Vendor-managed inventory and bullwhip reduction in a two-level supply chain

Compares the bullwhip properties of a vendor managed inventory (VMI) supply chain with those of a traditional “serially-linked” supply chain. The emphasis of this investigation is the comparative impact the two structures have on the “bullwhip effect” generated. Particular attention is paid to the manufacturer’s production ordering activities as demonstrated using a simulation model b…

Ship safety in open ports

Ports and terminals open to prevailing winds can cause problems to moored ships with a high freeboard. Such ships, i.e. ship and berth mooring systems, have to deal with signifi cant aerodynamic loads.Th is paper addresses the theoretical approach of the infl uence of aerodynamic loads on a mooring system for ship and investigates whether windscreens can reduce aerodynamic loads on ships in ports

Deriving decision rules to locate export containers in container yards

A methodology is proposed to determine the storage location of an arriving export container considering its weight. We consider the con®guration of the container stack and the weight distribution of containers in the yard-bay. A dynamic programming model is formulated to determine the storage location to minimize the number of relocation movements expected for the loading operation. We also de…

This paper presents a dynamic programming algorithm to draw optimal intermodal freight routing with regard to international logistics of container cargo for export and import. This study looks into the characteristics of intermodal transport using multi-modes, and presents aWeighted Constrained Shortest Path Problem (WCSPP) model. This study draws Pareto optimal solutions that can simultaneousl…

Creating and assessing composite indicators: dynamic applications for the por…

Explaining the dispersion of economy-wide fluctuations, national and global, has been long sought by economists. Short- and long-lived versions of economic fluctuations are transmitted and reflected on the port and maritime industries. Through the creation and assessment of composite indicators, utilizing non-parametric spectral domain approaches, we are able to: (a) Extend the context inwhich …

A dynamic theory of leadership development

The paper offers a dynamic theory of leadership development.

Confidence and supply chain disruptions: Insights into managerial decision-ma…

This conceptual paper aims to shed light on the nature and determinants of managerial behaviour when affected by supply chain disruptions. It aims to argue that the managerial decision-making process is an important component in determining the eventual long-term impact of a supply chain disruption.

Supply chain management – back to the future?

Distribution arrangements are becoming increasingly complex and dynamic in business as well as in consumer markets. The purpose of the present paper is to explore and discuss the theoretical frameworks available to interpret these distribution arrangements, to uncover how they are interrelated and to suggest extensions.

What does “corporate governance” actually mean?

This paper aims to develop a framework of connotative meanings afforded to the term “corporate governance”.

A business model approach to supply chain management

This paper aims to extend the topics from a 2007 paper to stimulate debate on strategic issues vital for the long-term success of supply chains (SCs). The authors upgraded from SC process modelling towards SC business model management; from information to knowledge transfer and from the maturity of SC to dynamic capabilities. The paper attempts to identify and connect the elements of SC busines…

Development dynamics of the Portuguese range as a multi-port gateway system

The aimof this paper is to discuss the current status of port regionalization in the Portuguese range and to identify its possible developments, giving special consideration to cross-border issues. The ‘Portuguese range’ comprises a set of ports located in the west coast of the Iberian Peninsula, grouped in a multi-port gateway region, directly connected to one of the main European Union ra…

Assessment of empty container repositioning policies in maritime transport

Empty container repositioning is an important issue in the liner shipping industry. Generally stated, two groups of mathematical models have been proposed to tackle this issue. The first group aims to derive time-dependent origin-destination matrices that specify the number of empty containers to be repositioned at a decision epoch; the second group aims to develop effective statefeedback contr…

The purpose of this paper is to investigate the currency union (CU) effect on aggregate intra-trade in the Economic Community of West African States (ECOWAS) and on bilateral trade among individual countries using the gravity model.

System dynamics modeling for determining optimal ship sizes and types in coas…

The problem of determining the required ship investment for deployment is an ongoing problem faced by governments and ship operators. The nature of ship investment is capital-intensive and the return on investment is often take long time. This paper attempts to establish system dynamics modeling (SDM) to simulate and solve this problem in order to help ship operators make effective strategic de…

Marine port as one important aspect of transportation network set particularly in marine field, should be able to support transportation activities or human and good transport from a place (hinterland) to another (foreland). Selection of port that could give best service would be one of important decision issues which would be giving positive impact toward regional economy surrounding the port …

Taipower′s coal logistics system

Concerns the logistics system of the Taiwan power company, Taipower, and the problem it faces of coal allocation and fleet deployment of dedicated coal carriers. The coal allocation problem can be viewed as a multi‐index transportation problem requiring the formulation of a coal allocation model. Owing to the high uncertainty of shipping operations, formulates a dynamic fleet assignment mod…

Purchasing social responsibility and firm performance: The key mediating role…

This paper aims to examine how socially responsible supply management activities, a term labeled purchasing social responsibility (PSR) in the extant literature, affect a firm’s costs. There has been much debate, and mixed empirical findings, regarding whether socially responsible behavior on the part of companies improves or reduces firm performance.

Research into container reshuffling and stacking problems in container termin…

Container stacking and reshuffling are important issues in the management of operations in a container terminal. Minimizing the number of reshuffles can increase productivity of the yard cranes and the efficiency of the terminal. In this research, the authors improve the existing static reshuffling model, develop five effective heuristics, and analyze the performance of these algorithms. A disc…

Asian hub/feeder nets: the dynamics of restructuring

The emergence of hub/feeder networks in the Singapore-Japan corridor through the 1970s and 1980s reflected not only the rapid growth of containerized cargo in regional Southeast and East Asia but also the exceptional importance of Far East/transPacific and Far East/Europe mainline shipping services in structuring these networks. This paper argues that the mid-1990s is a defining moment in the r…

Dynamics of change in the port system of the western Mediterranean

The ports of Mediterranean basin have experienced significant growth in container traffic over the last decade. In the western Mediterranean two distinct types of port have emerged: the established ports of the northern part of the basin which serve a gateway function and a set of new ports in the south which act as transhipment hubs. In this paper we explore the dynamics of change and reveal h…
