Integrated optimisation of short- and medium-term planning in underground mines

ABSTRACT This article describes a new model aiming at optimising short- and medium-term underground mine scheduling. The problem complexity and the frequency at which planners must revise these schedules are among the primary motivations for developing such a model. To address this problem, a Mixed Integer Programming model is proposed with a flexible time discretisation to accurately represent both shortand medium-term operational constraints in a single model. The results of a preliminary mathematical formulation are presented with in-depth analyses. Further, an improved formulation is presented with associated results and benefits. Extensive experiments with scenarios similar to long-term planning show promising results for the improved formulation. Among other things, these results show that the modified formulation makes it possible to solve for scenarios that include a large number of activities and locations while generating more applicable solutions.

A Review of Predictive and Prescriptive Offshore Wind Farm Operation and Maintenance

Offshore wind farms are a rapidly developing source of clean, low-carbon energy and as they continue to grow in scale and capacity, so does the requirement for their efficient and optimised operation and maintenance. Historically, approaches to maintenance have been purely reactive. However, there is a movement in offshore wind, and wider industry in general, towards more proactive, condition-based maintenance approaches which rely on operational data-driven decision making. This paper reviews the current efforts in proactive maintenance strategies, both predictive and prescriptive, of which the latter is an evolution of the former. Both use operational data to determine whether a turbine component will fail in order to provide sufficient warning to carry out necessary maintenance. Prescriptive strategies also provide optimised maintenance actions, incorporating predictions into a wider maintenance plan to address predicted failure modes. Beginning with a summary of common techniques used across both strategies, this review moves on to discuss their respective applications in offshore wind operation and maintenance. This review concludes with suggested areas for future work, underlining the need for models which can be simply incorporated by site operators and integrate live data whilst handling uncertainties. A need for further focus on medium-term planning strategies is also highlighted along with consideration of the question of how to quantify the impact of a proactive maintenance strategy.

ПРОБЛЕМИ ОРГАНІЗАЦІЇ СЕРЕДНЬОСТРОКОВОГО БЮДЖЕТНОГО ПЛАНУВАННЯ НА МІСЦЕВОМУ РІВНІ

The article reveals the basics of medium-term budget planning in Ukraine, identifies key elements of this process, analyzes the problems of its implementation at the local level. The relevance of the topic of the article is due to reforms in the budget planning system and the difficulties that arise in practice. The changes that have been systematically implemented over the last three years have radically changed the approaches to the application of medium-term planning in the budget process. The established system of medium-term planning has changed not only the methodological support of the process, but also provided for changes in organizational elements, which caused difficulties and requires special attention from both theoretical and practical points of view. Among such key issues in the article are considered – the problems of forming a system of goals and priorities of strategic, medium-term and operational nature, their relationship and impact on the implementation of medium-term planning. The deadlines for developing medium-term plans and the possibility of changing them under the pressure of different conditions also need to be studied. In the context of reforming the concept of strategic planning, the role of medium-term planning and financial support for the process of achieving goals is constantly growing. The compliance of the planning process with strategic priorities needs additional attention. Particular importance is attached to the process of compliance with regulatory and legal regulation of medium-term planning at all levels. There is also a need for improvement. regulatory framework at the local level in terms of the main organizational documents of the budget process. Despite the imperfection of the regulatory framework, changes and the nature of its reform need additional attention. The article reveals the impact of the problem of staffing and information support on the effectiveness of medium-term planning. The characteristic feature of the personnel potential of the medium-term planning process is the lack of motivation of youth to work in local self-government communities, which creates a problem of personnel hunger.

Development of an approach to mediumterm volumetric scheduling of production based on the sliding windows method

This article is devoted to the development of an approach to the volumes redistribution of production and shipments for the purpose of improving the objective functions value for a medium-term production plan built by using the sliding window method. Disadvantage of sliding window method is marked, which consists in excluding the options for long-term accumulation of production from consideration, and proposes an approach to solving this problem, which made it possible to significantly reduce the proportion of contractual obligations not planned for fulfillment.

