Q vs Await Node
• Q is a simplified Await node
• Q activity is the resource ie server, inspection
• Await Node can specify resource that is needed by activity ie tools, parts, materials, etc

Quiz
• Hand draw tonight….Turn next week a printed version using AweSim software, a single server operation of a 7-11 store using AweSim objects, customers arrive at the counter that is Exponentially distributed with a mean of 4.5 minutes, the duration of the service time is normally distributed with a mean of 3.2 minutes and a standard deviation of 0.6 minutes, end the simulation after 1000 customers.

• AweSim software, a single server operation of a 7-11 store using AweSim objects, customers arrive at the counter that is Exponentially distributed with a mean of 4.5 minutes, the duration of the service time is normally distributed with a mean of 3.2 minutes and a standard deviation of 0.6 minutes, end the
simulation after 1000 customers. Use Q
Use Await

ExercisesDue Monday 10/29
• 6-9 Machine tool processes 2 diff parts. T1 arrival time is tri dis 20-30-50. Interarrival time of T2 tri dis 35-50-60. Processing time for T1 is exp, m=20, T2 uniform min 15- max 20. Processing includes inspection, 1% fail, return to que the rework time =90% of original. Find time in system of part & utilization of machine. Use create/ await/ a conditional split of activities/ free/ collect/ terminate.

Series/ parallel process example
• Build picture frames. 4 activities: cut mtl, glue frames, sand, finish. How long will it take to build each frame?, Show in histogram for case1 & 2.
• Case one: all series activity 1 is unifm dist 1 to 2mins, act 2 is constant 24 hrs, act 3 unifm dist 5-10 mins, act 4 is uniform 2-3 hr• case two: activity 1 is unifm dist 1 to 2mins, act 2A is unifrm 0.5-1.0 hrs, act 2B constant 23 hrs (5 glue sta) , act 3 unifm dist 5-10
mins, act 4 is uniform 2-3 hr

Bank example
• 2 inside tellers & 2 drive up tellers, time bwtn arrivals of outside tellers is is expon dist m=.75mins. Limited waiting space for drive up one is 3 cars and drive up 2 4 cars. Service time drive up one is norm dist 5 mins, dev = 1 min, 2nd drive up service time is uniform btwn 4 & 5 mins. If car arrives at drive up and line is full, the customer will go inside. Other walk in customers arrive at a rate of expon = .8 mins. They join a single Q and service time for both inside is triangular 2,3,5 dist., this line will only hold 7.
