“…This implies that the issue of sustainability should be placed at the forefront of multimodal freight transport especially as there a lot more factors to be considered and addressed if multimodal freight transport is to be operated optimally. This view is supported by Carlier et al [9] who argued that the aggregated performance of a multimodal transport system cannot be fully understood from the separated performances of the component systems. Interestingly, sustainability of freight transportation is still subject to minor consideration, on the grounds that financial interests are frequently positioned much higher than social or ecological objectives.…”

“…This type of complexity can be multiplied with the use of multiple modes with the associated interface with several regulatory bodies, legislative bodies, financial systems, technology, service providers and varying human behaviours. Several studies have shown that multimodal transportation evolved as a combination of numerous transport modes aimed at improving trading efficiency [1,9]. This combination further complexes the use of multimodal freight transport, resulting in both positive (short transport time, reduced cargo damage, inventory reduction, improved quality of freight) and negative (safety, traffic congestion, infrastructural damage, fuel consumption, air pollution, noise etc.)…”

Due to Globalisation in trade, the development of multimodal cargo shipments and the related transport needs have created a range of challenges. Interestingly, sustainability of multimodal freight transportation is still subject to minor consideration, on the grounds that economic interests are frequently positioned much higher than social or environmental objectives. This proposed Research plan is needed to assess whether and to what extent the multimodal freight system is achieving the results in the sustainability dimensions: economic, social and environmental. Thus, it will carry out a critical appraisal of the multimodal freight transportation sector to provide an up to date knowledge on the sustainability challenges and the potential solutions through doctoral research. This paper structured to present a review of existing literature on freight transportation and multimodal freight transport highlighting the sustainability concerns with multimodal freight transport systems. It also highlights the gaps in knowledge with a justification on the need to address these gaps for the system to function optimally. It also covers the methodology that would be applied and the sources of data that would be reviewed to ensure the aim and objectives are clearly addressed. The paper concludes by discussing the significance of the expected findings in the light of sustainability in multimodal freight transport to the academia, policy makers and the freight transportation industry.

“…But some mathematical approaches to solving the problems in the mentioned works were used in the developed algorithms. Different approaches are used for mathematical modeling of transport systems, including the use of graph theory [7], [8], [9], [10], [11]. In our view, the approach to mathematical modeling of combined (multimodal) transportations described in the work [12] is more appropriate.…”

This research aims to study the relationship between parallel processing efficiency and several nodes on a single board cluster using a mathematical model, approximating least squares. This research tested on the Raspberry Pi single-board in the form of a high-performance computing system. It divided the tasks that need to be processed in each particular part and sent it to each unit to process simultaneously via the MPI (Messaging Passing Interface). This process is the standard division of work with communication between processors in the form of messages on the cluster system. It consists of eight nodes of Raspberry Pi. It measures the instruction set's ability to perform decimal operations per second or Floating-point Operation Per Second (FLOPS) with High-Performance Linpack Benchmarks (HPL). As a result, the efficiency of the ability to process instruction set in decimal per second increases the performance continuously when increasing the number of the node on the cluster. Which corresponds to the mathematical model obtained f(x) = 1.0684x^(0.8256).It shows a relationship between parallel processing performance values and the number of nodes on the cluster and can be estimated with the mathematical model above.
