Planning inventories for emergency supplies such as bottled water, non-perishable foods, batteries, and flashlights can be challenging for retailers situated within the projected path of a severe storm. The retailer’s inventory decisions are complicated by the inherent volatility of storm forecasts and the corresponding demand predictions. The purpose of this paper is to explore both proactiv…
Following a general discussion on port pricing policies and structures the author explores the argument that price in itself provides an inadequate focus of needs and preferences of port users, especially users of container terminals, and suggests a system of input pricing related to the sale of terminal capability on a time basis.
Polarica is a company in northern Europe buying, refining and selling wild berries and other specialty foods. During the last couple of years the volume of wild berries, mostly blueberries, has increased a lot. This expansion forces Polarica to consider investments in freezing-in capacity and cold-storage capacity. A simple heuristic model was constructed, from which it was concluded that addit…

The Law of Industrial Dynamics ensures that if a production control system can amplify then it will surely find a way of doing so despite the best efforts of production schedulers to take corrective action. In fact, practical studies show that such human intervention frequently aggravates the situation with both stock levels and order rates fluctuating alarmingly. The solution is to design an e…
The purpose of this paper is to describe the challenge of managing logistics at corporate level in construction industry; and to present and evaluate vendor-managed-inventory (VMI) as a potential solution for small item logistics.
Control of logistics operations at container terminals is an extremely complex task, especially if automated guided vehicles (AGVs) are employed. In AGV dispatching, the stochastic nature of the handling systems must be taken into account. For instance, handling times of quay and stacking cranes as well as release times of transportation orders are not exactly known in advance. We present a sim…

When senior executives, middle managers and staff employees of a global shipping company and maritime industry group were questioned about corporate social responsibility (CSR), the majority of them had never heard of the term. Neither had they come across the term 3BL (triple bottom line) which refers to how a business carries out a comprehensive assessment of environmental and social performa…
We show how a seaport container terminal’s long-run average quay crane rate depends on the system that automatically assigns yard trucks to container transportation jobs in the terminal in real time. Several real-time, dual-load yard truck control systems are proposed and evaluated by a fully-integrated, discrete event simulation model of a vessel-to-vessel transshipment terminal. The model i…
The purpose of this paper is to systematically describe the key practical contributions of the theory of constraints (TOC) to outbound (distribution) logistics.
Some managers may assume that improvements in service can only be achieved by an increase in stock investment and that any stock reduction will reduce service efficiency. However, it is possible to combine a reduction in stock with an overall increase in effectiveness. Unisys found that this “win‐win” option is a viable alternative when it carried out a review of its customer service bu…

This research applies the construct of bullwhip effect in a non-traditional context. It is explored in intra-organisational echelons. It is argued that the bullwhip effect in a company’s inventory management of inbound and outbound logistics flows depends in part upon the gap between the degree of speculation and postponement of business activities. It is also argued that the bullwhip effect …
Modern manufacturing systems enable manufacturing management to plan, control and record manufacturing activities. However, manufacturers have been found to adopt practices and incur overheads to deride the benefits arising in other operational areas of their activities from the implementation of traditional systems. Current manufacturing practices are burdened by the legacy of these traditiona…
