- A small, privately owned Asian company is producing a private-label soft drink called Yoggo. A bottling line puts the soft drinks into plastic bottles and then packages the bottles into boxes holding 10 bottles each. The bottling line is comprised of the following four steps: (1) the bottling machine takes 1 second to fill a bottle, (2) the lid machine takes 3 seconds to cover the bottle with a lid, (3) a labeling machine takes 3 seconds per bottle, and (4) the packaging machine takes 4 seconds to place a bottle into a box. When a box has been filled with 10 bottles, a worker tending the packaging machine removes the filled box and replaces it with an empty box. Assume that the time for the worker to remove a filled box and replace it with an empty box is negligible and hence does not affect the capacity of the line. Problem data are summarized in the following table.

- Terex Corporation is a global manufacturer of aerial work platforms and materials processing machinery. They design, build and support products such as large lifting equipment used in construction. The company makes most pieces to order and customizes them to meet customers’ unique preferences.Terex maintained a manual system for yard management at their transfer centre in Washington that is always full of lifting equipment, which generated excessive costs for what should have been a relatively simple process of locating customers’ units to prepare them for delivery. A wallboard and sticker system was a low-tech solution for identifying equipment items in the yard at Terex. While inexpensive in itself, the solution cost around six minutes every time an employee had to locate a unit in the yard. It also required a considerable number of hours to be spent each month taking physical inventories. After a successful pilot, the company approved a new solution, replacing stickers, yard maps,…Terex Corporation is a global manufacturer of aerial work platforms and materials processing machinery.

- . Aquatica makes underwater camera housings for divers. The process begins with a solid rectangular block of aluminum that is used to make a single housing. A computer numerically controlled (CNC) machine drills into the block to make the metal “frame” of the housing. Each block requires 15 minutes of drilling. The frame is then chemically treated in a series of baths. There is ample capacity in the treating stage. Finally, a worker must manually attach the various buttons and components to the metal housing. This assembly takes 120 minutes per housing per worker and Aquatica has 6 workers trained to do this task. The CNC machine requires a 30-minute setup time before the production of a batch can begin. a. If the CNC machine produces 14 housings between setups, what would be its capacity (in housings per hour)? b. Assuming the process is supply-constrained, what is the utilization (as a number between 0 and 1) of the CNC machine if it operates in batches of 14 housings? c. Assuming…An average of 1200 parts arrive to the EP chamber during an 8-hour workday. Each part goes through two stages of processing. At each stage, a single product is processed at a time, and processing takes an average of 15 seconds at the first station and 12 seconds at the second station. Inter-arrival times and service times are exponentially distributed. At the end of the second step, the product goes through a quality check. 5% of the parts fail the quality check and are sent back to the second stage of service. Parts exit the system only after they pass the quality check. Ignoring the time required to perform the quality check or in moving the part through the facility, what is the average cycle time for parts?Teddy Fields is the Kitchen Manager at the Tanron Corporation International Headquarters. The facility he helps manage serves 3000 employees per day. Teddy very much needs an additional dishwasher, and is interviewing Wayne, an excellent candidate with 5 years experience who is now washing dishes at the Roadway restaurant. Teddy normally starts his dishwashers at $12.00 per hour. Wayne states that he makes $13.00 per hour, a rate that is higher than all but one of Teddy’s current dishwashers. Wayne states that he would not leave his current job to take a “pay-cut”. Should Teddy offer to hire Wayne at a rate higher than most of his current employees? Why or why not?
- One of the chair lifts at a ski resort unloads 1800 skiers per hour at the top of the slope.The ride from the bottom to the top takes 12 minutes. How many skiers are riding onthe lift at any given time?A 10 station automated assembly system produces an ideal cycle time (Tc) of 14 seconds/cycle. When a defective part enters any assembly station it sometimes causes a station jam or stoppage. Defective parts occur at a rate of 0.07 and a jams due to defective parts occur at a rate of 0.4. When a jam occurs, it takes on average 74 seconds to clear and restart the station. Determine the production rate of acceptable parts (Rap) to the nearest 1 part/hour.12-15 The wheat harvesting season in the American Midwest is short, and most farmers deliver their truckloads of wheat to a giant central storage bin within a two-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer’s benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays, the cost of truck rental, and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $18 per hour. The storage bin is open and operated 16 hours per day, 7 days per week, during the harvest season and is capable of unloading 35 trucks per hour according to an exponential distribution. Full trucks arrive all day long (during the hours…
