The capacity of dressing is the lowest of all. Hence, it will be the capacity of the process.
The capacity of the process is 200 units per hour.
b)
To determine: The utilization of depositing for 800 dolls.
b)
Explanation of Solution
Given information:
Capacity of Molding:
Capacity of painting:
Capacity of dressing:
Calculation of utilization of molding:
The flow rate is the minimum demand and process capacity. The capacity of the process is 200 units per hour. The demand is 4,000 dolls in 40 work hours which gives 100 dolls per hour. Therefore, the number of dolls per minute will be:
The flow rate is 1.67 dolls per minute.
Calculation of utilization:
The utilization of molding is 41.75%.
c)
To determine: The determine the batch size that would minimize the inventory without decreasing the flow rate.
c)
Explanation of Solution
Given information:
Calculation of batch size for molding:

- Hammond Inc. has analyzed the setup time on its computer-controlled lathe. The setup requires changing the type of fixture that holds a part. The average setup time has been 135 minutes, consisting of the following steps: Step Time (in minutes) Turn off machine and remove fixture from lathe 13 Go to tool room with fixture 15 Record replacement of fixture to tool room 18 Return to lathe 20 Clean lathe 17 Return to tool room 20 Record withdrawal of new fixture from tool room 12 Return to lathe 15 Install new fixture and turn on machine 8 Total setup time 138 Why should management be concerned about improving setup time? What do you recommend to Hammond Inc. for improving setup time? How much time would be required for a setup, using your suggestion in (b)?arrow_forwardTwo 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 explainarrow_forwardA catalog order-filling process can be described as follows:12 Telephone orders are taken over a 12-hour period each day. Orders are collected from each person at the end of the day and checked for errors by the supervisor of the phone department, usually the following morning. The supervisor does not send each one-day batch of orders to the data processing department until after 1:00 p.m. In the next step—data processing—orders are invoiced in the one-day batches. Then they are printed and matched back to the original orders. At this point, if the order is from a new customer, it is sent to the person who did the customer verification and setup of new customer accounts. This process must be completed before the order can be invoiced. The next step—order verification and proofreading—occurs after invoicing is completed. The orders, with invoices attached, are given to a person who verifies that all required information is present and correct to permit typesetting. If the verifier has…arrow_forward
- Quasi-Tech Corporation produces specially machined parts. The parts are produced in batches in one continuous manufacturing process. Each part is custom produced and requires special engineering design activity (based on customer specifications). Once the design is completed, the equipment can be set up for batch production. Once the batch is completed, a sample is taken and inspected to see if the parts are within the tolerances allowed. Thus, the manufacturing process has four activities: engineering, setups, machining, and inspecting. Costs have been assigned to each activity using direct tracing and resource drivers as follows: Activity Expected Cost Activity Driver Activity Capacity Engineering $1,000,000 Engineering hours 5,000 hours Setups 900,000 Setups 200 setups Machining 2,000,000 Machine hours 25,000 machine hours Inspection 800,000 Inspection hours 2,500 inspection hours Quasi-Tech produces two models: Model C and Model D.

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…arrow_forwardA startup company is considering making a part by injection molding. The part is moderately complex and the volume of the part is about 10 cubic centimeters. Assume that the part is designed for injection molding and can be made with a two part mold. The company needs to make 250,000 parts made from ABS plastic. Once the mold is made it will take a worker 1 minute to make one part using the injection molding machine. The company will use contract manufacturing to produce the parts. Estimate the cost per part and explain how you came up with the number. (If you are stuck look at the Contract Manufacturing Cost per Unit section. Also keep in mind that there is no exact right answer, the goal is to come up with a reasonable estimate.) Contract Manufacturing Cost per Unit: It’s not uncommon to hire another company to perform some or all the manufacturing for a product. To estimate the cost use ((Cost of Parts and Materials) + (man hours) × $40)/.75arrow_forward
- It takes Carissa 45 minutes to finish a 60-ietm test in math. At this rate, how many minutes will it take her to finish a 120-item test?arrow_forwardA 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). 6 units/hr Sawing 2.5 units/hr Sanding Drilling 1.8 units/hr Welding 7 units/hr Assembly 0.7 units/hr Assembly 0.7 units/hr Assembly 0.7 units/hrarrow_forward. 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…arrow_forward
