Girl index EssaySensitivity analysis helps to test the sensitivity of the optimum solution with respect to changes of the coefficients in the accusive function, coefficients in the constraints inequalities, or the constant terms in the constraints.For Example in the case study discussedThe unquestionable selling prices (or market values) of the two products may vary from time to time. Over what ranges can these prices change without touching the optimality of the present solution?Will the present solution remain the optimum solution if the amount of new materials, production time, or storage space is suddenly changed because of shortages, machine failures, or other events?The amount of individually type of resources needed to produce genius unit of each type of product can be either increased or decreased slightly. Will such changes affect the optimal solution ?The remark or Arrival ProcessThe input process is usually called the arrival process.Arrivals argon called clien ts.We assume that no more than one arrival can occur at a given instant.If more than one arrival can occur at a given instant, we say that bulk arrivals are allowed.Models in which arrivals are drawn from a small population are called finite source models.If a customer arrives but fails to enter the system, we say that the customer has balkedThe Output or Service ProcessTo describe the production process of a queuing system, we usually specify a probability dispersion the service time distribution which governs a customers service time.We study two arrangements of servers servers in parallel and servers in series.Servers are in parallel if all servers provide the same type of service and a customer of necessity only pass through one server to complete service.Servers are in series if a customer must pass through several servers before completing service.Queue DisciplineThe dress discipline describes the method used to determine the order inwhich customers are served.The most co mmon queue discipline is the FCFS discipline ( outset come, first served), in which customers are served in the order of their arrival.Under the LCFS discipline (last come, first served), the most recent arrivals are the first to enter service.If the next customer to enter service is every which way chosen from those customers waiting for service it is referred to as the SIRO discipline (service in random order).Finally we consider priority queuing disciplines.A priority discipline classifies each arrival into one of several categories.Each category is thence given a priority level, and within each priority level, customers enter service on a FCFS basis.
