Construction's problems are the weakness of construction project and always being worried by the construction practitioners as it might bring failure to their project. Many have acknowledged that buildability implementation is an effective way to minimize these problems. This study focused on the buildabilty problems and its root causes that arisen in the Malaysian building construction, by conducting literature review and document study on various construction sites throughout the country. The results confirmed that there are fourteen types of buildability problems that occurred in the Malaysian building construction. Buildability problem related to utilities, right of way and drainage pattern has the highest occurrency while buildability problem related to traffic control requirement has the lowest occurency. Meanwhile, there are ten identified root causes to buildability problems with the most frequent root cause is lack of design review (C6) and the least frequent is design with time constraint (C5). This study has successfully identified the buildabilty problems and its root causes where the findings served as guide for future buildable design.

In manufacturing industry, engineering drawing is used to facilitate the process of designing a product. In real situation, the engineering drawing is usually available in a large quantity and not in order. This is due to many drawings are produced in the process of designing a product. Effective access of engineering drawings from various numbers of engineering drawings is very challenging. Engineer can reduce the cost of designing a new product by retrieving the original drawings of components from the database in the CAD software. This paper presents a review on extraction of non-geometry information in engineering drawing. It explores the past studies on the existing extraction methods discovered by numerous researchers in the field of engineering drawing. In this research, the information that will be extracted is non-geometry information such as length, thickness, radius, diameter and labels. The comparative example of extraction in engineering drawing of previous research has been carried out.

This paper describes the application of simulation in designing and improving the manufacturing system. Simulation is a useful tool when analyzing complex manufacturing systems to help sort through cause-and effect relationships and gain a better understanding of what is actually causing a particular problem in the system. Once cause-and-effect relationships are identified, changes for improvement can be made more intelligently. Simulation is used to model and analyze the behavior of the real system, can answer “what if” types of questions about the real system, and aid in the modeling the improvement of the real system. This study presents the use of simulation modeling in the Voice Coil Motor (VCM) and general application magnet capacity process flow at XYZ factory. The simulation model was built using ARENA® software. The model experiment by using what-if analysis was performed to select what characteristics to be the best for the system. The results from this study are expected to help operation management division to improve the system performance in order to increase the factory's production.

Pharmaceutical product recalls (PRs) have become rampant and increased dramatically in recent years. Decision for PR is made if there is or may be risk to the user of the product due to faulty production or medical reasons. This retrospective study was to evaluate the pattern and trend of PR incidence and to identify the major manufacturing and clinical root causes of reported pharmaceutical product (i.e. drug) recalls in one of the big and busy tertiary care public hospitals located in Klang Valley, Malaysia. Data in PR forms between January 2003 and December 2009 were recorded and analysed descriptively. Overall in 7 consecutive years, the study hospital received 74 general nation PR notices (2003: n = 17 (23.0%); 2004: 14 (18.9%); 2005: 12 (16.2%); 2006: 3 (4.1%); 2007: 5 (6.8%); 2008: 16 (21.6%); 2009: 7 (9.4%)). About 27 (36.5%) of direct PR notices involved this hospital merely. National Pharmaceutical Control Bureau issued 6.8% PR notices, pharmaceutical companies voluntary 91.9% and 1.3% unstated. Pharmaniaga Manufacturing requested PR the highest (16.2%), followed by Safire Pharmaceuticals (13.5%), Duopharma (12.2%) and SM Pharmaceuticals (12.2%). Degree III was the commonest action level of nation PR (97.3%) compared to degree I (2.7%). Among the reasons of PR include pharmaceutical physical appearance (40.5%), physicochemical parameter (28.4%), adverse drug reaction (4.1%), microbial test (4.1%), packaging (4.1%), contamination of foreign particles (2.7%), mixed up with other ingredients (2.7%) and sterility (1.3%). The highest pharmacological class of PR was antibiotic (14.9%), followed by non-steroidal anti-inflammatory drugs (NSAIDs) (9.5%), vitamins (8.1%) as well as antifungal (8.1%). The most respective frequent dosage form was tablet (51.4%), followed by injection (14.9%) and suspension (12.2%). The response periods toward PR were 39.2% < 7 days, 37.8% > 7 days – 1 month and 16.2% > 1 month. Essential actions taken by all respective parties in dealing with the specification of the pharmaceutical products to ensure drug safety and harmless drug use hence avert possible health risks to patients.

