Inventory risk based technique for spare parts utilization

The equipment breakdown due to unavailability of spare parts has incurred challenges for the manufacturing industry in managing the inventory. Consequently, the problem of spare parts unavailability has lead the organization towards unproductive and eventually impact the financial performance.Therefore, maintaining good system has direct connection with spare parts availability. The inventory planner always strive hard to ensure that the spare parts are always available for the maintenance used.Nevertheless, maintaining high inventories of spare parts often conflict from meeting the needs of equipment reliability for the manufacturing plant.In view of this situation, management of spare parts become critical in ensuring the equipment reliability.This paper describes an innovative risk quantification technique using Binary Decision Diagram (BDD) for the spare parts inventory control.The technique modified the BDD concept by translating the failure history into binary decision.From the binary process, the data will be converted into spare parts probability table and failure impact is analyzed. These two functions of risk, will be calculated in order gain the risk in monetary value

A hybrid simulation approach in developing a risk quantification model for coal procurement in power generation

All energy systems provide some level of security to its consumers.However, the right or optimum level of security is very difficult to assess. In order to make a comparison between the cost of providing energy security and level of security, the quantified risks have to be in the common accounting platform of cost.Then, an optimum level of security and cost can be estimated using appropriate methods.Since no such attempts have been done to compare the risks and the cost in the same platform, i.e. monetary unit, it is unpractical to determine the optimum point between the risks and cost of providing security in any energy systems.The objective of this paper is to present a new hybrid simulation model in risk analysis which computes the total exposure of coal procurement in power generation through the summation of quantified supply shortage risk in monetary terms and the cost of coal procurement. The hybrid simulation model is made up of two main components: 1) Dynamic Risk Calculation Program (DR-P) which was developed in System Dynamics platform for capturing the effect of dynamics behavior of price toward coal procurement risk, and 2) Non-delivery Probability Table Program (NdPT-P) which was developed in Matlab platform for computing all possible shortage level and the probability of shortage in selected coal procurement portfolio.The result from this paper has shown that the risks of coal procurement were increased as the cost of coal procurement were decreased and vice versa.However, the summation of risk and cost which give the total exposure of coal procurement has provided more accurate information for selecting the best coal procurement portfolio option

Supply Chain Management Model of Wood Biomass Producing Hydrogen Fuel for Malaysia’s Electricity Industry

Green energy is becoming an important aspect of every country in the world toward energy security by reducing dependence on fossil fuel import and enhancing better life quality by living in the healthy environment. This article analyses available literature as approach toward determining physical flows characteristic of waste wood biomass in high scale plantation toward producing gas fuel for electricity using gasification technique. The aim of this study is to develop a conceptual supply chain management model of syngas fuel from wood waste biomass using direct gasification conversion technology. Literature review on energy security, Malaysias energy mix, Biomass supply chain management and processing technology. This paper uses the theoretical model of transportation (Lumsden, 2006) and the function of the terminal (Hulten, 1997) for research purpose. The theoretical framework used to answer the research questions are Supply Chain Operations Reference (SCOR) framework and Sustainable strategy development in supply chain management framework. To incorporate biomass unique properties, Biomass Element Life Cycle Analysis (BELCA) which is a novel technique develop used to understand the behaviour of biomass supply based on biomasss elements

Routing Model of Oil Palm Fibre Waste toward Gas Fuel Production Supply Chain Management: Malaysia Industry

Green energy is becoming an important aspect for developed countries in the world toward energy security by reducing dependence on fuel import and enhancing better life quality by living in sustainable healthy environment. Issues regarding renewable energy production are source sustainability and reliability to ensure continuous production. Palm oil operation produces 80% varies type of waste and 20% oil palm products. Different range of physical and chemical of palm oil waste properties request different particular treatment and conversion energy method to optimize the desired bio product. Aim of this paper is to suggest the best Routing Model of Palm Oil Fibre Waste toward Gas Fuel Production Supply Chain Management based on evaluation of current Malaysias palm oil industry, practices in palm oil waste treatment and available energy conversation technologies. The framework is based on palm oil mill operation to utilise annually solid waste generated as source for stable annual biogas electricity production for grid. This paper highlight framework for the prospective researchers as well as practitioners to do further research to optimizes utilisation of palm oil waste for electricity production

Relationship between green information technology practices and attitudes of student in School of Technology Management and Logistics, Universiti Utara Malaysia

Green Information Technology is a study and practices of environmentally sustainable Information Technology.The lack practice of green information technology is the one issues of green information technology.When Information Technology sector growing rapidly become a problem of increasing energy waste, paper waste and electronic waste.For this research will be focused on the relationship between green information technology practices and student’s attitudes. This research to evaluate the practices of green information technology and to analyse the student’s attitudes of the practices of green information technology.Then to determine the relationship between green information technology practices and student’s attitudes. After that to encourage the green information technology practices.This study used questionnaire survey to collect data from Universiti Utara Malaysia students. Using statistics to analyse the correlation and regression analysis, there is a positive relationship between green information technology practices and student’s attitudes. In general, it can be concluded that students should be aware and practices of green information technology, but must practices on good behaviour. With the aim of getting more accurate result, except collect data from students, also should be collect data from other people in society

The respondents involved 340 students from STML. This questionnaire was analyzed by using multiple choice and Likert-Scale. Data was analyzed using IBM SPSS Statistic

Decision Making of Spare Parts Inventory Based on Risk Quantification

Financial losses due to spare part breakdown in plant operation have created an upsetting situation among stakeholders. The failure increase the cost of repair and production downtime. . Obviously, maintenance planner tends to increase the spare part inventory level in order to meet the operational requirement and this in return has increased the inventory cost. The maintenance and inventory function is important in order to ensure the plant operate accordingly. Moreover, it is necessary for the plant maintenance to balance the issue of shortage and excess of inventory in plant maintenance. In view of this situation, the spare parts become a critical matters and it is good starting point to tackle the issues from looking at the perspective of spare parts inventory risk. This paper explain about the development of risk based technique using the shortage and excess situation of spare parts inventory by using the Breakdown Probability Table to quantify the risk for decision making purpose
