An optimisation model for the warehouse design and planning problem

In spite of the importance of warehouses in the field of the supply chain management, there is not a single decision model that integrates all the decisions that concerns the warehouse design and planning problem. In this paper we discuss a mathematical programming model aiming to support some warehouse management and inventory decisions. Our aim is to address the complexity related to the modeling of the wareh...

An optimisation model for the warehouse design and product assignment and alloc...

Warehouse design and planning is a great challenge in the field of Supply Chain Management. In this paper we discuss an optimisation model aiming to support some warehouse management decisions. In particular a mixed-integer programming model (MILP) is presented to determine product assignment and allocation to the functional areas, as well as the size of each area. Our aim is to capture the trade-offs among the...

Concepção e planeamento de armazéns

Uma cadeia de abastecimento pode ser considerada como uma rede de entidades individuais que, colectivamente são responsáveis pela gestão de fluxos de materiais e de informação desde os fornecedores até ao consumidor final. Assim, a eficiência e eficácia destas redes é fortemente condicionada pelas operações em cada uma das entidades que a integram. Neste sentido, os armazéns proporcionam uma importante ligação ...

An integrated model for warehouse design and planning

Warehouse design is a field of interest for both practitioners and researchers that have attracted a lot of research attention in the last years. Nevertheless it remains a complex task with very few general models that capture the existing and often conflicting trade-offs of a warehouse system. Literature surveys show that most research efforts have been devoted to solve limited and well-defined problems rather...

An optimisation model for the warehouse design and planning problem

In spite of the importance of warehouses in the field of the supply chain management, there is not a single decision model that integrates all the decisions that concerns the warehouse design and planning problem. A number of warehouse decision support models have been proposed in the literature but considerable difficulties in applying these models still remain, due to the large amount of information to be pro...

Operational research models in warehouse design and planning

The design and operation of a warehouse involve many challenging decision problems. In this paper, a literature review on warehousing models is presented. Authors start with a hierarchy of decision problems encountered in setting up warehouse design and planning processes. Next, some operational research decision models and solution algorithms supporting decision making at each discussed level are presented. Th...

Integrated models for warehouse design and planning

Market competition requires continuous improvement in the design and operation of supply chains. Warehouse management is a field of interest for both practitioners and researchers and involves material, information and financial flow management in a highly dynamic environment. Designing and planning a warehouse (distribution centre) involve different levels of decision-making, with high levels of interactions a...

Integrated approaches to warehouse planning and operations

In this talk we discuss a tactical model recently available in warehouse literature. The model integrates the replenishment decision in inventory management, the allocation of products to warehousing systems and the assignment of products to storage locations in warehousing management. Our aim is to show the models’ potentialities and weaknesses when applied to a wide variety of problems and to identify challen...
