Data-driven Soft Sensors in the process industry
In the last two decades Soft Sensors established themselves as a valuable alternative to the traditional means for the acquisition of critical process variables, process monitoring and other tasks which are related to process control. This paper discusses characteristics of the process industry data which are critical for the development of data-driven Soft Sensors. These characteristics are co...
متن کاملData Driven Approach to Variable Selection and Design of Soft Sensors in Industry
This paper discusses the application of statistical techniques to identify soft sensor models between the process quality variables, whose online measurements are not available in real time, and the process variables measured in real time. The methodology is illustrated through the application of the Canonical Variate Analysis for building soft sensors to predict hydrocarbon compositions in the...
متن کاملDynamic data driven simulation with soft data
Dynamic data driven simulation dynamically assimilates observation data at runtime to improve the simulation results. Typically, the observations are “hard data” that are data collected from sensors. In this paper we consider dynamic data driven simulation with soft data, which are data coming from human reports. Compared with the quantified hard data, soft data are qualitative, fuzzy and subje...
متن کاملData Mining for the Chemical Process Industry
Advancements in sensors and database technologies have resulted in the collection of huge amounts of process data from chemical plants. A number of process quantities such as temperature, pressure, flow rates, level, composition, and pH can be easily measured. Chemical processes are dynamic systems and are equipped with hundreds or thousands of sensors that generate readings at regular interval...
متن کاملDescriptive Explanation of the Process of Commercial Soft Technology Diffusion in Iran's Oil Industry Using Grounded Theory
The purpose of this study is to describe the process of commercial soft technology diffusion in Iran’s oil industry. The study employed grounded theory and deeply interviewed 19 experts in Iran’s oil industry. According to the analysis of conducted interviews and applying open, basic and selective coding. 785 final codes, 184 concepts and 71 sub-themes were extracted. The Process for the commer...
