are not undertaken. Therefore, we extended GD.findi and added the required features
described in Sect. 4.1.
Followings are the features of the developed LCS system that fulfill the requirements described in Sect. 4.1. The numbers of the following list correspond to the
numbers of the requirement list in Sect. 4.1.
1. We developed a user model module that can generate and manage the designated
number of users according to user distribution for defined market. All users
have different characters and features of the functional requirements and the way
of use, which are generated randomly according to the distribution. Moreover,
different usage modes, such as LIBs used for EVs and stationary battery (SB)
used in general household, can be individually designated in this module.
2. We developed a usage model that can calculate deterioration of items according
to the method of use defined in the user module.
3. We developed flow control functions using the agent module equipped in
GD.findi. The simulation system determines the branch to which the items should
be transferred according to the functional state of items and defined criteria.
4. The system maintains the following data related to the users, items, and processes
for enabling the analysis of the simulation results.
(a) The behavior of the items and users were recorded during the simulation so
that the state quantities of the items, requirement functions, and method of
use of the users can be identified for each individual.
(b) Processing in each process is recorded in the execution log because of which
it is possible to examine the type of process, user, kind of usage, and how
the item’s state quantity has changed as a result of processing.
(c) For all processes, the numbers of items existed for each state quantity as
stocks can be checked based on the data of execution log.

19.5.1 Life Cycle Scenario of LIBs for EVs
In Sect. 19.5, we conducted LCS taking an example of LIBs for electric cars to
verify the effectiveness of the developed LCS system in improving circulation flow
management.
We incorporated several reuse methods into the life cycle. The life cycle model
of the scenario is shown in Fig. 19.2. It is assumed that the batteries are reused when
the functions realized by the item satisfies the functions required by the users.
We considered the closed-loop and cascade reuse methods. In closed-loop reuse
(primary use), vehicles for reuse were separated into LIBs and body before EVs were
provided to the users to reuse the items efficiently. Some users want to drive long
