Introduction
The objective of supply chain logistics - to provide goods to the right
place at the right time in the right quantity - is easy to understand,
but achieving this objective while minimizing costs is not an easy task.
Each
decision made at one level of the supply chain has an impact on another
level. The goal of conducting a network analysis is to determine: "From
how many facilities, which ones and how will which products service which
customers?" By optimizing the network while factoring these variables
(and more) into the equation, a company can save between 5 percent and
15 percent of their supply chain costs.
This
is Part One of a two-part note on Optimizing The Supply Chain Network.
Part Two will discuss the Network Design Elements.
A
Network Analysis Example
If a company increases the number of distribution centers (DCs), they
will be closer to their customer base, reduce outbound transportation
costs and improve service levels. On the other hand, this solution will
have a negative impact on the Inventory Carrying Costs (ICCs), inbound
transportation costs and fixed costs at the DCs, so the total logistics
costs may not be reduced. Figure 1 illustrates this example and the relationship
between different elements of a supply chain network analysis and the
total cost.

Two
Levels Of Supply Chain Optimization
Complex supply chain decisions are made at two levels: operational and
strategic. The operational decisions involve satisfying demand with high
service levels, while trying to minimize costs within the constraints
of an existing network. Different decision support tools, such as manufacturing
planning systems and transportation management systems, are available
to assist enterprises in making the best decisions regarding optimizing
and scheduling production runs and raw material utilization, as well as
delivery routes and frequencies. Enterprises have created value by using
these tools in their daily operations.
The
strategic decisions include questions about the number, type and location
of manufacturing and distribution facilities, as well as the transportation
channels and modes used to service customers. The target service level
itself is an important strategic element. Just as with operational decisions,
excellent tools are available to optimize these strategic decisions and,
in so doing, create value for the enterprise. By taking advantage of the
tools' powerful linear programming and algorithms, between 5 percent and
15 percent of total supply chain costs can routinely be saved.
Why
Perform A Network Design Analysis
Changes in supply chain strategy directly impact the performance of a
supply chain network, and network changes, in turn, directly impact daily
operations. Major changes to the supply chain strategy (from customer
demand to supply), as well as changes to the supply chain (network) itself
are good reasons to perform a network analysis. (See Figure 2.)
Figure
2. Examples of triggers to performing a network analysis
- Mergers
and acquisitions
-
Significant increase/decrease in market demand, new geographic
markets or new market segments
-
Network reconfiguration (lease expiry, new facility purchase)
-
Service level improvement initiatives and cost impact evaluations
-
Poor performance of logistics operations (costs are above average,
increase in logistics cost as a percentage of sales, low inventory
turns)
-
Consolidation of purchasing/sourcing operations
-
Consolidation of shipments across company division

The
strategic plan will have a significant impact on operational planning
and optimization, because strategic planning outputs or elements will
often form the constraints with which operational plans must comply. For
example, an element of the Supply Chain Strategy might require that customers
be delivered to within one day of ordering for certain items. This strategic
element has a clear impact on transportation planning, as well as on inventory
planning. Other network design elements also have a clear impact on operational
planning elements. Optimizing these network design elements will improve
the basis on which operational plans are built.
