Variability sensitive Markov decision processes

Proceedings of the 28th IEEE Conference on Decision and Control, 1992
Considered are time-average Markov Decision Processes (MDPs) with finite state and action spaces. Two definitions of variability are introduced, namely, the expected time-average variability and time-average expected variability. The two criteria are in general different, although they can both be employed to penalize for variance in the stream of ...

Process and Process Variables

2018
This chapter covers the concepts of process, process design and operation, and process variables. Process parameters herein include mole, density, specific gravity, specific volume, flow rate, fraction, concentration, temperature, pressure, and other thermodynamic properties of the materials.

Mixture-Process Variable Experiments with Noise Variables

Journal of Quality Technology, 2003
In a mixture experiment, the design factors are mixture components whose proportions are varied, and the response variables are assumed to depend only on these component proportions. In addition to the mixture components,the experimenter may be interested in other variables that can be varied independently of one another and of the mixture components ...

Processing Time Variability

2008
In the previous chapter, an approximation for the cycle time in a system queue was developed (or waiting time in the queue for a machine). The relationship consists of four parameters.

Variables Influencing Operator Information Processing

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1963
Using two criteria, time required to react to the stimulus and performance on a simple tracking task, subjects were exposed to various levels of rate of information presentation, the number of channels through which it was presented, and the physical location and arrangement of the information media.

Monitoring Process Variability Using EWMA

2006
During the last decade, the use of the exponentially weighted moving average (EWMA) statistic as a process-monitoring tool has become more and more popular in the statistical process-control field. If the properties and design strategies of the EWMA control chart for the mean have been thoroughly investigated, the use of the EWMA as a tool for ...

RENEWAL PROCESS FOR FUZZY VARIABLES

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2007
Recently, Zhao and Liu [IJUFKS 11 (2003) 573–586] proposed a "fuzzy elementary renewal theorem" and "fuzzy renewal rewards theorem" for a renewal process in which the inter-arrival times and rewards are characterized as continuous fuzzy variables. The continuity assumption is restrictive.

Variable structure process control

[Proceedings 1992] The First IEEE Conference on Control Applications, 2003
The design of a direct control of a chemical plant based on variable structure output feedback system theory is described. The plant consists of a reactor followed by an elaborate separation system. The overall control strategy is to operate the plant at near optimum return on investment.
