Performance Evaluation of a Job Shop using JSim

Case Description

The job shop is composed by 5 machines and 5 buffers. Each buffer is associated to the machine in front of it (e.g. B1 is associated only with M1). All the machines are physically connected each other and the path of a part type inside the system is defined by its production process. The processing time of each machine depends on the part (class) to be worked.
