Abstract
Although the application of Discrete Event Simulation (DES) as a validating tool may seem counterproductive, routinely reviewing an improvement that has been installed is crucial for industries to decide whether a process is optimal, requires further refinement, or must be discontinued and replaced with a better alternative. The objective of this paper is to demonstrate DES as a decision-making tool by validating the improvements of a mechanical assembly line for Printed Circuit Board Assembly (PCBA) manufacturing. As a case study, parameters connected to Overall Equipment Effectiveness (OEE) namely availability, performance, and quality were gathered from a PCBA mechanical assembly line in Company A that has shifted their primary assembly tools from conventional electrical torque screwdrivers into programmable torque screwdrivers. Through the data collection step, it was observed that the OEE improved upon implementing a programmable torque screwdriver. The assembly lines were then modelled in the DES system and information pertaining to OEE was gathered and analyzed to aid in validating the enhancement in the manufacturing line. Based on the simulation, the results obtained confirm that the OEE improves through the implementation of a programmable torque screwdriver, signifying that DES is a suitable tool to help validate an improvement in a process.
