Lab 2 of 6: Theory of Constraints
Submit your assignment to the Dropbox located on the silver tab at the top of this page.
(See the Syllabus section “Due Dates for Assignments & Exams” for due dates.)
This Lab looks at bottlenecks and the calculations necessary to determine which process is the source of a bottleneck condition. Use MS Word to copy your answers.
|Theory of Constraints Lab||Points||Description|
|Shaping||9||Determine the setup, run time, and total time for the Shaping Department.|
|Pickling||9||Determine the setup, run time, and total time for the Pickling Department.|
|Packing||9||Determine the setup, run time, and total time for the Packing Department.|
|Bottleneck||8||Determine which department is the bottleneck for this production operation.|
|Total||35||A quality paper will meet the above requirements.|
Scenario and Summary
Situation: Maruchek’s makeshift manufacturing facility has three departments: shaping, pickling, and packing. Maruchek’s orders average 100 pieces per order.
Each of the three shaping machines requires 1 hour to set up and can run one piece per minute.
The pickling department lowers baskets into brine tanks and subjects them to low-voltage current, heating and cooling, and a rinse. The whole process takes four hours for any number of baskets or pieces. One brine tank is available, and it is capable of processing four baskets at one time. Each basket can hold 50 pieces. Baskets are loaded while a load is being processed in the tank.
Each piece is inspected and wrapped in bubble pack in the packing department. Each of the four people in the department can do this at the rate of 25 pieces per hour.
Maruchek has heard of optimized production technology (OPT) and wants to identify the bottleneck in his department.
Assume you have enough labor to set up all of the shaping machines at the same time.
Determine the process requirements for the three departments and identify which department is a bottleneck. Submit your answer in an MS Word document.
STEP 1: Shaping
Determine the setup, run time, and total time for the Shaping Department. Copy your answer to an MS Word document.
STEP 2: Pickling
Determine the setup, run time, and total time for the Pickling Department. Copy your answer to an MS Word document.
STEP 3: Packing
Determine the setup, run time, and total time for the Packing Department. Copy your answer to an MS Word document.
STEP 4: Bottleneck
Determine which department is the bottleneck for this production operation. Remember that it often helps to understand the relationship of the different processes by putting everything in a nice, neat table like we did last week.
Copy your answer into an MS Word document.
STEP 5: Submission of Your Assignment
Submit your completed Lab in an MS Word document for grading. Please provide onlyone document with all responses.
