National Cranberry Cooperative
Please read the course pack item “National Cranberry Cooperative”. The assignment is composed by two parts, which are due on different day. The following are the common assumptions for both Part I and Part II
A. All the processes (including Destone, Dechaff, and Dry) start from 7am.
B. On an average “busy” day, there are 18,000 bbls delivered over 12-hour period (from 7am to 7pm).
C. Wet berries are 70% of all berries.
D. Holding bins 17-24 are dedicated to wet berries.
E. Capacity of each of five dumpers is 600 bbl/hr.
F. Capacity for Dechaffers is not divided for dry and wet berries.
Part I
Specific assumption for Part I:
1(a) Capacity for separators is not divided for dry and wet berries.
Please prepare the answers to the following questions:
1. Analyze the current process. [Using the process flow map, available in the Excel file associated with the assignment, of the current process at Receiving Plant #1, mark the capacity and utilization of each of the operations. Show the flows of wet and dry berries separately.]
In excel.
2. On a busy day, what is RP#1’s current maximum throughput rate?
Throughput rate = the minimum of capacity rate and demand rate = Inventory / Flow time = 450 bbls/hr * 12 = 5400 bbls/day
3. Assuming that processing starts at 7 am on a “busy” day, present the situation during such a day, by constructing an inventory build-up diagram for bins and trucks.
Requirements:
Please submit one copy of written report through eCampus by 13:45, 09/29/2014.
Please clearly itemize your responses to specific questions.
Please briefly show the steps how you get the solutions.
Part II
Specific assumptions for Part II:
2(a) There are 20 peak days in one year, during which there is truck waiting happened.
2(b) Truck Drivers are paid by $18/hr
2(c) Two lines of separators are for wet berries and one line for dry berries.
