Multiple Case

Purpose The purpose of this study is to explore warehouse configuration in omni-channel retailing. Design/methodology/approach A multiple case study is conducted with six large omni-channel retailers from three different sectors. Findings The study shows an increase in the number, variation and frequency of flows passing through omni-channel warehouses. Along with an increased variety of stock keeping units (including singles vs multipacks), there is an increase in the complexity of planning and coordination of order fulfillment. Retailers test a mix of different solutions for storage and picking and partly shift focus to advanced sorting operations. The companies already have or plan to invest in substantial automation systems, which emphasize the importance of capturing and using accurate master data. Research limitations/implications The study highlights the need to understand the interrelations and co-development of configuration elements in omni-channel warehousing. The findings also suggest that a successful transformation requires increased collaboration with upstream and downstream partners. Conceptual models are developed to illustrate strategies and development paths in omni-channel warehousing, and suggestions for future research are summarized in a research agenda. A research limitation is the focus on Swedish retailers in three sectors (fashion, consumer electronics and DIY/construction material). Future studies can include additional sectors, extend the geographical scope and explore cross-regional differences. Practical implications As one of the few deeper case studies on omni-channel warehousing, practitioners will find new configurations described and analyzed here. Along with conceptual models, a synthesis of challenges and potential solutions are presented to support retailers’ practical analysis and decision making. Originality/value This is one of the first multiple case studies that go deeper into omni-channel warehouse configuration, which is of increasing importance to both scholars and practitioners in the field.

This paper summarizes a theoretical study undertaken to provide a better understanding of the consequences of poor bond on flexible pavement performance. The main objective of this paper is to investigate the influence of bond on the performance of Malaysian road. The pavement structure of Malaysian road was analyzed using a layered linear elastic program, BISAR 3.0 taking into account different state of the bond at the interfaces of the pavement layers and a static horizontal load in addition to the standard vertical dual load. The results indicate that the condition of the bond between the wearing and binder course can reduce the life of the pavement by up to 64%. On the other hand, the results also indicate that the condition of the bond between the binder and road base course, which was made up from asphaltic materials can reduce the life of the pavement by up to 68%.

The internationalization of dominant market leaders such as Haier (China), Tata Group (India) and CEMEX (Mexico) in emerging economies has attracted immense amounts of interest among academic researchers. A less-explored area is how non-dominant, second-movers venture into the international market. How do small players connect with foreign customers while operating in the shadows of the industry leader? What decisions are serendipitous and what actions are deliberate? What are the key environmental factors and internal decisions that propel a secondary player to place more chips in the international market? This case study addresses these questions using an example of a construction material manufacturer from Southeast Asia. It is suitable as a discussion starter in an international business class, especially for topics such as entry strategy, export marketing and the organization of international business.

Environmental and economic cycles under varying geopolitical uncertainties can lead to unsustainable patterns that significantly and negatively affect the welfare of nations. With the ever-increasing negative environmental and economic impacts, the ability to achieve sustainability is hindered if the implications are not properly assessed in challenging geopolitical crises. The infrequent and fluctuating nature of these challenging geopolitical settings causes disregard and neglect for exploration within this issue. In this study, a comparative life cycle assessment was conducted as a method to evaluate the environmental and economic impacts of construction material flow across country boundaries. Based on the results found from the life cycle assessment, an environmental forecast and sensitivity analysis were established. Considering the State of Qatar as a case study, asphalt and bitumen, cement, limestone, sand, and steel were analyzed from gate-to-gate depending on transportation mode and distances used within both the pre-crisis and post-crisis sub-periods, comparing carbon emissions and costs. The results showed that the mode of transport plays a significant role in terms of carbon dioxide emissions as opposed to distance traveled. However, the increase in distance coupled to the majority shift from land to sea-based transport resulted in an overall increase in carbon emissions and costs post-crisis. In addition, the analysis of the environmental and economic impact assessment using the average CO2 equivalent (CO2-e) per kilogram and the unit price of the five primary construction materials has shown a significant, 70.68% increase in global warming potentials (GWP) after the crisis, coupled with an increase in the overall cost. An assessment of environmental and economic impacts during geopolitical uncertainties allows for the significant ability to realize sustainable measures to greatly reduce economic and environmental degradation.

The fundamental focus of this qualitative study is to explore the contributing factors responsible for construction material shortage specifically in major cities of Pakistan's such as Lahore, Peshawar, and Islamabad. Further, the study has concentrated to discover the potential remedies to overcome the barriers resulting in a shortage of construction material availability. Data sampling methods are utilized to apprehend the participant’s opinion. The participant’s opinions were recorded to make them efficiently analyze through inductive thematic investigation. For sound results, the current condition of material shortage, relevant reasons, and deficiency of key items are examined in detail. The research findings proposed that the unavailability of materials is associated with the deficiency of a customary delivery system, fluctuations in demand, complications in the import of materials, significant expense, limited share portion in raw material, constrained suppliers of crude material, political clashes, administrative limitations, and maintenance of realistic prices. The result obtained, the recommended remedies are to extend flexibility and guideline for the manufacturers, the maintenance of realistic prices, and boosts the record control system, improvement in stock control framework, and establishment of a reserve system in the country. This study believes in contributing to the shortage of construction materials: a case study of Lahore, Islamabad, and Peshawar, Pakistan
