We consider the stochastic demand of an inventory system with defective items and the weekly demand, according to the Poisson process. Our objective is to formulate a Markov decision model to minimize the total expected cost, which includes production, holding, defective, and shortage. Markov decision model is formulated to describe the stochastic demand. Also, we show two strategies for disposal of defective items; the first one at the end of the week, and the second one continues during the week. The production rate represents a function of inventory, which has limited capacity. The results show a decrease in the shortage cost and increase in the production rate, in the case of disposal of defective items continues during the week.We consider the stochastic demand of an inventory system with defective items and the weekly demand, according to the Poisson process.

Heart rate variability (HRV) provides information of cardiac autonomic control which indicates the interaction of sympathetic and parasympathetic nervous system. The purpose of this study was to investigate the effects of eight weeks traditional archery training on heart rate variability among sedentary lifestyle youth. Thirty-four inactive male (performed 0.05). In other hand, both groups showed non-significant difference on SDNN value after eight weeks of intervention (p > 0.05). However, the traditional archery group has showed an improvement of SDNN value meanwhile control group was declined. Eight weeks of traditional archery training programme was effective improving heart rate variability among sedentary lifestyle youth. Therefore, traditional archery could be proposed as one of the possible methods to combat poor cardiac autonomic function following sedentary lifestyle.Heart rate variability (HRV) provides information of cardiac autonomic control which indicates the interaction of sympathetic and parasympathetic nervous system.

Data Envelopment Analysis (DEA) model usually does not consider the interaction between the decision making units (DMU). The interaction can be represented in the form of two consecutive stages in which the outputs from the precedent stage will be the inputs for the latter stage. The two consecutive stage DEA model can be represented as Non-separable DEA (NS-DEA) which integrates both desirable and undesirable output. The undesirable output unlike desirable output, indicates a higher efficiency if the output is lower or not productive. The different orientation between desirable and undesirable output may affect the efficiency score especially if it was formed in two consecutive stages. Thus, this research attempts to address four different types of dependence relationship which can occur in the formation of two consecutive stage DEA models and to investigate the impact towards the overall efficiency of the DMUs. The finding shows that the determination of positive or negative correlation between the two stages which combines both desirable and undesirable output, are more likely to be influenced by the orientation of the first precedent stage.Data Envelopment Analysis (DEA) model usually does not consider the interaction between the decision making units (DMU).

Despite minimal exchange rate exposure previously found in developed region, comprehensive study on the level of exchange rate exposure in a small open economy such as Malaysia remains scarce. Additionally, ignoring the direction of currency movement inflicts bias in estimation due to the commingling of positive and negative exposure. Hence, this paper examines the symmetric and asymmetric exchange rate exposure of 207 Malaysian non-financial firms at both aggregate and firm levels. Employing data from 1995 to 2016, the panel analysis found significant aggregate stock returns exposure to changes in the USD, mainly due to the strong US position as Malaysia’s major trading partner. Next, the firm-level analysis involving regression with GARCH(1,1) specification concludes that 35.75% of our sample firms are affected by the symmetric exposure. The higher exposure of Malaysia sample firms relative to western economies reflects the lack of hedging exercises and considerably moderate growth of derivatives market in Malaysia. In term of asymmetric exposure, there are large proportions of firms significantly affected by the USD appreciation. Inclusion of five sub-periods comprising two financial crises and pegging regime into the analyses indicates different significance levels throughout the periods. The detailed results of the study offer better insights for firm manager in making strategic decisions towards effective currency exposure management.

The issue of whether Malaysians are adequately prepared for costs of their future retirements has been the subject of significant debate and research over the last few years, especially for those who contributing under defined contribution (DC) plan, since the contributors under this plan are allowed in managing some portion of their savings. The contributors are allowed to withdraw or invest during contribution (working) period, according to rules and regulations. Therefore, the objective of this study is to estimate the retirement wealth adequacy of future retirees under the DC plan in Malaysia using wealth-need ratio model and simulation approach. There are four simulated wealth-need ratio models projecting with several feasible scenarios, including an optimistic scenario involving more investment activities (more-investments) and a pessimistic scenario including no or less investment activities (more-savings), based on several related assumptions. The results show that 43% of households are projected to have adequate retirement benefits under the pessimistic scenario, while 94% of households are projected to have adequate retirement benefits under the optimistic scenario. In addition, three hybrid models are constructed to provide more realistic scenarios of Malaysian population, by developing three samples with different proportions of households with more-investments, and households with more-savings. The results show that 80% of households with higher proportion of more-investments households have adequate retirement benefits, while only 65% of households with higher proportion of more-savings households have adequate retirement benefits.The issue of whether Malaysians are adequately prepared for costs of their future retirements has been the subject of significant debate and research over the last few years, especially for those who contributing under defined contribution (DC) plan, since the contributors under this plan are allowed in managing some portion of their savings.

After the Subprime crisis 2008, the issue of loan default has gained significant importance by regulators, bankers, academia as well as market players around the globe till today. So far, large volume of studies have been devoted in investigating several bank characteristics affecting credit risk, however lack focus has been put to specifically examine the impact of capital thresholds on credit risk level. The issue on how well capitalized banks perform in relation to non-performing loan remains unresolved especially for small developing market of Malaysia. Motivated from here, the purpose of this study is to investigate the impact of capital on non-performing loan problem under different capital thresholds from March 2010 till September 2017. Using non-dynamic panel threshold model, the study finds that capital threshold is significant in affecting the relationship between credit risk and capital level. Furthermore, there is negative relationship between capital and credit risk under large capital regime, suggesting that well-capitalized banks are having adequate resources and expertise, reflecting better risk management and improved governance in minimizing defaults.After the Subprime crisis 2008, the issue of loan default has gained significant importance by regulators, bankers, academia as well as market players around the globe till today.

This project is focused on existing of chaos in stock market price. Stock market price is frequently changing in a particular time period. The pattern of stock market price is hard to predict as it is complex and exhibit nonlinear behavior. Due to insufficient chaotic findings for local company in Malaysia, existence of chaos in stock market price of Gamuda Berhad is determined in this project. There are two tests involved in this project which BDS Test and Close Returns Test are mainly used in this project for examining chaos in the stock market price. As for the result, BDS Test results show the rejection of the null hypothesis which means stock market price of Gamuda Berhad is not independent and identically distributed (IID) and Close Returns Test shows the non-chaotic behavior for the data. Therefore, the stock market price of Gamuda Berhad has non-chaotic nonlinearity behavior.This project is focused on existing of chaos in stock market price.

本课题主要研究股票市场价格存在的混乱现象。股票市场价格在特定时期内经常变化。股票市场价格模式复杂且表现出非线性特征，难以预测。由于对马来西亚本地公司的混沌研究不足，本项目确定了甘慕达股份公司股票市场价格存在混沌。本项目涉及两个测试，其中BDS测试和Close Returns测试在本项目中主要用于检查股票市场价格的混乱。对于结果，BDS检验结果表明原假设被拒绝，即Gamuda Berhad的股票市场价格不是独立同分布(IID)， Close Returns检验表明数据具有非混沌行为。因此，Gamuda Berhad的股票市场价格具有非混沌非线性行为。本课题主要研究股票市场价格存在的混乱现象。股票市场价格在特定时期内经常变化。股票市场价格模式复杂且表现出非线性特征，难以预测。由于对马来西亚本地公司的混沌研究不足，本项目确定了甘慕达股份公司股票市场价格存在混沌。本项目涉及两个测试，其中BDS测试和Close Returns测试在本项目中主要用于检查股票市场价格的混乱。对于结果，BDS检验结果表明原假设被拒绝，即Gamuda Berhad的股票市场价格不是独立同分布(IID)， Close Returns检验表明数据具有非混沌行为。因此，Gamuda Berhad的股票市场价格具有非混沌非线性行为。

A Cournot duopoly is a market dominated by two firms with profit maximization as their goal. An alternative to the profit maximization model is the constraint profit maximization model, where firms maximize their profits subject to minimum sales constraints. In this paper, a duopoly model with isoelastic demand function and homogeneous product is considered. The local stability condition of the Cournot equilibrium in the cases of sales constraint and no sales constraint were obtained. Initial results implied that it is easier for the duopoly model to be stable if firms impose some minimum constraints on their sales.A Cournot duopoly is a market dominated by two firms with profit maximization as their goal.
