    Patent number: 6675207
    Abstract: A compiler 2 sequentially simplifies, according to predetermined rules, a network of a processing flow defined by a PERT diagram and including a plurality of jobs executable in parallel, and determines which of any other jobs provide processing results causing each job to start and perform the processing when accepting them. Further, in the process of the simplification, if a pattern making the processing flow inexecutable, such as a loop, occurs in the network, the compiler 2 determines that the processing flow is inexecutable, and shows it to the user. If the processing flow is inexecutable, the compiler 2 generates a program for actualizing the processing of each job in the processing flow in synchronism with the processing of other jobs.
