Purpose: This article seeks to establish a statistical analysis to estimate the time of stoppages in a stamping line, which have a high variability that generates an unreliable scenario for the production program. Likewise, this document shows the methodological sequence to carry out a statistical analysis in a case study at an industrial level, considering variables of a real scenario.Design/methodology/approach: The methodological sequence is divided into five stages. Initially, the information of the stamping process was collected, later the types of stoppage were categorized according to the characteristics of the process. A collection of historical data information on stoppage times was carried out. With the information collected, the percentage frequency of occurrence of stops due to tool changes and incidents in the process was determined, and they were characterized by a Weibull distribution. Finally, to verify the effectiveness of the downtime behavior, a model was developed to simulate the availability of the stamping line in the Vensim Ple ® program.Findings: The model showed that the frequency analysis and the Weibull distribution obtained a similar behavior to reality. The study verified that it is necessary to establish a categorization of the characteristics of the downtimes, according to the characteristics of the pieces produced to evaluate the information, in this way, the times of change by tooling were established through a frequency of use and the stoppages by additional incidences to the process were better.Research limitations/implications: The basis for this study is the reliability of the information, especially in the data record. It has the disadvantage that the bias of the analyst is present when the information is recorded and analyzed.Practical implications: The methodology presented in this article is a reference for industrial applications in which it is required to establish improvement scenarios based on the reduction of stoppages present in the production lines.Originality/value: The importance of this study is that it was possible to establish a suitable workload allocation in the presses to optimize production.

Risk assessment plays a crucial and vital role in the construction sector. This research paper presents an empirical study on the risks associated with SunCon, an extraordinary pure-play construction company in Malaysia. The objectives of this study are to analyse the potential risks exposed to SunCon company and suggest risk management strategies that could help to mitigate or control those potential risks. The research conducted primarily focuses on the financial risk exposure of SunCon by analysing the secondary data that gathered from annual report. The research conducted a time-series comparative analysis of SunCon's financial performance from 2018 2022. The quantitative approach is used in this research methodology in order to evaluate the risk exposure direct to SunCon in terms of the company's financial performance. The risk measurement analyses the risk exposed including Z-score, liquidity risk, debt risk, credit risk, and interest rate risk. The findings provide an empirical analysis of SunCon's risk management strategies in terms of their financial risk over the past five years. To accomplish the objectives of the study, the study also suggested the risk control strategies that can be implemented by SunCon to mitigate the risks. In conclusion, this research provides significant implications on potential risks exposed to SunCon and the strategies to mitigate those risks. This research paper put concerns of the importance of risk management practices in the dynamic construction sector.

Musculoskeletal disorders (MSDs) are major contributors to work-related disability and time lost caused by illness. As manual material handlers, mechanics are frequently exposed to the physical risk factors for MSDs. The objective of this study is to investigate the relationship between manual materials handling and snook mital table among mechanics at tyre service center. This study was conducted in Taiping, Perak. There were 239 of mechanics from various workshops participated in these study with mainly lifting/lowering, pushing/pulling, and carrying tasks. Data were collected using a structured questionnaire and interview session which are Nordic Musculoskeletal Questionnaire (NMQ) and Snook Table. NMQ was used to evaluate the exposure of the activities and related physical risk factors that had correlated to one of the region's bodies within a 12-month period while Snook is required for evaluation of the maximum acceptable weight for lifting/lowering, pushing/pulling and carrying. In this research, most mechanics have suffered musculoskeletal symptoms in low back, shoulder, and neck pain. According to Snook analysis, most mechanics are at a medium risk of developing musculoskeletal symptoms as a result of their lifting, lowering, and carrying activity. Several definitions of pain showed a strong correlation between Snook assessment and musculoskeletal disorders. Various possible risk factors of manual materials handling activity, notably the lifting floor to knuckle and lowering floor to knuckle, each had a significant impact on the low back while shoulder and neck showed a significant relation between with lifting above shoulder. Therefore, ergonomic awareness between mechanics should be increased in order to reduce the prevalence of musculoskeletal symptoms and control the manual materials handling activity. The study will be useful to ergonomists, researchers, consultants, workshop managers, maintenance workers and others concerned with identifying ergonomic risk factor on the workplace.
