  1. 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

  2. Quiz • Hand draw tonight….Turn next week a printed version sing 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.

  3. 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.

  4. 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.

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.

  6. 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 1-1.5 hrs, act 2B constant 23 hrs (5 glue sta) , act 3 unifm dist 5-10 mins, act 4 is uniform 2-3 hr

  7. 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.

  8. 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.
