- You arrive at the airport and wonder to what extent the security checkpoint is a leanoperation. Among other things, you observe that it takes about 30 seconds to check anID, scan a passenger for weapons, and X-ray their luggage. However, the average customer spends about 20 minutes in the process. This observation is an example of whichof the following?a. Waste of capacityb. Waste of a flow unit’s timec. Waste of materialsd.

The avail-ability of processing per shift, after accounting for breaks anda mid-shift employee meeting, is 436 minutes. The currentoperating characteristics of each processing step are foundin the table below. Note that each step can only processone part at a time and all steps must process the same sizedbatches. a. Calculate the average processing time per unit and thecapacity at each step assuming batch sizes of:i. 10 unitsii. 20 unitsiii. 30 unitsiv. 40 unitsb.

- Sandy is asked to produce 250 squidgets an hour. It takes30 minutes to receive the necessary material from the previous workstation. Each output container holds 25 squidgets.The factory currently works with a safety factor of 10%.How many kanbans should be circulating between Sandy’sprocess and the previous process?arrow_forwardA machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 unties of A and 1,000 units of B. What is the utilization of the machine? answer: _____percentarrow_forwardA machine makes two components; call them types A and B.
