Assuming that the arrival rate is greater than five customers per hour, when would you expect Type A customers to experience waiting lines, assuming no Type B customers in the shop? A. Steps T3 and T4. B. Steps T1, T2, and T4. C. Steps T1, T2, T3, and T4. D. Step T3 only.
The following flow chart shows the entire manufacturing process at KD Manufacturing, which consists of six independent operations processes (i.e. sawing, sanding, drilling, reshaping, welding, and assembly). The entire process flow starts with the input of three different parts, Part I, Part II and Part III, each entering a different input line. Three parts meet later for the welding, whichever welding station is available (two identical welding stations work independently). After welding is completed, the product is sent to one of the three assembly stations (which are in parallel). The chart also shows the processing time per unit (in minutes) for each operation. Each of sawing, sanding, drilling and reshaping stations is handled by a different worker. Two workers handle welding, each at one welding station. Another three workers handle the assembly process independently, one at each assembly station. To improve the capacity of the entire manufacturing process, the manager decides to…
Bill’s Barbershop has two barbers available to cut customers’ hair. Both barbers provide roughly the same experience and skill, but one is just a little bit slower than the other. The process flow in Figure shows that all customers go through steps B1 and B2 and then can be served at either of the two barbers at step B3. The process ends for all customers at step B4. The numbers in parentheses indicate the minutes it takes that activity to process a customer.a. How long does it take the average customer to complete this process?b. What single activity is the bottleneck for the entire process?c. How many customers can this process serve in an hour?

Rocky’s Pre-Cast Shop is considering two different processes for completing Pre-Cast jobs. Process A uses one person to setup the job and do the pre-casting. If this approach is used, an experienced person can complete an average of 20 jobs per day. Process B uses two people. One person does the setup and the second person does the actual pre-casting. Setup on one job can be done while pre-casting is being completed on another but pre-casting must be completed on a job before the pre-cast machine can start processing the next. After some practice, this second process can be completed with a standard time of 10 minutes for setup and 15 minutes for actual pre-casting. In either case, assume an 8-hour day, 5 days per week, 250 days per year. 3. Assuming ideal conditions, what is the maximum capacity of process B? 4. How long would it take to process 200 jobs using process A (assume only one worker and one machine)? 5. If Rocky’s is primarily…
