Complex Objects Remote Sensing Forest Monitoring and Modeling

In this paper the concept of integrated modeling and simulation processes of the Complex Natural and Technological Object (CNTO) is presented. The main goal of the investigations consists in the practice of the predetermined modeling. The practice direction as the remote sensing forest monitoring is proposed by the authors. Here the methodical foundations of the integrated modeling and simulation, the process of CNTO operation, the technology of the remote sensing forest monitoring are considered. Principal concern is attended to the continuity of the model and object solving practical issues. More over results of CNTO remote sensing forest monitoring make it possible to adapt models of this system to changing environment conformably to the forest management.

Operational Flood Forecasting As A Web-Service.

The paper presents flood forecasting and simulation system applied to a river flood analysis and risk prediction. An advanced river flood monitoring, modelling and forecasting approach is introduced. It extends the traditional approach based on modelling of river physical processes by integration of different types of models and technologies such as input data clustering and filtering, digital maps of a relief and river terrain, data crowdsourcing, heterogeneous data processing, hydrological models for time scale modelling water flows and geo-simulation, inundation visualization and duly warning on flooding. The service-focused architecture of system of monitoring and anticipatory forecasting of floods and weak connectivity of program modules peculiar to it allows to convert developed system to a format of the cloudy application implemented as service. The paper presents the implementation using BPEL language implements the business process work hydrological model, and describes how to use the BPEL can be realized by using CASE representations continuous and independent operation of several different hydrological models and automatically provide the user with the results of an optimal model for the present time. Developed servicefocused architecture can be used for other infrastructure projects. Group of authors focuses on programmathematical and algorithmic support of research projects.

Structure Adaptation Of Models Describing Scheduling Processes In Complex Technical-Organizational System (CTOS).

In this paper, a dynamical multiple criteria model of integrated adaptive planning and scheduling for complex technical – organizational system (CTOS) is presented. Various types of CTOS are used nowadays, for example: virtual enterprises, supply chains, telecommunication systems, etc. Hereafter, we mostly interpret CTOS as the systems of the above-mentioned types. The above-mentioned CTOS peculiarities do not let produce an adequate description of control processes in existing and designed CTOS on a basis of singleclass models. That is why the concept of integrated modeling and simulation that was proposed by the authors can be useful here. Possible directions of its realization were considered in their papers and books (Okhtilev et al.,2006, Ivanov et al., 2010). Here we consider two general actual problems of the CTOS structure-dynamics investigation: the problem of selection of optimal CTOS structure-dynamics control programs at different states of the environment; the problem of structural adaptation of models describing CTOS structure-dynamics control programs.

Integrated Planning Of Supply Chain Business Processes And Disaster-Tolerance Information Systems.

This contribution proposed an original modelling and algorithmic tools for integrated (re)-planning of supply chain business processes and disaster-tolerance information systems (DTIS). The following models are jointly used: the model of DTIS recovery (modernization) management; the model of DTIS o peration control; the model of business-processes management as applied to DTIS-aided activities. The combined algorithms of integrated planning of DTIS operation and recovery (modernization) use these models and apply modern results of the control theory and operation research. The essence and novelty of modelling and integrated planning of DTIS lies in the possibility to relate optimization of business-processes goals with executive data-handling procedures, information processing, and DTIS communication. This provides joint finding of optimal businessprocesses for supply chains using DTIS and management programs for DTIS. The planning algorithms use the fundamental scientific results obtained within the modern control theory operating with complex dynamic objects with reconfigurable structure. The prototype computer program for modelling and integrated planning of supply chain processes and DTIS has been developed.

Parametric Adaptation Of Models Describing Structure-Dynamics Control Processes In Complex Technical Systems (CTS).

In this paper, a dynamical multiple criteria model of integrated adaptive planning and scheduling for complex technical system (CTS) is presented. Various types of CTS are used nowadays, for example: virtual enterprises, supply chains, telecommunication systems, etc. Hereafter, we mostly interpret CTS as the systems of the above-mentioned types. The adaptation control loops are explicitly integrated with the analyticalsimulation model. The mathematical approach is based on a combined application of control theory, operations research, systems analysis, and modeling and simulation theory. In particular, a scheduling problem for CTS is considered in a dynamical interpretation. New procedures of dynamic decomposition help to find the parameters value of models adaptation. The example demonstrates a general optimization scheme to be applied to the problem of competencies division between the coordinating and operating levels of CTS via parametric adaptation of models describing structure-dynamics control processes.

Models And An Algorithm For Multi-Criteria Synthesis Of Control Technologies Managing Information Systems Of Virtual Enterprises

Integrated information systems (IIS) of virtual enterprises (VE) were considered as objects of control. Two interrelated problems were jointly stated. The first problem lied in program management of IIS and ranking its structural states. The second one implied that control functions regulating business processes should be reallocated among elements and subsystems of IIS in a real time mode. A formal multi-criteria description of these problems was made and a combined (simulationbased) algorithm of a solution was worked out.

Simulation-Based Multi-Criteria Estimation Of Plans Stability

A general scheme of multi-criteria estimation of plans stability via simulation of complex technical systems was proposed. Main variants of input data presentation (deterministic, stochastic, and interval) were considered.
