“…Routing optimization is also shown to be very useful in improving the environmental impact [28][29][30], while the decisions on supply lead time, reorder quantities, and storage equipment also have an impact on costs and emissions [31]. High frequent deliveries with trucks result in high emission during transport but low emission during the storage process [32].…”

The concept of Industry 5.0 provides a human-centered, sustainable, and resilient manufacturing system with a high emphasis on green technologies. This paper will examine the current use and perception of the green and digital technologies in the internal and external transport systems of Croatian manufacturing companies, relying on the continuous work of the authors in the field of local manufacturing industry development and digitalization. On a sample of 112 companies, statistical analysis of the results has shown that the greatest challenge in the digital technologies implementation is the unavailability of the technology on the market and employee resistance to change. The companies perceive benefits of renewable resource usage in internal transport in the rise in environmental awareness and increased flexibility, while the productivity increase and human safety improvement are the crucial reasons for the digitalization of internal transport in Croatian manufacturing companies. In external transport, the use of renewable energy sources is very rare, due to high price and low endurance of the vehicles, but the main reasons for its future possible implementation are environmental awareness, profitability, and sustainability. The majority of the companies in Croatia are still not familiar with Industry 4.0 or 5.0 concept but have shown a high interest for digital and green technology implementation to enable sustainable future development.

Industry 5.0 is a human-centred concept of industrial development towards the sustainable and resilient system presented by the European Union which aims to become the global both innovation and industrial leader. It should overcome the barriers of the previously presented Industry 4.0. This paper presents the research conducted in the 112 Croatian manufacturing companies, dealing with their awareness level of the Industry 5.0, as well as the use of green and digital elements in logistics activities. The results have shown that the awareness of the digital concept of both Industry 4.0 or 5.0 remains low, but the companies are more open towards the implementation of the green elements than the digital ones, with the potential for future development recognized.

The paper addresses the green sequencing and routing problem, which consists in determining the best sequence of locations to visit within a warehouse for storing and/or retrieval operations, using a fleet composed of both electric vehicles, e.g., equipped with a lithium-ion battery, and conventional vehicles, i.e., with an internal combustion engine. We present a Mixed-Integer Linear Programming formulation to the problem and propose two matheuristics based on suitable decompositions of the mathematical formulation. The two matheuristics have been tested on a pool of small-medium size instances and their performance has been compared to the one of a third matheuristic, previously proposed for the case of conventional vehicles only and here suitable extended to deal with the green aspects of the problem. The performed analysis allowed one to identify the most promising matheuristic in terms of some standard computational indicators, i.e., computing time and percentage optimality gap, as well as in terms of some qualitative aspects of the solutions agreed with a reference company. Such a most promising algorithm has then been further tested to gather some technical insights on what makes the problem hard to solve, as well as to outline some managerial insights. Moreover, its performance has been tested on a pool of real instances comprising ordinary days (with a usual amount of operations to perform) and extremely busy days, showing its efficacy and efficiency also in the considered real application context.
