Marilyn Hart, operations manager at Hart Electronics,faces assembly-line balancing problems. She has been told thatthe firm needs to complete I ,400 electronic relays per day. Thereare 420 minutes of productive time in each working day (which isequivalent to 25,200 seconds). Group the assembly-line activitiesin the following table into appropriate workstations and calculatethe efficiency of the balance.
Management wants to design an assembly line that will turn out 800 videotapes per day. There will be eight working hours in each day. The industrial engineering staff has assembled the information below: A) Determine the maximum and minimum cycle times.B) Determine the optimum cycle time.C) What is the minimum number of stations needed?D) Draw the precedence diagram.E) Assign tasks to stations in order of most following tasks first. Submit an Excel file based on Chapter 6 Excel Template to indicate your computation.
A paced assembly line has been devised to manufacture calculators, as the following data show:
