This paper focuses on the problem of supplier portfolio selection where a company has to choose the best possible set of suppliers with respect to various constraints. An intuitive heuristic can suggest to use any of the methods for suppliers ranking and then to put the first one into the portfolio. If some required constraint is not met, then the second supplier according to the ranking is added, and so on, until all the constraints are satisfied. However, such approach can result in a non-optimal decision. The constraints can cause that a combination of the alternatives with lower rankings can be better, than some higher-ranked alternative from the perspective of feasibility. To build the optimization model, the authors of this paper use the PROMETHEE V method: a popular combination of multi-criteria decision making method PROMETHEE and mixed integer programming. However, it is shown that the original PROMETHEE V method, namely the logic under which an objective function is set, is not suitable here and leads to discrimination of suppliers with worse ranking. Therefore, a modification, which brings more reasonable results, is proposed in this paper. A numerical example is used to show the suitability of the proposed approach and compare the results with the original algorithm and also with one prior modification introduced by by other authors in the past. The analysis is further supported by a thorough sensitivity analysis using flexible and parametric programming.

The publication describes the development of a new method suitable for selecting an environmentally friendly packaging solution in B2C logistics, which is currently facing major challenges. The key for developing the new method is the fact that the selection process is greatly influenced by the ecological aspects of the supplier's solution and the efficiency of working with the proposed solution, as these are the key aspects of the future in logistics. In the results and discussion, we will focus on a specific company that currently uses 14-size variants of cardboard packaging. Based on our analysis, we reduced these to four variants and streamlined the process of ordering, handling and storage of cardboards. Using the OEE metrics, we calculated the feasibility of this solution, which was only at the level of 65% compared to the metrics set by the company's management. With the help of the suppliers, we have designed a new solution that was tested under the same conditions using the OEE metrics. In the test, we have reached the level of 98%, which means a 33% increase in efficiency. At the same time, this solution is highly environmentally friendly and does not use polypropylene adhesive tapes, which pollute the environment. We then compared the results and evaluated the best quotes for both types of cardboards. The newly designed solution is only 4.9% more expensive than the currently used type of cardboard. Based on the results achieved, we can conclude that the new method offers companies the most advanced approach to choosing a suitable solution for B2C logistics.

Freight transport plays an important role in meeting the domestic needs of the city's inhabitants. But when freight vehicles come into contact with city traffic, it has a negative impact on urban routes, such as extra traffic congestion, noise pollution, air pollution, etc. The aim of the study is to assess the impact of freight transport on the overall traffic of the city. A case study of the wholesale market of Ahmedabad has been considered as a study area. The freight trip models based on the trips attracted and produced by the market are developed on the basis of data collected from establishment surveys and freight vehicle driver surveys. Both the models developed in this study, FTA (Freight Trip Attraction) and FTP (Freight Trip Production), have R Square values of 0.799 and 0.715, respectively. The volume of freight vehicles contributing to the overall traffic flow is also measured by the traffic volume study. Through the data analysis and identification of the impact of freight transportation on city traffic, remedial measures are discussed to reduce the impact of freight transportation.

An analysis of the activities of leading transnational corporations (TNCs) for the period from 2000 to 2020 showed that the transformation of the world economic order leads not only to new rules for conducting international business, but also to the occupation of prevailing positions in the world market by TNCs engaged in the service sector. Therefore, the purpose of the study was a systematic analysis of the impact of intangible assets on the growth of the competitiveness of the service sector and the increase in their market capitalization, revenue and asset value. Based on an in-depth study of statistical data, the authors identified trends that led to an increase in the share of intangible assets in the value of companies; an analysis was made of the presence of TNCs in the service sector in the ratings for assessing the level of revenue and market capitalization (based on the Fortune Global 500); comparison of indicators related to intangible assets with the human development index and the business environment, formed taking into account the existing investment climate (based on AON Empower Results, GIFT, World Investment Report); identified the most promising sectors for the use of intangible assets. Based on the results of the study, uniform principles were formed according to which the management of intangible assets of TNCs should take place, in which an important place is occupied by the use of the potential of intangible assets and the advantages of the triple helix of innovations (education - business - government).

