7. PROBLEM DEFINITION WHAT PROBLEM DEFINITION WHERE WHEN WHO WHY Queuing System Central Park Mall Saturday Visitor of Central Park Mall Massive number of visitors PROBLEM STATEMENT Massive number of visitors in Central Park mall on weekend (especially on Saturday) led to queueing in the system. If queue happens more than 1 minute and time for motorcycle to search parking more than 2 minutes, it will decrease customer satisfaction so that it will cause opportunity loss to Central Park Mall.

35. COMPARING WITH ACTUAL SYSTEM VALIDATION Visitors will first fulfill parking area block which near the mall entrance Visitors will only go to P2 if only P1 capacity is full. P2 will be open when P1 capacity almost full Visitors tend to take Server 1 rather than Server 2 (First Available) If visitors didn’t find parking at P2, they will look again the available area at P1 Actual Model How? We create dummy process from P2 to P1 for motorcycle who didn’t get parking at P2

52. Wq = 0.03 min Ws for Server 1 = 0.12 min Ws for Server 2 = 0.13 min They are within limits required from this assignment (1 min) Therefor no additional server is needed for now VERIFICATIONOUTPUT ANALYSIS Average Time in Queue and Ticketing System Lq = 0.15 entities Ls for Server 1 & 2 = 0.62 entities These number are similar with our Spreadsheet model Average Number of Entities in Queue and System

53. VERIFICATIONOUTPUT ANALYSIS Utilization of Queueing System Server 1 utilization = 33% Server 2 utilization = 14% Their average are similar with our spreadsheet model The server is under utilized even at peak time Entity Activity Average Time in system = 92.86 min Average time in waiting = 0.03 min Average time blocked = 0.92 min Entity Activity Operation Waiting Blocked

54. VERIFICATIONOUTPUT ANALYSIS Utilization of Parking Space Average time to search parking space 16 out of our parking space are utilized, 8 are continuously empty Average of empty parking space = 31.8% Average of full parking space = 28% Average # of entities in parking space system = 432 unit per hour There are overcapacity in Central Park parking system Average time = 1.69 min There are 6 locations where searching for parking space takes longer than 2 minutes (B1 area 2, 4, 5, and 6). We aim to reduce that to less than 2 minutes. There are several options: increasing parking space, better routing and capacity management

55. CONCLUSION

56. CONCLUSION CONCLUSION Peak time in Central Park happens on Saturday at 13.10-20.20 Average arrival rate in Central Park is 345 motorcycles/ hour Average service time on server 1 is 5,7 s and on server 2 is 5,8 s Queueing time in lockets is under 1 minute and searching time average is under 2 minutes, So, the parking system on Central Park is optimal. The problem that happens in Central Park is mostly because of breakdown in server. So, queue only happen when the server is breakdown.

57. RECOMENDATION

58. RECOMENDATION RECOMENDATION The problem that happens in Central Park is mostly because of breakdown in server. So, queue only happen when the server is breakdown. Better maintanance program for each server machine Increase parking space Better routing and capacity management

59. RECOMENDATION RECOMENDATION Increasing Parking Space Basement 1 location 2 = From 10 to 50 parking spaces Basement 1 location 4 = From 38 to 45 parking spaces Basement 1 location 6 = From 38 to 50 parking spaces Total Increase of parking space = 62 Average time to search parking space = 1.16 min No more spending over 2 minutes to search a parking space! Constraint : Limited Space to Expand

60. RECOMENDATION RECOMENDATION Better Routing and Capacity Management Since there are 8 parking location that is continuously empty, managementcan start routing entities there, when queue start to form Management can also partly closed several parking locations on B1 to route entities to search for parking space at B2
