Product development. See

The examples above demonstrate the impact of the percolation theory in developing scientiLc network to build the knowledge pyramid for product development (see Figure 20.2). 

For an interesting case of data fabrication and falsification in macro-engineering product development, see Vandivier (1972). 

Product development can be defined as the transformation of a market opportunity into a product available for sale (Krishnan and Ulrich, 2001). The actual process that underlies this transformation is often decomposed into five phases concept development, system-level design, detailed design, testing and refinement, and production ramp-up (Ulrich and Eppinger, 1995). Each of these involves a series of dynamic decisions and can evolve over time in an iterative fashion. For recent literature reviews of research on product development see Krishnan and Ulrich, 2001, Ozer, 1999, and Wind and Mahajan, 1997. 

Such as Albach (1993), Albach et al. (1989), Steenkamp et al. (1999), Herbig, Palumbo (1994). More authors, however, study the relationship between culture and new product development, see e.g. Nakata, Sivakumar (1996) for a review. 

With the extensive knowledge available in oil chemistry, development of designer fats and oils is possible (34). This is of special interest to nutritionists who see the possibiUties for stmcturaHy designed fats to meet developing knowledge in clinical nutrition and food product development. 

The most widely used process for the production of phenol is the cumene process developed and Hcensed in the United States by AHiedSignal (formerly AHied Chemical Corp.). Benzene is alkylated with propylene to produce cumene (isopropylbenzene), which is oxidized by air over a catalyst to produce cumene hydroperoxide (CHP). With acid catalysis, CHP undergoes controUed decomposition to produce phenol and acetone a-methylstyrene and acetophenone are the by-products (12) (see Cumene Phenol). Other commercial processes for making phenol include the Raschig process, using chlorobenzene as the starting material, and the toluene process, via a benzoic acid intermediate. In the United States, 35-40% of the phenol produced is used for phenoHc resins. 

Quaternized Esteramines. Esterquatemary ammonium compounds or esterquats can be formulated into products that have good shelf stabihty (209). Many examples of this type of molecule have been developed (see Fig. 1). 

The so-called Q7 tools and techniques, Cause and Effect Diagrams, Pareto Analysis, etc. (Bicheno, 1994 Dale and McQuater, 1998 Straker, 1995), are applicable to any stage of the product development process. Indeed they support the working of some of the techniques mentioned, for example using a Pareto chart for prioritizing the potential risks in terms of the RPN index for a design as determined in FMEA (see Appendix III). 

Many different types of models may be produced to aid product development, test theories, experiment with solutions, etc. However, when the design is complete, prototype models representative in all their physical and functional characteristics to the production models may need to be produced. When building prototypes, the same materials, locations, subcontractors, tooling, and processes should be used as will be used in actual production so as to minimize the variation (see also clause 4.4.8.3). 

The standard provides a choice as to whether you define the inspections and tests required in a quality plan or in documented procedures. You may of course need to do both. As the quality system is often designed to accommodate all products and services you supply, it may not specify inspections and tests which are needed for particular products. This is one of the roles of the quality plan. Within such a plan you should identify the verification stages during product development, production, installation, and servicing as applicable. These stages will vary depending on the product, so your quality plan will be product, contract, or project specific (see Part 2 Chapter 2). There may... 

The noteworthy successes of a relevant model study12 provided the foundation for Merck s thienamycin syntheses. In the first approach (see Schemes 2 and 3), the journey to the natural product commences from a readily available derivative of aspartic acid this route furnishes thienamycin in its naturally occurring enantiomeric form, and is noted for its convergency. During the course of this elegant synthesis, an equally impressive path to thienamycin was under parallel development (see Schemes 4 and 5). This operationally simple route is very efficient (>10% overall yield), and is well suited for the production of racemic thienamycin on a commercial scale.. x... 

The basic regulatory strategy employed to safeguard public health relies on focussing attention on three main areas of activity product development product manufacture and market vigilance (see Figure 2.1). 

Rinard dedicated his research to a detailed analysis of methodological aspects of a micro-reactor plant concept which he also termed mini-plant production [85] (see also [4, 9, 10] for a commented, short description). Important criteria in this concept are JIT (Just-in-time) production, zero holdup, inherent safety, modularity and the KISS (keep it simple, stupid) principle. Based on this conceptual definition, Rinard describes different phases in plant development. Essential for his entire work is the pragmatic way of finding process solutions, truly of hybrid character ]149] (miniaturization only where really needed). Recent investigations are concerned with the scalability of hybrid micro-reactor plants and the limits thereof ]149], Expliddy he recommends jointly using micro- and meso-scale components. 

Fantozzi et al. [73] presents the study of the carbon footprint of a typical food product in Central Italy truffle sauce. This is a mixture of vegetable oil and truffle in proportions of 33% and 67% respectively and minor components and spices (garlic, salt, pepper, etc.). Both truffles and olives are cultivated and harvested in a farm in Umbria (Italy). Olives are crushed in a mill that is situated few kilometers from the farm. Once it has been produced, the extra virgin oil, together with the truffle, is transported to another facility to produce bottled truffle sauce. The carbon footprint calculation is based on ISO 14076 technical standard. Product Category Rules (PCR) have been developed (see Table 7). 

MERICAT A process for removing mercaptans from petroleum fractions by a combination of catalytic oxidation and extraction with aqueous sodium hydroxide, using a proprietary contactor based on a bundle of hollow fibers. The sulfur products are disulfides, which remain in the hydrocarbon product. Developed by the Merichem Company, Houston, TX, and used in 61 plants as of 1991. Mericat II is a variation which includes a carbon bed too there were four installations as of 1991. See also Thiolex. 

Uhde-Hibemia A process for making a mixed ammonium nitrate - ammonium sulfate fertilizer (ASN) - which is less liable to explode than ammonium nitrate. Sulfuric acid is added to aqueous ammonium nitrate and ammonia gas passed in. The double salt crystallizes out. Additives are used to improve the handling characteristics of the product. Developed by Hibernia and licensed to Friedrich Uhde. See also Victor. 

The solution developed (see Figure 5.5) considers simultaneously, and in an optimal way, the most important aspects affecting the copper production. In order to cover the process itself and the necessary information and decision flow, the solution builds on a valid and robust process model that captures the main chemical reactions and is able to link the variable material amounts with predicted processing times. The main input data comprises ...
