In recently, with the development of science and technology, the interior factors (technologies, machines and products) and exterior factors (the quality of labors, management and market) keep changing constantly. In order to adapt to this change, numerous new technologies and management methods appeared, which include "flexible production", a more successful and extensive production model. After developed in the pure realm of technology for several decades, "flexibility" has infiltrated into most dimensions of production system and brought out a set of integrative theories.Production system flexibility, including technique flexibility, resource flexibility and management flexibility, is one of abilities of production system which makes it possible that the system can adapt to the change of environment. Two indispensable qualities of a successful flexible production system are given as below: 1. The production system can response quickly and timely to the change of the outer or inner environment. It has the ability of taking advantages of the changing environment to improve itself and avoid or decrease the influence of disadvantages; 2. In a dynamic situation, the production system can exert adequately its ability of flexibility thought limited investment. Proper means should be found to bring out optimal benefits.Take these two factors into account, people have to solve three problems: 1. Before built, a flow shop's technique flexibility should be determined, e.g. people have to determine how much flexibility a flow shop has and the benefits it can produce; 2. After a flow shop has been built, people have to find out how to plan a optimal scheduling, which will help the flow shop to exert its producing ability; 3. How to constitute a proper management system.Because of a variety of environment and concepts, many questions of flexible flow shop still remain unanswered, but most researches focus on qualitative analyses. Therefore, this paper uses quantitative and qualitative analysis in combination in order to obtain some valuable theories and methods.This paper contains three parts: 1. The method of choosing technique flexibility, including question analysis, influences of various factors and resolvents; 2. Scheduling of flexible-resource flow shop, including programming model, resource distribution principle and branch-and-bound algorithm; 3. Choosing the flow shop scheduling. Partan algorithm.Eventually, this paper proposes some means on how to determine the bottleneck operation by statistic analysis.
