Abstract :
The impetus for this research was examining a flow shop problem in which tasks were expected to
be successively carried out with no time interval (i.e., no wait time) between them. For this reason, they
should be completed by specific dates or deadlines. In this regard, the efficiency of the models was evaluated
based on makespan. To solve the NP-Hard problem, we developed two mathematical models. Once we solved
our problem using Mixed-Integer Programming Model (henceforth MIPM) and then, we applied a Constraint
Programming Model (CPM); finally, we compared the optimality of the presented results.