БЮДЖЕТУВАННЯ ПІД ЧАС НАДЗВИЧАЙНОГО СТАНУ У КОНТЕКСТІ ЄВРОІНТЕГРАЦІЇ ДЛЯ УКРАЇНИ

The paper examines the performance budgeting development in Ukraine with the aim of further integration its current mechanism with EU budgeting. The research on mechanism of performance budgeting in Ukraine made it possible to identify its components: the top-manager of the budgetary unit role as an administrator of budget fund; the framework of ac- countability and control for the responsibility of activities’ executors; policy as a democratic tool for setting goals due the us- ing of budgetary funds; combining the previous elements with a medium-term framework for activities to achieve the results. The effectiveness and efficiency of budgeting means the responsibility of budget managers for the result and for the method of achieving it within the justified budget allocation. Budgeting in the EU provides medium-term guarantees of budgetary alloca- tions to administrators with a preliminary list of opportunities and obstacles in obtaining results. In Ukraine, despite the prepara- tion of medium-term plans, guarantees of budget allocations for the administrator are created only for one year. The emergence of emergencies has shown the need for a medium-term framework for priority outcomes combined with additional operational response. It is proposed to divide the effective budgeting mechanism into a supporting medium-term part and a part of emer- gency budgeting, the plan for which may change at the current moment. Priorities are important in emergency budgeting, but, when they are combined with medium-term budgeting, the desired results are not lost of sight. The use of funds for emergencies requires more flexibility for the administrators activities framing. This paper offers the comparing of EU and Ukraine perfor- mance budgeting organization in medium-term planning of activities, executing the policy targets consequences and providing financing for administrators of budget units, in emergency as well. The obtained results describe the possibilities of performance budgeting will have been performed under the Ukraine integration to EU budgeting rules. The proposals on the prospects for provide further improvement in regulation of the spending unit’s planning are formulated.

Local Development Planning Process: A Policy-Level Analysis in Nepal

This study aims at assessing the process and practice of local development planning in Nepal under federal system, with the bid of analyzing the local government operation act, 2074 and local level plan formulation direction, 2075. Using the primary and secondary sources of data, the study embarks on the local development planning process under federal system of Nepal while employing a descriptive research design. Nepal has not experienced long empirical experiences on local development planning exercised under federal democratic republic and it is a totally new practice. The study argues that the local government operation Act, enacted in 2074, conceived the decentralized planning process starting from the settlement level moving up through the local government to the national level and under this all local bodies are required to prepare short, medium and long term, periodic and strategic plans. It concludes that the long term vision of 15th plan of Nepal with "Prosperous Nepal, Happy Nepali" is the foundation for upgrading high income countries by transforming Nepal into socialist oriented public welfare with a rich economy social justice and peaceful living considering local development plan as yardstick and pivot for national long term vision.

ЕКОНОМЕТРИЧНІ ПІДХОДИ ДО ПРОГНОЗУВАННЯ ФІНАНСОВОГО ЗАБЕЗПЕЧЕННЯ СОЦІАЛЬНО-ЕКОНОМІЧНОГО РОЗВИТКУ РЕГІОНУ

In the given article it is noted that the level of forecasting of processes of social development is determined by the efficiency of planning and management of economy and other spheres. Social and economic forecasting of basic trends of social development allows use of special calculation and logic methods, giving the opportunity to determine parameters of functioning of separate elements of productive forces in their interrelation and interdependence. At the current stage of regional development of the state, the forecasting of the management of social-economic processes in the region is urgent, and the need for their improvement in order to obtain effective tools for determining the main guidelines and directions of regional policy. Predictions that include scientific justification should be central to the planned decisions of state authorities and the implementation of social-economic policies in the region, to determine the main directions of its future development, place and role in the national economy. The process of forming a modern system of forecasting regional development in Ukraine took place under conditions of a large-scale state transformation and reorganization. The change in the political regime and reform of the Ukrainian economy, which began in the 1990s, led to the inversion of the role of the territory in the system of public administration. Regions that previously had very limited rights in the agricultural sector, received the right to make political, economic, social, cultural and other decisions on their own. Economic forecasting is necessary for determining ways of society development and economic resources which provide its achievement, for revealing most likely and economically efficient variants of long-term, medium term and current plans, grounding main directions of economic and technical politics, forecasting the consequences of the made decisions and measures taken at present. Application of econometric models in economics gives the opportunity to distinguish and formally describe the most significant, the most essential relations of economic variables and objects, as well as to get new knowledge about the object in the inductive way. In such model, in the simplified form, by many assumptions, the main dependence between economic indicators is determined.

