Abstract

This project aims to improve the efficiency of a manual assembly line by employing operations analysis within the framework of Lean production. A methodology for increasing the productivity of any production process is proposed. The methodology includes the selection of a product or product family to be investigated, followed by an analysis of the current process. After documenting the present process, all assembly activities must be timed using time study techniques. Operations analysis facilitates the reduction of non-productive jobs and yields a collection of standardised work elements as well as a set of standard operating procedures. Assembly line balance and the associated operations analysis contribute to the construction or reconfiguration of an assembly system, which is the most important stage in enhancing the overall performance of an assembly line. In accordance with this methodology, two manual assembly line configurations (single stage parallel line and five-step serial line) are created for a case study. The results demonstrate that by switching to a single-stage assembly line arrangement, operator productivity is increased by removal of non-value-added tasks to the current assembly approach. Minimization of the number of workstations and maximization of the production rate are the most common goals. This report presents the reviews of different works in the area of assembly line balancing and tries to find out latest developments and trends available in industries in order to minimize the total equipment cost and number of workstations
