Queuing Theory

This book contains the performance measures of different models used in Queuing Theory. The applications in specific sectors are discussed. Case study models are discussed and new methods have been proposed to get optimized cost and reduced waiting time. Waiting lines or queues are a common phenomenon in life, especially in the province of organizations that are for profit making. Queues are common in such places as petrol or filling stations, supermarkets stores, clinics, hospitals, motor parks, manufacturing firms, to mention a but a few. An interesting aspect of queuing process resides in the measures of its system¿s performance, especially in terms of average service rate, systems, utilization and the costs implied for a given capacity level. One of the expected gains from studying queuing systems is to review the efficiency of the models in terms of utilization and waiting length, hence increasing the number of queues so customers will not have to wait longer when servers are too busy.
