The classical <i>activity cycle diagram</i> (ACD), which is a bipartite directed graph, is easy to learn and use for describing the dynamic behavior of a <i>discrete-event system</i>. However, the complexity of the classical ACD model increases rapidly as the system size increases. This article presents an enriched ACD called the <i>parameterized</i> ACD(More)
Activity cycle diagram (ACD), which is essentially a timed Petri net, is one of the oldest formal modeling tools for discrete-event systems, and a flexible manufacturing system (FMS) is a highly automated job shop that is used widely in mechanical and electronics industries. Previous FMS modeling studies have indicated that formal modeling of real-life (or(More)
Recently, the growth of outpatient clinic capacity has not matched the increasing demand on outpatient clinics, which has led to long waiting times for patients and overtime work for clinic staff. This has three significant negative effects on patients and staff: (1) patients' distrust of the procedures for treating outpatients increases, (2) nurses' stress(More)
