This project is a case study conducted in a manufacturing company aiming at improving its productivity using line balancing techniques. Waste reduction, especially the time waste, is an important factor to shrink the manufacturing cost. The main purpose of this project is to suggest a better line balancing approach with an aim of reducing the idle time, work station number, and manpower requirement while improving the efficiency to meet the target production in the apparel manufacturing organization. For accomplishing the purpose, different line balancing methods named Largest Candidate Rule, Kilbridge & Wester method, and Ranked Positional Weight method carried out for analyzing the line efficiency, production rate, work station number, manpower requirement, and time utilization. Finally, an efficient and balanced line were proposed with respect to the auspicious outcome of the production area. Also, by using the line balancing techniques, a new sequence of work has been developed to arrange the work elements into the workstation. Some optimum layout has been proposed that has minimized the idle time and manpower requirement.

The aim of this study is to implement Total Productive Maintenance (TPM) in a continuous injection molding industry. By implementing TPM, the industry can increase their Overall Equipment Effectiveness (OEE) and productivity. Before implementing TPM, overall equipment efficiency, availability rate, performance rate, and quality rate of the injection molding machine were 74.9%, 88.54%, 88.5%, and 95.6%, respectively. It needs to be improved for good operating condition of machines. In this paper, some tools are suggested to improve their productivity and maintenance procedure. These tools are cause and effect diagram, Pareto chart, WWBLA, and preventive maintenance schedule. TPM program is to change the culture of the company maintenance policy with involvement of all employees toward the maintenance system of the company. Through the proper planning of maintenance schedule, productivity can be improved. This schedule helps to maintain machines in good operating conditions as well as a good OEE value, and a world class standard OEE is achieved.

The role of primary education is to ensure the broad-based development of pupils. This means ensuring that all pupils are able to develop their cognitive, social, emotional, cultural, and physical skills to the best of their abilities and preparing them for their further school career. It is known that education in Bangladesh is highly subsided. The government has given the highest importance to the education sector to ensure education for all. A large percentage of a country's national budget is set to promote education and make it more accessible. But the education system of Bangladesh faces several problems. Low performances in primary levels and dropout are matters of concern because the low performances can result of poverty, widening disparities in education opportunities and facilities, poor school attendance, less contact time in school, lack of skilled school teachers, and lack of coordination between parents and the teachers. For that reasons, this research is conducted to implement the Total Quality Management (TQM) to improve the condition and the quality of the primary education system. Total Quality Management is a tool for ensuring proper quality in the entire organization. The main objective of the research is to eliminate problems such as the lack of quality of teachers and to improve the relation between teachers, students, and parents. Another aim of this research is to improve the quality of the environment of the class room in order to motivate the students to go to school; so, the dropout can be reduced.