This paper examines the briefing process of construction projects where the two fundamental requisites are identification of clients' requirements and translating them into building form. The attributes of the client as the key project participant during briefing is vital to ensure the preparation of accurate briefs. The client attributes investigated were categorized into three; the quality of the client representatives, brief management efforts and commitment of client organization. The influence of client attributes on the level of project success was analyzed. It is concluded that strong leadership, knowledge on both organization mission and construction process and commitment are the essential client qualities for ensuring effective briefing as well as project success.

As part of structural reliability assessment, the statistical analysis provides engineers with good estimation of distribution and statistical properties for both load and resistance. This study involved modelling of eight (8) offshore structures with the corresponding environmental conditions for ten (10), fifty (50) and hundred (100) years in order to perform non-linear push over analysis for getting the ultimate strength. The environmental condition covers three main oil and gas regions in Malaysia. The collective results of base shear and collapse capacity were used for statistical analysis. The data were analyzed using probability density function with central limit theorem under Gaussian distribution. All the statistical parameters such as mean value (μ), standard deviation (σ) and variance (V) were calculated. The average base shear from the statistical analysis has been obtained as 3.03 MN with a standard deviation of 3.35 and variance of 11.26. For the resistance part, the mean collapse capacity has been obtained as 18.28 MN with a standard deviation of 18.10 and variance of 327.93. This meant that for general case, the structural resistance is higher than the environmental loading. Using probability density function, the reliability index (β) was estimated through robust calculation between statistical parameters of load and resistance. From this calculation, reliability index (β) has been estimated as 3.97.

Factors that should be taken into consideration during the economic evaluation of the building have a direct impact on the total project cost. Literature reviews on construction cost factors reveal that researches in this area have been conducted in various parts of the world decades ago. Nevertheless, none of these studies has substantively estimated the causal relations among the construction cost factors. As a result, this paper presents a research proposal to evaluate and model construction cost factors particularly in the Klang Valley area of Malaysia by using the structural equation modeling approach. The resulting construction cost factors models will be validated in terms of convergent and discriminant validity, construct reliability, and goodness of fit.

Nowadays, consumers expect manufacturers to provide excellent quality, reliable delivery and competitive pricing. This demands that the manufacturer's machines and processes are highly reliable. In order to possess highly reliable machines to make sure smooth manufacturing process, many organizations have implemented Total Productive Maintenance (TPM) as the enabling tool to maximize the effectiveness of equipment by setting and maintaining the optimum relationship between people and their machines. Overall Equipment Effectiveness (OEE) is used as a measure when evaluating the result of TPM. This paper intends to find out the difference between before and after the TPM implementation to OEE result. Comparison between before and after the implementation of TPM is carried out to see the difference that TPM can bring to an organization. Elements that constitute the OEE equation will be analyzed in order to identify which one that affects OEE result. After identifying, improvement will be made on that element so that OEE result will be improved ultimately. The approach used in this paper is experimental and the instruments used to collect data are observation and interview. Microsoft Excel is used to analyze data obtained and calculate OEE. Hence, TPM is a useful tool in helping firm to achieve optimal manufacturing process. By being able to achieve this level of maintenance, an organization will be able to reap competitive advantages brought by TPM, thus, producing quality products that manage to satisfy customers and subsequently generating greater profits.

This study investigates the long-run and short-run movements of two emerging stock market volatilities using a volatility decomposition methodology. We studied the impact of 2007–2008 subprime mortgage crisis on the transitory and permanent volatility components in terms of two empirical stylized facts, the leverage effect and volatility persistence. In order to do so, the long spanning data are separated into three different periods. For the former stylized fact, the crisis impact on the leverage effect is mainly temporary with no long-run effect to the stock markets. This finding explains that the leverage effect is mostly difficult to adjust in the short-run transitory volatility during the crisis periods. However with proper risk management and long term strategies, most of the market participants are able to anticipate and handle this news impact in the long-run. For the latter stylized fact, the crisis has slightly increased the volatility persistence in all the markets. From the viewpoint of heterogeneous market hypothesis, the higher intensity of volatility persistence implies the stock markets are less informational efficient.
