In this article, the efficiency loss of a beer filling line is investigated and modeled to improve its system performance in terms of overall equipment effectiveness and productivity. First, research is aimed at problems related to beer filling line resulting from poor production management where utilization and productivity of filling machines are low. This article derives the overall equipment effectiveness of filling machines and overall throughput effectiveness of the filling line, with the overall throughput effectiveness of general system (OTE(S)) obtained based on these measurements. Based on these metrics, the efficiency evaluation system is established. Next, according to the efficiency evaluation indexes, overall equipment effectiveness, and OTE(S), the overall efficiency of filling machines and filling line are calculated, respectively. From the results, the stenciling machine has the lowest efficiency. However, considering overall throughput effectiveness indexes and production capacity, unit 3 is the bottleneck and limits the entire productivity. Finally, efficiency loss is analyzed based on the overall equipment effectiveness and OTE(S) calculation results. Using a fishbone diagram for analysis, the cause of equipment loss is summarized and countermeasures are offered. Theory of constraint is used to analyze the efficiency loss of the filling line and give suggestions for improvement. This research can help beer enterprises achieve continuous improvement of equipment efficiency and production capacity.

Critical Literature

Containerization was one of the catalysts of the globalization processes that took place in the 20th century. Nowadays container shipping is one of the main transport modes in the global economy. The ability to connect distant production centres with consumption centres largely influenced the acceleration of the global trade. Due to the globalization and characteristics of the global trade it is almost impossible to perceive global supply chains without maritime transport. Although the efficiency of the supply chain is a crucial factor of the economic perspective of supply chain management, not much space is devoted to that issue in the literature. The main purpose of this paper is to design and develop a model of an economic efficiency evaluation system of maritime container supply chains. Some general research methods, such as a critical literature review and methods of logical reasoning were used to achieve this goal. Additionally some economic modelling methods were adapted. Thepresented model isdeveloping the current state-of-the-art knowledge in the field of economic efficiency evaluation of supply chains. Unfortunately this model could not be confronted with real business data due to research limitations.

Energy Efficiency Evaluation

Thermal power industry in China is facing energyshortage , but now there is a lack of a comprehensive energy efficiency evaluation system to promote the energy efficiency ,The energy efficiency evaluation for steam turbine and auxiliary system fills this gap. On account of the fuzziness and randomness of the evaluation process, we propose the AHM-F combination evaluation method.It not only evaluted the energy efficiency level of the steam turbine and auxiliary system,but also point out the direction for further improving of energy efficiency level. The scientificalness and effectiveness of the proposed method is verfied by the example analysis of the 600MW unit in a power plant.

In order to sustainably and reasonably evaluate the characteristics and efficiency of regional atmospheric environment, this paper calculated the atmospheric environmental efficiency and regional differences, which is based on the non-radial directional distance function DEA model, among 11 cities in Zhejiang Province from 2006 to 2016 in both static and dynamic dimensions. Compared with existing researches, the atmospheric environmental efficiency evaluation system constructed in this paper not only considered the development of regional economy, but also focused on the air quality output so as to constrain the emission of atmospheric pollutants. The results showed that the average value of the static efficiency of atmospheric environment in Zhejiang was 0.6824 over the past ten years, and there was still about 32 percentage difference from the production frontier. The room for improvement in pollution reduction and control was still huge. The pure technical efficiency was the main factor to impede the improvement of atmospheric environment’s static efficiency in Zhejiang. Meanwhile the dynamic efficiency of atmospheric environment in Zhejiang reached an average annual rate of 7.60%, with a cumulative increase of 93.28%. As well, there were significant urban differences in the growth rate, of which Hangzhou was the fastest, followed by Ningbo and Jiaxing. The improvement of atmospheric environmental efficiency was mainly driven by technological advancement and scale efficiency expansion. The distribution of 11 cities in the four high and low environmental efficiency matrices was relatively uniform, and there was no “Matthew Effect” of H/H or L/L polarization. In the future, Zhejiang needs to formulate corresponding measures to control the atmospheric pollution by fully considering the actual conditions at different cities, and effectively strengthen the environmental management exchanges and collaboration within the province to enhance the overall atmospheric environment efficiency.
