Tailwind, Inc., produces high-quality but expensive training shoes for nmners. The Tailwind shoe, which sells for $210, contains both gas- and liquid-filled compartments to provide morestability and better protection against knee, foot, and back injuries. Manufacturing the shoes requires 10 separate tasks. There are 400 minutes available for manufacturing the shoes in the plant each day. Daily demand is 60. The information for the tasks is as follows: a) Draw the precedence diagram.b) Assign tasks to thl e minimum feasible number of workstations according to the "ranked positioned weight" decision rule.c) What is the efficiency of the process you completed in (b)?d) What is the idle time per cycle?

Assume the company decides to hire additional workers in order to duplicate the bottleneck step identified in part a so that there are 3 of these workstations instead of 1. Redraw the diagram showing the flow of the revised process. Answer parts a through d again based on the new process created in part e?
There is a canteen set up serving food (Breakfast, Lunch, Snacks-tea, and Dinner) to 500 students in a B school. It has a huge well-furnished dining hall and has a serving zone where students queue to pick up their eatables. The Institute director, during his regular Gemba walks in the canteen, has seen a lot of inefficiency in the related operational processes and needs a major improvement. (a)Provide one relatable and relevant example of five of the eight wastes under Lean systems which are likely to be witnessed in the canteen. (b)Recommend lean tools & techniques/system solutions to be employed for curbing each of those five wastes with a line on justification. (c) Suggest three key enablers and measures track the progress on lean in the canteen.
Alocal toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed. The daily demand is 100 toys. Times of the tasks are 2.73, 2.01 201 2.13, 2.0, 2.61, 2.71 , and 2.95 minutes for A,B,C,D,E,F, and respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task Adoes not need any predecessorsB requires task A to completed. To start task C and task Deach require task B to be completed. Task C must be completed prior to stating task E. Task F needs both task D and task Eto be completed. Finally, task G can start only once task Fis completed.Given we apply the most remaining tasks rule for balancing the assembly line with ties broken according to longest task time firstthe tasks that will be assigned to the SECOND workstation are
