A machine shop manufactures two types of bolts. The bolts require time on each of the three groups of machines, but the time required on each group differs, as shown in the table below. Type I Type II Machine 1 0.2 min 0.2 min Machine 2 0.6 min 0.2 min Machine 3 0.04 min. 0.08 min Production schedules are made up one day at a time. In a day, 300, 720, and 100 minutes are available, respectively, on these machines. Type I bolts sell for 15¢ and type II bolts for 20¢. (a) How many of each type of bolt should be manufactured per day to maximize revenue? (b) What is the maximum revenue? (c) Suppose the selling price of type I bolts began to increase. Beyond what amount would this price have to increase before a different number of each type of bolts should be produced to maximize revenue?

Consider the following batch-flow process consisting of three process stepsperformed by three machines. Process steps step 1 step 2 step 3 processing time 0.25min./unit 0.20 min./unit 0.15 min./unit setup time 30 min 20 min 45 min Work is processed in batches at each step. Before a batch is processed at a step, the machine atthat step must be set up. (During a setup, the machine is unable to process any product.) Assumethat there is a dedicated setup operator for each machine (i.e., there is always someone availableto perform a setup at each machine.)a. What is the capacity of step 1 if the batch size is 35 parts?b. For what batch sizes is step 1 (2, 3) the bottleneck?

Sassy Ko is the loading dock supervisor for a dry cement packaging company. His work crew is comprised of unskilled workers who load large transport trucks with bags of cement, gravel and sand. The work is hard and the employee turnover rate is high. Employees record their attendance on separate timecards. Sassy Ko authorizes payroll payments each week by signing the timecards and submitting them to the payroll department. The paychecks are then prepared by payroll and distributed to Sassy KO, who distributes them to his work crew. a) Identify any control problems in the system. b) What sorts of frauds are possible in this system?

Two vital stages in a production process are assembly I and assembly II. The unit load for the assembly I stage is 7.0 ( 50% higher for high skill) minutes, while it is 10.0 (30 % higher for high skill) minutes for assembly II. There are 7 employees working in assembly I and 8 employees working in assembly II. 65% of low skill labor and 35% of high skill labor are required at both stages. . On average 18% of the operating time is wasted, what's the theoretical unit load for Assembly II? answer is 9.06 please explain
. 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…

A local bakery is renowned for its elaborately cecorated sheet cakes. Consider the following process information: One baker is ivailable to prepare the cake batter (measuring and mixing ingredients and then adding it to baking pans). On average, this takes 10 minutes to prepare two cakes, ie. to make enough batter for 2 cakes and to add the batter to 2 cake pans. Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day. Answer each of the following questions: a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating? b. What is the dally process capacity? Explain. c. If orders arrive at a rate of 3 cakes every 20 minutes, can the bakery meet the caily demand Explain, Note: Be clear about how you…
A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). 7 units/hr 5 units/hr Assembly 0.8 units/hr Sawing Sanding Welding Assembly 2.1 units/hr 0.8 units/hr Drilling 2.5 units/hr Assembly 0.8 units/hr a) is the bottleneck. b) The bottleneck time is minutes per unit (round your response to two decimal places). c) The throughput time of the overall system is minutes (round your response to two decimal places).
The OR is available for 12 hours a day; the hospital has decided to not perform any procedures between 7pm and 7am. This time is equally divided across three surgeons. The standard procedure time for the knee surgery done at the clinic is 1h. The cleaning and housekeeping that needs to happen after each procedure takes 20 minutes. Almost all of this time could be saved if the cleaning crew were notified earlier on. 10 minutes are spent on patient preparation / anesthesia work before each procedure. (Note: this is not part of the 60-minute procedure time). Proposals have been evaluated to move these 10 minutes to outside the OR, and there exists no medical reason that would prohibit doing this.) A surgeon only starts a case if all of the work associated with the case (preparation, procedure, and cleaning) can be completed in the 4h allotted to each surgeon. Surgeons never start BEFORE their allotted time. Though the clinic aims to operate 7 days a week, holidays, vacation, and…
Chairs are made in a process with a single resource. There are two types of chairs. The resource's processing time for the first type is 30 minutes and demand for this type is 2.3 chairs per hour.
