International production portfolio

Because of a strategic change in product portfolio initiated in 2000, Shell International Chemicals has announced its withdrawal from the engineering plastics market. 

It is evident from Figure 5.4 that although ORP is not so detailed as MRPII the key steps of the process are similar. From the business plan, a sales and operations plan which covers key products and resources needed to deliver the business plan. The monthly sales and operations planning meeting by senior managers approves the master operations plan. The operations team will review the product portfolio, supplier stams and the capacity of own resources, and ensure that purchase orders are raised to procure appropriate resources or services from suppliers. If the capacity of own resources are adequate then an internal control document for the customer order is processed. But a partnership with customers and with suppliers can and will achieve very obvious benefits to... 

Organizational factors—synergism with other products of the firm, taking advantage of internal strengths of the firm, diversify the risks of the total firm investment portfolio. 

Well before the wide use of organoselenium compounds in chemistry, it was discovered that electrophilic selenium compounds of the type RSeX add stereospecifically to alkenes.45 Since that time this reaction has been an important tool in the portfolio of organic chemists and has been used even for the construction of complex molecules. Comprehensive reviews on this chemistry have appeared46-49 and in recent times the synthesis of chiral selenium electrophiles and their application in asymmetric synthesis has emerged. As shown in Scheme 1, the addition reactions of selenium electrophiles to alkenes are stereospecific anti additions. They involve the initial formation of seleniranium ion intermediates 1 which are immediately opened in the presence of nucleophiles. External nucleophiles lead to the formation of addition products 2. The addition to unsymmetrically substituted alkenes follows the thermodynamically favored Markovnikov orientation. The seleniranium ion intermediates of alkenes with internal nucleophiles such as 3 will be attacked intramolecularly to yield cyclic products 4 and 5 via either an endo or an exo pathway. Depending on the reaction conditions, the formation of the seleniranium ions can be reversible. 

This is a series of events that occurs on a continuum, and the main characteristic is the internally generated cash flows that provide the wherewithal for R D investment to come from the portfolio of existing products. To provide the necessary cash flows, this portfolio must contain products that have a range of price-marginal manufacturing cost differentials.

Since Lonza carried out its first homogeneous asymmetric hydrogenation on a 17 ton scale in 1994, the development and application of asymmetric hydrogenations has been a major strength in Lonza s technology portfolio. The applications in Lonza have varied from internally-generated projects, for end-products marketed by Lonza, to projects in the custom-manufacturing field, in which the Lonza Exclusive Synthesis department is active. This chapter will illustrate how process de-...
