Determining 2n values of fuzzy measure prior to applying Choquet integral normally turns into a complex undertaking, especially when the decision problem entails a large number of evaluation attributes, n. Many patterns of fuzzy measure have thus been suggested to deal with this complexity. λ0-measure is one such pattern. However, the original λ0-measure identification method was found to be unsuccessful in providing clear-cut indications on the relationships held by the attributes. A revised version of the method was then introduced to tackle this issue, but unfortunately it requires a large amount of initial data from the respondents compared to the original method. This paper therefore proposes an alternate version of λ0-measure identification method that synchronously compensates the shortcomings associated with each existing method. The proposed method uses interpretive structural modelling (ISM) to uncover the actual relationships held by the attributes. The outputs of ISM (i.e. digraph, driving power and dependence power) are then utilised to determine the inputs required to identify the complete set of λ0-measure values. A supplier selection problem was used to demonstrate the feasibility of the method. Also, the usability of the method was compared over the existing ones.

This paper investigates the impact of CSR disclosure and CEO integrity on earnings management. Analyzing a dataset of 750 firm-year observations of 150 Vietnam listed firms during the period from 2014 to 2018, the paper shows a significant positive effect of CSR disclosure on earnings management and a significantly negative impact on the CEO integrity on earnings management. The result confirms the previous studies that companies with more CSR disclosure are likely to engage in earnings management through increasing discretionary accruals. This suggests that managers may use CSR reporting to camouflage their earnings-management activities. Furthermore, the findings add to the literature of determinants of earnings management by offering an insight into CEO integrity and come to the proposal of enhancing the CEO role to control the earnings activities.

This paper introduces a new bi-objective vehicle routing problem that integrates the Open Location Routing Problem (OLRP), recently presented in the literature, coupled with the growing need for fuel consumption minimization, named Green OLRP (G-OLRP). Open routing problems (ORP) are known to be NP-hard problems, in which vehicles start from the set of existing depots and are not required to return to the starting depot after completing their service. The OLRP is a strategic-level problem involving the selection of one or many depots from a set of candidate locations and the planning of delivery radial routes from the selected depots to a set of customers. The concept of radial paths allows us to use a set of constraints focused on maintaining the radiality condition of the paths, which significantly simplifies the set of constraints associated with the connectivity and capacity requirements and provides a suitable alternative when compared with the elimination problem of sub-tours traditionally addressed in the literature. The emphasis in the paper will be placed on modeling rather than solution methods. The model proposed is formulated as a bi-objective problem, considering the minimization of operational costs and the minimization of environmental effects, and it is solved by using the epsilon constraint technique. The results illustrate that the proposed model is able to generate a set of trade-off solutions leading to interesting conclusions about the relationship between operational costs and environmental impact.

Over the last two decades, the global financial landscape has changed dramatically, including the corporate and political climates, the creation of more market-based economies, and rapid technological advancements. Micro, Small, and Medium Enterprises (MSMEs) is one form of market-based economies created with the most significant business opportunities and very important socially and economically in developing countries for many reasons. However, MSMEs face significant difficulty related to financial reporting standards to evaluate the achievement of business activities. Most MSMEs use a simple form for financial reporting, such as by calculating the difference between inflow and outflow from their business activities. Also, numerous previous studies that focus on Financial Accounting Standards in Indonesia are still limited. Thus, the present study investigates the factors that influence the implementation of Financial Accounting Standards (FAS) of Micro, Small, and Medium Enterprises (MSMEs) in Aceh Province, Indonesia. This quantitative study uses cross-sectional data collected by distributing 200 questionnaires to MSMEs actors that spread North Aceh Regency, namely Lhokseumawe city and Bireuen regency. The data are analyzed using descriptive statistics (e.g., frequency, percentage, mean, standard deviation) and inferential statistic (multiple linear regression) analyses. The study indicated that Perception, Education, Socialization and Incentive factors had significant positive effects on implementing Financial Accounting Standards of Micro, Small, and Medium Enterprises (MSMEs) in Aceh Province, Indonesia. In conclusion, this study has successfully investigated the factors that influence the implementation of Financial Accounting Standards of Micro, Small, and Medium Enterprises (MSMEs) in Aceh Province.

This study aimed to determine the impact of liquidity risk on financial performance of Jordanian banks, where liquidity risk was measured by (Liquidity ratio, net working capital, cash and investment ratio to total deposits), and financial performance was also measured through the index (return on assets) and the modifying variable (bank size) measured through the natural logarithm of total assets was also added. To achieve the objectives of the study, the analytical quantitative approach was adopted. The study community consisted of all 13 commercial banks listed on the Amman Stock Exchange. All banks in the study community were selected as a study sample using the comprehensive survey method, and the statistical analysis program (SPSS) was used to test the study hypotheses. Based on the results of the statistical analysis, it was found that there was an impact of liquidity risk on financial performance measured by return on assets in Jordanian commercial banks listed on Amman Stock Exchange, and there was an impact for each of (current liquidity ratio, net working capital, cash and investment ratio to total deposits) on financial performance measured by return on assets in Jordanian commercial banks listed on Amman Stock Exchange. It was also found that the size of the bank contributes to modifying the effect of liquidity risk on financial performance measured by return on assets in Jordanian commercial banks listed on Amman Stock Exchange. The study concluded a set of recommendations, the most important of which are: commercial bank administrations should increase interest in exploiting their liquidity within acceptable risk limits to reach optimal ratios for financial performance by balancing the returns to be achieved with the potential risks of such expenses in a way that ensures the positive impact of liquidity risk on the financial performance of those banks.

