SPECIFIC PROBLEMS

The main specific supply chain management problems are  

Demand planning and forecasting. Demand data are required for other supply chain management activities. Demand planning attempts to influence demand to make supply chain operations more efficient. 

Finance. In the supply chain management framework, this concerns planning of supply chain costs and controlling supply chain performance. 

Production planning and manufacturing. These problems address creation of products and services in response to customer demand. It includes such supply chain management concerns as master production planning, capacity allocation, scheduling, maintenance of manufacturing facilities, and manufacturing quality. 

Marketing and sales. The primary concerns of these managerial problems are attracting customers and processing their orders.

There are no classification requirements for routine NDE beyond thickness testing and visual inspection except for repairs, modifications or where service history has identified a specific problem in which case the Surveyors will request NDE at the same locations in similar ships. Under circumstances where visual inspection has found evidence of fatigue cracking the Surveyor can also call for NDE to assess the full extent... 

Clearly, no pronounced clustering of the compounds according to MOA can be discerned. What is the problem. Is the chosen structure representation not appropriate for this specific problem ... 

The method is incorporated into the CORA (Classification of Organic Reactions for Analysis) system [Sf Here, wc want to illustrate the merits of this approach by an example of its application to a specific problem, the prediction of the regioselec-tivity of a ring closure reaction. This is detailed in the following tutorial. 

IlyperChem has a set of optimi/.ers available to es.plore potential surfaces. These differ in their generality, convergence properties and conipntaiioiial requirements. One must be somewhat pragmatic about optirn i/ation andswitch optirn izers or restart an optimizer when It encounters specific problems. 

At the top of File Segment 5-1 is a heat of fomiation information block. Two sums are listed One is a sum of nomial bond enthalpies for ethylene, and the other is a sum selected from a parameter set of stiainless bonds. Both sets of bond enthalpies have been empirically chosen. A group of molecules selected as nomial generates one parameter set, and a group supposed to be strainless is selected to generate a second set of str ainless bond enthalpies designated SBE in Eile Segment 5-1. The subject of parameterization has been treated in detail in Chapter 4. See Computer Projects 3-6 and 3-7 for the specific problem of bond enthalpies. 

The range of integration and the meaning of the variables x will be defined by the specific problem of interest for example, in polar coordinates for one particle, x r,0,( ), and for N... 

We now turn from the general problems of peptide synthesis to specific problems connected with three currently important procedures, namely ... 

We defined the equation of motion as a general expression of Newton s second law applied to a volume element of fluid subject to forces arising from pressure, viscosity, and external mechanical sources. Although we shall not attempt to use this result in its most general sense, it is informative to consider the equation of motion as it applies to a specific problem the flow of liquid through a capillary. This consideration provides not only a better appreciation of the equation of... 

So far, so good. The situation is really no different, say, than the ideal gas law, in which the gas constant is numerically different and has different units depending on the units chosen for p and V, The unit change in Example 10.1 is analogous to changing the gas constant from liter-atmospheres to calories it is apparent that one system is physically more meaningful than another in specific problems. Several considerations interfere with this straightforward parallel, however, and cause confusion ... 

Acetic acid is also transported ia barges, sometimes ia amounts of 1500 to 1750 tons. Acetic acid is not as hygroscopic as some other anhydrous organic substances, but barge shipments occasionahy have specification problems because of wave splashing iato the tanks or other careless handling. 

Has explanation in detail of how the prior patents and Hterature have been improved and what specific problems were solved been provided ... 

Coordinate Systems The commonly used coordinate systems are three in number. Others may be used in specific problems (see Ref. 212). The rectangular (cartesian) system (Fig. 3-25) consists of mutually orthogonal axes x, y, z. A triple of numbers x, y, z) is used to represent each point. The cylindricm coordinate system (/ 0, z Fig. 3-26) is frequently used to locate a point in space. These are essentially the polar coordinates (/ 0) coupled with the z coordinate. As... 

Problem Definition InteUigent selection of a separator requires a careful and complete statement of the nature of the separation problem. Focusing narrowly on the specific problem, however, is not sufficient, especi ly if the separation is to be one of the steps in a new process. Instead, the problem must be defined as broadly as possible, beginning with the chemical reactor or other source of material to be separated and ending with the separated materials in their desired final form. In this way the influence of preceding and subsequent process steps on the separation step will be iUuminated. Sometimes, of course, the new separator is proposed to replace an existing unit the new separator must then fit into the current process and accept feed materials of more or less fixed characteristics. At other times the separator is only one item in a train of new equipment, all parts of which must work in harmony if the separator is to be effective. 

There are numerous machines and machine types to obtain a number of different particle-size classes from sohds having a full range of sizes, and there is much overlapping in the possibihties. Usually, one type will provide optimum economy for the specific problem involved. 

Comparative costs for conveyor systems can be based only on studies of specific problems. For example, belt-conveyor idlers are available in a range of quahties that may make the best unit cost three times as much as the cheapest. Bearing quahty, steel thickness, and diameter of rolls all affect cost, as does design for easy maintenance and repair. Therefore, it is necessary to make cost comparisons on the basis of a specific study for each conveyor application. 

Many sources contain scattered information concerning cooling water system corrosion and defects, and many literature studies describe corrosion processes and mechanisms from a predominantly theoretical viewpoint. Until now, however, no source discusses cooling water system corrosion with emphasis on identification and elimination of specific problems. Much of the information in this book is unique every significant form of attack is thoroughly detailed. Color photos illustrate each failure mechanism, and case histories further describe industrial problems. 

A chart for vibration diagnosis is presented in Table 19-9. While this is a general criterion or rough guideline for diagnosis of mechanical problems, it can be developed into a very powerful diagnostic system when specific problems and their associated frequency domain vibration spectra are... 

In this book, I have tried to assimilate the subject matter of various papers (and sometimes diverse views) into a comprehensive, unified treatment of gas turbines. Many illustrations, curves, and tables are employed to broaden the understanding of the descriptive text. Mathematical treatments are deliberately held to a minimum so that the reader can identify and resolve any problems before he is ready to execute a specific design. In addition, the references direct the reader to sources of information that will help him to investigate and solve his specific problems. It is hoped that this book will... 

Table 1 should be regarded only as a general guide. Its conciseness does not permit either absolute completeness or detailed consideration of specific problems some of these problems are being discussed in more detail in the other articles. However, the table does outline ... 

The specific problems for BEOs are mostly related to the specific processes at which they are used. One problem that does not, directly, depend on the process is the use of the exhaust system. If an exhaust is not used, naturally it cannot remove contaminants. Although BEOs are less efficient than total or partial booths, their use is still justified. When the location of the BEO is not perfect, higher flow rates are usually required for contaminant control. However, it is better to use this type of hood than to have no local exhaust. 

The steps you need to take to detect specific problems will vary depending on the nature of the problem. The part that can be proceduralized is the discovery process for detecting problems and isolating their cause. A typical process may be as follows ...