Kebijakan Ekonomi Di Masa Pandemi Covid-19

COVID-19 discovered a global pandemic that gave rise to the emergence of various groups, especially the public. Inaugurated by the World Health Organization as a global pandemic, the management of COVID-19 is a challenge for countries with limited energy sources and health care systems. Citizens' understanding continues to grow along with the number of positive problems and deaths due to COVID-19 which continues to grow in a relatively short time. The ability of each country to adapt to the existing conditions during efficient and anticipatory implementation varies greatly. The policy finds an early ground that must be tested in order to be able to tackle these cases successfully. Anticipatory policy decisions related to efforts to prevent the spread of COVID-19, take action against infected patients, protect health workers, and control public awareness are carefully considered. For this reason, the Government is trying to schedule a New Normal policy so that the economic impact of the pandemic does not create a sustainable crisis. This policy is linked to planning where the Government has established programs, as well as major projects in the 2020-2024 National Medium-Term Development Plan (RPJMN). The government needs to review the medium-term plan considering that in 2020 all programs that are trying to focus on taking action against Covid-19. The government has 3 alternatives in the medium term, whether it is always quality, making moderate improvements, or changing it with a new plan with assumptions made from the Covid-19 pandemic and the consequences that accompany it.

Виконання Державного бюджету України в умовах пандемії COVID-19

The article analyzes the state of formation and efficiency of the State Budget of Ukraine. It has been established that budget expenditures exceed revenues and as a result, the budget has been formed over the last decade with a significant deficit, and the existence of a deficit leads to a movement in the "debt spiral". To implement the budget the Government is forced to borrow additional funds and attract them on acceptable terms, which has become increasingly difficult. Failure to receive the funds leads to late spending. The analysis of expenditures of the State Budget of Ukraine according to the functional classification is carried out, which testified to the main priorities of the state in modern conditions. Given Russia's aggression in the east of the country, it is logically justified to increase security and defense spending. However, it is advisable to review social expenditures, which are quite large in size and do not improve the quality of social services, on the contrary, restrain economic growth, the country's transition to an innovative model of development. In order to increase the efficiency of budget execution, the validity of macro indicators, it is advisable to introduce medium-term budget planning. Budget expenditures must be justified and balanced in order to achieve the most effective results of budget programs and the goals of the budget system of Ukraine. The study identified systemic shortcomings in the State Budget of Ukraine, which are repeated from year to year, as well as those that characterize the special year 2020 associated with the pandemic COVID-19. Emphasis is placed on the functioning of the domestic system of public financial control and its importance in reducing the volume of budget violations, the effectiveness of budget execution, promoting better functioning of the financial and budgetary system, ensuring sustainable dynamics of socio-economic development of the country.

MANAGEMENT OF XINJIANG’S OIL ENERGY AND NUCLEAR ENERGY SOURCES IN THE PEOPLE'S REPUBLIC OF CHINA (PRC) IN POST-COLD WAR

China's dependence on energy so far has been on coal. However, like other non-renewable fossil energy, the supply of coal itself is getting depleted. In addition, the PRC's dependence on coal so far has brought losses to the PRC itself, namely the high levels of carbon dioxide emissions contained in the PRC's air. This situation makes the PRC government feel the need to develop other energy sources. Considering the PRC is a country that is blessed with various energy reserves which are quite abundant, it is not too difficult for the PRC government to explore and develop these energy reserves. However, it turns out that it is not so easy to raise this issue because in some ways this energy issue has touched other sensitive aspects. For this reason, the PRC government implements an energy policy consisting of a short-term plan, a medium-term plan, and a long-term plan. The agency responsible for this is the State Planning Commission (SPC). Bringing together the supporting factors and inhibiting factors, the visible trend is that the PRC government will continue to strive to maintain its energy policy, but by making improvements that are felt to be very necessary in order to be effective. This is inseparable from the existence of the PRC's economy as well as its environment which means the existence of the country itself in the future.

