3. Introduction  Goal:  Understand how OR contributes in solving some industrial problems characterized by the stochastic conditions  Outcome:  Enable to model some stochastic situations  Enable to solve some stochastic model  Understand the basic of simulation

4. Why concern on stochastic?  Some facts:  Shop-floor condition is seldom stable for more than half an hour (McKay et al, 1995)  We can never predict demand for a product accurately  Although preventive maintenance is done, we can never eliminate the occurrence of machine breakdown  Due to the process variability, the processing time is seldom constant  etc  The only certainty in the real world is uncertainty

5. Course outline Inventory models Queuing theory Introduction to stochastic process Continuous Time Markov Chain Discrete Time Markov Chain Exponential distribution and poison process Introduction to simulation Generating random number and random variates
