Chapter 4.12, Problem 8P
As technology advances and new materials are synthesized, there are certain products that receive only minimal, if any, modernization attempts. Among them are the shopping carts used in grocery stores. There is a tendency to save parking spaces by not designating a return cart area. Leaving carts in the parking lots may lead to serious accidents and car damage. Furthermore, although many customers do not fill their carts that much when t shopping, they do not like to carry baskets. Other customers like to sort products as they shop. Develop an objective tree to clarify the need statement and prioritize the objectives laid out in the problem statement. You may add features that may not be listed clearly in the problem statement but will give an additional advantage to the proposed design.

The production department for a company
requires 3500kg, of row material for
manufacturing a particular item per year. It
has been estimated that the cost of placing
an order is Rs.35 & the cost of carrying
inventory is 25 percentage of the investment
the inventories. The price is Rs.10 per kg. The

ordering policy for raw material. Calculate (1)
The optimal lot size (2) The minimum yearly
variable inventory cost (3) The optimal order
cycle time (4) The minimum yearly total
inventory cost.

1. Specialization and production possibilities
Suppose Spain produces only tablets and smartphones. The resources that are used in the production of these two goods are not specialized-that is,
dy Tools
the same set of resources is equally useful in producing both smartphones and tablets.
The shape of Spain's production possibilities frontier (PPF) should reflect the fact that as Spain produces more smartphones and fewer tablets, the
opportunity cost of producing each additional smartphone

- A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through ten machines in batch sizes of one. The shop contains a total of eight conventional machine tools and operates 40 hours per week of production time. Average time values on each part per machine are: Machining time = 0.5 hour; Work handling time = 0.3 hour; Tool change time = 0.2 hour; Setup time = 3 hours; Nonoperation time = 12 hours. A new programmable machine is being considered that can perform all ten operations in a single setup. The programming of the machine for this part will require 20 hours; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hours because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work handling time will be the same as for one machine; and total tool change time…arrow_forwardMost of the CTDS representing Engineering products are: 3-levels. 2-levels. 4-levels. 5-levels.arrow_forwardSuppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost).
