Each multi valued attribute maps into a separate table.
Include also an attribute for the primary key of the entity and relationship type which the attribute belongs to.
The relvar has an attribute for each simple attribute of the multi valued attribute.
This is also a foreign key.
The primary key of this relvar is the combination of all the attributes if the multi valued attribute is simple.
If the multi-valued attribute is composite, the primary key of this relvar may be a combination of some of the attributes.
