Operating Ratios

As shown by the curve the transformation yield is almost maximum for a molar ratio of 40 % in cuprous oxide and does not increase significantly for higher quantities of the catalyst. The best operating ratio seems to be between 5 and 10 % moles of cuprous oxide in regard to the chlorobenzene. 

From the results of the more extensive experiments using a range of organic solvents, typical values of operating ratios required to reduce an organic lead level of 10 ppm to less than 1 ppm are 10 < Vaq/Vorg < 20, 2 < Cr/Cl < 3. 

Rupture tolerance is the range on either side of the marked or rated burst pressure. Operating ratio is the ratio of the maximum operating pressure to...

Co. Ltd (SPR) was founded to recycle the waste plastics collected in Sapporo city, where 13 500 t has been baled every year. This system has received excellent support by Sapporo city. However, only half of the baled plastics is used in the SPR liquefaction plant located just next to the baling plant due to the tender system controlled by JCPRA. Thus, the operating ratio of the SPR plant is not so high, and this also raises the treatment cost of waste plastics, as does the small scale. The remaining half is used for the iron and steel industry, far from Sapporo. The third liquefaction plant constructed at Mikasa city, Hokkaido stopped this March, since sufficient raw plastic waste could not be obtained. 

Dividing the electricity load of the timber factory that can be substituted into three parts, the capacity of each part is 500-600 kW, so the biomass power plant can keep higher operation ratio. 

Operating Problems. During the startups of the first two plants there was some difficulty, with solution overloading, mainly because of upsets in the Claus units and in spite of the fact that these plants are designed with generous over-capacity. The frequency of these upsets quickly decreased as personnel learned to maintain proper operating ratios in the Claus units. For example, a 5% deficiency in the amount of air in the Claus unit can double the load on the Beavon plant. 

Note Lost opportunity is defined as the weekly average revenue per power unit (truck) multiplied by the number of weeks the unit sat idle, multiplied by an operating ratio of 95%. 

Space utilization It is about how efficient the resource (space of the warehouse) is utilized. Good space utilization promotes productivity, operating ratio of... 

The operating ratios are in the domain of Management Accounting for tactical managanent and these ratios can be classed as follows. 

Understanding ratio analysis is foundational to making sense of financial and operations ratios. An organization s successes and areas in need of attention from management are highlighted by performance ratio analysis. Ratios are used to evaluate the performance of an organization, an industry, and management personnel. 

Financial statements were explained in detail in Chapter 3, providing a foundation to understand ratio analysis. This chapter will introduce many of the common financial performance ratios that executives and analysts use. In addition, the chapter will explain how to compute ratios, what information the ratios offer for decision making, and how to consider multiple factors that are critical to fully understanding the ratios. In subsequent chapters, how operations and supply chain ratios affect and influence financial ratios will be examined. Operations ratios, after all, are used to ensure that financial performance meets the e q)ectations of creditors, investors, and executives. Ultimately, these ratios provide information about an organization s financial health and ability to continue operations. 

The DuPont model (Figure 6.1) when created in a spreadsheet shows instantly how a change in any value affects ROA and ROE, among other financial and operational ratios. Inserting new values into the model provides immediate feedback about a company s operations, supply chain decisions, and policies. 

For equipment protected by rupture disk, the maximum operating pressure equals to the minimum burst pressure times the operating ratio of the rupture disk. The minimum bust pressure is calculated by following rule For marked bust pressure above 40 psig, it equals to the minimum marked burst pressure minus 5% tolerance. For marked bust pressure less than or equal to 40 psig, it equals to the minimum marked burst pressure minus 2 psi tolexance. 

Depending on the type of rupture disk, its operating ratio Is different For example, reverse-acting rupture disk has the highest operating ratio 90-95%, and forward-acting solid metal rupture disk has the lowest operadng... 

The value of the concession is calculated on the basis of the expected profit stream (total revenue minus operating costs) and the operating ratio (total revenue/operating cost). The value of other potential contributions from developers/land owners in the form of cash payments could also be included here.
