Our research aims at solving a solid waste management vehicle routing problem that integrates the three pillars of sustainability; environmental, economic, and social. More specifically, our approach intends to investigate the effect of different drivers’ health state on the different parameters in solid waste management networks, by estimating the probability of suffering from work-related injuries, using Markov’s Chain model. In addition, our approach extends the reality of the model by considering different parameters and variables that will improve its practicality, such as including different cost functions. Furthermore, to ensure sustainable business practices, our model aims at minimizing the CO2 emissions resulting from different types of waste vehicles. Also, the social factor was studied by considering drivers’ health condition, minimizing the risk of accidents facing drivers, and minimizing any deviation from balanced workload between drivers. The Non-dominated Sorting Genetic Algorithm (NSGA) was used to solve the developed model, due to its ability to tackle multi-objective vehicle routing problems in general, and Solid Waste Management Vehicle Routing Problems in particular. After solving the proposed model, results revealed the effect of driver’s health states on different cost functions, in addition to the negative impact of high travel distance and waste vehicle load on the health condition of drivers. Sensitivity analyses illustrated how different model variables and parameters interact with each other, in addition to the effect of travel distance and vehicle load on drivers’ health conditions. The execution of this model in the waste management sector yields many advantages for service providers, due to its ability to monitor the health condition of drivers at each node in the network. This results in productive healthy drivers carrying out operations, who can achieve financial success along with a healthy and safe working environment.
- ItemA FRAMEWORK STRATEGY FOR SUSTAINABILITY CONSTRUCTION WASTE MANAGEMENT: CASE OF WEST BANK, PALESTINE(An-Najah National University, 2024-04-06) Hareez, FirasThis study aims to develop a strategic framework for sustainable construction and demolition (C&D) waste management in the West Bank of Palestine. Currently, no regulatory system governs C&D waste, resulting in unsustainable practices like dumping and burning that degrade the environment and public health. Previous research provided initial estimates of waste quantities, but gaps remain regarding generation patterns, stakeholder roles, and barriers. The research uses a mixed-methods approach, including questionnaires with 100 professionals and interviews with 10 interviewees. Secondary data from literature and reports supplements the Analysis. Findings show a lack of on-site segregation and essential management, 35% of the debris was dumped and more than 5% of the debris was burned illegally. Joint Service Councils manage collection and disposal but have limited capacity and funding. Political fragmentation also complicates coordination. Significant barriers include inadequate policies, infrastructure, lack of private sector compliance, and socioeconomic pressures. Study proposes a strategic framework to address these challenges to establish a coordinated C&D waste governance system by 2027. Objectives focus on strengthening regulations, improving on-site practices, developing infrastructure networks, boosting reuse/recycling markets, and creating sustainable financing mechanisms. A phased implementation plan outlines priority actions, responsibilities, and timelines for stakeholders to transition the sector toward sustainability. The framework provides a roadmap to guide reforms and capacity building needed to manage C&D waste responsibly in the West Bank.
- ItemTHE IMPACT OF ENTERPRISE RESOURCE PLANNING (ERP) IMPLEMENTATION ON SUSTAINABILITY PERFORMANCE IN HEALTHCARE AND THE MEDIATOR EFFECT OF JCI(An-Najah National University, 2025-04-17) Abu Al Haj, Ebaa MaherThe integration of Enterprise Resource Planning (ERP) systems in healthcare organizations presents a significant opportunity to enhance operational efficiency and improve accreditation outcomes. However, the relationship between ERP implementation and sustainability performance, particularly through the lens of Joint Commission International (JCI) accreditation, remains underexplored. This study addresses this gap by investigating how various factors, such as clinical error reduction, operational productivity, data analytics, and resource optimization, mediate the effects of JCI accreditation on the relationship between ERP implementation and sustainability performance. To conduct this research, a sample of 53 administrative staff from two hospitals in Nablus and Jerusalem were surveyed for this research. This approach differs from most prior research, where subjects were normally professionals with long experience in management and technology fields. In this context, the research will employ a more diverse sample to enrich the understanding of ERP systems’ capabilities to support sustainability objectives in healthcare organizations. Data were analyzed using descriptive statistics to quantify and summarize key variables within the population. Statistical software was employed to conduct correlation and regression analyses, providing a robust framework for interpreting the relationships among variables, like SPSS , Smart PLS . The key findings indicate a statistically significant positive relationship between implementing ERP and getting JCI certification. This supports the hypothesis that ERP increases the likelihood of meeting JCI standards. However, contrary to the existing literature, our study found no significant influence of either ERP or JCI on sustainable performance. This suggests that organizations have problems aligning their ERP systems with sustainable objectives because of fragmented processes and scant integration into strategic goals. Based on these findings, it is recommended that healthcare organizations align their ERP systems with sustainability goals. This can be done by promoting better coordination between business units on strategic targets and encouraging staff to take part in sustainability ventures. Future studies need to follow up on these dynamics in more detail to discover how they can best influence overall healthcare practice towards sustainability.
