The current state of global business competition is resulting in an ongoing struggle for a sufficient market share, which is typically not only attained by lowering prices but is instead more successfully accomplished by continuously introducing new innovations, functions, and features at all levels in a company. But the consumers are not getting the proper value and desired functionalities from a market product. This paper is about analyzing the value of an industrial product which is a rechargeable fan. Product value is determined by comparing between systematic features and product costs. The main focus of VA is to identify and get rid of product or service features that don't really add value for the customer but add costs to the production process. In contrast to replacing the old product with a less desirable substitute, the VA method guarantees a better product or service for the consumer at a low cost. This study seeks to present a comprehensive analysis of using the TRIZ method in raising the value of a rechargeable fan. The recommendation stage explains the best alternative design for a rechargeable fan and the changes that should be made to increase the value of the product. [ABSTRACT FROM AUTHOR]

Due to competition a good number of E-commerce sites are trying to improve their systematic infrastructure according to customers' choices. Coping up with this, E-commerce companies are facing challenges in the business environment of Bangladesh. Our study is to analyze the challenges of our current e-commerce sector in Bangladesh from both customer and company point of view. From the secondary data, seven challenging factors (customers' point of view) and seven challenging factors (company' spoint of view) were selected. Firstly, two different surveys were launched and Likert scale was analyzed. By one sample t-test, some challenges were rejected due to their low significance value. The RI (Relative importance index) method was applied for the rest of the factors. According to the RII value, challenging factors were ranked. In both perspectives, Trust factor has been ranked as the most significant challenge. Other factors such as product quality, price issue etc. (customers' perspective) and strategicissues, transportation issues etc. (Company's perspective) have been ranked as very important challenges. Necessary steps should be taken to overcome these challenges according to their importance. [ABSTRACT FROM AUTHOR]

Consumer Behavior is the behavior that customers display in searching for, purchasing, using, evaluating, and disposing of products and services that they expect will satisfy their needs. Consumer behavior focuses on how individuals make decisions to spend their available resources like time, money, effort etc. on consumption-related items. The study is on consumer behavior towards electronic goods in festival season in Bangladesh. Methodology applied here is a face-to-face interview and questionary survey and analysis pattern considered hypothesis test. Findings from the survey are - consumer tastes and preferences are changing day by day; during the festival season, sales of electronic goods increase; increase of new technology use causes more customer satisfaction and interest; advertising programs and media attract the targeted customer; demand for goods depends on better quality at a reasonable cost; discount facilities in electronics goods increases the sells during festival seasons; sales of electronics goods increased 20% to 30% during the festival season; the reason for purchase during festival season is having more disposable income like bonus; discount facilities increase the sales by about 20% to 30% & sometimes more than 30%; it is found that TV sale is more during Eid-ul-fitr, refrigerator sale is more during Eid-ul-Azha and TV sales are more during gaming season like world cup time in Bangladesh. Now-a-days, consumers arepurchasing online and getting delivered to their home. Such analysis can help to get better forecast and to produce goods more for festival and to bring different innovation in product. [ABSTRACT FROM AUTHOR]

The ready-made garment (RMG) industry in Bangladesh, with the gradual increase of manufacturing costs, is in indispensable requirement to initiate improvement in manufacturing to continue sustainable growth for long run. With the customer expectation, it is required for the manufacturer to improve capacity, on-time delivery, efficiency, and financial condition. To achieve that, it is required to optimize cycle time to improve capacity, reduce work-inprocess (WIP) and throughput time to get faster flow and delivery, optimize process and resources fulfilling the expected quality. This study aims to improve manufacturing performance using a layout optimization methodology and workplace engineering through the work study. The proposed methodology is implemented in a RMG finishing production line. The results show that, about 19.5 sec cycle time is reduced by increasing 16 pcs capacity per hour from the line. Also, 2 manpower is optimized from 8 lines through process elimination which impacts 3% efficiency improvement, whereas throughput time is reduced to 26 min by cycle time minimization and WIP reduction to improve on-time delivery. These are the two most effective tools for improving the workplace, work environment as well as manufacturing performance. The proposed layout optimization and workplace engineering can be implemented in any type of industry to improve lead time, quality, material handling as well as customer satisfaction.

Lean and Six-sigma are well implemented in different countries but it is yet to find the implementation scenario in ready-made garment industry of Bangladesh. RMG growth in Bangladesh is for day-to-day learnings only. This research work is on finding the current scenario of structured implementation of Lean and Six-Sigma in RMG industry of Bangladesh. A survey is conducted on industrial engineers and management employees covering 270 factories of Bangladesh RMG industry. The results found that only 8.5% of the industries have implemented Lean Six-Sigma up to some extent and major 91.5% industry yet not implemented any of these. The theoretical and practical knowledge level of structured Lean and Six-Sigma is identified as staff of 85% factory have below 25% knowledge level, staff of 15% factory have 25%-50% knowledge level and none of the factory staff have above 50% knowledge on Lean Six-Sigma. The challenge of implementation of Lean Six-Sigma are lack of training and knowledge, costly training programs, believe of the benefit of training and development, improper data records, not encouraging analytical activity, failure of transforming data to information etc. However, such findings will help to understand the current scenario and improvement areas for this industry.

Environmental friendly products and materials are very much important for the sustainability of human being in this earth. For this reason, researchers are focusing on it. As synthetic fiber has a negative impact on environment, these are being replaced by the natural fiber in the reinforcement of composites. In this study, corn cob particles and palmyra fruit fiber are used as reinforcement in epoxy based composite. As a fabrication technique hand lay-up method is used. Weight percentage of resin and hardener in composite, weight percentage ratio of resin and hardener, weight percentage ratio of corn cob particles and palmyra fruit fiber, and also thickness of the composite were taken as control factors for the fabrication of the composites. Experiments were designed according to Taguchi L9 orthogonal array. Then the water absorption characteristic was observed for different experiments. Optimum control factors were chosen using Taguchi analysis. Also different statistical analysis was done for finding the effect of the control parameters on water absorption property of the natural fiber reinforced composite. [ABSTRACT FROM AUTHOR]
