Smooth Chin Device Company The Smooth Chin Device Company is a manufacturer of high--end electric razors. These razors are produced using a machine--paced process. For each razor, a tray with components enters the process at the beginning of a conveyor belt. The tray then passes through the six steps (consisting of various tasks) explained in the table below. Workers perform the assembly operations on the moving tray. The last step consists of an inspection of the then fully assembled razor. The activity times of the process are as follows: Station Tasks A Preparation 1. Lay out chassis [12 sec] 2. Lay out screws [15 sec] 3. Lay out all other components [17 sec] Total time for A: 44 sec B Assembly 4. Perform task AS1 [10 sec] 5. Perform task AS2 [10 sec] 6. Perform task AS3 [20 sec] Total time for B: 40 sec C Assembly 7.

Smooth Chin Device Company The Smooth Chin Device Company is a manufacturer of high-end electric razors. These razors are produced using a machine-paced process. For each razor, a tray with components enters the process at the beginning of a conveyor belt. The tray then passes through the six steps (consisting of various tasks) explained in the table below. Workers perform the assembly operations on the moving tray. The last step consists of an inspection of the then fully assembled razor. The activity times of the process are as follows: There are six workers, one at each of the six stations (A-F). They begin their workday at 8:00 a.m. and work steadily until 4:00 pm. (They are replaced with other workers for breaks and lunches, but the production is not slowed or stopped during these times.) Their hourly wage rate is $25 per hour. You can assume unlimited demand. What is the process capacity (you can ignore any start-up or empty system effects), in razors/hour?

The process of making a batch of paint in a paint factory consists of the following steps: First, the correct amount of raw materials must be mixed in the proper sequence. The operator must follow specified safety instructions. After mixing, a sample is drawn and taken to a laboratory, where it is tested to ensure conformance to customer requirements a and specifications. Next, the mixing tank is taken to a filling station and verified to be the correct one prior to filling individual cans of paint. The filled cans go to the packing department where labels are printed and applied to the cans. They are inspected to ensure that the labels are correct and the proper quantity was produced for the customers’ order. The cans are packed in boxes and moved to shipping. a. Develop a flowchart that maps out this process. b. Enrich the flowchart by adding detailed steps which may not have been described in detail. c.