It then turns to the state budget formulation and execution before discussing transparency and openness in budgeting. It concludes with a discussion of parliament’s role in the budget process and external oversight. Recommendations are made for each of these topics.

A Future Study of an Environment Driving Force (EDR): The Impacts of Urmia Lake Water-Level Fluctuations on Human Settlements

Lake Urmia, one of the world’s largest salt lakes, is rapidly losing water and drying up. This environmental hazard has raised concerns about the consequences and impact on the surrounding communities. In this paper, we use a futuristic view (horizon of 10 years based on medium-term planning) to identify the main environmental drivers in the surrounding settlements of the Urmia Lake basin. A qualitative method, based on cross-impact analysis, was used as a means of future research. We also used a Delphi-based expert panel method to collect data and extract the environmental impacts of Urmia Lake. After the three rounds of the Delphi process, the expert panel reached a high level of agreement (100%) on the top 17 environmental consequences. Then, these consequences were classified by driving force and dependency using the MICMAC method. The results show that reducing pasture area, soil and water salinity, groundwater decline and depletion, and destruction of surrounding agricultural lands play a significant role in environmental change in Urmia Lake. Overall, any small change in these variables may lead to fundamental changes in the entire system.

Comprehensive Food System Planning for Urban Food Security in Nanjing, China

Food system planning is important to achieve the goal of “zero hunger” in the UN’s 2030 Agenda for Sustainable Development (UN, 2016). However, discussion about comprehensive planning for food security is scarce and little is known about the situation in Chinese cities. To narrow this gap, this study collected and analyzed four medium-term plans and two annual plans for the “vegetable basket project” in Nanjing, China. This study examines the strategies for urban food security in Nanjing to shed light on how the city developed a comprehensive approach to food system planning over the past three decades. The evolution of incremental food system planning in Nanjing provides valuable lessons for other cities facing food security challenges and shortages of financial resources. Reducing food insecurity is an ongoing challenge for the city governments in the Global South and comprehensive planning is a useful tool for addressing the challenge of urban food insecurity.

Training aims to develop skills, knowledge, and attitudesin the process of increasing self-potential according to the needs and potential of the region. One of the useful trainings to develop regional potential is training batik making. Where the Annual Village, District Umbulharjo is one of the areas producing Craft Tourism. Kampung Tahunan has several studios that create batik products and jumputan fabrics. The potential of the area as well This is the culture of the Indonesian nation that must be preserved, namely by held a written batik training.
 Batik Kenanga Mekar is a group of beginner batik craftsmen in Tahunan Village, Umbulharjo District. This village is one of the Cultural and Tourism Conservation Areas in the city of Yogyakarta. Geographically, the Tahunan Village area is strategic so that in 2011 it was inaugurated as a Cultural Tourism Village. As a Tourism Village, there are still many things that need to be addressed by adjusting the one in the vision and mission of the Medium Term Planning (RPJM) which is to improve the welfare and empowerment of the community. To support this, the potential of the community must be maximized, so that the devotees develop one of the existing potentials by empowering the local community which will later improve the welfare of the community. The artistic potential is high and creative, besides that the community still has a lot of time left that has not been utilized so that written batik can be developed.

