@odow
I think name(model) can be added to solution_summary(model)?
Existing:

solution_summary(; result = 1, verbose = false)
├ solver_name          : Gurobi
├ Termination

Revamped:

solution_summary(; result = 1, verbose = false)
├ My_Model was solved by Gurobi
├ Termination

where My_Model::String = name(model)

[odow]

The name is printed as part of show(::IO, ::AbstractModel).

I don't think we need to print the model name because in most cases it will be the default. The model name is also unrelated to the solution.

If you're solving multiple models in various orders and you're printing the solution summary to some sort of log file, then you should add some additional information to identify the models.

For example:

julia> using JuMP, HiGHS

julia> begin
           model = Model(HiGHS.Optimizer)
           set_silent(model)
           set_name(model, "My Model")
           @variable(model, x >= 0)
           optimize!(model)
           contents = sprint() do io
               show(io, model)
               println(io)
               show(io, solution_summary(model))
           end;
           print(contents)
       end
