Multi-objective optimization (MO) plays an important role in engineering design, management, and decision-making in general. Usually, a decision maker needs to make tradeoffs between disparate and conflicting objectives. The field of multiobjective optimization defines the art and science of making such decisions. 

If the product is an engineering service, then the price is determined by the availabiHty, reputation, and price of competitive providers, as well as the uniqueness and scope of the service. Examples iaclude engineering design, technical laboratory services, project management, and constmction. 

Because many of the techniques, especially those associated with the recovery of materials and energy and the processing of solid hazardous wastes, are in a state of flux with respect to application and design criteria, the objective here is only to introduce them to the reader. If these techniques are to be considered in the development of waste-management systems, current engineering design and performance data must be obtained from consultants, operating records, field tests, equipment manufacturers, and available literature.

As w as mentioned earlier, extra rows are provided as can be seen in Figure 1. This gives extra flexibility needed for process design case studies. Often, the set of case studies initially envisioned by the engineer or manager are not sufficient to answer all questions. The extra rows allow intermediate recycles or intermediate flows from or additions to the plant that might not have been envisioned initially. Another value of the intermediate rows is to provide component values at intermediate points in the process. The breakeven value of a proposed purchase stream from another plant would be one use of intermediate component values. 

The engineer s motto to life is Life is a tradeoff and it eomes into play here. It is impossible to design a power supply system that meets all the requirements that are initially set out by the other engineers and management and keep it within eost, spaee, and weight limits. The typieal initial requirement of a power supply is to provide infinitely adaptable funetions, deliver kilowatts within zero spaee, and eost no money. Obviously, some eompromise is in order. 

The key components in the fuel vapor control system include the fuel tank, vapor vent valves, vapor control valve, vapor tubing, the activated carbon canister, and the engine vapor management valve (VMV) [25,26], During normal vehicle operation, fuel tank vapor pressure is relieved through the use of vapor vent valves installed in the vapor dome of the fuel tank. The vent valves are designed to allow for the flow of fuel vapor from the tank, and to assure that liquid fuel does not pass through the valve. 

The other category of latent failures can occur at the level of engineering design or management policy. For example, the design of a scrubbing system... 

An overall economic evaluation must be made to ensure that the contemplated project for petroleum development will recover sufficient capital to pay for the total cost of development, installation and assembly effort of the company. Further, the capital return must yield a financial return consistent with the overall company risk involved. Thus, it is very important that the petroleum engineer designing a recovery system understand the company s evaluation criteria that will be used by management in judging whether a new project is to go forward. Chapter 7 (Petroleum Economics) has detailed discussions of general engineering economics and product (or project) evaluation criteria. 

Performing a checklist analysis requires access to engineering design procedures and operating practices manuals and must be performed by a team with appropriate expertise. An experienced manager or staff engineer should review the results and direct follow-up actions.
