Balance the assembly line shown below for (a) a shift output of 60 pieces and (b) a shift output of 40 pieces. Assume an 8-hour shift, and use the rule: choose the assignable task with the longest processing time. Compute the line efficiency for each case. Fill in the table below for a shift output of 60 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number.

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?

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.

A linear programming computer package is needed. EZ-Windows, Inc., manufactures replacement windows for the home remodeling business. In January, the company produced 15,000 windows and ended the month with 9,000 windows in inventory. EZ-Windows' management team would like to develop a production schedule for the next three months. A smooth production schedule is obviously desirable because it maintains the current workforce and provides a similar month-to-month operation. However, given the sales forecasts, the production capacities, and the storage capabilities as shown, the management team does not think a smooth production schedule with the same production quantity each month possible.
