“…The mapping of movements must be carried out several times, on different working days at different hours, choosing the appropriate number of analyses to observe the performance of all warehouse activities (as if several inspections were being carried out) and analyze a sample of significant flows. During each inspection, smart tracking devices are used to localize forklifts and workers [29] and to trace on the planimetry the spaghetti corresponding to the observed movements. Aiming at objectively representing the flows of entities, it is preferable to use such devices rather than drawing diagrams manually.…”

“…Several devices can be used to automatically map resource movements in the system (cameras, smartwatches, position sensors, smartphones, etc.) [16,29,31]. However, using smartphones is particularly advantageous because it does not require large investments in IT technology to obtain a smart spaghetti mapping (nowadays, many companies already have company phones available) [7].…”

Warehouse management is a discipline that has gained importance in recent decades. In the era of the Digital Revolution and Industry 5.0, to enable a company to attain a competitive advantage, it is necessary to identify smart improvement tools that help search for warehouse problems and solutions. A good tool to highlight issues related to layout and resource flows is the spaghetti chart which, besides being used to minimize waste according to lean philosophy, can also be used to assess warehouse safety and reliability and improve the plant sustainability. This article shows how to exploit “smart spaghetti” (spaghetti chart automatically generated by smart tracking devices) to conceive improvements in the layout and work organization of a warehouse, reducing the risk of collision between forklifts and improving the operators’ safety. The methodology involves automatically mapping the spaghetti charts (searching for critical areas where the risk of collision is high) and identifying interventions to be carried out to avoid near misses. “Smart spaghetti” constitutes a valuable decision support tool to identify potential improvements in the system through changes in the layout or in the way activities are performed. This work shows an application of the proposed technique in a pharmaceutical warehouse.

This chapter presents a comparative analysis and review of indoor positioning systems, both from an algorithm and a technology point of view. It sheds light on the evolving landscape of location-based services within confined spaces. The review encompasses a diverse range of technologies employed in indoor positioning systems, including Wi-Fi-based systems, Bluetooth low-energy solutions, radio frequency identification technologies, ultra-wideband, inertial measurement units, visual-based systems, and sensor fusion approaches amongst many others. By summarising a multitude of research findings and technological advancements, the chapter offers insights into the strengths, limitations, and emerging trends within the field. Furthermore, it critically assesses the performance metrics of various indoor positioning systems, thus providing a comprehensive guide for researchers, developers, and practitioners. The comparative analysis delves into the practical implications of these systems, by considering factors such as design and deployment cost, power efficiency, and adaptability to different indoor environments. The main types of signal acquisition and position estimation techniques used in indoor positioning systems are discussed, while providing the advantages and disadvantages of each approach. This chapter aims to contribute to the advancement of indoor positioning technology, by offering valuable perspectives for future research directions and practical applications.
