Abstract
Productions of the industries around the world depend on using equipment and machines. Therefore, it is vital to support the supply of equipment and spare parts for maintenance operations, especially in strategic industries that separate optimization of inventory management, supplier selection, network design, and planning decisions may lead to sub-optimal solutions. The integration of forward and reverse spare part logistics network can help optimize total costs. In this paper, a mathematical model is presented for designing and planning an integrated forward-reverse repairable spare parts supply chain to make optimal decisions. The model considers the uncertainty in demand during the lead-time and the optimal assignment of repairable equipment to inspection, disassembly, and repair centers. A METRIC (Multi-Echelon Technique for recoverable Item Control) model is integrated into the forward-reverse supply chain to handle inventory management. A case study of National Iranian Oil Company (NIOC) is presented to validate the model. The non-linear constraints are linearized by using a linearization technique; then the model is solved by an iterative procedure in GAMS. A prominent outcome of the analyses shows that the same policies for repair and purchase of all the equipment and spare parts do not result in optimal solutions. Also, considering supply, repair, and inventory management decisions of spare parts simultaneously helps decision-makers enhance the supply chain's performance by applying a well-balanced repairing and purchasing policy.

Abstract
Tourists are getting more aware of the environment. To determine the effectiveness of eco-tourism infrastructure management, the motivation and segmentation of demand for eco-tourism have been analysed using functional theory as a guide. The empirical analysis was conducted in the Dnipro, Zaporizhzhia, and Kherson regions. 382 surveys were obtained by random sampling. To make the data analysis, factor analysis and non-hierarchical segmentation were performed. The results indicate that there are several eco-tourism motivational aspects including self-development, interpersonal relationships, defence functions, building personal relationships, reward, and appreciation from nature. Three different segments of eco-tourists were also identified based on their motives related to nature, reward, and escape. Characteristics of different segments were also specified. This study will help government agencies and private companies improve their travel content and develop more effective marketing plans.
The research has shown that in most cases, the success of any project is in cooperation between NGOs, locals, authorities, and the private sector. The optimal level of local participation is determined by the specifics and scale of each project, which may focus on individual villages or several communities that experience any impact of tourism.
The economic essence of the concept of tourism motivation has been improved, which is defined as a set of needs that affect a person in the process of participation in tourism activities and are a central factor in the decision-making process. Studying the most important motivations of eco-tourists in the region, three groups of motives have been identified: cultural and educational activities, proximity to nature, health and rehabilitation measures.

Abstract
The Project Management Body of Knowledge (PMBOK) is a widely used model of project management based on prior experience. This standard does not distinguish between small and large projects, but small projects, with their limited schedules and budgets, face challenges using the extensive structure proposed by this standard. It has been suggested that the standard can be adapted to each project within its specifications; however, the tailoring procedures are complex, time-consuming, and at times impossible to apply to small projects. The present study examined whether or not the PMBOK is an appropriate model for small projects. To address this issue, a questionnaire was prepared and sent to 134 professional project managers. Analysis of the data confirmed that the assumption that PMBOK is a challenge to small projects was not contradicted. Most participants agreed that the procedure should be tailored to prioritize the standard tools and guiding techniques, in addition to the knowledge areas, for small projects.

Abstract
The essence of the economic security of the Ukraine's agricultural sector, its role in further globalization, as well as the trends of changes in key indicators of economic security till 2024 are considered in the article. The economic security of the agricultural sector is determined by the authors as an important component of the economic security of a country, it provides the state of a system (as a whole or individual entities), which in conditions of permanent influence of external and internal factors ensures the stability and progressive development of the agricultural sector providing conditions for preservation and further reproduction of resource potential, guarantees food security, promotes the development of rural areas.
The emphasis is focused on the special role of food security in the context of achieving the Global Sustainable Development Goals.
The key indicators of achieving the Sustainable Development Goal 2 "Overcoming hunger, achieving food security, improving nutrition and promoting sustainable agricultural development" are analyzed. The positive dynamics is established for the following indicators: Productivity labour in agriculture; Index of agricultural products; The share of agricultural lands under organic production in the total area of this year lands; The consumer price index for food. Other indicators show that Ukraine lags far behind the targets.
The need to form a unified approach to the management of economic security of the agricultural sector has become the basis for the development of conceptual foundations for the strategy of economic security of the Ukraine's agricultural sector in the context of globalization. The implementation of this strategy will strengthen further the food security.

