Abstract
This paper presents a framework for the design of warehouse layout to organize the design process, facilitate the task of designers, and highlight important design issues to help warehouse managers make informed decisions. The framework accounts for several factors and operations of warehousing in the design, and addresses design decisions required to respond to them. It attempts to develop a layout that has several characteristics such as modularity, adaptability, compactness, accessibility, flexibility, and distribution of movement to enable it to respond to changing conditions, improve space utilization, and reduce congestion and movement.

Abstract
Purpose
Creating a real-time data integration when developing an internet-of-things (IoT)-based warehouse is still faced with challenges. It involves a diverse knowledge of novel technology and skills. This study aims to identify the critical components of the real-time data integration processes in IoT-based warehousing. Then, design and apply a data integration framework, adopting the IoT concept to enable real-time data transfer and sharing.
Design/methodology/approach
The study used a pilot experiment to verify the data integration system configuration. Radio-frequency identification (RFID) technology was selected to support the integration process in this study, as it is one of the most recognized products of IoT.
Findings
The experimentations’ results proved that data integration plays a significant role in structuring a combination of assorted data on the IoT-based warehouse from various locations in a real-time manner. This study concluded that real-time data integration processes in IoT-based warehousing could be generated into three significant components: configuration, databasing and transmission.
Research limitations/implications
While the framework in this research was carried out in one of the developing counties, this study’s findings could be used as a foundation for future research in a smart warehouse, IoT and related topics. The study provides guidelines for practitioners to design a low-cost IoT-based smart warehouse system to obtain more accurate and timely data to support the quick decision-making process.
Originality/value
The research at hand provides the groundwork for researchers to explore the proposed theoretical framework and develop it further to increase inventory management efficiency of warehouse operations. Besides, this study offers an economical alternate for an organization to implement the integration software reasonably.

Abstract
Warehousing remains the most frequently outsourced logistics activity, but empirical research on the third‐party selection process for warehousing remains scarce. The main goals of this research were to identify the most critical factors to customers during third‐party warehousing selection and to compare the perceived performance levels of national and regional third‐party firms on each of the selection criteria. Surveys were sent to warehousing customers in several industries. Responsiveness to service needs, quality of management, and track record of ethical importance were rated by customers as the most important selection criteria. Results indicate that respondents also rated the performance of the typical regional third‐party warehousing firm as significantly better than national firms on six different criteria while national firms were rated significantly higher on only one criterion. It is hoped that this research can provide guidance to logistics managers as they evaluate third‐party warehousing options.

Abstract
The design of logistical systems historically has been responsive to the economic climate and market requirements of the times. When the cost of money rose dramatically during the 1960s, companies reacted by reducing the number of stocking points in their distribution systems. This was a proper response considering that capital costs represent a high proportion of inventory carrying costs. On the other hand, warehouse storage and handling, transportation, and production costs had much smaller relative increases. Consider just how dramatic the warehousing change was for two companies.

Abstract
Purpose
Distribution network design involves a set of strategic decisions in supply chains because of their long-term impacts on the total logistics cost and environment. To incorporate a trade-off between financial and environmental aspects of these decisions, this paper aims to determine an optimal location, among candidate locations, of a new logistics center, its capacity, as well as optimal network flows for an existing distribution network, while concurrently minimizing the total logistics cost and gas emission. In addition, uncertainty in transportation and warehousing costs are considered.
Design/methodology/approach
The problem is formulated as a fuzzy multiobjective mathematical model. The effectiveness of this model is demonstrated using an industrial case study. The problem instance is a four-echelon distribution network with 22 products and a planning horizon of 20 periods. The model is solved by using the min–max and augmented ε-constraint methods with CPLEX as the solver. In addition to illustrating model’s applicability, the effect of choosing a new warehouse in the model is investigated through a scenario analysis.
Findings
For the applicability of the model, the results indicate that the augmented ε-constraint approach provides a set of Pareto solutions, which represents the ideal trade-off between the total logistics cost and gas emission. Through a case study problem instance, the augmented ε-constraint approach is recommended for similar network design problems. From a scenario analysis, when the operational cost of the new warehouse is within a specific fraction of the warehousing cost of third-party warehouses, the solution with the new warehouse outperforms that without the new warehouse with respective to financial and environmental objectives.
Originality/value
The proposed model is an effective decision support tool for management, who would like to assess the impact of network planning decisions on the performance of their supply chains with respect to both financial and environmental aspects under uncertainty.

