Both physical and psychosocial may have an influence, although the task does not involve high force exertion. Experimental study was carried out to look at possible interaction between physical and psychosocial risk factors. Statistical analysis showed that pace of work as psychosocial risk factor significantly affect stress scores, fatigue scores, pain and discomfort scores. It could therefore be concluded that this particular psychosocial risk factor had substantial effect on both subjective and objective initial body responses and could disturb the internal state of the body

Technologies with greater operation time are needed to be modified or replaced as per the requirement of the current scenario. In small and medium enterprises of developing countries, almost all the reporting activities are conducted in Microsoft Excel. The manual operation in Microsoft Excel takes a long time (17.37 minutes, only if there was one order of only one article with one color) of the users; furthermore, there can also be a greater chance of error in the report. In the same way, the order costing report at the ABC footwear company of Lahore is prepared manually in Microsoft Excel which used to take a long time to be prepared along with the greater probability of errors in the report. Because of the above-mentioned reasons, the order costing report was decided to be automated with the help of visual basic for applications (VBA) in Microsoft Excel. The manual procedure...

A study was carried out to identify non-value added activities using value stream mapping in a fast moving consumer goods processing industry “Colgate Palmolive (Pakistan) Ltd. Kotri plant”. Colgate is one of the leading manufacturers of consumer goods in Pakistan. Goods mainly include tooth paste, soup, and detergents. Initially, a current value stream map was developed for each process from receiving raw material to final dispatch. Time study was conducted and the data was analyzed. Non-value added activities (which included defects, waiting time, over production and excess motion) were identified, and were highlighted on the future state value stream map. It could be concluded that value stream mapping can be effectively used in processing industry to identify non-value added activities. Keywords— Lean manufa...

This study explores the opportunities to increase the product safety by analyzing the performance of suppliers and production-distribution system. More precisely, this research analyzes the impact of suppliers’ performance on overall profit of supply chain and impact of increasing consumer safety on total profit of supply chain. The novelty of this study is the development of integrated supplier selection and production-distribution model considering consumer risk and product safety. The proposed model is a grey multiobjective model which considers imprecise information as grey parameters. Furthermore, a novel grey-weighted ε-constrained (GWECON) method is developed to solve the proposed multiobjective model.

A particular objective of the study was to investigate whether physical and cognitive demands may interact in their influences on these effects. An assembly task was simulated in the laboratory and the level of pacing imposed, work height and memory load within the task were all varied. The results showed that the type of pacing commonly imposed (as is common with a lean manufacturing Takt time system in industry) can significantly affect both performance and perceived workload and stress. Physical demands (through work height affecting posture) and mental demand (through memory load) were also found to have significant effects, as would be expected from the many studies of these in the literature. More importantly, some interactions were found between pacing and work height...
