Purpose - The purpose of this study is to find out how a company can do reasonable cost calculations in a simple way and establish profitability improvement strategies based on the results. Design/methodology/approach - In this study, a case that compounding company K applied TDABC was studied. A case study was conducted on the process of company K reviewing and applying TDABC and the process of implementing the cost calculation for each product by applying TDABC, and establishing a profitability improvement strategy for each product based on the results. Findings - Company K rearranged the production standard information of the compounding industry such as productivity and batch size of each product to apply TDABC. Cost calculation was performed for each product according to the revised production standard information. After the cost calculation for each product was carried out, Company K established a strategy to improve profitability of each product. The profitability improvement strategy was implemented in two ways: a cost reduction strategy and a product price increase strategy. As a result of the final strategy execution, the profitability of each product was improved. Research implications or Originality - This study found a reasonable costing standard in consideration of the specificity of the research target company, and applied it to cost calculation cost for each product.

As we move to competition, transmission cost become more and more important. At the wholesale competition market, the process of settlement must include the cost of transport. The aim of this paper is to calculate approximate transmission cost at each power sales district office using KEPCO data. We considered investment cost, transmission constraints and marginal losses as cost elements which must be taken into account in transmission cost calculation.

Objectives: The question of whether the level of fees paid to working environment measurement agencies is appropriate has long been a matter of concern to the government. In addition, measurement institutions express dissatisfaction with their level of compensation, which has a great influence on the evaluation of a subject's policy. This study is intended to find a way to appropriately calculate working environment measurement fees. Methods: We looked at the principle of fee determination as a basic theory of fee calculation used in fee calculation, the legal and academic aspects of the general method of fee calculation, and government cost calculation standards. Furthermore, we reviewed the research methods applied so far to derive a method of calculating fees appropriate for this environment. Results: The working environment measurement environment is different from other commission calculation environments. The other environment is to appropriately calculate the service price provided by a monopoly public enterprise, while the situation is to appropriately calculate the fees provided by competitive private enterprises. Therefore, the service delivery environment and the delivery entity are different. In this case, the appropriate method of calculating service fees would be competitive pricing. There have also been many problems under the method of calculation by service cost. Conclusions: First, the working environment measurement fee requires an accounting correction of endogenous variables. Second, the theory of calculating fees appropriate for this situation is appropriate for competitive pricing that applies to private competitors. Third, the government should make efforts to make the service supply market a fully competitive market while ensuring that the service fee level is determined at the marginal cost level. Fourth, economically, research on marginal cost levels is needed.

The current standard cost for recycling applied under the Extended Producer Responsibility(EPR) institution, is not coping with continuously increased number of obligatory subject items as well as a variety of variable cost changing factors regarding the recycling treatment cost caused by price fluctuation such as increased material and labor cost entirely across the society; changes in recycling treatment process following the developing technologies; and changes in the required work forces and equipments followed by the trends of automated facilities. Despite such various cost fluctuation factors, the current EPR is not coping with the trends, making the re-calculation process difficult, which causes differences between the real treatment cost for recycling. In this study, the analysis was made on main factors affecting on the related cost and the related price changing index was calculated, by conducting the influence evaluation on the standard cost factors of the current standard cost for recycling. Through theses results, more objective standard will be set for the re-calculation of standard cost for recycling to greatly contribute to setting up the midterm and long-term strategies in the future towards efficient institution.

Estimating the reasonable construction-cost according to the construction phase in public construction is an important element for securing and executing a national budget efficiently. As a general rule, the predetermined cost of construction is estimated at the end of the design of the target structure. Therefore, it seems to be a considerably difficult problem to estimate the approximate cost of construction, only with its basic information of the bridge in the design planning phase and the early design stage where we can not have specific detailed-section of the target structure. In this paper, we present the calculation of construction-cost in the planning phase based on the analysis of factors affecting the cost of construction conducted in the previous study. Beside, to estimate the cost of construction in early design phase, we would like to present the calculation of construction-cost in the early design phase by executing the analysis of data collected from 61 steel box bridges. It was found from the result of study that the estimated cost of construction gained by the calculation of construction-cost in this paper reduces the error between the real cost of construction and that by the existing method of using.

In the Construction Technology Promotion Act (CTPA) of the Republic of Korea, safety management cost is enforced as a statutory cost that must be included in the budget of construction projects. However, the construction of underground electric power transmission facilities (UEPTFs) is not included in the category of construction works defined in the CTPA. Consequently, the statutory safety management cost does not apply to the construction of UEPTFs. To overcome this limitation, the clients of UEPTF construction projects generally provide internal guidelines enabling the addition of the safety management cost in the project budget. Nevertheless, even after the execution of the internal guidelines, some important cost items are omitted from the budget owing to the incompleteness of the guidelines. In this context, this paper proposes a complete set of accounting items and their calculation methods for appropriate budgeting of the safety management cost of UEPTF construction projects. To this end, the current budgeting method of the safety management cost of UEPTF construction projects is analyzed, and a questionnaire study is performed to confirm the necessary cost items and their appropriate calculation methods. Based on the results of the questionnaire study, a set of accounting items and their calculation criteria for the budgeting of the safety management cost of UEPTF construction projects are proposed.

공기연장에 따른 간접비 산정에 관한 연구가 최근 정량적인 부분에 집중되어 제시되고 있으며, 최근 제도개선에 관한 연구가 계속적으로 이루어지고 있다. 국내 공공 공사의 경우 발주자가 국가인 경우에는 국가계약법을, 지방자치단체인 경우에는 지방계약법을 적용받게 되는데 이러한 산정기준의 문제점에 대해 명확하게 개선방안의 요구가 있음에도 개선방안이 제시되고 있지 않아 개별 문제점에 대한 면밀한 연구가 필요한 실정이다. 본 연구는 이러한 배경에서 '국가계약법'에 따른 산정기준과 '지방계약법'에 따른 산정기준의 각 산정결과를 비교하고, 문제점을 고찰 후 현장사례를 분석하여 적정한 기준을 제시하였다. 각 규정을 고찰한 결과 기타경비 산정방식이 다르게 규정되어 있었으며 이에 따라 실제 비용이 적게는 12.37%부터 24.95%까지 차이가 발생하고 있다는 결과를 얻을 수 있었다. 이러한 문제점은 실비가 아닌 계약당시 요율을 그대로 기타경비요율로 적용하는 국가계약법에 따른산정방식의 문제점에 따른 것이며, 이에 따라 실제 비용보다 적은 공기연장 비용이 산정되는 것으로 나타났다. 이에 본 연구는 현장자료를 기반으로 적정한 기타경비 산정요율을 총공사비 대비 1일당 기타경비 요율과 간접비 대비 요율방식으로 제시하였다.

The generator cost function is one of the basic data for the generation scheduling. Generally the cost functions are obtained form design calculations or from heat rate tests. The real operating condition may be different from the condition of design or the tests. Some of the conditions may not be tested during the periodical maintenance. In order to improve the calculation of the generator cost function, this paper presents a new calculation method of the generator cost functions using the utilization factors of generators and the mixed fuel burning ratio of the generators.
