Description:
For an industrial enterprise, one of key business processes is the
supply chain process. The primary goals of supply chain management
are to maintain high service levels while minimizing costs.
The key problem in supply chain management is how to balance
inventory. Variability in demand and process times, complexity of
the supply chain objects, and system dynamics create uncertainty
that can only be modeled and analyzed with a tool like SIMPROCESS.
This demonstration model represents a typical supply chain for an
industrial enterprise with 4 factories, 3 suppliers, and 4 customers
(distributors) in the United States. This high level model of the supply
chain demonstrates how SIMPROCESS can help define the
major processes, resources, and entities involved in providing products
to customers. The model also demonstrate the power of the
hierarchical simulation capability of SIMPROCESS. To view the
power of hierarchical modeling, drill down into the West Coast factory
(F1). Below is a brief description of the model elements.
Customers
Customers demand products from the factories. The customer process
defines the frequency and quantity of demand from the factories.
Suppliers
Suppliers supply raw materials (supplies or components) to the factories.
Each supplier produces different types of raw materials and
ships to each factory.
Factories
Factories assemble the components, package the goods (inventory)
and ship them to customers. A factory typically ships to customers
in its geographic region. For example, the west coast factory
receives 80 percent of its orders from the west coast customer and
20 percent of its orders from the southwest customer.
Such a model of a supply chain can be enhanced to answer questions
such as:
- What if the demand for certain products from the east coast
supplier doubles?
- What if the west coast supplier is having manufacturing problems
with a product line?
- What if we use alternative transportation carriers to deliver
products to customers?
- What if we outsource the assembly process?
