Fundamentals of Simulation Modeling
Production systems are dynamic systems, into which raw parts enter and, after being processed by machines, exit as finished products. A dynamic system is a collection of entities that evolve over time according to certain laws. The variables that describe the system at each time instant constitute the state of the system and are called the state variables. Evolution can be conceptualized as a sequence of states that the system visits during a period of observation. We shall refer to such sequence as the trajectory or sample path of the system. A model of a dynamic system is a symbolic expression of the underlying laws that relate the current state to past system states.
