) in that the sampling interval h and control limit k vary between minimum and maximum values while keeping the sample size fixed over time. We apply the cost model proposed by Costa and Rahim [8]. Furthermore, we assume that the length of time that the process remains in control is exponentially distributed which allows us to apply the Markov chain approach for developing the cost model. We apply genetic algorithm to determine the optimal values of model parameters by minimizing the cost function. Finally, both VSI and VSICL T2 control charts are compared with respect to the expected cost per unit time. [less ▲]

We evaluated the cost effectiveness of a decision-support system (DSS) developed for assessing in real time the risk of progression of the main fungal diseases (i.e., Septoria leaf blotch, powdery mildew, leaf rusts and Fusarium head blight) of winter wheat in the Grand-Duchy of Luxembourg (GDL). The study was conducted in replicated field experiments located in four agricultural locations (representative of the main agro-ecological regions of the country) over a 10-year period (2003-2012). Three fungicide spray strategies were compared: a single DSS-based system and two commonly used spray practices in the GDL, a double- (2T)- and a triple- spray (3T) spray treatment; there was also a non-treated control. In years with a high disease pressure, the DSS-based recommendation resulted in protection of the three upper leaves comparable to that achieved with the 2T and 3T treatments, with significant grain yield increases (P > 0.05) compared to the control (a 4 to 42% increase, depending on the site and year). Overall, the financial gain in treated plots compared with the control ranged from 3 to 16% at the study sites. Furthermore, in seasons when dry weather conditions precluded epidemic development, no the DSS-basedDSS recommended no fungicide spray was recommended, reducing use of fungicide, and thus saving the cost of the product. The gain in yield for the 2T and 3T plots (compared with control) did not necessarily result in a financial gain during the duration of the experiment. This study demonstrates the potential advantages and profitability of using a DSS -based approach for disease management. [less ▲]