- ItemTHE NEXUS BETWEEN GREEN HUMAN RESOURCE MANAGEMENT, GREEN INNOVATION, AND DIGITAL TRANSFORMATION TOWARDS SUSTAINABILITY IN THE PALESTINIAN MANUFACTURING SECTOR(An-Najah National University, 2025-01-08) Ali Ahmad, SajedaGreen human resource management is an important concept introduced and studied in recent decades due to the increasing interest in the environment and the pursuit of sustainability through protecting available natural resources and reducing the risks of environmentally harmful practices. Therefore, the level of implementation of these practices was evaluated in the manufacturing sector to achieve the desired goal of this study. The researcher proposed eighteen hypotheses and used the AMO, RBV, and TBL theories. A review of the relevant literature was conducted to enrich the research on the nature of GHRM and its relationship to different variables. Then, Comprehensive inventory method was used to collect data from specific manufacturing sectors by electronic questionaries , where 125 population size and 95 people responded to the questionnaire responded to the questionnaire, distributed between the general manager, executive manager, human resources manager, quality manager, production manager, and others. The Smart-PLS software was used to analyze the collected data. The results indicated that green human resource management practices positively impacted environmental performance. They do not influence social and economic performances. Moreover, green innovation completely mediated the relationship between the GHRM and social performance. On the other hand, digital transformation completely mediates the relationships between GHRM and economic performance and completely mediates the relationships between GHRM and social performance, partially mediates the relationship between GHRM and environmental performance. This study added empirical evidence and influenced the literature on GHRM issues in the manufacturing sector. The researcher recommends that the Palestinian manufacturing sector pay attention to environmental initiatives, in addition to supporting the senior management of factories for any environmental initiative and supporting green innovation and digital transformation, which contribute to sustainability in a very positive way. It is essential to raise awareness of environmental issues among employees, workers, and management.
- ItemRISK BASED MANAGEMENT OF INDUSTRIAL WASTEWATER IN NABLUS CITY(An-Najah National University, 2024-10-13) Afaneh, AteidIndustrial wastewater is highly polluting the environment if not handled properly, also affect the wastewater infrastructure for both collection and treatment. Most of consumed water is converted to wastewater from residential, industrial, and commercial uses. Industrial wastewater is a critical concern for all industrial settings that lacks the infrastructure to handle such water. Generally, industrial wastewater in Palestine represents a major challenge to the environment and municipal infrastructure, mainly in the industrial cities like Nablus city. This thesis aims at concluding the most appropriate solutions which prevent or decrease the hazards resulted from industrial wastewater on the wastewater infrastructure and its operation. The research utilized the risk based management approach to propose proactive and reactive barriers for industrial wastewater hazards and impacts. Cost Benefit Analysis was used to estimate the costs and benefits for Nablus municipality for each identified barrier. Risk analysis was carried out to explore the hazards and impacts of industrial wastewater on the infrastructure; Wastewater Network (WWN) in Nablus and Nablus- West Wastewater Treatment Plant (NW-WWTP). Risk evaluation was used to priories the hazards through the calculated risk priority number (or degree of severity) to quantify risk. Results showed that industrial wastewater, which had risk priority number of 9 poses a significant threat to the municipal infrastructure. Infrastructure damage and operational inefficiencies were resulted. To reach this thesis's goal, estimated proposed strategies to reduce negative impacts were discussed in risk control approach. After conducting risk cost benefit analysis for Nablus municipality, it is found that awareness and WWN rehabilitation have to be excluded because their proportion Factor (d) is more than 1, but the other barriers should be executed by the municipality. Since equipment insurance barrier has the smallest d which is 0.0036, it has to be prioritized. Then, to execute the remaining barriers from smallest d in ascending order. Finally, risk based management approach and risk cost benefit analysis options are very useful tools to mitigate and adapt hazards to improve the preparedness and response for Local Governmental Units (LGUs), particularly in the field of wastewater management. The results of this thesis should guide the implementation of effective management practices that ensure environmental protection and infrastructure resilience.
