ItemQuantity and Location Decision of Fresh Food Distribution Centers for a Supermarket Chain under Carbon Policies( 2017-01-04)Supermarket chains handle frequent deliveries of fresh food to the stores, which have led to the non-ignorable high transportation cost. Then a question arises that is it possible to reduce cost by establishing more refrigerated distribution centers (DC)? To answer this question, on basis of data from a large supermarket chain in China, we analyze the decision making process to construct new sub DCs. A balance of the DC cost and the transportation cost is achieved to gain the optimal number and location of sub DCs. We also extend the model to situations with carbon policies (carbon tax policy and carbon cap-and-trade policy). The locations of sub DCs remain the same under carbon policies. Furthermore, a carbon tax policy does not change the number of sub DCs and only causes an increase in the total cost. Under a carbon cap-and-trade policy the optimal decision of the DC number is dependent on the carbon selling rule.
ItemBig Data and its Applications in Supply Chain Management: Findings from a Delphi Study( 2017-01-04)Big data and its applications have increasingly received interest by both scholars and practitioners. However, there is still missing evidence regarding how big data is understood as well as its applications in supply chain management (SCM). Empirical contributions are especially limited. This study seeks to address this gap through an explorative Delphi study to understand the terminology of big data and its application in the SCM processes of sourcing, manufacturing, service, logistics, planning, and return. The findings reveal that big data is mostly concerned with data collection and logistics, service, and planning processes are the most applicable processes for deploying big data analytics in SCM. Furthermore, a range of applications have been identified and ranked within each process.
ItemAn Analysis of Digital Transformation in the History and Future of Modern Ports( 2017-01-04)Digital transformation is of utmost importance in the business world with major impacts on any of its sectors. Here we consider ports and logistics within maritime shipping to exemplify those developments. That is, as actors in world-wide supply chains, seaports are particularly affected by technological change. Due to the high requirements in the logistics sector, e.g., regarding costs, efficiency, security, and sustainability, digital innovation is essential to stay competitive. Past developments show how digital innovation can shape the modernization of ports. In order to understand future challenges in this area, it is inevitable to review the outcomes of past developments and their impact on port operations. In this paper, we provide an extensive analysis of digital transformations in seaports. We identify three generations and analyze the stages of respective digital transformations using a well-known model from literature. Based on the observations, we identify important aspects and challenges.
