Abstract Stochastic programming methods are an important for the investigation of purposeful processes in production planning, engineering, agriculture, telecommunications, transportation models, military purposes and technology. Linear programming under uncertainty or, as it sometimes termed, Stochastic programming with recourse, was suggested by (Beale and Dantzig). Charnes and Cooper have presented a trial approach called chance-constrained programming in which each constraint must be satisfied with a certain tolerance probability. In this thesis a solution for stochastic nonlinear programming problem is presented by developing a new theorem. This solution required converting the stochastic nonlinear programming problem to a deterministic nonlinear programming problem, which can be solved by the separable programming method. The thesis comprises five chapters, these are organized as follows: Chapter one: Introduction and Basic Concepts In this chapter we presented a survey concerning some definitions and fundamental results of probability theory required for stochastic processes, the solution of nonlinear programming methods, and stochastic programming methods. In addition, the formulation of stochastic nonlinear programming problem. iii Chapter two: Nonlinear Programming Methods In this chapter the nonlinear programming methods is introduced. This consists of unconstrained nonlinear programming methods and constrained nonlinear programming methods. Chapter three: Stochastic Processes In this chapter we presented the stochastic processes, its types, classifications, practical applications, and some examples. Also the stochastic programming and the stochastic linear programming are presented. Chapter four: Stochastic Nonlinear Programming Problem Solution A solution for stochastic nonlinear programming problem is proposed. This solution required converting the stochastic nonlinear programming problem to a deterministic nonlinear programming problem through developing the theorem which solves stochastic linear programming problem to a new one to solve the stochastic nonlinear programming problem (theorem 4.3.1), which can be solved by the separable programming method. We proved that theorem and verified it by solving two examples by the stochastic nonlinear programming problem (examples 4.1 and 4.2). Chapter five: conclusion and future work In this chapter provides the conclusions arrived in carrying out this thesis and makes recommendations in the field of stochastic nonlinear programming problems. |
