The storage constrained, inbound inventory routing problem

This paper aims to describe the storage constrained, inbound inventory routeing problem and presents bounds and heuristics for solutions to this problem. It also seeks to analyze various characteristics of this problem by comparing the solutions generated by the two proposed heuristics with each other and with the lower bound solutions.

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…

Integration of demand forecasts in ABC-XYZ analysis: practical investigation …

Item classification based on ABC-XYZ analysis is of high importance for strategic supply and inventory control. It is common to perform the analysis with past consumption data. In this context, the purpose of this study is to test the hypothesis that an integration of demand forecasts can improve the performance of item classification, in particular the performance of ABC-XYZ analysis

Pre-storm emergency supplies inventory planning

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…

Polarica's wild berries: an example of a required storage capacity calculatio…

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…

Dynamic simulation modelling for lean logistics

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…

Vendor-managed-inventory (VMI) in construction

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.

The Unisys parts supply chain - the win-win option

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…

The bullwhip effect in intra-organisational echelons

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 …

Taking the manufacturing order out of manufacturing: how modern systems enabl…

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…

Optimization model for transportation planning with demand uncertainties

The purpose of this paper is to investigate the total cost function of an inventory system with a reorder point/order quantity policy where the lead time is controllable based on the cost paid by the buyer for the service.

Moving beyond trade-OFFS

Logisticians are trained to identify trade‐offs and to devise compromising solutions which produce the lowest total costs. For example, the economic batch size is a compromise between setup costs and inventory carrying costs. Presents a problem‐analysis technique which helps the analyst to eliminate the problem so that no compromise is necessary. For example, instead of balancing inventor…

Monitoring information and materials to enhance logistics performance

The need to make forecasts is commonplace in industry. The accuracy (and hence, usefulness) of forecasts varies from one sector to another, but is rarely high. Describes an approach to the monitoring of forecasts which aims to detect significant inaccuracy and to quantify the correction(s) that need to be made, based on well‐established methods of SPC, and so it also allows any changes in the…

Linking warehouse complexity to warehouse planning and control structure: An …

Warehousing is becoming more and more a critical activity in the supply chain to outperform competitors on customer service, lead times, and costs. However, if warehousing is to be a source of competitive advantage, then the implementation of a warehouse management information system (WMS) is a necessary condition to achieve efficiently the high performance of warehousing operations required …

Joint inventory and constant price decisions for a continuous review system

The purpose of this paper is to study joint inventory and pricing strategy for a continuous inventory review system. While dynamic pricing decisions are often studied in the literature along with inventory management, the authors’ aim in this study is to obtain a single long-run optimal price; also to gain insight about how to obtain the optimal price and inventory control variables simultane…

Inventory control in environments with short lead times

The objective of this study is to revise and enhance existing inventory control models in a way that allows them to be used more efficiently in environments with short lead times.

Impact of uncertainties on recovery behavior in a remanufacturing environment…

Remanufacturing of used products is an emerging business area, which is attractive from both an economic and an environmental point of view. Aims to investigate to what extent profit orientation in product recovery management will stimulate an environmentally conscious behavior in the sense that it promotes high recovery levels. This study also seeks to focus on a product recovery system where,…

Consumer responses to shelf out-of-stocks of perishable products

This paper aims to identify customer behavior with regard to out-of-stocks (OOS) of perishable products (focused on bakery bread) and the resulting inventory performance for these perishable products.

Business process innovation in the mid-1990s

Argues that today′s rapidly changing competitive environment, cost effectiveness and consistently high output quality are no longer enough to ensure corporate success. A company′s business processes must also be more responsive and flexible than those of its competitors. Innovative ways must be sought continuously to provide technology to support motivated, adaptable work groups dedicated…
