Background: Coal production and marketing enterprises can significantly reduce transportation costs and improve their competitiveness by choosing appropriate road transportation companies. Methods: Based on this, a trapezoidal fuzzy SWARA-COPRAS method is proposed to select coal transportation companies. The trapezoidal fuzzy SWARA method is used to determine the index weight of coal transportation companies. The ranking of coal transportation companies is determined using the trapezoidal fuzzy COPRAS method. Results: Taking a coal production and marketing enterprise in Hubei, China as an example, the application of the trapezoidal fuzzy SWARA-COPRAS method is illustrated, and the coal transportation companies are sorted and analyzed for sensitivity. Conclusions: Compared with the results of other methods, the effectiveness and practicability of the trapezoidal fuzzy SWARA-COPRAS method are verified.

This chapter takes the Beijing-Tianjin-Hebei region as the research scope, selects coal transportation as the research object, and finds out the current situation and supply capacity of railway transportation in the context of the transportation industry's active promotion of transportation structure adjustment. The chapter chooses coal as an example, bases on the different influencing factors such as transportation distance and freight rate, combines with the current situation of railway transportation, quantitatively analyzes the superior distance and competitiveness of typical cargo railway transportation, and obtains the superior distance between railway transportation and road transportation the influence degree of various influencing factors on the sharing rate of railway transportation market. Finally, the chapter puts forward corresponding measures to improve the competitiveness of railway transportation market.

The article analyses the manner of selection an optimal building technological project which would pander the majority of the concerned members (architects, customers, designers, contractors and so on) interests. Assessment technique is being considered and its features as well. The need to value the expenses associated not only with the construction period, but also with the exploitation period is explaned. A few examples are given about choosing a rational project considering not only the cost, but also some value factors that influence job quality or exploitation.

Abstract Polish energy security is based mainly on a coal. Such dependency will be still maintained for several years. It is therefore necessary to improve the economic situation of polish mining companies. The mining companies in Poland are operating under tremendous uncertainty of turbulent environment. The article presents used by the authors methods to facilitate the creation and selection of optimal production strategy. These are scenario planning, forecasting and linear programming, which allow the simulation of company operations in the future. The authors suggest the most successful and optimal forecasting models for the Polish mining industry, as well as factors affecting the demand for hard coal in Poland. The manuscript presents also possible to apply coal production strategies and the method of evaluation and selection of optimal strategy in the difficult conditions of Polish mining companies environment. This makes it possible to take a decision burdened with minor errors and less risk.

At present, the evaluation methodology on the design innovation of the stadia is not complete. The degree of innovation of the design scheme of the stadia still cannot be quantitatively estimated; this inability makes it difficult to guide the selection of a design scheme. To solve the problem of evaluation on the innovative design of the stadia, improve such design’s evaluation theory, and accurately direct the selection of the design scheme of the stadia, the Delphi method is used to select evaluation indexes. Moreover, analytic hierarchy process (AHP) is applied to determine the index weight in this study; based on this index weight, fuzzy comprehensive evaluation is used to establish the model of the design innovation evaluation of the stadia. The model involves the comprehensive and simple selection of indexes and the high reliability of weight selection; the model can quantitatively calculate the comprehensive index evaluation value of the design innovation of the stadia in a relatively accurate and rapid way. In this study, Hunan People’s Stadium is taken as the example for design innovation evaluation; the procedure of design innovation evaluation is introduced in detail. The design innovation evaluation value of the stadia is 2.977 through analysis; this value indicates an ordinary degree of innovation. The innovation evaluation value of the shape is 3.425; this value shows a relatively high degree of innovation. The innovation evaluation value of the structure is 2.47; this value represents a relatively low degree of innovation. The model in this study is an accurate and prompt model that can conduct a comprehensive evaluation on the design innovation of the stadia based on quantitative calculation. This model directly and comprehensively finds the advantages and disadvantages of a design scheme. Thus, it is quite suitable for the design innovation evaluation of the stadia.