People-Oriented Optimization Model Of Warehouse Staff Scheduling Problem

With the development of e-commerce, China is actively promoting the construction of logistics informatization and intelligence, and simultaneously promoting the standardized and efficient development of warehousing industry, one of the important links of logistics. It is clearly pointed out in the "Medium and Long Term Plan for the Development of the Logistics Industry" issued by the State Council that "The warehousing industry is not only the main body of the traditional logistics industry, but also an important part of the modern logistics industry. In the process of material flow, the level of storage cost has a greater impact on the development of the logistics industry." This paper chooses Sinotrans Logistics Company as the research object. Sinotrans Logistics Company is the largest integrated logistics provider in China and a national 5A comprehensive logistics enterprise. The main problems in Sinotrans warehousing management include: increased operation difficulty of cross-warehouse inventory, large order volume and delayed processing, unreasonable scheduling of warehouse staff, more idle time for warehouse staff and large difference in human efficiency per hour, etc. The key elements of these problems are the work efficiency of employees. Therefore, warehouse management needs to carry out fine scheduling of warehouse staff to improve the completion rate of orders and reduce the waste of labor costs. Keywords: Warehouse staff scheduling problem, integer programming, linear regression model, people-oriented

Natural Resources as a Factor in Production of a Regional Tourist Product and in Creation of Tourist Destinations

Introduction. Geographical location of natural resources is a determinant of localization of tourism. Based on the results of the research conducted, the article studies the theoretical and practical aspects of transformation of natural resources into a factor in production and consumption of a tourist product, as well as those of formation of directions for the flow of tourists. Materials and Methods. Materials of surveys of potential tourists conducted by independent research firms, Russian and foreign scientific publications and expert assessments, as well as the results of research carried out by the author of the article were used as the information base of the study. To assess the role and place of natural resources in the production and consumption of a tourist product, content analysis, as well as structural and functional analysis were employed. Using the methods of logical interpretation, statistical data processing, tabular and graphical methods, a scheme of transformation of natural resources into a factor in production and consumption of a tourist product has been devised and the degree of consumer preference for a tourist destination has been identified. Results. The study has identified problematic aspects of the use of natural resources in tourism, one of which is the underestimation of such resources as a basic factor in production and consumption of a tourist product, which negatively affects the level of economic feasibility of tourism development programs. The role of natural resources in formation of tourist needs and directions of the flow of tourists has been revealed. Conclusions have been drawn about the growing need for tourism with the predominance of the natural component of the tourist product and about the gradual formation of preconditions for local manifestations of overtourism and tourism phobia, in particular in the resorts in the South of Russia. The author has formulated proposals aimed at improving the economic feasibility of domestic tourism development programs. Discussion and Conclusion. Availability of natural resources is the primary basic condition for production and consumption of a tourist product. Significant costs for their transformation into tourist goods increase the requirements for the level of reasonableness of managerial decisions. The research results can be applied in strategic and medium-term planning of the development of domestic tourism in Russian regions on the basis of their natural potential.

Data-driven optimization of mixed-integer bi-level multi-follower integrated planning and scheduling problems under demand uncertainty

The coordination of interconnected elements across the different layers of the supply chain is essential for all industrial processes and the key to optimal decision-making. Yet, the modeling and optimization of such interdependent systems are still burdensome. In this paper, we address the simultaneous modeling and optimization of medium-term planning and short-term scheduling problems under demand uncertainty using mixed-integer bi-level multi-follower programming and data-driven optimization. Bi-level multi-follower programs model the natural hierarchy between different layers of supply chain management holistically, while scenario analysis and data-driven optimization allow us to retrieve the guaranteed feasible solutions of the integrated formulation under various demand considerations. We address the data-driven optimization of this challenging class of problems using the DOMINO framework, which was initially developed to solve single-leader single-follower bi-level optimization problems to guaranteed feasibility. This framework is extended to solve single-leader multi-follower stochastic formulations and its performance is characterized by well-known single and multi-product process scheduling case studies. Through our data-driven algorithmic approach, we present guaranteed feasible solutions to linear and nonlinear mixed-integer bi-level formulations of simultaneous planning and scheduling problems and further characterize the effects of the scheduling level complexity on the solution performance, which spans over several hundred continuous and binary variables, and thousands of constraints.
