자동차 부품업체의 TDABC 적용사례 연구

Abstract

[Purpose]If activity－based cost calculation is a cost calculation method that can be applied to blue－chip companies with advanced ERP systems, TDABC is a relatively easy and simple cost calculation method that can be applied even to a small number of SMEs. This study attempted to confirm the usefulness of TDABC by analyzing the difference between the time－active cost calculation (TDABC) method and the existing cost calculation method based on the cost data of S, a case company in the automobile parts manufacturing industry. [Methodology]Unlike the traditional cost calculation of case company S, the process time was calculated by applying the TDABC system by the time equation. Through this, not only the actual operation level was divided into usage time and idle time, but also cost reduction and profit rate improvement measures were prepared by dividing the cost into usage cost and idle cost. [Findings]Summarizing the analysis results of this study, for case companies, the operating margin based on traditional cost calculations was 2.8%, whereas the TDABC system was analyzed as 6.7% of the operating margin for the cost of use, excluding idle costs. In other words, the cost of the TDABC system is a way to increase the operating margin along with the reduction of the idle cost sector. Therefore, it was confirmed that the introduction of the TDABC system for case companies can increase the efficiency of cost management. [implications]Unlike previous studies that calculated the cost incentive rate in the dedicated facility system, this study is significant in that it analyzed the usefulness of TDABC by applying time－driven cost calculation in the multi－species production system because case company S is building a system of general－purpose facilities.
