Intelligent Model

A man-made catastrophe is considered as an information display of catastrophic development of events in the management system, a peculiar projection of  a man-made catastrophe on the information plane. The paper presents an intellectual model, considers dynamics and ranges of emergency changes in management system parameters, assesses potential risks and  threats  of  catastrophe  emergence.  It  has been  shown  that  at  the  macro-structural  level  for  semantic   description of a catastrophe, it is quite effective to use a tree-like network of scenarios, which displays the conceptual scheme of the subject and problem areas of the catastrophe and is based on judgments of experts, their experience and intuition. This allows probabilistic methods  to  assess  potential  risks  of  a catastrophe using two quantitative indicators: risk (probability) level of  phenomenon occurrence at a certain control point of time and the volume of the expected material loss. It has been suggested that for assessment of possible microstate the fuzzy logic should be applied for each critical object parameter, tolerance limits and functions of affiliation with the fields of fail-safe object functioning should be set by expertise, migration trajectories of relative parameter values should be monitored and terms of their forced return to the working field of regular functioning should be duly provided. Quantitative indicators having imprecise origin have been introduced in the intelligent model of potential risks to assess dynamics of catastrophe threat. One of these indicators is the expert level of catastrophe occurrence during migration of a group of abnormally dangerous parameters of a technical object. The time interval has also been considered which is measured from the current moment to the expected moment of catastrophe occurrence at the preset maximum permissible level of catastrophe threat.

In Korea, there are four major rivers which are the most important water resources for 45 million peoples. To preserve the water quality, several water management policies had been adapted but they had been not successful because of focusing only on point source pollutants. With the establishment of the special act for four major rivers in 2002, which defined four watersheds, the watershed management was regularized. A Total Maximum Daily Loads (TMDLs) management system was introduced to control point and non-point source pollutants, and has been implemented for three major river watersheds from 2002 except the Han-river watershed, which is adopting the system voluntarily. This paper provides an overview of TMDLs management system and the implementation process and its progress in Korea. Also the next step for improving the management system is discussed.

The authors of the article explore the problem of introducing process and risk-oriented thinking in national organizations. In 2000 the International Organization for Standartization, ISO, announced process approach as the basis principle of management in any organization. It became the embodiment of Deming’s postulate who recommended to consider any activity as a technological process. The authors show the practicability of transition from the functional structure of an organization to integrated process. New ISO 9000:2015 standards reflect presentday challenges and require that organizations should carry out risk assessment and accounting. One of the key objectives of the quality management system is to act as the prevention tool. Preventive action lies in using riskoriented thinking in formulating requirements to the quality management system. The authors introduce the system analysis method in risk management to reveal potential risks and plan preventive action.

ResumenLa variabilidad de los alimentos tradicionales producidos de manera artesanal es admisible, pero su inocuidad debe garantizarse. La ejecución de Buenas Prácticas de Manufactura (BPM) es fundamental para la construcción de sistemas de gestión de la inocuidad como el Análisis de Riesgos y Puntos Críticos de Control (HACCP) e ISO-22000-Food Safety Management System. El cumplimiento de este tipo de prácticas en la producción de alimentos tradicionales en México es escaso. Tomando al queso de Poro, como ejemplo de este tipo de alimentos, el presente documento describe las condiciones y controles de su proceso de producción. Ello como el primer paso para documentar la factibilidad de implementar sistemas de gestión de la inocuidad. Esto es dado que la legislación en México permite la comercialización de este tipo de quesos si su producción cumple con controles basados en BPM.AbstractThe variability of hand-made traditional food products is admissible, but food safety must be guaranteed. The accomplishment of Good Manufacturing Practices (GMP) is essential to implement food safety management systems as the Hazard Analysis and Critical Control Point (HACCP) system and the ISO-22000-Food Safety Management System. The fulfillment of these practices in the manufacture of traditional food products in Mexico is limited so, taking Poro cheese as an example of this kind of food products, the present document is intended to describe Poro cheese’s production controls and conditions as the first step to evaluate the feasibility to implement a food safety management system, since Mexico’s regulation allows the commercialization of these kind of cheeses if their production process complies with GMP.

In this study, a coupled coal and power management model is developed based on an inexact fuzzy-queue programming method. The model is applied to a case study of coupled coal and power management system. The results indicate that the developed model can afford reasonable measures for solving coal-blending and coal-resources-allocation problems in coupled coal and power management system. It is useful for (a) standardizing coal supply, (b) improving efficiencies of the boilers, and (c) reducing emissions of air pollutants for meeting local air-quality targets. Potential risks associated with coal shortages and instability due to property variations from multiple sources can also be highly lowered through diversifying coal sources. Moreover, it can handle queue problems and multiple uncertainties exist in coupled coal and power management activities. Thus, it can help decision makers obtain optimal coal-blending schemes and coal-allocation patterns.

