An Example Algorithm

The basic algorithm steps below describe performing a risk-based PSSR. They will be expanded upon in Chapter 5 - The Pre-startup Safety Review Work Flow Process. 

Become aware of a triggering event (a change in regard to process safety or other organizationally defined standard). 

Assess the event s need for management of change and pre-startup safety review. 

GUIDELINES FOR PERFORMING EFFECTIVE PRE-STARTUP SAFETY REVIEWS 

Apply a qualitative risk-based analysis to the event to determine the event potential severity and likelihood, o A risk matrix o A risk questionnaire o Another method of assessing risk Assess the PSSR event in regard to its complexity using the risk-based analysis results.

An example algorithm [19] for performing a Metropohs Monte Carlo simulation is as follows ... 

An example algorithm is the one-bit full adder which is shown in Table 9.2 for the classical and quantum forms of the algorithm [21]. The one-bit adder adds three one-bit numbers (A, B and Qn) to produce output bits (S = A + B - -Cin and Cout)- The carry (Qn and Cout) are bits from previous or future additions, respectively, as would occur if the sum of the numbers, S, is greater than or equal to two. This is analogous to addition in the decimal system, as when the number is greater than or equal to 10 then we carry a 1 to the next place value. The quantum form of the one-bit adder must include one additional input (D) and two extra...
