    The present research aimed to design an agent-based simulation model of the service supply chain. In this respect, library studies were first conducted, and then the research gap was found. Suppliers were divided into suppliers of fast-moving consumer goods and slow-moving consumer goods, repairmen, and medicine suppliers, while services were divided into general, emergency, specialized, and nursing services, and patients were divided into people with insurance and those without insurance. Also, conditions of the service supply chain in this hospital were investigated and analyzed from different aspects. Next, this supply chain was implemented using NetLogo software, and the amount of unfulfilled demand and other cases were checked, and various weaknesses and gaps were shown. In the following, it was tried to decrease the existing gaps by developing different scenarios. Although the results of all the scenarios showed improved conditions, apparently, fast-moving consumer goods are the least affected by the decreased demand gap compared to the developed scenarios. In the maintenance section, the cost of preventive and in fact its increase can have the greatest effect. Regarding the increase of people covered by health insurance, the increase of insured people is a better scenario than reducing the treatment costs, and in fact, the reduction in treatment costs increase the number of people covered by health care services as it should.

    Portfolio optimization is a widely studied problem in financial engineering literature. Its objective is to effectively distribute capital among different assets to maximize returns and minimize the risk of losing capital. Although portfolio optimization has been extensively investigated, there has been limited focus on optimizing portfolios consisting of cryptocurrencies, which are rapidly growing and emerging markets. The cryptocurrency market has demonstrated significant growth over the past two decades, offering potential profits but also presenting heightened risks compared to traditional financial markets. This situation creates challenges in constructing portfolios, necessitating the development of new and improved risk management models for cryptocurrency funds. This paper utilizes a new risk measurement approach called Conditional Drawdown at Risk (CDaR) in constructing portfolios within high-risk financial markets. Traditionally, portfolio optimization has been approached under certain conditions, considering risk and profit as decision criteria. However, recent approaches have addressed uncertainty in the decision-making process. To contribute to the advancement of scientific knowledge in this field, this paper proposes a new mathematical formulation of CDaR based on a chance-constrained programming (CCP) approach for portfolio optimization. To demonstrate the effectiveness of the proposed model, a practical empirical case study is conducted using real-world market data from 10 months focused on cryptocurrencies. The results obtained from this model can provide valuable guidance in making investment decisions in high-risk financial markets.

    One of the constant problems that people with mental health conditions are faced with now is that they cannot establish a good relationship with their therapist, or the client's disease type is not in the therapist's specialty. These clients may not receive adequate treatment and stop the therapy before feeling well. Therefore, the classification of mental patients based on their disorder types and allocating a therapist with the same expertise to them could lead to better treatment and improve the quality of the therapy sessions. This paper will compare several machine learning (ML) algorithms to classify patients with mental conditions. Moreover, benefiting from the best ML algorithm, patients will be categorized into different classes based on their disorder types. Finally, a mathematical model will be developed to determine the allocation policy of therapists to each group of patients to maximize the summation of the utilization between therapists and patients. To explore the implementation of the proposed method, we have conducted a real-life case study to assess the validation of the model.

    Liquefaction of soil exposes buildings, bridges, and other vital infrastructure to structural failure, subsidence, and loss of bearing capacity during earthquakes. It can endanger safety and result in significant financial losses in seismically active areas. The objective of the present study is to identify the key factors influencing soil liquefaction is essential to improving the precision of risk assessment and mitigation plans in seismically active regions. An abrupt increase in pore water pressure leads to a significant fall in effective stress, which in turn causes a significant drop in shear strength. Soil liquefies, losing its ability to bear shear stresses and behaves as a fluid. To identify the key factors influencing soil liquefaction, an integrated Multi-Criteria Decision Making (MCDM) technique FUCOM-SVNN TOPSIS (Full Consistency Method (FUCOM), Single Valued Neutrosophic Number (SVNN), and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)) has been developed. The study meticulously selects three key criteria and nine alternatives influenced by extensive literature review. Employing the FUCOM for establishing weights of criteria. FUCOM indicates that 'Seismic' is the most significant criteria. SVNN-TOPSIS applied for degerming the rank of alternatives. The results of SVNN-TOPSIS indicate that 'Peak Ground Acceleration' plays the crucial role in determining liquefaction potential. Validation of the proposed model by comparative study, statistical and sensitivity analysis, this methodology addresses the inherent uncertainties and interdependencies among various parameters, thereby enhancing the decision-making process related to seismic hazards.
