The four phases as described below in Figure 2.

The goal when designing a supply chain network is to
maximize the firm’s profits whilst satisfying customer needs in terms of demand
and responsiveness (Chopra and Meindl, 2010). At highest level the performance
of a warehouse network must be evaluated along two dimensions: a) customer
requirements that are met b) Cost of meeting those customer requirements
(Chopra and Meindl, 2010). (Chopra and Meindl, 2010) suggest factors that can
be influenced by the structure of distribution network are:

a)       Response time

ASML has different customers with different SLA’s, some
customers have very tight SLA’s, while some customers are willing to wait
longer to receive service and spare parts. With introduction of NXE1
systems and for  customers who are using
NXE systems, capacity of a warehouse must also be taken into consideration, because
a ASML warehouse is used not only to store service and spare parts but also
stores complete modules of machines before these machines are installed at
customer location. Once the tools for
a NXE system arrive in the warehouse, the logistics demand for space goes up,
all these tools and service parts must be stored in the local warehouse, before
a machine is installed at the customer location: One NXE machine requires 20
truckloads carrying six containers and 170 crates.

 “To design an effective network
a manager must consider all the factors described in the Figure 4 (table)”
given below (Chopra and Meindl, 2010, pp 122). This table (figure 2) as suggested
in (Chopra and Meindl, 2010) describes framework for network design decision
which will help ASML in designing right regional distribution network. Global
network design decisions are made in four phases as described below in Figure
2. The first phase of network design can help an organization framing  high level of its supply chain. The second
phase is to identify regions where distribution centres will be located, their
roles and capacity. For phase three potential sites can be selected within each
region where distribution centres will be located . In phase four precise
location and capacity allocation for each distribution center can be selected
(Chopra and Meindl, 2010).
