Learning costs

Learning costs and risk bearing by the federal government As mentioned above, US federal support includes a production tax credit (PTC) of... 

Reallocation of construction and performance risks to the vendor a turnkey contract The turnkey contract with AREVA allocates the construction risk to the reactor vendor above a cost level which includes unforeseen learning costs ( 3.2 billion, that is, 2,000/kW). As a consequence of the ongoing... 

Preliminary economic assessments indicate the projected levelized busbar generation cost for the four module "equilibrium" GT-MHR plant at 600 MW(t) per module is about 35 mills/kWh (in 1994). The "equilibrium" plant reflects learning cost reductions from construction of several previous plants. This is a decrease of over 35% in busbar costs compared to the early 1980s designs of the 350 MW(t) steam... 

To make them realize the importance of the development of lateral surface, students should prepare a 3D model using card sheets. The models prepared by students not only include truncated prisms and pyramids but also the eombination of curved surfaces and flat surfaces as shown in Fig. 2. Demonstration on how to make such models was given in a class so that students learn cost-effectiveness and practical difficulties. This process is more helpful for sheet metal operations, especially for mechanical engineering sciences students. 

Overall, use of learning systems has two main advantages. First, the construction cost may be lower, certainly if the system is not construeted from scratch but uses existing software tools and components. Second, a learning system is able to adapt to changing conditions, though not always on-line. 

Conformations m which the torsion angles between adjacent bonds are other than 60° are said to have torsional strain Eclipsed bonds produce the most torsional strain staggered bonds none Because three pairs of eclipsed bonds are responsible for 12 kJ/mol (2 9 kcal/mol) of torsional strain m ethane it is reasonable to assign an energy cost of 4 kJ/mol (1 kcal/mol) to each pair In this chapter we 11 learn of additional sources of strain m molecules which together with torsional strain comprise steric strain... 

Finally, analytical methods can be compared in terms of their need for equipment, the time required to complete an analysis, and the cost per sample. Methods relying on instrumentation are equipment-intensive and may require significant operator training. For example, the graphite furnace atomic absorption spectroscopic method for determining lead levels in water requires a significant capital investment in the instrument and an experienced operator to obtain reliable results. Other methods, such as titrimetry, require only simple equipment and reagents and can be learned quickly. 

Learning Curves It is usual to learn from experience. Consequently, the time taken to produce an article, the number of spoiled batches, the cost per unit of production, etc., tend to decrease with the number of units produced. The relationships are expressed for the ideal case by... 

In general, cost data will be available for multiple units. Typically, the cost of production for 1 week or of a specific order is computed and an average cost per unit obtained. This average value Y for the batch should be plotted against the corresponding learning-cuive value X calculated oy Eq. (9-66) ... 

The cost of an initial hatch of 21 units, exchisive of special tools and setting-iip costs, averaged 120 per unit. The average cost of the next hatch of 80 units was 75.81. Let iis establish the learning curve implied hy these data and hence estimate the probable average cost of the next 50 units. We shall establish also the unit-cost curve to be used as a control during follow-iip orders. 

From Eq. (9-64) it follows that the value of the characteristic of this learning curve = 100 antilog (—0.2196 log 2) = 85.0 percent. From Eq. (9-65) the production cost of the third unit is... 

To the above costs must he added hack any unit costs omitted from those to which learning might bring improvement. These will normally include overheads and specific charges on the project such as the unit cost of special tools, jigs, etc. 

Once adopted, plans should be periodically reviewed (depending on the project) and evaluated for effectiveness and cost/benefit. If the scope of work or any worksite hazards change significantly or if lessons learned indicate a review, the plans should be revised promptly... 

Resolution Your company will have some experience of these costs for other quality programs. You should review these and if costs were excessive, try to learn from these experiences and show how they can be avoided this time. Hopefully, there will have been no excessive costs and you will be able to use the review information to defuse this concern. 

After Benefits and costs, lessons learned and changes to overall project...
