Thanks for reply.
I tried using
./fuseki-server --rdfs
but this return "No value for argument : rdfs"
Can you help me fix this?

Give it a schema file to use:

--rdfs=FILE

Also note that:

     (?x rdfs:subClassOf ?y) and (?y rdfs:subClassOf ?z)

do not entail

     (?x rdf:type ?z)

Perhaps you meant you are starting with:

     (?x rdf:type ?y) and (?y rdfs:subClassOf ?z)

I guess you have to use an assembler file to configure reasoning, at
least for anything beyond RDFS (for just RDFS Simple, you can start
fuseki with --rdfs param)

Here is a blog post how to do this:
