capacity of the dryers is the bottleneck for the wet berries. The maximum throughput for wet berries is 600 bbls/hr. For dry berries the separation process is the bottleneck. The maximum throughput for dry berries is 1200 bbls/hr. The percentage of wet berries to dry berries would affect the throughput rate. Given the current proportion of berries received the capacity of the dryers would be the maximum throughput of the system. The dryers are the system bottleneck. And as the trend of water harvesting

maximized. It doesn’t consider the time and the opportunity cost of utilizing the bottleneck resources. TOC takes into consideration the effect of the most critical resource in finalizing the product mix. It maximizes the product which gives maximum profit on utilizing one unit of the critical resource. In Lehigh’s case‚ Lehigh should not base its product mix decision on either ABC or TOC solely. In the case‚ the bottleneck process of each of the product line is

National Cranberry Cooperative Summary When Hugo Schaeffer‚ vice president of operation at the National Cranberry Cooperative (NCC) went through last fall’s process fruit operation at receiving plant No. 1(RP1) with the superintendent Will Walliston‚ he found that overtime costs and the time waiting to unload were still two big problems. Walliston gave two options to avoid these problems next fall is to buy and install two new dryers‚ and to convert dry berry holding bins so that they can store

The Goal The Goal‚ by Eliyahu Goldratt is a novel focused on the challenges and improvement of operational efficiency. The book is about Alex Rogo‚ a thirty something year old‚ probably has an undergraduate degree in engineering and an MBA. He is married with 2 children‚ working as an executive for UniCo for the past 15 years. He began his career as project engineer‚ now works as a plant manager of manufacturing factory in Bearington‚ his home town. His boss is Bill Peach‚ division manager at the

What is Line Balancing? Line Balancing is leveling of the workload across all operations in a line to remove bottlenecks and excess capacity‚ defined by Six Sigma Material. When you consider mass production‚ garments are produced in lines or set of machines instead of single machine. A line may be assembly line‚ modular line or section‚ a line set with online finishing and packing. A line includes multiple work stations with varied work contents. Production per hour is varied depending on work

To address the wait time issue‚ NCC will need to analyze the plant operations to pin-point the bottlenecks and find ways‚ e.g. redesign the plant‚ invest in resources‚ to reduce these bottlenecks. 2. Draw a process flow diagram for Receiving Plant #1. For each step in the process flow indicate: Following are figures that illustrate the processes within RP1 (from A to F). Figure [ 1 ]:

Report on the book “The Goal” by Eliyahu Goldratt and Jeff Cox I really enjoyed this book. It was easy to read and easy to comprehend. The examples used in the book make the main ideas of the book memorable and easy to understand. I loved how the authors described the thinking process of the main character‚ Alex‚ in a day to day every person’s situations. To me the main value of this book is that its main concepts are applicable to every business‚ not just manufacturing facilities. I work in marketing

CHAPTER FOUR Q4.3. Power Toys (a) Since every resource has exactly one worker assigned to it‚ the bottleneck is the assembly station with the highest processing time (#3) (b) Capacity = 1 / 90 sec = 40 units per hour (c) Direct labor cost = Labor cost per hour / flow rate = 9*$15/h / 40 trucks per hour = $3.38/truck (d) Direct labor cost in work cell= (75+85+90+65+70+55+80+65+80) sec/truck * $15/hr = $2.77/truck (e) Utilization = flow rate / capacity 85 sec / 90 sec = 94.4% (f) (g) Capacity = 1

To our surprise‚ they only have one truck and one driver that delivers all this amount of food. So there lies the bottleneck of this operation: they have enough food to deliver to the clients and enough clients to receive the food‚ but not enough manpower hours and truck space to do all the deliveries within a decent amount of time. Some of the delivery routes can take

Constraint Management at UniCo: Analyzing “The Goal” as Fictional Case Study Abstract As a fictional case study‚ Eliyahu Goldratt’s novel about manufacturing‚ “The Goal: A Process of Ongoing Improvement‚” presents a constraint-focused approach to production management. As a novel‚ the book does not emphasize the quantitative details of the plant improvements. However‚ a great amount of information about the plant is spread throughout the book. By collecting and analyzing this
