capacity of RP1? What is the maximum processing capacity of each operation?
2) CAPACITY & PROBLEM ANALYSIS
i. CAPACITY ANALYSIS
1. Berries upload to dump
(1) Average truck delivery is 75bbl
(2) Suppose to take 10minutes to each truck.
Each dumps capacity=75(bbl/hr)*6=450(bbl/hr)
(3) Total dumps capacity=450(bbl/hr)*5=2250(bbl/hr)
2. Temporary holding bins capacity
(1) Bins1-16(dr
Capacity & Problem Analysis
I. Capacity Analysis
RP1 was highly mechanized. The process could be classified into several operations : receiving and testing, dumping, temporary holding, destoning, dechaffing, drying, separation, and bulking and bagging. We found major bottleneck on the dryers through NCC flowchart.
First, Bulk trucks carrying process berries arrived at RP1, loading 20
capacity of drying is only 600bbls per hour, the lowest capacity in the process. In other words we need 22.2hr to process all the berries (13,330/600 = 22.2). But, the regular time is only 11hr per day so over time cost for 11.2hr occurs. Therefore, we need more bins to hold the berries waiting to be dried. In current process we can hold 3200bbls temporarily at max (8bins * @250bbls/hr + 3bins *
1) INTRODUCTION
The National Cranberry Cooperative case present the production and operation problems faced by plant processing berries in the USA, in the seventies.
- PRESENTATION OF NCC & THE CRANBERRY INDUSTRY
As volume of the harvested berries increased, problems arose in the transformation of those berries into saleable products. This was the case in NCC’s receiving plant n°1 (RP1).
II. Temporary Holding
After the process berries were weighted, sampled and finally color graded, they were finally moved to one of the five Kiwanee dumpers which had rapidly moving belt conveyors. The berries were taken to one of the 27 temporary holding bins (bins 1-24 held 250 bbls. and bins 25-27 held 400 bbls. each) which were controlled from a central control panel. Although it usually took