Abstract
Supply chain management is one of the requirements for achieving economic growth in any supply chain. If managers' decisions are optimally allocated, it will be possible for companies and industries with a competitive and profitable advantage to grow and develop. The main desire of any company for survival is to minimize costs and maximize profitability. Due to the increasing complexity and dynamics of the situation, decision-making in this area requires more advanced analytical methods. Accordingly, the Real options theory has emerged, which introduces a new way of thinking about investing, especially in conditions of uncertainty. In this paper, a multi-period model is considered that examines the demand uncertainty in each period and also uses the Real options theory to seek the optimal strategy for investors in conditions of uncertainty and the effect of investors’ discretion on it. Using a decision tree to estimate the probable demand in each period and using Monte Carlo simulations to identify the lowest cost scenario in each period, the model has been solved in this research. In the case of the uncertainty parameter, sensitivity analysis is performed, and under different values of this parameter, the obtained result is evaluated and validated. And the extension of outsourcing will increase the company’s profitability and meet higher demand and lower costs.

Abstract
A coalition loyalty program (CLP) is a business strategy employed by for-profit companies to increase or retain their customers. One of the operational challenges of these programs is how to choose the mechanism of coordination between business partners. This paper examines the role of revenue sharing contracts in the loyalty points supply chain of a CLP with stochastic advertising-dependent demand where the program operator (called the host) sells loyalty points to the partners of the program. The purpose of the study is to examine the effect of this coordination mechanism on the decisions and profits of the members of the chain using the Stackelberg game method and determine whether the presence of revenue sharing contracts benefits the chain members when the advertising is done by the host and when the advertising cost is shared between the host and its partners. The results show that when the host gives bonus points to end customers (advertising), revenue sharing contracts become a powerful incentive for the profitability of the host and its partners. The findings provide new insights into the management of CLPs, which can benefit business decision-makers.

Abstract
This article develops an integrated model of transmitting strategies and operational activities to enhance the efficiency of supply chain management. As the second objective, this paper aims to improve supply chain performance management (SCPM) by employing proper decision-making approaches. The proposed model optimizes the performance indicator based on SCOR metrics. A process-based method is utilized for high-level decisions, while a mathematical programming method is proposed for low-level decisions. The suggested operational model takes some major supply chain properties such as multiple suppliers, multiple plants, multiple materials, and multiple produced items over several time periods into account. To solve the operational multi-objective optimization model, a goal programming approach is applied. The computational results are explained in terms of a numerical example, and a sensitivity analysis is performed to investigate how the performance of the supply chain is influenced by strategic scenario planning.

Abstract
Not much attention is given to the financial performance of non-oil firms in oil producing economies as the focus would be on firms operating in the country’s major industry. However, fluctuating oil prices have made their importance to the economy more evident as oil producers start to diversify and move away from reliance on oil as a major source of revenue. Fluctuating oil prices cause enormous pressure on oil corporations’ bottom line, the expansion of non-oil enterprises has. The non-oil sector's profitability strategy is a major challenge for non-oil enterprises looking to contribute to the economy. The study's objective in the context of non-oil firm profitability is to analyse research conducted over the previous two decades to understand the future orientation of non-oil firms in oil-producing nations. We utilised the PRISMA statement 2020 and gathered records from Web of Science and Scopus. The final 46 articles were included for the review, and VOS viewer software was used to categorise the results. This is a comprehensive review exploring profitability of non-oil firms from the contexts of firm size, market share, governance structure and capital management. The paper concludes with suggestions for further research on firm profitability in relation to the economy in which it operates. The study identified three significant streams: firm size, capital management and profitability. However, results indicate that there would be a positive link between business size and profitability. In addition, capital management is a critical component in maximising firm profitability, and the board of directors is a crucial determinant identified in the research. Finally, results show that the elements determining profitability remain a significant issue for academics.

Abstract
In developing countries, Human Resources (HR) is considered one of the most important factors that lead to the improvement and successful organization of employee performance. Human Resources Management (HRM) practices play an effective role in this performance, as this is evident through the impact of talent management on HRM practices, which leads to increasing and improving the production process for employees and making them possess high quality. Given the importance of this topic, the current study aims to determine the impact of the moderating role of Talent Management (TM) on HRM practices, which include good training, recruitment, performance evaluation, and remuneration system, on the institutional performance (IP) of Jordanian pharmaceutical companies. The study population includes employees of 13 pharmaceutical companies listed on the Amman Stock Exchange in Jordan. A random sample of 250 employees was taken. An electronic questionnaire was sent to the employees via e-mail. The 216 valid questionnaires were found, and the response rate was 86%. Two approaches, descriptive and analytical, were used due to their suitability to the nature of this work. The results obtained indicated that there is a significant positive impact of HRM practices (recruitment, training, performance evaluation, and remuneration system) on IP in Jordanian pharmaceutical companies. In addition, it was found that there is a positive impact of the moderating role of TM on the relationship between HRM practices and IP in these companies. Our study recommends that HRM practices can be used as strategic tools to align with long-term goals, invest in high-potential employees, provide performance growth opportunities, and create a collaborative work environment.

