Olympic Games helding, the staffs of logistics
department often has to work overtime.
(2) Forklifts lending simulation result. Under the
circumstances of 6 forklifts, the simulation result
shows that average waiting probability of trucks
lending is 3.2%. The waiting time of forklifts
lending is about 0.51 hours. It indicates that the
process of trucks lending is relatively smooth. Other
departments can borrow forklifts nearly without
waiting. It can meet the needs of other departments
very well.
5.2 Resources Utilization Optimization
From the simulation results, it is found that there is
room for improvement in the logistics resources
planning in this stadium. There is lot of work to do
on optimizing resources so as to improve resource
utilization rates.
From the simulation result, we find that the load
rate of workers and forklifts utilization are lower.
The load rate of workers is only 33%, their work rate
could be improved.
The number of forklifts is 6. In this situation, it
may be considered to streamlining appropriately.
But the utilization of fork trucks is only about 30.2%.
We set the number of fork trucks from 6 to 5. In this
solution, the utilization could be improved to 78%.
The optimization work on forklifts’ utilization
has been made. When the number of forklifts is 4,the
simulation result shows that the utilization of
forklifts is 92%. When the number of forklifts is 3,
the utilization is 98%. The result is shown as Fig.9.
So we think that 5 forklifts are better for this
stadium. The forklifts could be working in a good
state.
We have got received order quantity of this
stadium, which is shown as Fig.10. To this stadium,
order quantity median value is 4 sheets a day. Its
mean value is 6 sheets and stand deviation is 8.
Considering 90% probability, this stadium received
order quantity is under 16 sheets .
So we can get coefficient to determine numbers
of fork trucks and workers in a stadium.
Fork truck coefficient is:
16
3.2
5
=
Worker coefficent is:
16
1.6
10
=
So we think that in this stadium, 3.2 order sheets
for a fork truck and 1.6 sheets for a worker are
proper durden. By using these logistics cofficent, we
can get numbers of fork trucks and workers in a
stadium easily.
6 CONCLUSIONS
The logistics system of this stadium, there is certain
of balance between fork trucks lending services and
material handling. The logistics department's main
task is to receive and delivery material, in order to
maintain the high efficiency of this service, it is
bound to occupy quite a lot of material resources.

Figure 10: Received Order Quantity of this Stadium.
Based on the analysis above, this paper considers
that the proportion of workers and fork trucks could
be adjusted. The number of workers can be cut down
to 10 and the fork trucks can be cut down to 5. In the
Olympic stadiums, the configuration ratio of actual
workers and logistics tools is fixed, which is due to
operational efficiency and safety. If we can
flexibility adjusts the amount of forklifts and
workers based on actual situation, the overall
flexibility of the system can be enhanced, which
makes the system efficiency improve. By studying
simulation results, we think that 3.2 order sheets for
a fork truck and 1.6 orders sheets for a worker are
proper burden coefficient. These coefficient could
help us to plan logistics resources readily.
