(.):  The application of one exact and two approximate methods for solving extended permutation flow shop problems of scheduling theory is considered: the branch and bound method, the ant colony method, and simulated annealing. Extensions of flow shop problems defined by recursive functions and using the $and$ predicate are given. This model allows solving planning problems for certain types of assembly production. The problems are generated by a parameterized generator of pseudo-random directed acyclic graphs, which made it possible to perform tests for 14, 20, 100, and 200 jobs and calculate the solution search time and makespan value for them. The paper also discusses a fairly common SDST manufacturing problem with sequence-dependent setup times. A corresponding recursive function is defined for that problem. The work performed has shown that the recursive PFSP model is viable and deserves further development. The development of new applied recursive functions for solving scheduling theory problems allows the use of the considered algorithms and optimization programs, since the recursive functions have one set of arguments and the approximate methods used are based on the definition of an elementary permutation and the requirement of computability of the recursive function.
