Flow shop scheduling deals with the determination of optimal sequence jobs processing on machines in a fixed order main objective consisting minimizing completion time all (makespan). This type problem appears many industrial and production planning applications. study proposes new bi-objective mixed-integer programming model for solving synchronous flow problems time. The functions are total m...

  Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

In 2002, J.M.Rassias (Uniqueness of quasi-regular solutions for bi-parabolic elliptic bi-hyperbolic Tricomi problem, Complex Variables, 47 (8) (2002), 707-718) imposed and investigated the biparabolic elliptic bi-hyperbolic mixed type partial differential equation of second order. In the present paper some boundary-value problems with non-local initial condition for model and degenerate parabol...

In this paper, a bi- objective Operating Theater scheduling is proposed. The problem subject to order and assignment constraints. first the minimization of operating theater opening total time also called makespan in manufacturing systems while second maximize constraints satisfaction. considered as two-stage hybrid flow shop with blocking. Several metaheuristics are compared: firefly algorithm...
