The operations group will develop general operating and maintenance objectives for the facilities which will address product quality, costs, safety and environmental issues. At a more detailed level, the mode of operations and maintenance tor a particular project will be specified in the field development plan. Both specifications will be discussed in this section, which will focus on the input of the production operations and maintenance departments to a field development plan. The management of the field during the producing period is discussed in Section 14.0. 

GAMESS is designed to have robust algorithms and give the user a fairly detailed level of control over those routines. This makes it better than many other codes at modeling technically difficult systems, such as transition metals and electronic excited states. 

The detail plan for each audit may include dates if it is to cover several days but the main substance of the plan will be what is to be audited, against what requirements, and by whom. At the detail level, the specific requirements to be checked should be identified based upon risks, past performance, and when it was last checked. Overall plans are best presented as program charts and detail plans as checklists. Audit planning should not be taken lightly. Audits require effort from auditees as well as the auditor so a well-planned audit designed to discover pertinent facts quickly is far better than a rambling audit which jumps from area to area looking at this or that without any obvious direction. 

Eq. (1) would correspond to a constant energy, constant volume, or micro-canonical simulation scheme. There are various approaches to extend this to a canonical (constant temperature), or other thermodynamic ensembles. (A discussion of these approaches is beyond the scope of the present review.) However, in order to perform such a simulation there are several difficulties to overcome. First, the interactions have to be determined properly, which means that one needs a potential function which describes the system correctly. Second, one needs good initial conditions for the velocities and the positions of the individual particles since, as shown in Sec. II, simulations on this detailed level can only cover a fairly short period of time. Moreover, the overall conformation of the system should be in equilibrium.

Once the worker has a display which enables the whole furnace unit to be monitored at a glance, it is then necessary to supply more detailed information on each individual furnace. This display should represent the process in a way which facilitates comprehension of the heat transfer stages and provides all relevant information required to fulfill the objecHves of safe and efficient firing. Figure 7.17 presents a recommended graphic display at a more detailed level of system description.

The identified enzymes need to be characterized on a more detailed level before application in biotechnological processes. 

The reaction network for 5,6-benzoquinoline [101] has been proposed in a more detailed level than that of acridine. In this network, conversely to acridine network, only one primary hydrogenation product, l,2,3,4-tetrahydro-5,6-benzoquinoline, was identified, and in contrast to the quinoline case however, no aniline derivatives were detected.

The CFD models considered up to this point are, as far as the momentum equation is concerned, designed for single-phase flows. In practice, many of the chemical reactors used in industry are truly multiphase, and must be described in the context of CFD by multiple momentum equations. There are, in fact, several levels of description that might be attempted. At the most detailed level, direct numerical simulation of the transport equations for all phases with fully resolved interfaces between phases is possible for only the simplest systems. For... 

Production planning has to determine on the detailed level which production step (operation) has to be carried out at which time and on which resource. For this purpose a resource allocation problem has to be solved (this is denoted as a scheduling problem in mathematical theory). It is natural to desire this allocation to be optimal in a certain sense (minimal number of setups and/or violations of requirements dates, etc.). 

The retrieval of cases can be done in several steps. The first step is the evaluation of the process with the stored cases. This way can be seen, if the process is safer or unsafer than the alternative processes. The second step is the safety evaluation of specific process systems, subsystems or pieces of equipment. The database contains improvement recommendations to avoid the same accidents happening again. The evaluation of processes can be extended to detailed level. Also the equipment details or safety valves etc. can be checked on this level.

Figure 18 shows a list of three deviations, at different aggregation levels. At the highest aggregation level (lowest detail), all deviations are equal, on the lowest aggregation level (most detailed level), all three deviations differ. Thus a re-occurring deviation is identified on the lowest aggregation level as present and where all three deviations are superficially equal. 

Some tools and authors use the term class diagram. We reserve class for the most detailed level of design, representing what s actually in the code. A class box (marked class ) shows all the directly stored attributes and links of its instances. A type is more general Its attributes and associations represent information that can be known about any of its members, without stating how. We use types much more than classes in analysis, and both during design. 

The refinement relation between the two levels of description documents this mapping. The state chart shows how the parameters and state changes in the detailed action sequence translate to the abstract action and its parameters. In this example we use a counter attribute to define this mapping it is an attribute of a specification type representing a restocking in progress at the more detailed level (Pattern 14.13, Action Reification). 

In action abstraction, no invoker need be identified Any participant can initiate it. The exact sequence is determined by the designs of all participants (some of whom could be human) we can say only what the smaller actions are and the constraints on how they might be combined. Also, the abstract action may never be directly invoked at the detailed level. 

In the second case, the imported model contains partial definitions the extenders add the missing pieces in different ways. For example, you might have two slightly different networking requirements one for small offices and a second one for large offices. They could perhaps contain different collaboration or type definitions at a detailed level but be based on a common underlying abstract model. 

All these packages are concerned with modeling business activities. Some of the actions at the detailed levels may be supported by a software application. 

At a higher level, it is useful to document the dialog flow of the UI, shown as a state transition diagram, where each state corresponds to a particular window that is active at that point in the interaction. At a more detailed level, we need uniform mechanisms to assemble the user interfaces and respond to their events. 

Pattern 14.13, Action Reification, introduces a common modeling pattern. When a use case is refined into a sequence of finer-grained actions, it is useful to model the abstract use case in progress as a model type in the detailed level, going through a life cycle as the detailed actions take place. 

Operations processes are on the operative level focusing on order scheduling for a specific day or point in time. The schedules have a shorter horizon than the planning processes focusing on days. The schedule is monitored and updated continuously - daily to weekly. Orders are managed on the most detailed level for single customer respectively suppliers and articles. 

At the heart of the model are the heat and mass balance equations governing the chlorine gas, brine and amalgam layers within the cell as illustrated by Fig. 20.3. At a more detailed level each cell is divided into eight zones. Conditions within each zone are assumed to be constant and there is a trade-off between model accuracy and execution time associated with the number of zones. Typically eight zones have been found to be a good compromise.