The key goal of the study is the formation of scientific and methodological approaches to the analysis of modern models of economic development of countries. The features of the models of economic development of countries, their types and specifics are considered, the transformation of indicators of economic development of the countries of the world in the context of global imbalances and volatility is argued. It is proved that the key factor in the sustainable development of the country is economic growth, which ensures the overall well-being of both a separate industry and the country's economy as a whole. The specificity of the transformation of key indicators of the economic development of countries is considered; this served as the basis for substantiating the scientific and methodological aspects of the multidimensional cluster analysis of the target indicators of the economic development of the countries of the world. The scientific and methodological aspects of the multidimensional analysis of the transformation of the target indicators of the economic development of countries were formed, which ensured the structuring of countries into groups of economic development, taking into account the specifics of their functioning and development strategies. The application of the developed approaches based on the economic and statistical multidimensional cluster analysis and indicators of economic development of the countries of the world can be applied in practice. The developed scientific and methodological recommendations will ensure the effectiveness of the formation of economic policies and strategies for the economic development of countries.

Automated parcel locker is a self-service technology to facilitate parcel collection and has been introduced in Malaysia in 2016. Although automated parcel lockers have advantages over home delivery, customers still prefer the traditional method. Subsequently, this study aims to explore the role of time constraint, supplier image, and openness to change toward online buyers' intention to use automated parcel lockers. Based on the stimulus-organism-response theory, the study conducted both an online survey and an on-site survey. Two hundred and sixty-five respondents’ data were used for data analysis, and the results indicate that time constraint has a negative influence on openness to change, and supplier image has a positive influence on openness to change. Openness to change was found to mediate the relationship between time constraint and intention to use and between supplier image and intention to use. Automated parcel lockers providers will benefit from the outcomes of this study.

The liberalization of the petroleum sector in Morocco has a significant effect for petroleum product distributors. Since the beginning of December 2015, fuel prices are freely determined. This event presents many constraints affecting the balance of the sector plus the competition among its economic players. As all fuel products are imported, we will be interested in the evolution by making forecasts of the price of fuels in the Moroccan market. In this context, our paper aims mainly to study the time series of diesel and gasoline in order to provide precise forecasts to the company and to respect the permissible error margin of 3%. To this end, the harmonic dynamic regression model through the proposed process approach yielded excellent forecasting results for the first quarter of 2017 with an average error margin of 1.617%. Compared to ARIMA model, the harmonic dynamic regression proves its strength manifested in the low rate of error. In addition, the assumption that the residuals are a Gaussian white noise has always been verified. The forecasts obtained are very crucial for managers to take good decisions at the strategic level.

Our structured literature review reveals the current state-of-the-art supply chain performance evaluation models (SCPEMs) from the last 21 years of research. Seventy related papers from the 2000 to 2021 time period were found to contribute by using ISI and SCOPUS databases. This paper has classified SCPEMs in terms of focus area and the perspective considered (financial and non-financial). With the analysis, these models’ applicability in today’s business environment pinpointed the most usable models and their current shortcomings. Findings disclose current SCPEMs limitations and misalignments with the emerging disruptive technologies observed in today’s supply chains. Given the findings, this study has highlighted the lack of overall supply chain performance evaluation and the failure to underline the underperforming decision criteria in the SC network. Therefore, to tackle these gaps, the authors have suggested visibility, leagility, collaboration, digitalization, sustainability, and integration as SCM characteristics to be considered in the future when developing a novel SCPEM. Finally, this study can be used as guidance for future studies.

This paper has a dual objective, to specify the logistical capacities of Moroccan Logistics Service Providers (LSPs) and to understand the process by which these capacities contribute to the logistical performance of LSPs. Methodologically, we used the qualitative approach based on a sample of sixteen LSP. The results of this research show that the main logistical capacities of Moroccan LSPs are flexibility and innovation, which respectively abound in reactivity/proactivity and technological innovation / administrative innovation. Similarly, "customer response" appears to be a purpose that overlaps with logistics performance. Thus, this variable mediates between flexibility and logistics performance. This study also tries to analyse the emergence of new moderating variables, particularly "logistics skills," which strengthen the relationship between innovation and customer response, and "communication with employees" as a support for maintaining performance logistics.

This article looks at the role of middleman relationships in a decentralized supply chain, considering a three-element structure consisting of an independent supplier, a distributor, and a producer. We study a model based on game theory that allows the analysis of the coordination of the three links, which evaluates qualitative criteria in their supply relationships, distribution, and reception of their operating preferences. The objective of the research is the construction of trust by analyzing the interrelationships of the three links for their consolidation, or not of the supply chain, using the Nash equilibrium, which allows summarizing satisfaction and loyalty throughout the supply chain. The set of Nash equilibria reflects that achieving satisfaction in the interrelationships between them is the main strategy to be followed by companies seeking to promote coordination within their operations. At the same time, we observe that only one agent is sufficient to maintain the flow of materials, i.e., the problem of the free-rider arises between us. In this study, five different equilibria are obtained, of which in four the supply flow continues within the chain, and in one equilibrium the relationship fails.
