| Summary: | UPT Pengadaan ITB is an internal functional unit which responsible for managing
all procurement of goods and services for all work units within the scope of ITB.
UPT Pengadaan ITB have an issue related to fulfillment time of paper and cartridge
group of goods in 46 to 69 days range which is not optimal. The most ordered group
of goods in ITB is paper with 75,920 orders, while cartridge has 8,544 orders as
6th most ordered goods. Hence, minimization of fulfillment time is needed to be done
by UPT Pengadaan ITB.
On the first stage of this research, analysis of the existing business processes in
general is conducted. The analysis was carried out for identify non value added
processes to be replaced or removed. Then implementation of inventory system is
chosen based on the research as a replacement for those non value added
processes. Detail of inventory system implementation divided into vendor managed
inventory (VMI), self-managed by UPT Pengadaan ITB, and 3rd party logisticss
(3PL). This research then conducts cost evaluation and performance evaluation on
all three proposed alternative systems. Cost evaluation is carried out by taking into
relevant cost components in each system, while the evaluation of performance is
carried out using the Monte Carlo simulation method.
After simulation and cost evaluation were carried out for all proposed alternative
systems in conjunction with comparing to existing system, it was concluded that the
implementation of the inventory management system recommended using vendor
managed inventory (VMI). Proposed alternative system VMI can reduce fulfillment
time 74,6% to 11,7 working days. Besides, total time needed for 5 years period of
time is reduced 70,9% to 745,98 working days from 2560,03 working days. Cost
for implementation VMI is increased 18,58% estimated at Rp2,082,611,616.62,
while the cost of the existing system is Rp. 1,756,357,184.48. |
