Track: Undergraduate Student Paper Competition

Abstract

The footwear industry has a rich history, and producing comfort and style is one of the critical factors affecting consumers' choices in purchasing. Local shoemakers in the Philippines face challenges due to intense competition in the rapidly growing global market. This study focuses on analyzing the production of the footwear manufacturing industry to identify and provide solutions to pressing problems such as inefficiencies. The goal is to conduct a thorough analysis and improve the company's system performance measures, which include idle time, waiting time, arrival rate, and service rate. This study evaluates the production of the footwear manufacturing industry to determine and resolve inefficiencies using queuing theory, particularly the single-server, multiple-customer model, whereas the strategy provides significant insights into the manufacturing operations, which benefits the company's development and progress. Through queuing theory model application and Promodel Simulation, the three workstations have decreased idle time by 18% in sewing, 8% in upper making, and 6% in shoemaking. It proves that the study has achieved notable results in minimizing idle time thus, increasing work efficiencies using Kendall's notation. However, to further explore, this study recommends examining the monetary sector in the aspect of 5M's using the Game theory, and DEA CCR Model to equal with competitors and market as this approach may offer external factors to enhance the effectiveness and practicality of the solutions that this study has provided.