Abstract
In the mid‐1970s Mothercare decided to establish a new distribution centre and mail order warehouse; a number of alternative order picking systems were considered for the company's world‐wide mail order operation. This article examines the various alternatives and describes the system which was finally selected — a carousel storage and selection arrangement. Current performance statistics of the system are provided which are related to Mothercare's sales volumes.

Abstract
Purpose
The purpose of this paper is to investigate the use of freight containers to store relief items instead of operating a permanent warehouse building.
Design/methodology/approach
A mathematical model is developed to determine the location and quantity of containers as well as the type and amount of relief supplies to store in order to investigate the practicality of using freight containers for storage. The model is tested using earthquake risk data, estimates of population under risk, and the distances between cities. An experimental study is performed using Turkish Prime Ministry Disaster and Emergency Management Presidency (abbreviated as AFAD in Turkish) data for total number of relief supplies.
Findings
Considering the earthquake risk of possible locations, the results of the study indicate the target locations for containers. The idea of using containers as storage facilities helped beneficiaries to be reached within a short distance and in an efficient way.
Research limitations/implications
The presented model is not implemented in real life disaster relief operations even if it is tested with real earthquake risk, demand and distance data.
Practical implications
To apply this model in practice, the container locations within cities should be determined and managerial operations such as maintenance, environmental, and security planning have to be considered.
Originality/value
This study presents the first analysis of three sub-topics’ intersection: warehousing, pre-positioning in disaster relief, and containerization. To the best of authors’ knowledge, containers have not been considered for storage of relief items in humanitarian logistics before.

Abstract
Suggests that, in recent years, remarkable progress has been made in the development of the topological design of logistics networks, especially in the warehouse location problem. Extends the standard warehouse location problem to a generalization of multiproduct capacitated warehouse location problem, as opposed to differentiated variations of a single‐product warehouse location problem, where each warehouse has a given capacity for carrying each product. Presents an algorithm based on cross‐decomposition, to reduce the computational difficulty by incorporating Benders decomposition and Lagrangean relaxation. Computational results of this algorithm are encouraging.

Abstract
Freight consolidation across time and customers, use of warehouses, and direct LTL distribution systems are compared on distribution costs and delivery times for selected product characteristics and demand patterns. The results can assist managers in determining whether using freight consolidation is a viable alternative to direct shipments from plants or warehouses.
Abstract
Purpose
Large supermarkets, chain stores and enterprises with large-scale warehousing put forward higher standards and requirements for the automation and informatization of warehouses. As one of the fast-growing commercial supermarkets in China, the traditional warehouse management mode has restricted the rapid development of Yonghui Superstores to a certain extent. The purpose of this paper is to find out how the existing warehouse mode can be changed and to solve the existing problems of warehouse management of Yonghui Superstores.
Design/methodology/approach
This research puts forward construction of warehouse center, which is based on radio frequency identification (RFID) and sensor technology, then designs the model for receiving, storage, operations management, distribution and outbound to solve the existing problems of warehouse management of Yonghui Superstores.
Findings
What technologies should be adopted to meet storage requirements? How to monitor the storage environment in real time and improve the operation and management level of the warehouse? This study found that building a warehouse center based on RFID and sensor technology was a good solution.
Research limitations/implications
The Yonghui Superstores warehouse center model lacks corresponding simulation experiments, and the investment and income are difficult to estimate quantitatively.
Practical implications
This paper has designed and discussed the warehouse center model based on RFID and sensor technology, which provides a few references for the actual investment and construction of a warehouse center. In addition, the warehouse center model has strong generalized applicability and could be widely used in various enterprises.
Social implications
The warehouse center could improve the warehouse management level of Yonghui Superstores and change the traditional warehouse management mode. To some extent, it improves the enterprise flexibility of the market, which will be of great significance to improve business efficiency and enhance brand image and competitiveness.
Originality/value
This study takes Yonghui Superstores as a case to analyze the problems of warehousing management in detail and then designs a warehouse center based on RFID and sensor technology. The study discusses the location and distribution, software and hardware selection, benefits evaluation, significances and return on investment, which makes the warehouse center model versatile, technically feasible and economically applicable.
