Determining the Optimal Number of Packing Operators: A Simulation-Based Approach at PT Indorub Nusaraya

Introduction

In the manufacturing industry, efficient production processes are crucial for maintaining competitiveness in the global market. PT Indorub Nusaraya, a leading manufacturer of rubber gloves, faces a common challenge in the production process: the buildup or queue of sorting results that must wait for the packing process. This phenomenon not only affects productivity but also has a significant impact on the overall efficiency of the production line. In this article, we will explore the application of the queue system simulation technique in determining the minimum number of packing operators required to minimize queue buildup and maximize production efficiency.

The Importance of Determining the Number of Packing Operators

The number of packing operators is a critical factor in determining the efficiency of the production process. If too few operators are assigned to the packing process, the queue will be longer, resulting in a longer waiting time and potentially interfering with the entire production process. Conversely, if there are too many operators, there will be a waste of unnecessary resources. Therefore, the optimization of the number of operators becomes crucial in maintaining a balance between productivity and resource utilization.

The Queue System Simulation Method

The queue system simulation method allows PT Indorub Nusaraya to simulate the number of operators and analyze its impact on the waiting time and length of the queue. With this analysis, the company can find a balance point where the maximum number of operators is efficient without sacrificing productivity. The queue system in this context can be analyzed using several models, one of which is the M/M/1 queue model, which involves a service channel with the arrival of customers who follow the Poisson distribution and service time that participates in exponential distribution.

Simulation-Based Analysis

Through simulation, the company can determine how many operators are needed at one time so that the utility level remains optimal and the queue can be minimized. The simulation-based analysis involves the following steps:

Modeling the Production Process: The production process is modeled using a queue system simulation software, which takes into account the arrival rate of raw materials, the service rate of operators, and the capacity of the packing process.
Analyzing the Queue Parameters: The simulation software analyzes the queue parameters, including the average queue length, the average waiting time, and the average utilization of each operator in the packing process.
Determining the Optimal Number of Operators: Based on the analysis of the queue parameters, the simulation software determines the optimal number of operators required to minimize queue buildup and maximize production efficiency.

Benefits of the Queue System Simulation Technique

The application of the queue system simulation technique in determining the minimum number of packing operators required has several benefits, including:

Improved Production Efficiency: By minimizing queue buildup and maximizing production efficiency, the company can improve its competitiveness in the global market.
Reduced Waiting Time: The simulation-based analysis helps to reduce waiting time, which is critical in maintaining a high level of productivity.
Optimal Resource Utilization: The simulation technique ensures that the number of operators is optimized, reducing waste and unnecessary resources.

Conclusion

In conclusion, the application of the queue system simulation technique in determining the minimum number of packing operators required is a critical factor in maintaining a high level of production efficiency. By utilizing this technique, PT Indorub Nusaraya can not only determine the optimal number of operators but also improve its competitiveness in the global market. The benefits of this approach include improved production efficiency, reduced waiting time, and optimal resource utilization.
