Gilbert Moss and Angela Pasaic spent several summers during
their college years working at archaeological sites in the
Southwest. While at those digs, they learned how to make ceramic
tiles from local artisans. After college they made use of their
college experiences to start a tile manufacturing firm called
Mossaic Tiles, Ltd. They opened their plant in New Mexico, where
they would have convenient access to a special clay they intend to
use to make a clay derivative for their tiles. Their manufacturing
operation consists of a few relatively simple but precarious steps,
including molding the tiles, baking, and glazing. Gilbert and
Angela plan to produce two basic types of tile for use in home
bathrooms, kitchens, sunrooms, and laundry rooms. The two types of
tile are a larger, single-colored tile and a smaller, patterned
tile. In the manufacturing process, the color or pattern is added
before a tile is glazed. Either a single color is sprayed over the
top of a baked set of tiles or a stenciled pattern is sprayed on
the top of a baked set of tiles. The tiles are produced in batches
of 100. The first step is to pour the clay derivative into
specially constructed molds. It takes 18 minutes to mold a batch of
100 larger tiles and 15 minutes to build a mold for a batch of 100
smaller tiles. The company has 60 hours available each week for
molding. After the tiles are molded, they are baked in a kiln: 0.27
hour for a batch of 100 larger tiles and 0.58 hour for a batch of
100 smaller tiles. The company has 105 hours available each week
for baking. After baking, the tiles are either colored or patterned
and glazed. This process takes 0.16 hour for a batch of 100 larger
tiles and 0.20 hour for a batch of 100 smaller tiles. Forty hours
are available each week for the glazing process. Each batch of 100
large tiles requires 32.8 pounds of the clay derivative to produce,
whereas each batch of smaller tiles requires 20 pounds. The company
has 6,000 pounds of the clay derivative available each week.
Mossaic Tiles earns a profit of $190 for each batch of 100 of the
larger tiles and $240 for each batch of 100 smaller patterned
tiles. Angela and Gilbert want to know how many batches of each
type of tile to produce each week to maximize profit. In addition,
they have some questions about resource usage they would like
answered.
k. The kiln for glazing had to be shut down for 3 hours, reducing the available kiln hours from 40 to 37. What effect will this have on the solution? l. What are the reduced costs for larger and smaller tiles? Explain.
I don’t know how to do part l

Crank Ltd Crank has been in business since the 1920’s and have three locations in the UK. Their Head Office and main manufacturing site is in Leicester. This site makes complex tubular assemblies for defence organisations, oil and gas and transportation. There is a site at Southampton making tubular shafts for golf clubs, and a site in Glasgow manufacturing aerospace Duct assemblies up to 8″ diameter. The procurement organisation is currently decentralised. At Leicester, there is a Purchasing Manager, whereas at Southampton and Glasgow, each site has a Chief Buyer in charge of small procurement teams. There is a new Chief Executive of Crank who fervently believes that he needs a new approach for the Group in the way procurement is structured. Over the past month, he has, quietly, been obtaining some salient facts.
The more important ones are
• Each site operates as a ‘Profit Centre’ and the Site Director has to deliver a targeted Return on Capital Employed;
• There are no Group purchase contracts;
• Five major purchases account for 61% of total Group expenditure – they are all raw material including different specifications of tubing;
• There are more than 40 suppliers for the five major purchases; • No formal tendering has taken place, on any site, for more than two years;
• Capital equipment is purchased by the Group Chief Engineer;
• The company has embraced modern logistics practices including JIT and OTIF (On Time In Full);
• There is no savings plan for purchasing;
• The purchasing teams do not liaise.
The Chief Executive intends to consider an alternative purchasing structure that can deliver benefits for the Group and each operational site. On the basis of your knowledge and the salient facts above what advice could you give him?
