- A dress-making operation is being designed as an assemblyline. Table 10-22 shows the tasks that need to be performed, theirtask times, and preceding tasks. If the goal is to produce 30 dressesper hour, answer the questions that follow the table. (a) Compute the cycle time.(b) Which task is the bottleneck?(c) What is the maximum output for this line?(d) Compute the theoretical minimum number of stations.(e) Assign work elements to stations, using the longest tasktime rule.(f) Compute the effi ciency and balance delay of yourassignment.A production schedule requires six work stations. However, there are nine work tasks to be performed to produce a unit of output. The warchouse is operated for seven days a week and three 8-hour shifts per day. The desired output per week is 1.728 units. The tasks, precedence relationships and the approximate amount of time required to carry out cach task is presented below.

What is the theoretical number of workstations required to meet the desired output rate? (Round up yo number.) Task C D E, F d. Balance the line using sequential restrictions and the longest-operating-time rule. (Leave no cells blar wherever required. Round your answers to 1 decimal place.) Idle TimeThree departments- milling (M), drilling (D), andsawing (S)- are assigned to three work areas in Victor Berardis'smachine shop in Kent, Ohio. The number of workpieces movedper day and the distances between the centers of the work areas,in feet, follow. Pieces Moved between Work Areas Each Day lt costs $2 to move I workpiece I foot.What is the cost?(a) What is the cycle time necessary to achieve the desired rate of production?(b) Using the longest element rule, create workstations to balance the line,attempting to get as close as possible to the theoretical minimum numberof workstations.(c) What is the efficiency and idle time of the line balance?(d) The company considers that if the lamps are successful with the publicit may need to increase production to 30,000 units. 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.
