The purpose of this paper is to reveal two problems in the existing inventory systems in retail market, and to suggest a Two-Bin System under Automatic Ordering System considering only base-stock. Large retailers already have a sophisticated inventory system based on an automatic ordering principle. However, why does the out-of-stock (OOS) happen in large discount stores in spite of having a good inventory system? This paper suggests two systems after finding the root causes concerning the previous question. For evaluating the performance of each system, the random 200 data set in each sample group was generated from MINITAB 16 and obeyed the Poisson distribution. The existing inventory system in retail market cannot help generating OOS due to indwelling contradiction in itself. The reasons are the ordering deadline and the relationship between ordering quantity and base stock. This paper also demonstrates that these previous studies on inventory fall into the closed loop. Also the paper shows that the performance of the replenishment policy was better than traditional methods dealing with ordering quantity and base stock.

This review paper aims at providing a systematic analysis of articles published in various journals and related to the uses and business applications of big data. The goal is to provide a holistic picture of the place of big data in the tourism industry. The reviewed articles have been selected for the period 2013-2020 and have been classified into 8 broad categories namely business strategy and firm performance; banking and finance; healthcare; hospitality; networks and telecommunications; urbanism and infrastructures; law and legal regulations; and government. While the categories are reflective of components of tourism industries and infrastructures, the meta-analysis is organized around 3 broad themes: preferred research contexts, conceptual developments, and methods used to research big data business applications. Main findings revealed that firm performance and healthcare remain popular contexts of research in the big data realm, but also demonstrated a prominence of qualitative methods over mixed and quantitative methods for the period 2013-2020. Scholars have also investigated topics involving the notions of competitive advantage, supply chain management, smart cities, but also ethics and privacy issues as related to the use of big data.

본 연구는 중소 제조기업을 중심으로 SCM의 선행요인이 정보공유와 협력에 미치는 영향과 정보공유가 협력에 미치는 영향을 파악하고, 궁극적으로는 SCM의 주요 활동인 정보공유와 협력이 기업의 성과에 미치는 영향을 BSC의 네 가지 관점으로 구분하여 연구하였다. 연구 결과 선행요인인 몰입과 문화의 유사성은 정보공유에 유의한 영향을 미치고 상호신뢰와 기업규모는 협력활동에 유의한 영향을 미치는 것으로 나타났다. 활동간의 관계에서도 정보공유는 협력에 유의적인 것으로 나타났다. SCM 활동과 성과 간의 관계에서는 협력은 4가지의 균형성과 모두에 유의적이었지만 정보공유는 그러하지 못하였다. 그러나 정보가공유가 협력에 유의적이고 협력이 균형성과에 유의적인 영향을 미침에 따라 정보공유 또한 4가지의 균형성과에 간접적인 영향을 미치는 것으로 판명되었다. 따라서 본 연구의 결론은 SCM의 주요 활동인 정보공유와 협력이 선행요인의 영향을 받아서 기업의 균형성과 즉, 고객시각의 성과, 내부 프로세스 시각의 성과, 학습 및 성장시각의 성과, 재무적 시각의 성과에 직접 혹은 간접적으로 영향을 미친다는 사실을 확인할 수 있었다.

Research indicates that good front-end planning (FEP) results in the achievement of higher levels of project performance. By facilitating collaboration among stakeholders in diverse locations with the use of workflow-enabled processes, such pressures can be reduced, and the overall process and results of FEP can be improved. With these goals, a front-end planning tool (FEPT) has been developed as support for owners and major contractors who are engaged in front-end planning. This paper presents the new FEPT and describes how it has been used for construction megaprojects in the nuclear power, oil and gas, and mining industries. The paper begins with the definitions related to and an explanation of the general process for implementing and applying the FEPT and then describes and analyzes how the FEPT was applied in case study projects in order to test its validity. The results indicate that the FEPT increases the efficiency and effectiveness of front-end planning for the megaprojects studied and that it has the potential to produce similar results for other megaprojects.

This study aims to establish the relationship between the Green Marketing Orientation (GMO) variables and the performance of Green Small and Medium Enterprises (GSMEs) across the building and energy sectors in Malaysia, using customer satisfaction as a means of performance measurement. The GMO variables examined include Greening the Process (GTP), Green Supply Chain Management (GSCM), Green Strategic Policy Initiatives (GSPI), Proactive Energy Conservation (PEC) and Green Promotion (GP). The items used to measure these variables were extracted from literature and adapted to the context of the variables based on feedback from Focus Group Discussions and Expert Opinion sessions. This study employs a survey sample of 300 respondents but only 238 completed questionnaires were returned. The results reveal that GTP, GSCM and PEC have a positive impact on Customer Satisfaction but not GSPI and GP. The findings suggest that owners or managers of GSMEs should focus on maintaining and improving GTP, GSCM and PEC in order to create greater satisfaction among their customers. The significance of this study is that it enables the creation of a framework that enables GSMEs to design a pathway towards achieving a cleaner production of goods and services in line with United Nations Sustainable Development Goals.

본 연구는 국내 제조업체를 대상으로 하여, 공급업체 선택기준 요인으로서 원가 요인과 유연성 요인의 적합성을 검증하고, 그들이 공급사슬 성과에 유의한 영향을 미치는가를 확인하는 것을 첫 번째 목표로 한다. 나아가 IT 중 POS, EDI, ERP의 기술들이 그 과정에서 조정적(moderate) 효과를 나타내는가를 실증적으로 검증하고자 한다. 전국에 소재한 제조업체를 표본조사하고 조정적 회귀분석의 방법에 의하여 검증한 결과, 유연성 요인은 공급사슬 성과에 유의한 영향을 미치고 있으며, IT 기술들의 조정효과는 매우 낮은 것으로 나타났다. 이러한 결과는 IT 투자의 '생산성 역설'과 관련이 있는 것으로 볼 수 있다.

The traveling purchaser problem(TPP) is a generalization of the well-known traveling salesman problem(TSP), which has many real-world applications such as purchasing the required raw materials for the manufacturing factories and the scheduling of a set of jobs over some machines, and many others. TPP also could be extended to the vehicle routing problem(VRP) by incorporating additional constraints such as multi-purchaser, capacity, distance and time restrictions. In the last decade, TPP has received some attention of the researchers in the operational research area. However it has not received the equivalent interest as much as TSP and VRP. Therefore, there does not exist a review of the TPP. The purpose of this paper is to review the TPP and to describe solution procedures proposed for this problem. We also introduce the ILP formulation for the multiple TPP(mTPP) which is generalized type of TPP. We compare the system performance according to change from TPP to mTPP.

RFID technologies have attracted a lot of attention in recent years because of their cost/time-effectiveness in large-scale logistics, supply chain management (SCM) and other various potential applications. One of the most important issues of the RFID-based systems is how quickly tags can be identified. Tag collision arbitration plays a more critical role in determining the system performance especially for passive tag-based ones where tag collisions are dealt with rather than prevented. We present a novel tag collision arbitration protocol called Optimum Frame-Slotted Aloha (OFSA). The protocol has been designed to achieve time-optimal efficiency in tag identification through an analytic study of tag identification delay and tag number estimation. Results from our analysis and extensive simulations demonstrate that OFSA outperforms other collision arbitration protocols. Also, unlike most prior anti-collision protocols, it does not require any modification to the current standards and architectures facilitating the rollout of RFID systems.
