The purpose of this paper is to discuss the methodology of optimizing delivery route scheduling using a capacity integer linear programming problem model developed to a previous case study. The methodology suggests a two-stage decision: the first, automatic, where the manager will obtain guidance generated by the solution of the linear programming model, later they could use post-optimization techniques to fine tune to the best operational solution. This study has the goal to reduce the size of service companies' ground transportation fleets, aiming not only to reduce costs and increase competitive advantages but also to lower levels of air pollution and its consequences, traffic and, therefore, the levels of carbon dioxide, allowing for a reduction in envir onmental disasters.

Recently much research efforts have focused on how to manage carbon emissions in logistics operations. This paper formulates a model to determine an optimal shipment size with aims to minimize the total cost consisting not only of inventory and transportation costs but also cost for carbon emissions. Unlike the literature assuming carbon emission factors as a given condition, we consider the emission factors as decision variables. It is allowed to make an investment in improving carbon emission factors. The optimal investment decision is shown to be of a threshold type with respect to unit investment costs. Moreover, the findings in this work provide insights on the various elements of the investment decision and their impacts.

Purpose - The principle aim of this study is to further investigate the relationship between market diversity and export performance. We examine the benefits and costs of geographic market diversity regarding the number of countries exported to by firms on their export performance. Based on the financial risk reduction model and the entry costs model, we propose a way to incorporate the costs and benefits aspects of market diversity. Design/methodology - To empirically investigate our research question, the curvilinear relationship between market diversity and export performance, we built a secondary panel data set between 2015 and 2019, containing 17,863 observations of Korean exporting companies. A generalized least squares panel estimator with fixed effects was employed to test the hypothesis, and the statistical package, Stata 14, was used. Findings - Our main findings are as follows: As market diversity increases, export performance increases because exporters can diversify and reduce financial risks in export markets. However, the relationship between the two does not grow. As it peaks, the entry costs increase due to the high market diversity, thereby outweighing the benefits, leading, eventually to decrease in the export performance. Consequently, there is an inverted U-shaped relationship between market diversity and export performance. Originality/value - In the export and trade literature, the impact of market diversity on export performance has not been addressed yet, despite the importance of this subject. Many scholars have assumed a positive linear relationship between the two, considering only the decrease in market risks as the number of overseas markets increases, without examining the increase in the entry and management costs. Therefore, our study contributes by providing a new perspective for analyzing the characteristics and outcomes of market diversity.

Purpose - This is a case study aimed at finding a solution for improving the pallet loading efficiency in the process of delivering products through a transshipment using the T-11 and T-12 pallet systems. The study proposes a solution by demonstrating the case of a certain manufacturer A, who aims to reduce the logistics cost by using packaging sizes that are commonly applicable and can improve the compatibility between the T-11 pallet system, designated as the standard pallet in Korea, and the T-12 pallet system, which is commonly used in other foreign countries. The use of common sizes increases compatibility among the two systems and reduces both logistics and environmental costs. Thus, this case study calculates the quantitative benefits of applying common packaging sizes to improve the compatibility between the T-11 and T-12 pallet systems. These systems are considered to be the most important and widely used transportation systems in the global logistics industry. Research design, data, and methodology - This study examined manufacturer A's representative product and delivery system and assessed how manufacturer A was affected by the use of incompatible packaging sizes in the T-11 (1100 mm×1100 mm) and T-12 (1200mm×1000 mm) pallet systems, which were specified in the KS T 1002 standard. In addition, this study analyzed the impact of these packaging sizes on A's logistics cost. The TOPS program (Total Packaging System) was used to simulate pallet loading efficiency,and the main parameter studied was volume, as calculated from length, width, and height. Results - When the sizes of secondary packaging were not compatible across the T-11 and T-12 pallet systems, a reduction in loading efficiency was observed, leading to an increase in logistics cost during transshipment. Such low loading efficiencies led to a further loss of efficiency in transportation, storage and unloading. This may have a possible environmental impact with high social expenses, such as increased CO₂ emissions. Hence, this study proposed that the KS T 1002 standard be amended to include 21 packaging sizes, including 7 sizes of the 600 mm×500 mm category, which are compatible with both the T-11 and T-12 pallet systems. Conclusions - This study found that the 69 standard sizes under the T-11 pallet system and the 40 standard sizes under the T-12 system in the KS T 1002 standard can be simplified and reduced to 21 mutually compatible packaging sizes, enabling logistics standardization and reducing national-level logistics costs. If the government pays attention to this study and considers the standardization of common sizes for the T-11 and T-12 pallet systems and amends the KS T 1002 standard, this study will deliver practical value to the global logistics industry, apart from being of academic significance.

