This study focuses on the process flow of the third-party logistic company and aims to analyze the production system of the company using Promodel software, a computer-aided drafting software utilized to simulate operational models of a company. Process enhancement brings about the key objective of the study since it is the most accessible and requires less intervention to the working environment. While the manpower and material are insufficient, the study aims to mitigate the problems by providing suggestions regarding the company’s process. This paper found operational inefficiencies resulting from poor operation management by using the Ishikawa diagram and considered the need for change by accounting for the current resources the company has. By using Promodel, process observation, and time-and-motion study, this paper identified the blocked, operational, and moving rate of the company. The assembly line proved to be inefficient with the company’s current resources in which the study simulated and proposed a synchronous process model. By implementing a fitting manufacturing model for the company, the ability to be productive will be easily achieved. In light of this, the study aims to coPackage entry to each location in the Proposed Model from Promodelntribute the effectiveness of the synchronous process model to companies that find limitations to their manpower and locations.