ABSTRACTHACCP has been known as a system that uses a systematic and preventive approach that is shown to biological, chemical and physical hazards through anticipatory and preventive measures by no relying on inspection and testing on the final product. The application of HACCP is not only for the food industry but can be applied to the catering industry, catering services and food at hotels and restaurants. For this reason, modern food companies really need to determine quality standards for the consumers they serve. The purpose of this study was to analyze the application of HACCP on aviation food products (Aerofood ACS SUB) by identifying potential hazards and applying Critical Control Points (CCP). The methods are 1) observation of Critical Control Points (CCP) performed at receiving (CCP 1), chiller and freezer (Storage) (CCP 2), cooking (CCP 3), blast chilling (CCP 4), portioning (CCP 5). 2) Microbiological sampling consisting of random raw material samples at each arrival, hand swab samples randomly in the production and operational areas, swab equipment samples were also taken according to random, Dry good samples were taken randomly in storage, random ice cube samples , water tab samples are taken according to the sample. The company has HACCP planning as a guide for all processes that will take place within the company. All are based on the principles of HACCP for the whole process. The implementation of critical control points is in 5 places, namely receiving, storage, cooking, chilling and portioning blast. At each of these critical points, the standard critical temperature is different. Materials that do not meet the standards are rejected for further processing. In terms of microbiological hazards, it is checked by testing samples on foodstuffs, ready to eat food, dry good, air test, hand swab, production equipment, water and ice cube. The implementation of each sample test has been determined by PT. Aerofood ACS Surabaya based on standard procedures. If the results of checking is not the standards, repairs are handled or changes in the flow of handling procedures.

To ensure the reliable functioning of a technical object, it is necessary to predict its state for the upcoming time interval. Let the technical state of the object be characterized at a certain point in time by a set of parameters established by the technical documentation for the object. It is assumed that for certain values of these parameters, the object may be in a good or faulty state. It is required by the values of these parameters to estimate the state of the object in the upcoming time interval. Supervised machine learning methods can be applied to solve this problem. However, to obtain good results in predicting the state of an object, it is necessary to choose the correct training model. One of the disadvantages of machine learning models is high bias and too much scatter. In this paper, to reduce the scatter of the model, it is proposed to use ensemble machine learning methods, namely, the bagging procedure. The main idea of the ensemble of methods is that with the right combination of weak models, more accurate and robust models can be obtained. The purpose of bagging is to create an ensemble model that is more reliable than the individual models that make up it. One of the big advantages of bagging is its concurrency, since different ensemble models are trained independently of each other. The effectiveness of the proposed approach is shown by the example of predicting the technical state of an object by eight parameters of its functioning. To assess the effectiveness of the application of ensemble machine learning methods for predicting the technical state of an object, the quality criteria of binary classification are used: accuracy, completeness, and F-measure. It is shown that the use of ensemble machine learning methods can improve the accuracy of predicting the state of a technical object by 4% –9% in comparison with basic machine learning methods. This approach can be used by specialists to predict the technical condition of objects in many technical applications, in particular, in aviation.

The purpose of the article is to identify the typical risks of participatory budgeting projects within the framework of the most common regional practice introduced in more than 40 constituent entities of the Russian Federation - a program to support local initiatives and the formation of measures to minimize their occurrence as part of the monitoring function implemented by various stakeholders. Local government bodies, executive authorities of the constituent entity of the Russian Federation, the population of the municipality - the territory of the project are identified as stakeholders for the participatory budgeting projects under consideration. The main element of the research methodology was the structural level method, which allows us to consider the risks of projects supporting local initiatives as an element of the economic system and economic level of public administration in the subject of the Russian Federation. The article clarifies the concept of “project risk management” through the systematization of the economic categories included in it, such as risk, threat, uncertainty, factors of uncertainty and chance, project risk, management system. As a prerequisite for the functioning of the management system, the authors noted the need to take into account risk-forming factors and their sources, as well as elements of uncertainty. The phases and stages of the life cycle of projects supporting local initiatives and typical risks within each of the elements are identified. Measures have been developed to minimize the possibility of the onset of risks of projects supporting local initiatives that can be implemented by various stakeholders as part of the management function “control”. The significance of the identity of representatives of local communities for the implementation of projects supporting local initiatives and minimizing their risks is substantiated. The results of the study can be embedded in the activities of public authorities at the state and municipal levels, of interest to scientists in the field of economics and management.