기업의 공급망 관리와 소비스 만족도 향상, 효율적 물류관리 차원에서의 기업 물류거점의 규모 및 위치 결정 등의 전략을 수립하는 것은 기업의 장기적인 비전과 직결됨과 동시에 물류 최종목표인 고객만족을 극대화시키는 기업전략과 일치하는 매우 중요한 의사결정이다. 따라서 본 연구는 국내 기업을 대상으로 실제 기존 물류거점 및 물류비용을 분석하고 기존 물류거점을 재조정, 재배치하여 물류비 절감 및 물류 효율성을 제고함으로 향후 타 기업의 물류거점 구축 및 재배치에 유익한 시사점을 제공하고자 한다.

The fundamental objects of the Korean Grand Canal (KGC) Project are the rehabilitation(or restoration) of river corridor ecology, improvement of river water quality, reduction of flood damages, countermeasure of the huge rise in energy price and the high discharge of $CO_2$ due to the vast use of energy for highway logistics. The other important objects, like an increase of water in the river channel, are to provide people with the pleasure of seeing the water and intimacy (touchiness) with it, an increase of flood controllability, effects of dilution of river pollutants, dredging out sedimentary pollutant from the river bottom, the function of infrastructure to pare down the logistics (distribution) costs, and the opportunity to expand tourism. These kinds of fundamental concepts must be evaluated as future values in Korea and elsewhere.

본 논문의 주된 연구목적은 기존연구에서 거의 고려되지 않았던 산업재 구매시장에서의 물류환경특성과 물류자원역량이 관계규범과 물류서비스를 통하여 물류성과에 미치는 영향을 분석하는 것이다. 제안한 연구가설들을 검정하기 위하여 H중공업 및 HSD엔진의 구매부, 자재관리부, 수출입관리부, 외주관리부, 수입검사부 등의 물류관련부서에 종사하는 핵심 응답자로부터 272부의 설문지를 수집하여 자료분석에 이용하였다. 구조방정식 모형 분석을 통해 알아낸 분석 결과를 연구주제별로 살펴보면 다음과 같다. 첫째, 산업재구매에서 환경의 역동성, 이질성 등의 물류환경 불확실성은 기대와는 다르게 가용성, 적시성 등의 물류서비스와 정보교환, 유연성 등의 관계규범에 유의한 영향을 미치지 않는 것으로 나타났다. 둘째, 물류자원역량은 구성요인의 특성에 따라 효과가 다르게 나타났다. LIS 등의 물류정보화는 직접적으로 물류서비스에 영향을 미치지 못하고 관계규범을 통하여 간접적으로 물류서비스에 유의한 영향을 주었고 반면에 물류 거래특유투자, 수송서비스 능력 등의 물류자원은 관계규범에는 영향을 주지 못하고 직접적으로 물류서비스에 유의한 영향을 미치었다. 셋째, 거래당사자간의 합의된 관계규범은 물류서비스를 유의하게 높이는 것으로 나타났으나 물류비용절감, 배송의 질 등의 물류성과의 제고에는 별다른 효과를 나타내지 못하였다. 넷째, 많은 선행연구들의 결과와 일치하게 장기적 관계를 기반으로 하는 산업재구매자와 자재공급업자의 거래에서 관계규범을 바탕으로 한 우수한 물류서비스는 리드타임 일관성, 배송품질 향상 등의 물류성과에 유의한 영향을 주었다. 마지막으로, 본 논문에서 밝혀진 물류환경, 물류정보화, 물류자원, 관계규범, 물류서비스 및 물류성과 간의 연관관계에 대한 분석결과들은 산업재 구매자들에게 이론에 근거한 전략적 물류관리 실천방안으로 활용될 수 있을 것이다.