Abstract
The growing online marketplace has opened a plethora of opportunities for businesses across various industries. Manufacturers, seeking to bypass intermediaries and directly reach end-users, have been increasingly adopting online sales channels in addition to their traditional retail sales. A key challenge, however, lies in determining optimal pricing strategies and advertising investments for both manufacturers and retailers while considering various constraints. This study contemplates a two-echelon supply chain model involving one manufacturer and two retailers. The manufacturer sells its product both through retailers (offline channel) and directly to consumers via an online channel. The model features both global and local advertising. The influence of global advertising is realized through distinct advertising channels, each with a unique impact on demand. To further motivate retailers, the manufacturer contributes to the cost of local advertising. In response to these challenges, this research formulates a bi-level model and employs the concept of Variational Inequalities to solve it. The model also contends with production capacity and budget constraints, leading to a Generalized Nash-Stackelberg game. The validity of the model and the efficacy of the solution method are assessed through numerical experiments performed. Finally, a set of valuable managerial insights are provided.

Abstract
Life cycle assessment (LCA) is a valuable tool not only for analyzing the environmental impact of a product but also for assisting in early-stage product development before incurring scaling-up costs. When validating a new process or project, it may be constrained to align with existing regulations or standards. Therefore, combining LCA with other applicable standards is essential to demonstrate the project's feasibility. In this regard, the water quality index (WQI) and Water Exploitation Index (WEI) provide additional information that reflects the overall water quality at a specific location and time. The objective of this study is to utilize the LCA framework in conjunction with the Malaysia WQI and WEI to protect the water quantity and water quality of the river. A negative change in the WQI score indicates that the current effluent from the process is degrading the river's classification, rendering it undesirable and necessitating a reduction in concentration. The findings demonstrate that the method for determining effluent requirements for a water treatment system is straightforward and replicable. Such an approach could be employed, for example, in an environmental impact analysis of a project to verify its viability.

Abstract
Green human resources management (GHRM) represents the process of generalizing and incorporating various environmental practices in the field of HR policy and is considered one of the most important elements of supporting sustainable development. Therefore, companies today must flexibly determine pro-environmental HR practices and the extent of their impact on sustainable development. This study aimed to determine GHRM practices for Jordanian service companies listed on the Amman Stock Exchange to promote sustainable development. The study data was collected using the analytical and descriptive methodology. A random sample was selected including 383 administrative employees in 139 Jordanian service companies. Data were collected using an electronic questionnaire and analyzed using the Statistical Package for the Social Sciences (SPSS). The statistical results showed that there is a strong positive relationship to the impact of GHRM in promoting sustainable development for Jordanian service companies. Based on the results, the study recommended the necessity of service companies adopting the concept of GHRM and its impact on sustainable development. It also recommended that the organization should actively work to promote constructive transformation within societal institutions and spread knowledge and awareness related to the impact of GHRM on sustainable development and thus call for its advancement.

Abstract
The construction industry is one of the high-demand industries related to business and projects. Robust materials management that is subject to inventory management is the highest factor to enhance the Supply chain management (SCM) performance that will indicate the project's success within the complexity of the project. This research aims to measure the performance of Supply Chain Management at PT Cahaya Amal Taqwa as a new housing developer who focuses on subsidized housing that faces a project delay because they have less data documentation and analysis from previous projects. The issue is most newcomer construction projects never analyze and measure their supply chain management (SCM) which leads them to confusion about the project improvement. The research uses the Supply Chain Operational Reference (SCOR) method to know how much inventory management impacts supply chain management performance and how it overcomes the issues. Most studies only measure the SCM performance and show which aspects need to be developed without any scheme of solution offered. This research presents the scheme of improvement for the inventory model and provides forecasting for the whole SCM performance after the implementation of a new model of inventory management. The findings confirm that inventory management significantly impacts the whole supply chain management performance in the construction industry. The development of a solution system brought comprehensive results by classifying KPIs for inventory management and an interdependence network was created to define the new model of inventory system for the solution. This research proves that improving an aspect will impact significantly the whole SCM performance instead of improving KPIs one by one.

Abstract
The incorporation of sustainable practices becomes crucial as firms transition from Industry 4.0 to Industry 5.0. Therefore, this systematic review explores the relationship between the two sustainability approaches; Green Human Resource Management (GHRM) and Green Supply Chain Management (GSCM) using peer-reviewed studies from 2016-2023, retrieved from Scopus and Web of Science databases. 2016 marks the starting point as the first relevant paper emerged in the literature in that year. The PRISMA approach was used to identify relevant studies, resulting in the inclusion of 30 studies for analysis purposes. The study reveals a growing interest in understanding the relationship between GHRM and GSCM practices and their impact on sustainable performance. The majority of reviewed studies utilized quantitative survey methods, suggesting the need for future research utilizing qualitative and mixed methods for gaining deeper insights. The review indicates that most studies are conducted in emerging countries, and there is a significant gap in research on the relationship between GHRM and GSCM practices in other context. Finally, the study provides valuable insights for practitioners and researchers, emphasising the importance of integrating GHRM and GSCM practices for a sustainable competitive advantage.
