국가 전체의 지속가능한 교통체계 확립을 위한 연계교통체계의 구축이 중요한 교통정책으로 대두되고 있고 철도 및 대중교통은 통행의 완결성 부족으로 인해 수단간 연계성을 고려하는 것이 필수적이라 할 수 있다. 특히, 고속철도는 우리나라 교통체계의 획기적 변화를 가져왔고 고속철도역은 다양한 수단이 연계되어야 하는 중요한 교통 결절점으로 수단간 연계교통망 차원에서 분석이 필요하다. 이에 본 연구는 고속철도역의 연계교통망 차원에서 고속철도와 연계교통수단의 연계기능을 객관적이고 정량적으로 분석하기 위한 새로운 연계성 분석 기법을 제시하였다. 서울역, 부산역, 울산역, 신경주역을 공간적 범위로 설정하였고 고속철도 역사내의 내부환승 시설을 제외한 고속철도역과 영향권내 기 종점간을 연결하는 연계교통수단의 세부 연계기능 지표를 조사 분석하였다. 구축된 자료를 이용하여 구조방정식 모형을 적용한 연계성 분석 기법을 제시하고 연계성 지표를 개발하였다.

This paper proposes a strategic model of linkage between productivity metrics and financial accounting metrics to properly evaluate the financial effect of TPM activities and the business performance. This linkage strategy provides a connection tool for clear communication between factory-level and headquarters that the metrics proposed by this paper ultimately improves a quality of support from the management by receiving the factors required for productivity activities in the practical field. This factor includes such as equipment, raw materials and labors. Here, we propose that chain reaction models using break down structure of productivity metrics and financial metrics enhance the knowledge sharing of KPI (Key Performance Indicator) which generally tend to create oversimplified communication between management in headquarters and employees in the practical fields. The productivity metrics include OEE(Overall Equipment Effectiveness) of TPM (Total Productive Maintenance), OLE (Overall Labor Effectiveness) of PAC(Performance and Analysis and Control) activities, and OYE (Overall Yield Effectiveness) of TMM(Total Material Management) activities. The financial accounting metrics include ROE(Return on Equity), ROA(Return on Asset), and AVR(Added-Value Rate). The suggested chain reaction model selects the financial metrics as initial stage and branch down until final stage of productivity metrics. When demand exceeds supply, an ideal speed rate, the lean OEE strategy can be initially applied to reduce the gap between the demand and supply, then apply variable costing to estimate correct amount of operating profit. In addition, the paper presents a new type of model for linkage between financial accounting metrics including CAPEX(Capital Expenditure), OPEX(Operating Expenditure), EVA(Economic Added Value), DCL(Degree of Combined Leverage), and TPM productivity activities including AM(Autonomous Maintenance), PM(Preventive Maintenance), MP(Maintenance Prevention) and QM(Quality Maintenance). In order to support the evidence of proposed linkage strategy, a case analysis on 52 projects from national TPM contest from 2011 to 2012 is analyzed. The case presents the classification of CAPEX and OPEX activities from TPM, and proposes the correct implementation of financial effect for TPM projects.
