  • Korea Water Resources Corporation (KOWACO) annually supplies about 2 billion Kwh and 7.3 billion $m^3$ with its 10 multi purpose dams and 20 water supply offices. For the proper control and management of the above utilities, sequential control equipment and SCADA/DCS have been operated and maintained. In this paper, 8 control system evaluations for hydropower dam, water supply, electric power and subway projects during 1984-1997 were reviewed and analyzed. The systematic evaluation method has been established in the points of the purpose, method, procedure, evaluation team, evaluation criteria, total evaluation table and the contents of final recommendation report. With keeping in mind the essential points, it is expected for the more effective and fair evaluation of bids.

  • PURPOSES : This study evaluates the efficiency of snow removal operation resources using data envelopment analysis (DEA). The results of this study can help decision-making strategies, especially for resource allocation for snow removal works on national highways. METHODS : First, regional road management offices (DMUs) for efficiency evaluation were set up, and a database (for years 2012-2016) for analysis was formed. Second, DEA was carried out by selecting input and output variables based on the constructed database. Lastly, based on the results of the DEA, the efficiency of each regional road management office was evaluated. In addition, the potential for future improvement was determined. RESULTS : The results showed that there was a large variation in efficiency of snow removal operation resources by regional offices. CONCLUSIONS : The results of this study imply that the evaluation of efficiency for snow removal operation resources is important when decisions related to snow-removal strategies are made by road management offices.
