                 Nom_Operatrice = e.Nom_Operatrice,
                 Prenom_Operatrice = e.Prenom_Operatrice,

The problem is that the result of the select is IQueryable<AnonymousType#1> but the model is IEnumerable<operatriceviewmodel>.
Either:
change the type of the model to the non-generic IEnumerable or
use var model = ( from ... select ...) or
change the select to return operatriceviewmodel values.

Assuming that the properties of the anonymous type are actually the same properties the ViewModel has, just adding one word to the query should do the trick:

C#

IEnumerable<operatriceviewmodel> model = null;
 
model=  (
            from e in db.Operatrices
            join j in db.Operations
            on e.Id_Operatrice equals j.Id_Operatrice
            select new operatriceviewmodel // <--- here
            {
                Id_Operatrice = e.Id_Operatrice,
                Nom_Operatrice = e.Nom_Operatrice,
                Prenom_Operatrice = e.Prenom_Operatrice,
                Designation = j.Designation
            }
        );
return View(model);
