Assembly line balancing : a case study of a hard disk factory

Abstract

In this thesis, the mathematical model to provide the balancing of assembly line has been developed by using the concept of maximize the final output and concerning the number of operators, number of tooling and space factor as its constraints. In the existing system, the spreadsheet has been used to calculate the minimum number of operators used in assembly line. By knowing the demand of output required, the number of operators and space factor will be achieved. However, other factors such as number of operators available, number of tooling available for each operation are not concerned in the existing system. Therefore, the mathematical model has been developed by concerning with these factors. The objectives of the model are that it can be used for balancing line, predicting productivity, gating the bottleneck and any sub optimal improvement. In this study, the LINDO program is used as a tool to solve the mathematical problem.
