Stochastic model to predict boron concentration with different inflow and interval irrigation in greenhouse

This study presents the development of a stochastic modelling system and a laboratory works on the greenhouse scale for estimating the concentration of boron in controlled irrigated-paddy plants. The model was developed based on Object Oriented Programming (OOP) Python 3.6. The stochastic model is developed to predict boron concentration through different treatments (different inflow and interval irrigation) inside the greenhouse. There were three treatments of the experiment in greenhouse scale: the buckets filled using full of open inflow in bucket one, the buckets filled using a half of open inflow in bucket two, the buckets filled using a quarter of open inflow in bucket three. The study used integration data using Odeint python package, Hargraves model, and chemical kinetics to estimate the boron concentration. The result shows that bucket two and bucket three have higher boron concentration than bucket one based on laboratory experiment. In this study, the simulation approaches show performances which are satisfactory to predict boron concentration up to three second in the buckets.

An intelligent tutoring system for a power plant simulator

In this paper, an intelligent tutoring system (ITS) is proposed for a power plant simulator. With a well designed ITS, the need for an instructor is minimized and the operator may readily and efficiently take, in real-time, the control of simulator with appropriate messages he(she) gets from the tutoring system. Using SIMULINK and based on object oriented programming (OOP) and C programming language, a fossil-fuelled power plant simulator with an ITS is proposed. Promising results are demonstrated for a typical power plant.

A new FMS simulator with object-oriented-programming techniques

With the advance of research, design and operation of flexible manufacturing systems (FMS), new requirements have been presented for FMS simulators. These new requirements are high modelling efficiency, high model validity and credibility, more user-friendly features, real control and scheduling logic similar to a real FMS, and effective and correct analysis of results, etc. In this paper, a new FMS simulator (FMSSIM) based on object-oriented-programming (OOP) and some new techniques is introduced. The new techniques include: (i) fully interactive graphical modelling technique, with which the simulation modelling only needs 2–4 h to complete and the model data are highly consistent and accurate; (ii) real FMS-like simulation control and scheduling, with which various control and scheduling algorithms such as AI-based heuristic scheduling can be easily implemented; (iii) the Intelligent Evaluator, with which the efficiency and accuracy of the evaluation process can be improved. Practical use has shown that the FMSSIM has a good performance in modelling, operation and evaluation, meeting the new requirements for a modern FMS simulator.

An Intelligent design environment for conceptual process design

Conceptual process design is a multiagent, distributed problem-solving activity that can be significantly enhanced with the aid of several individual intelligent ssytems. It is quite difficult to develop such intelligent systems on the basis of existing expert-system shells because of the complexity of conceptual process design. In this paper, the characteristics and requirements of conceptual process design are first analyzed, and then an intelligent design environment (Meta-COOP) for conceptual process design is presented. Meta-COOP is based on object-oriented programming (OOP) techniques and coded in C ++. This environment provides such distinct features as the integration of various knowledge-representation and inference methods, and deals with multimedia information. An intelligent system for the conceptual design of heat exchanger networks (IDIS-CDHEN) provides an application of this intelligent design environment, and a demonstration of its methodology.

Implementing i-state configuration models for population dynamics: an object-oriented programming approach

Abstract Demographic models describe population dynamics in terms of the distribution of individuals among categories (e.g., age or size classes); such models are called i-state distribution models . In contrast, i-state configuration models describe population dynamics by simulating the birth, development, and eventual death of each individual in the population. Such models (also referred to, less precisely, as individual-based models ) are necessary when interactions among individuals make the assumptions of i -state distribution models untenable. The basic components of an i -state configuration model are a set of individuals (each characterized by its i -state), an interaction structure, and an environment. Each of these components changes dynamically as a function of the others. The implementation of i -state distribution models is familiar; here we present a general framework, based on object-oriented programming (OOP), for the numerical implementation of i -state configuration models. The individuals, interaction structure, and environment are all defined as objects. A special object called the simulator transfers information among these objects as needed. The properties of OOP (data protection, inheritance, polymophism, modularity) lend themselves naturally to i -state configuration simulations.
