1 Sustainable and resilience planning for the supply chain of online hyperlocal grocery services
برنامه ریزی پایدار و انعطاف پذیر برای زنجیره تأمین خدمات مواد غذایی آنلاین بیش از حد محلی-2021
In an uncertain Supply Chain (SC) environment dealing with suppliers and transport-level disruptions in addition to fulfilling customers’ requirements is a complex task. Such challenges are more taxing in case of perishable products SCs. The concurrent effect of all such events affects the economic stability of SC and impedes sustainability on a longer planning horizon. The proposed study presents a case example of e-commerce based SC addressing an operational and distribution planning problem. For this purpose, the study simulates online grocery business operations by proposing a mixed-integer linear programming problem to minimize SCs expected cost. It includes the costs of purchase, transportation, supply-demand mismatch, and cost of economic loss due to the perishable nature of the products. Computational analysis is performed to manifest the performance of the proposed model considering the dataset of a hyperlocal distribution service. The study evaluates the utility of resilience and sustainable strategies to minimize expected economic costs and reduce environmental impacts by effectively managing waste. A backup strategy is devised to promote a resilient SC planning to fight the risk of disruptions and operational failures. Additionally, economic sustainability is achieved by implementing various markdown policies and waste minimization strategies. A sensitivity analysis using MonteCarlo simulation is presented to recognize the impact of operational risk, demand uncertainty, and perishability on the expected cost. Majorly, it contributes to the scant literature of quantitative modeling for the production and distribution of food SC to promote resiliently sustainable planning. Further, the resilient and sustainable strategies, procurement policies, penalty assessment, and markdown due to perishability are some of the key contributions of the study. The discussion provides plenty of opportunities to pursue future studies in operational and distribution management of e-commerce SCs.

2 The Importance of the Social License to Operate at the Investment and Operations Stage of Coal Mining Projects: Application using a Decision Support System
اهمیت پروانه اجتماعی برای فعالیت در مرحله سرمایه گذاری و عملیات پروژه های استخراج زغال سنگ: درخواست با استفاده از سیستم پشتیبانی تصمیم-2020
The Social License to Operate (SLO) and the Value Chain business model are basic elements that need to be considered both at the planning and operation stages of mining operations and in particular in coal mining projects. If a coal mining enterprise loses its SLO, it may face risks in operations, which may lead to value chain risks. One of the causes of enterprise failure as related to coal mining operations is the inability to reliably assess/ manage risk holistically and the inability to understand that lack of SLO is a critical risk. Although financial risks are typically assessed for mining projects, lack of SLO risk should also be taken into account starting as early as the bankable feasibility study. Furthermore, as it is difficult to establish a proactive decision-making policy for SLO risk in coal mining operations, the Operational Risk Management (ORM) methodology is probably a good tool to apply towards that goal. For this reason, a Mining Operational Risk Management Model (MORMM) was developed to incorporate risk probabilities and risk severities evaluated by experts. The final risk assessment is coded using Risk Assessment Codes (RACs). A hypothetical scenario was developed utilizing the MORMM model in order to illustrate how risks can be managed during the SLO granting process. This scenario describes a hypothetical coal mining project evaluated by virtual risk evaluators under specific hazard categories. Risk evaluation involves the assessment of risk probability and risk severity. Through this scenario this paper presents ways: (i) to establish a baseline ORM process that will be applicable to any coal mining operation environment, and (ii) to provide a theoretical example to demonstrate how the method can be applied to coal mining operations. The resulting RACs can provide critical information to decision makers regarding the rejection, acceptance or re-engineering of the mining business plan.

3 Bank Risk Control based on FPGA and Machine Learning
کنترل ریسک بانکی بر اساس FPGA و یادگیری ماشین-2020
With the continuous increase of machine learning in business applications, it is being considered that many of the solutions are implemented. Due to the impact of the global financial crisis, the bank has achieved a more pro- nounced risk management, and risk, discovered measured, there was a continued interest in the reporting and management methods. In academia and industry, a lot of research, development banks and risk management, focuses on the current new challenges of. That what has been proposed is an analysis and evaluation of machine learning techniques that have been studied in the risk management of the bank, this is a completely on-site and risk management issues, and to determine. This will explore the potential areas for further research. The application, review risk management and machine learning centers, such credit risk, market risk, risk of learning machine of banking, such as liquidity risk has been shown to operational risk have been studied, It does not seem to be comparable to the level in the current industry. Many of the fields, in the ruins of machine learning, and risk management in the banking, you can benefit greatly from the study of methods that can be applied to solve a specific problem.

4 Business complexity and risk management: Evidence from operational risk events in U:S: bank holding companies
پیچیدگی تجارت و مدیریت ریسک: شواهدی از وقایع ریسک عملیاتی در شرکت های هلدینگ بانکی ایالات متحده-2020
Recent regulatory proposals tie a financial institution’s systemic importance to its complexity. However, little is known about how complexity affects banks’ risk management. Using the 1996–1999 deregulations of U.S. banks’ nonbanking activities as a natural experiment, we show that banks’ business complexity increases their operational risk. This result is driven by banks that had been constrained by regulations, compared with other banks and also with nonbank financial institutions that were never subject to these regulations. We provide evidence that managerial failure underlying these events offsets benefits of strategic risk taking.

