In the past (classical supply chain) the supply of
goods generally flow starts from factory or producer, then
producer sent to a storage area called the warehouse. When
finished goods are collected, the goods from storage area or
warehouse (WH) is distributed to the distribution center (DC).
Then after the goods were placed in the Distribution center, then
the goods are shipped to the retailer (retailer). The drawback of
this system is when there is a shortage of goods at the retail level,
it takes a long time in the distribution of goods, from warehouse
into the retailer. With the approach of the Physical Internet (PI),
where the objective is to combine into a unified logistics network,
the system is inter connected, the inventory can be shared
through hubs that serve the market and distribution of resources.
In other way, the function of warehouse and distribution center
was replaced by hubs that serve to optimize transport and
inventory. Although the physical internet inventory control
model better than the classical model, but the model of inventory
management with database synchronization better than the
physical Internet. With the aproach database synchronization,
several hubs can be combined into one hubs, and the plant can
also sending goods directly to the retailer. In addition to
optimizing transport and inventory, this analysis allows to choose
a dynamic source when an order is placed: source substitution.
Although this calculation is working on a computer simulation,
the main intent of this paper is to define new research model
inventory controlling better than classical inventory model and
physical internet inventory model, which is inventory
management model in synchronized database.
