Matrix product planning

Quality function deployment (QFD), also referred to as customer driven engineering and matrix product planning , is a useful quality and planning tool which uses a structured approach in defining all the customer needs or requirements and translates these into design requirements for product development. 

The general SCM matrix can be adapted to better reflect the specihc characteristics of basic chemical industry. In the traditional SC planning matrix, the material requirement planning modules are concerned with determining order quantities of raw and intermediate materials necessary to realize a pre-dehned production plan. These tasks are particularly challenging if the variety of handled materials is large.In basic chemical industry, however, the variety of raw and intermediate chemicals is comparatively small while their demand is high and mostly determined by the plants technical specifications. 

Carbonate rocks are more frequently fractured than sandstones. In many cases open fractures in carbonate reservoirs provide high porosity / high permeability path ways for hydrocarbon production. The fractures will be continuously re-charged from the tight (low permeable) rock matrix. During field development, wells need to be planned to intersect as many natural fractures as possible, e.g. by drilling horizontal wells. 

New product development programs present another type of challenge to the researcher. Often the researcher has no guidelines for evaluating the new product and must formulate a unique plan for developiag enough iaformation to constmct a matrix that would show the risks and rewards of the project. Reference 6 presents 10 commandments for new-product development. 

The design verification plan should be constructed so that every design requirement is verified and the simplest way of confirming this is to produce a verification matrix of requirement against verification methods. You need to cover all the requirements, those that can be verified by test, by inspection, by analysis, by simulation or demonstration, or simply by validation of product records. For those requirements to be verified by test, a test specification will need to be produced. The test specification should specify which characteristics are to be measured in terms of parameters and limits and the conditions under which they are to be measured. 

As the war drew to a close, Owens-Corning began to plan for peacetime uses of its fiberglass products. In 1946, it introduced fiberglass-reinforced fishing rods, serving trays, acoustical tiles, and pleasure boats. And in 1953, it announced production of the first commercial automobile, the Chevrolet Corvette, with a body made entirely of polymer matrix composite, a fiberglass reinforced plastic.

The main given parameters are a) the pipeline volume, b) maximum and minimum flowrates, c) the products to be pumped and matrix of possible sequences, d) the tanks capacity and product s service, e) settling period by product and as scenario data f) the time horizon extent and number of days, g) the maximum number of batches to be pumped, h) the initial inventory by product and by tank, i) the state of each tank and the initial settling time of each tank (if applicable, otherwise set to zero), j) the daily clients demands and k) the planned pipeline stoppages, if any. 

Testing Who develops test plans Are requirement specifications reviews and design inspections done periodically How is functional testing performed Who is testing (outside the development department) Are there test protocols Is there a test traceability matrix to ensure that all user requirements and product functions are tested Are there procedures for recording, storing and auditing test results Who approves test plans/protocols ... 

Other tools QFD is typically a jumping-off point for a new product or other major change. Often QFD wiU establish the need for planned experimentation or customer surveys. Mechanics Create a matrix enter quality characteristics on one side. Enter process choices on the other side weight the effects. Identify interrelationships. Note where tests and new information are needed. 

The input-output (10) analysis model was invented by Wassily Leontief who was awarded the Nobel Prize in 1973. The 10 model is a general equilibrium model of an economy showing the extent to which each sector uses inputs from the other sectors to produce its output, and thus showing how much each sector sells to each other sector. The lO model shows the increase in economic activity in every other sector that would be required to increase the net production of a sector by, for example, 1 million. In the case of 1 million worth of paint required for corrosion prevention, the 10 model would show the total activity in all sectors would amount to the 1 million worth of paint. The lO matrix was constructed by the U.S. Department of Commerce on the basis of the census of manufacturers in 1973 and represents the actual structure of the U.S. economy at that time. The 10 model has been very invaluable for planning. The 10 framework has also been useful in estimating the total economic activity that will result from net additional purchases from a sector and the total economic loss because of closure of an industry.