5 The effects of sustainability practices on the performance of risk management and purchasing
تأثیرات عملکردهای پایداری بر عملکرد مدیریت ریسک و خرید-2020
Companies need special purchasing and supply management practices to ensure that their supply chains are sustainable and transparent. However, sustainability practices do not only serve the purpose of securing sustainability, but also help companies to avoid economic and reputational damage and risks. This paper studies the influence of sustainable purchasing practices on the risk management performance and purchasing performance by using quantitative survey data collected from 111 Finnish companies. The direct and indirect relationships between the concepts are examined using a partial least squares methodology. The results show that the use of sustainable purchasing practices improves the purchasing performance of businesses. Firms that invest in sustainability management in their purchasing will more likely have better performance in their purchasing and supply management. It was also found that sustainable purchasing practices improve reputational and operational risk management performance, which indicates that sustainability practices are significant in risk management in general, not only in relation to sustainability.© 2020 Elsevier Ltd.

7 Money, debit card, gross-settlement risk, and central banking
پول ، کارت بدهی ، ریسک تسویه ناخالص و بانکداری مرکزی-2019
A monetary model is constructed to explore the effects of a new source of inefficiency of gross settlement with an operational risk on the choice of cash that is risky to hold and a debit card that is costly to use. During inflation, gross settlement would entail the deposit of a larger amount of money as payments and collaterals for the finality of the settlement process, thereby leading to a consumption loss. The endogenous adjustment between gross and net settlement may alleviate this distortion from inflation. Hence, the optimal monetary policy is to decrease the money supply so as to minimize the cost of theft and transaction costs of a debit card usage.

8 Correlation between strategic and operational risk mitigation strategies in supply networks
همبستگی بین راهبردهای کاهش خطر عملیاتی در شبکه های تامین-2018
A supply networks performance is affected by two types of risk: 1) risk of disruptions that distort the supply networks topology by inactivating certain production facilities or transportation lanes; and 2) risk of variations in a facilitys performance that reduce the efficiency of the supply networks flow planning for fulfilling demands. In this paper, we demonstrate that strategic and operational risk mitigation strategies, which neutralize the impacts of disruptions and variations, respectively, are correlated. We consider “Robustness” and “Resilience” at a strategic level to mitigate disruptions and “Reliability” at an operational level to mitigate variations. A mixed integer stochastic mathematical model is developed to simultaneously a) design a robust and resilient topology for supply networks; and b) plan a reliable flow throughout its topology. We solve the model using an example of a profit-based supply network that is constructed by relying on the assumptions that were primarily used in prior studies. A sensitivity analysis of the results from the model indicates that i) the correlation between robustness and resilience is negative; ii) the correlation between robustness and reliability is positive; and iii) the correlation between resilience and reliability is negative.

9 Inventory component volatility and its relation to returns
فراریت مولفه انبارداری و رابطه آن با بازگشت ها-2018
Members of manufacturing supply chains have to take many risks. Prior academic work emphasizes that inventory management is one of the pivotal sources for operational risks, particularly in terms of inventory volatility and excess inventory. Recent research shows that total inventory volatility not only poses a threat to a firms operational performance, but also increases a firms abnormal stock returns. However, the volatility impact of the three underlying inventory components—raw materials, work-in-process, and finished goods—is still unresolved. We argue that the relationship between inventory volatility and stock returns differs between the three inventory components since they each relate to different stages of the supply chain. Using a sample of U.S. manufacturing firms over the period 2005 to 2013, we empirically examine the relationship between inventory component volatility and stock returns. We find a significant positive association between work-in-process inventory volatility and stock returns, a significant negative association between finished goods inventory volatility and stock returns, and no significant association between raw material inventory volatility and stock returns. In additional analyses, we find that types of industry dynamism influence these relationships. The results of this study provide a more detailed picture regarding the investor perception of inventory dynamics.

10 Impacts of geographic diversification on restaurant firms’ risk: Domestic vs: international diversification
اثرات تنوع جغرافیایی بر خطر شرکت های رستوران: داخلی در مقابل: تنوع بین المللی-2017
In the hospitality context, the diversification literature has evolved to mostly focus on the impact of diversification on firm performance. However, without accounting for risk, the effect of diversification on firm value likely provides an incomplete picture. Therefore, this study investigates the influence of domestic and international geographic diversification on restaurant firms’ risk. This study uses the Berry-Herfindahl Index to measure the degree of domestic and international geographic diversification. Findings show a non-linear relationship between geographic diversification and restaurant firms’ risk. However, different shapes of the non-linear relationship are revealed between domestic and interna tional geographic diversification and between operational and market-based risk. The results of this study indicate that the risk-reduction effects argued from the modern portfolio theory may be partially appli cable to the geographic diversification for restaurant firms, suggesting a different view toward financial diversification and corporate diversification.
Keywords: Geographic diversification | Domestic diversification | International diversification | Market-based risk | Operational risk
