Executive Shirt

Question | Answer |

(A)  Regular Shirts | |

Theoretical CT for Cutting Operation with L of 60 |   0.25 minutes |

Theoretical CT for Cutting Operation with L of 10 |   0.56 minutes |

Labor Content in Cutting per shirt with L = 10 |   2.25 minutes |

Theoretical CT for Process with L = 60 |   0.50 min./shirt |

Daily Process Capacity with L = 60 |   960 shirts |

Average MLT for the process with current rate  of 800 per day -- Minutes | 7056 minutes |

Average MLT for the process with current rate  of 800 per day -- Days | 14.7 days |

Average Labor utilization for the process with current rate of 800/day | 69%  (0.69) |

( C ) Mike’s Plan | |

Daily Capacity of the new ply machine | 960 shirts |

Average MLT for a shirt given 900 shirts per day | 2.2 days |

Average Labor Utilization with current rate of 900/day | 83%  (0.83) |

( D ) Iike’s Plan | |

Daily process capacity for regular shirts | 720 shirts/day |

Daily process capacity for custom shirts | 123 shirts/day |

MLT for custom Line given 100/day | 230.40 minutes |

Labor utilization for Custom Line given 100/day | 34%  (0.34) |

Executive Shirts Company Assignment: Detailed Calculations and Answers

(A)  Regular Shirts:

I.       Current Cutting Operation (Exbt. 2)

         1.   60 layers of cloth (“L=60”)

               Patterns for 8 shirts (8 shirts per layer)

         Cutting takes: (1.5x L + 30) minutes for L layers

         Number of shirts in L layers = 8L shirts 

         (Theoretical)CT for the cutting operation with 60 Layers= 120/480 = 0.25

         Labor content per shirt in the cutting operation:

You could say that the labor content per shirt is 4 x 0.25 = 1 min, because the team of 4persons can cut one shirt every 0.25 minutes.

         2.   Effect of reduced L

               Ex: L = 10

               (Theoretical) CT (for L=10) = 1.5L+30 =1.5*10+30 = 45 minutes / (10*8= 80 shirts)= .5625...
