Modern Russian timber industry is increasingly facing the problem of raw material shortage. The country has enough stock of root wood, however, a combination of objective factors does not allow calculated cut to be fully used. One of these factors is the transport inaccessibility of root wood. In this regard, a SWOT analysis of traditional transport modes used in the transportation of wood was performed, the strengths and weaknesses of each mode of transport were identified. It is proposed to use aircraft, namely airships as an alternative for transporting wood and other necessary kinds of cargo in the timber industry. Airships can significantly reduce the cost of transportation in the conditions of inaccessible taiga. The developed methodological approach allows us to justify the effectiveness of this type of transportation of products of forestry enterprises.

Relevance. Russia currently ranks third in terms of global gold extraction and production, and the Urals is considered the birthplace of gold mining in Russia. Gold supply of Ural enterprises nowadays makes up 20–30 years of underground mining and 30–40 years of opencast mining. Reserves increment in Russia is mostly observed at primary deposits, while extraction from placers decreases continually. At the same time, gold prices rise creates prerequisites for the involvement of reserve gold fields into operation. Insufficient financial resources often make the development of new fields impossible; access to the most promising projects, the highly competitive gold fields, is the first priority for potential investors. Research aim is to develop a methodological approach to the assessment of competitive gold fields at the stage of pre-investment study and its approval in the conditions of certain fields. Research methodology includes the benchmarking method, analogue method, and the techno-economic assessment. Results. In the course of research the main obstacles for the development of new gold fields were revealed. It has been proved that the crucial aspect of miners’ competitive advantages is the cost of crude minerals based on in-place reserves and non-commercial reserves, hard rock and other rock in dumps, valuable components in tailings, etc. A formula calculating aggregated cost of the object is proposed, and the competitiveness of the revived Peshchernoe gold field is compared with three newly developed fields of Altyntashskoe, Shilovskoe, and Iagodnoe. Based on the basic indicators of field mining, the cost of mineral raw material was calculated making it possible to rank the compared fields as far as the degree of competitiveness is concerned. Summary. The analysis has shown the gradual deterioration in the quality characteristics of gold fields with the accumulation of refuse mass. Institutional barriers and insufficient financial resources of subsoil users prevent from introducing new fields. Small and medium-sized mining enterprises’ competitive growth requires: introduction and development of land provision declarative principle for geological exploration; simplified procedure of timberland registration for subsoil use; introduction of tax benefits and simplification of subsoil usage procedures as for technogenic objects; creation of favorable investment environment; improved mechanisms aimed at integrated cluster development.

The timber industry is an important intersectoral segment and an element of many production chains. The products of this industry are the raw material base for operation of many units of manufacturing and other economic activities. The purpose of the article is to conduct a comparative assessment of the cross-sectoral links of the Ukrainian timber industry, and to draw relevant analytical conclusions. The main need for assessing the cross-industry relationships of the timber industry is to determine the match and the reciprocal impact of supply and demand on woodworking products. For this purpose, the structure of output and costs (intermediate consumption) of the woodworking industry of Ukraine, Poland, Germany and other EU countries were compared. The information base of the study was the cost-release tables. An empirical study performed by the author reveals that the structure of consumption of timber products with industrial purposes in Ukraine essentially differs from the analogous structure in Poland and Germany by relatively small shares of construction and furniture industry. The revealed structural differences in cross-sectoral links of the timber industry are a core reason explaining why the consumption of timber products by the Ukrainian economy is six times lower than the Polish economy and more than twenty times lower than the German one. As a result, the supply of domestic furniture enterprises and construction sector with input resources is still an empty niche for the domestic timber industry, although a promising one.        According to the analysis of the cost structure and dynamics in timber industry of Ukraine, it was found that the cost level of domestic woodworking is the highest among EU countries. This is largely explained by the significant differences in the cost structures (intermediate consumption) of the timber industry of Ukraine and the EU. The latter is dominated by the share of timber products, while in Ukraine it tends to decrease. Also, during 2014–2017, the share of agricultural and forestry products increased in the structure of expenditures of the domestic timber industry, while the share of products and services of retail chains decreased. As a result, there was a decrease in the degree of processing of timber raw materials and deterioration in the manufacturability of production. Hence the need to transform the structure of output in timber industry in a way to increase the output of products for the construction and furniture industries, as well as creating organizational, economic and institutional legal conditions that would contribute to the growth of demand for such products in the domestic and foreign markets.

The components of value are determined. The ranking of factors, which influence the cost of buildings the monuments of architecture, is carried out. It is proved that such factors as the historical and artistic value of a buildings-monuments increase the value of the object of estimation and, at the same time, make expensive assessments, substantial expenses for restoration, repair and maintenance. It is substantiated that the prestige of the architectural monument increases the income from the use of commercial premises located in it. However, the more unique a monument, the more encumbrances and restrictions exist in the implementation of any transaction, in the conduct of economic activity in the premises that are located in such a building. The variant of classification of architectural monuments according to the method of use is suggested. The peculiarity of application of three generally accepted in the world practice of estimation of methodical approaches to determination of cost of architectural monument is analyzed. The main advantage of the cost approach is the ability to accurately determine the value of low-performing markets. Without cost analysis it is impossible to make informed decisions about the feasibility of projects for the reconstruction of architectural monuments. However, it is virtually impossible to determine accurately the cost of materials and construction technologies that existed at the time of construction of the monument. A comparable approach can only be used when assessing the premises located in buildings-monuments of urban background construction. In this case, the comparative approach will have a complementary character with respect to the results obtained by other approaches. It is proved that the use of an integral coefficient that takes into account the value of an architectural monument as an object of cultural heritage does not affect the final value of the value of the commercial premises in which it is located. It is substantiated that the main methodological approach for estimating the value of commercial premises located in monuments is the income approach. The main criterion for investment attractiveness of commercial real estate is profitability. In determining the value through the use of a return approach, in addition to a retrospective analysis, possible scenarios for future activities are modeled.

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.

For twenty decades, there is a visible ever forward advancement in the technology of mobility, vehicles and transportation system in general. However, there is no "cure-all" remedy ideal enough to solve all life problems but mathematics has proven that if the problem can be determined, it is most likely solvable. New methods and applications will keep coming to making sure that life problems will be solved faster and easier. This study is to adopt a mathematical transportation problem in the Coca-Cola company aiming to help the logistics department manager of the Asejire and Ikeja plant to decide on how to distribute demand by the customers and at the same time, minimize the cost of transportation. Here, different algorithms are used and compared to generate an optimal solution, namely; North West Corner Method (NWC), Least Cost Method (LCM) and Vogel’s Approximation Method (VAM). The transportation model type in this work is the Linear Programming as the problems are represented in tables and results are compared with the result obtained on Maple 18 software. The study shows various ways in which the initial basic feasible solutions to the problem can be obtained where the best method that saves the highest percentage of transportation cost with for this problem is the NWC. The NWC produces the optimal transportation cost which is 517,040 units.

Roundabout implementations at traditional intersections have been shown to be effective at reducing severe crashes. Roundabouts have also been implemented at interchange ramp terminals; however, limited research is available. In this study, 25 roundabout ramp terminal implementations were evaluated. The methodological approach consisted of Empirical Bayes for safety effectiveness and crash cost changes, crash type weighted distribution, crash rate analysis of bypass configuration, and cost of implementation. Roundabouts were effective at reducing fatal and injury crashes when replacing existing interchange diamond ramp terminals: 65% reduction for roundabouts replacing stop-controlled ramp terminals and 41% reduction for roundabouts replacing signal-controlled ramp terminals. Observed crash type weighted distributions are provided to visualize the frequency and location of crashes within roundabout ramp terminals for design considerations. Exit ramp and outside crossroad approaches with right-turn bypass showed significantly lower crash rates than designs without bypass. The crash cost analysis showed that roundabouts replacing diamond ramp terminals yielded crash cost savings of between $95,000 and $253,000 per site per year (69% to 54% decrease in crash costs). Considering crash costs savings only, the cost of implementation should be less than $1.9 million for a roundabout replacing a stop-controlled ramp terminal and less than $5.1 million for a roundabout replacing a signal-controlled ramp terminal to accomplish benefit-cost ratios greater than one for a service life cycle of 20 years. Costs are in 2019 dollars.