In a continuous manufacturing environment where production and consumption occur simultaneously, one of the biggest challenges is the efficient management of production and inventory system. In order to manage the integrated production inventory system economically it is necessary to identify the optimal production time and the optimal production reorder point that either maximize the profit or minimize the cost. In addition, during production the process has to go through some natural phenomena like random breakdown of machine, deterioration of product over time, uncertainty in repair time that eventually create the possibility of shortage. In this situation, efficient management of inventory & production is crucial. This paper addresses the situation where a perishable (deteriorated) product is manufactured and consumed simultaneously, the demand of this product is stable over the time, machine that produce the product also face random failure and the time to repair this machine is also uncertain. In order to describe this scenario more appropriately, the continuously reviewed Economic Production Quantity (EPQ) model is considered in this research work. The main goal is to identify the optimal production uptime and the production reorder point that ultimately minimize the expected value of total cost consisting of machine setup, deterioration, inventory holding, shortage and corrective maintenance cost.

The current pandemic era has given uncertainty to the country's economic growth and resulted in many countries experiencing a drastic decline in share prices. This condition impacts investors' perceptions of the funds that have invested in the stock market. This study investigates the effect of essential information and disposition effect on shifting decision investment with the character investor's moderation as the moderator variable. A survey was conducted on 252 investors who have invested in the Indonesian stock exchange. The Data processing used the partial least square (PLS) technique. This study indicates that essential information for investors in the pandemic era can increase the disposition effect in deciding beneficial share ownership. The essential information obtained by investors in the covid era regarding stock market movements and its internal performance in the stock market list can increase investor shifting decisions. The disposition effect can have a significant effect on shifting decision investors. Essential information related to stock price movements and its internal performance affects investors' courage to take risks and provide optimism for shifting decisions. Then the investor type does not affect the disposition effect on shifting decisions. This study contributes to the theory of financial behavior in decision making by considering psychological factors when uncertainty exists in the stock market.

This study aims to examine the impact of minority investor protection mechanisms on agency costs. All relevant indicators of minority investor protection adapted from the World Bank’s annual ‘Doing Business’ reports, along with concentrated government ownership, are employed with a panel data sample of 135 Vietnamese listed firms during the period 2014–2018. It is found that the following mechanisms are effective in mitigating agency costs and hence agency problems at the firm level: 1) review and approval requirements for related-party transactions; 2) minority shareholders’ ability to sue and hold directors liable for their duties; 3) minority shareholders’ access to internal corporate documents; 4) investors’ rights to approve major corporate investment and sale of asset decisions; and 5) disclosure in annual reports of salaries, bonuses and other forms of remuneration to directors and management. Interestingly, board independence and controlling government shareholders are not confirmed to play significant roles in addressing agency problems. To the best of the authors’ knowledge, this is the first attempt at testing for the impact of minority investor protection mechanisms developed by the World Bank on agency costs at the firm level, hence providing empirical evidence for the adoption of the minority investor protection mechanisms promoted by the World Bank. This study also provides policy implications for selecting effective mechanisms to mitigate agency conflicts between controlling shareholders and minority investors in order to enhance the financial performance of firms in an Asian emerging market.

The product-mix planning and the lot size decisions are some of the most fundamental research themes for the operations research community. The fact that markets have become more unpredictable has increaed the importance of these issues, rapidly. Currently, directors need to work with product-mix planning and lot size decision models by introducing stochastic variables related to the demands, lead times, etc. However, some real mathematical models involving stochastic variables are not capable of obtaining good solutions within short commuting times. Several heuristics and metaheuristics have been developed to deal with lot decisions problems, in order to obtain high quality results within short commuting times. Nevertheless, the search for an efficient model by considering product mix and deal size with stochastic demand is a prominent research area. This paper aims to develop a general model for the product-mix, and lot size decision within a stochastic demand environment, by introducing the Economic Value Added (EVA) as the objective function of a product portfolio selection. The proposed stochastic model has been solved by using a Sample Average Approximation (SAA) scheme. The proposed model obtains high quality results within acceptable computing times.

This research is conducted to examine the determinants of customer satisfaction in using debit cards issued by the Vietnam commercial banks (CB). By applying the exploratory factor analysis (EFA), logistic regression and linear regression on a dataset of 428 customers, we find that the features and price of products were the key determinants influencing the frequency of using debit cards. However, the impact of each determinant is heterogeneous among different groups of customers. Product price and features are more likely to influence the users using debit cards to purchase goods or services in stores or online than customers working for the public agencies or frequently using non-cash payment for high-valued transaction.
