Application of simulation technique for outpatient's average total time improvement

The purpose of this study is to analyze the current situation and reduce the average total time in the medical department. A virtual current model was created using discrete event simulation techniques in the Arena 14.0 Rockwell Automation software. The model is formulated from a flow chart diagram and data collection, with close consultation and approval from the authorized. Five different patients are classified by illness categories, which are endocrine, cardiac, pulmonary, nephrology, and neurological, sorted by proportion. When the simulation model is run, the results found that the current average total time spent by patients is 154.87 minutes, the lean concept to eliminate non-value-added time was highlighted to deal with ten crucial points of wait that appear during 14 hours and 7 days of model operation. To improve the total service time, three alternatives were proposed. The result of the first proposed model by adding physicians is reduced by 14.75 minutes (9.53%,). While the second solution of maximizing the service hours is reduced by 7.13 minutes (4.6%) of total time. Lastly, the third alternative, which is designed to integrate boosting the number of physicians provide and expanding the available hours of physician coverage, gives the best solution by eliminating 20.54 minutes (10.23%).
