Abstract: According to the characteristics of mixed processes, a
practical scheduling method is proposed. The method contains three
parts. First, a macro process planning is obtained by merging some
relevant process steps. On the basis of this macro process planning,
mixed processes are regarded as discrete processes. Second, by referring
to priority and setup time of process steps, static scheduling is
completed. Third, in order to solve some specific issues in the mixed
processes and improve the flexibility of the proposed method, some key
points are discussed. The method has been used in Northwest Zirconium
Co. Ltd. and running results illustrate its effectiveness.
