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?
A manager wants to assign tasks to workstations as efficiently as possible and achieve an hourlyoutput of four units. The department uses a working time of 56 minutes per hour. Assign the tasksshown in the accompanying precedence diagram (times are in minutes) to workstations using thefollowing rules:a. In order of most following tasks. Tiebreaker: greatest positional weight.b. In order of greatest positional weight. Tiebreaker: most following tasks.c. What is the efficiency?
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

The company thinksthe simplest solution is to obtain two more production lines, thus havingtriple capacity. Another option is to re-balance the line. Considering thata single worker is assigned to a work station, determine which option(more production lines or re-balancing) yields the smallest labour size.arrow_forwardSue Helms Appliances wants to establish an assem-bly line to manufacture its new product, the Micro Popcorn Popper.
