Performance optimization of pillow sheet set sewing assembly line by SAM analysis and lean manufacturing techniques of method study & work measurement

Abdul Haseeb — 2023-01-31

This research was conducted to enhance the productivity of the targeted sewing line at the ABC textile company. The existing SAMs, the capacity of the sewing line for various operations, and several required machines were collected. Moreover, the obtained figures were observed and analyzed by using time study and motion study, and certain improvements were made at the sewing line. Results indicated that SAMs for operations A and B were minimized by -13.64% and -14.54% respectively; whereas, SAM for operation C was increased by 16.67%. Machine requirement for operation C was increased by 100%; moreover, the capacity for operations A, B, and C was increased by 12%, 12.69%, and 40% respectively. When it is to production activities, the little improvements play a significant role in boosting the productivity of the production system. Optimal allocation of human resources, machines, and time are the benefits of line balancing. This can be made possible with the application of the line-balancing framework. With every passing day, the nature and type of article vary at the sewing line thus it is highly needed for the company to get the model developed for an automated line balancing application. Moreover, this work can be extended by the development of a line-balancing framework considering the nature of production.

Automation of material cost comparative analysis report using VBA Excel: a case of footwear company of Lahore

Muhammad Ahmed Kalwar — 2023-01-31

Small and medium-sized firms in developing countries perform the majority of all reporting tasks in Microsoft excel. The material cost comparative analysis (MCCA) report took the user 58.51 minutes to complete and there was also a higher likelihood of calculation error. The report was created in Microsoft excel by the Lahore-based ABC footwear business. This used to take a lot of time to produce and there was a higher chance that the report would contain errors. This is because Microsoft excel visual basic for applications was used to automate the report. This report's manual preparation method was compiled by the company’s planning and costing division. Each activity was listed, followed by the completion of a time study. VBA macros were built in Excel to automate all manual report-related tasks and reduce the possibility of human error. Conditional statements were applied to help automated decision-making. To enable command buttons to run macros, one user form was created. There were various worksheets included in the MCA template. The automated template was found to consume only 16.26 minutes and it was quicker than the current technique.

Re-designing of hair clipper using design for manufacturing and assembly

Abhishek Prasad — 2023-01-31

Evaluating the product functions and associating them with the manufacturing technique is crucial to reducing the manufacturing cost. Design for Manufacturing and Assembly (DFMA) is a concurrent engineering technique that plays a vital role in redesigning of existing product or service by reducing its manufacturing and assembly cost and time, have the desired level of quality and reliability. In this research work is apply DFMA on existing hair clipper and decrease the net manufacturing cost of the hair clipper. Hair clipper is very popular for at-home use and is seen as an essential tool in hair grooming. The analysis of design for manufacturing and assembly is done using guideline of Boothroyd Dewhurst DFMA. The components of the Hair clipper were undergone alteration by using DFMA and redesigned approaches. In the same platform, the actual model had the redesign. The assembly time for redesign exhibited an enhancement of 49.25% where the assembly time was decreased from 322.91s to 163.81s and design efficiency was improved 7.219% from 7.432% to 14.651%. Hence, the best design of hair clipper was made which is having optimal value is achieved.

Identifying the critical success practices of sustainability and their implementation in the manufacturing sector of Pakistan: an exploratory factor analysis

Asif Nawaz Wassan — 2023-01-31

The concept of sustainability is increasingly discussed in organizations whether they are large firms or SMEs as a sign of environmental awareness of consumer knowledge of product quality. This study provides a better understanding of how sustainability practices are being implemented in the manufacturing sector which is one of the most promising sectors in the world. The aim of this paper is to identify the critical success factors of sustainability and their implementation in the manufacturing industries. The data was collected through a questionnaire survey from the manufacturing industries of Karachi and Hyderabad Sindh Pakistan. In-depth information about the sustainability concept in the company was collected by using the questionnaire survey technique. The data was analysed by using descriptive and exploratory factor analysis. The study also developed a conceptual framework that helps in improving the business, sustainability, and financial performance. This framework consists of three practices (economic, environmental and social) with twelve sub-practices (Cost management, research and development, limited landfilling, Environmental pollution, product lifecycle, resource consumption, public welfare, industrial health and safety, and stakeholder) of sustainability, these practices aim is to bring effective performance in the manufacturing industries of Pakistan. The proposed framework of this study will give an important vision that will enable Pakistani industries to get benefit from the sustainability implementation. Moreover, this study will also provide an understanding of how sustainability would help manufacturing industries to obtain a competitive advantage in the global marketplace. The finding of this study would serve as a guideline for business management as they developed a strategy for achieving sustainable performance. Additionally, this study will offer a preliminary step for future research on manufacturing industries in sustainable manufacturing.

Identifying the critical success factors of total quality management implementation in manufacturing industry of Pakistan: an exploratory factor analysis

Asif Nawaz Wassan — 2023-01-31

Total quality management (TQM) is a management philosophy that focuses on continuous quality improvement across all parts of a company. Its key goals are to satisfy customers and stay in business. As a result, it's critical to identify the elements that lead to successful TQM implementation. This study also proposed a framework that helps organizations in their success. To achieve this goal, various critical success factors (CSFs) that contribute to organizational growth success were identified. The major purpose of this research is to identify critical success factors for TQM implementation in the manufacturing industry. For this aim, the study was deployed from an extensive literature review, and the questionnaire was used as a research instrument to specify the essential CSFs in different manufacturing industries. Around 300 questionnaires were issued to top management of manufacturing enterprises in Sindh Pakistan (both public and commercial sectors). The structured survey received 82 valid responses, which were then analyzed by using factor analysis. Finally, the study's findings highlighted the five CSFs (customer satisfaction, employee involvement, training and education, continuous improvement, employee encouragement, and service quality) as the most important aspects in building an effective framework for successful TQM adoption in manufacturing industries. The findings of this study will assist senior management in the implementation of a TQM program and resource allocation that will produce the greatest results in terms of increased returns and stakeholder value.
