Holding together logistical worlds: Friction, seams and circulation in the emerging ‘global warehouse’

This paper examines logistics in the space of action between production and consumption to provide (1) a rethinking of logistical power, not as seamless flow but through seam space and friction, and (2) a re-conceptualisation of cargo mobilities, as the dynamic articulation between things being freight cargo, and being products and goods. The paper uses empirical research on cargo movement in Northern Europe to reveal the frictions resulting from freight cargo’s spatial ordering and from systemic imbalances in trade flows. It shows the multiple lines of friction produced by and productive of cargo mobilities across maritime and terrestrial space. It argues that logistics is an art of accommodating this and creating competitive advantage through making interruptions, discontinuities or seams in the spaces of flow. This is done through different temporal logics of ordering physical cargo sequenced across maritime and terrestrial space. The paper further shows the frictions between the physical spaces and flows of freight and the corresponding code-space and data flows. Bespoke corporate systems translate freight cargo to data and provide visibility to actors such that logistical and regulatory work can be anticipated and planned. Yet they do so through specific lines of sight. Bespoke systems also create seam spaces between networks as they simultaneously make frictions between rival corporate systems. The effect is to generate a contested, fractured space in which at stake is whether logistics works to further the interests of lead actors in the distribution chain linking up the global factory or as a tool of supply chain capitalism that spans continents and connects material supply to consumer, in which logistical actors increasingly perform the role of contractors in a global warehouse.

Integrating supply chains for emergencies and ongoing operations in UNHCR

Humanitarian organizations (HOs) often base their warehouse locations on individuals' experience and knowledge rather than on decision-support tools. Many HOs run separate supply chains for emergency response and ongoing operations. Based on reviews of humanitarian network design literature combined with an in-depth case study of United Nations High Commissioner for Refugees (UNHCR), this paper presents a warehouse location model for joint prepositioning that incorporates political and security situation factors. Although accessibility, co-location, security, and human resources are crucial to the practice of humanitarian operations management, such contextual factors have not been included in existing network optimization models before. We found that when quantified, and modeled, such factors are important determinants of network configuration. In addition, our results suggest that joint prepositioning for emergency response and ongoing operations allows for expansion of the global warehouse network, and reducing cost and response time.

A Spare-Part Distribution Management Model for Diesel Engine Industry

Under the analysis of the current situation and existing problems related to the spare-part distribution management of diesel engine industry, especially the incoordination between service stations and agents, the paper establishes a model featured as the multi-level warehouse, with a view of integrating the information of the whole chain and all levels of diesel engine industry from global warehouse, marketing and basic data, and effectively solving the problems regarding the distribution management of diesel engine industry. In the end of the paper, the implementation of the model in a case company is specified.

An integrated model for warehouse and inventory planning

The purpose of this article is to evaluate the value of integrating tactical warehouse and inventory decisions. Therefore, a global warehouse and inventory model is presented and solved. In order to solve this mathematical model, two solution methodologies are developed which offer different level of integration of warehouse and inventory decisions. Computational tests are performed on a real world database using multiple scenarios differing by the warehouse capacity limits and the warehouse and inventory costs. Our observation is that the total cost of the inventory and warehouse systems can be reduced drastically by taking into account the warehouse capacity restrictions in the inventory planning decisions, in an aggregate way. Moreover additional inventory and warehouse savings can be achieved by using more sophisticated integration methods for inventory and warehouse decisions.
