Paperback. Cover has bumped corners and some marks, back cover has remnants of old stickers. Pages throughout are clean and unmarked. Queueing Theory: Worked Examples and Problems is a practical, 88-page educational manual designed to bridge the gap between abstract mathematical theory and real-world industrial application. The book operates on the fundamental principle that random variability in arrival and service times - rather than just average workloads - is the primary cause of system congestion. It teaches readers how to use stochastic modelling to predict queue lengths and waiting times, allowing managers to balance the cost of providing service against the "cost" of customer delay. The book is widely used as a management science training tool for anyone needing to optimise staff scheduling, warehouse flow, or customer service capacity.
