Application of AHP to Vessel Operations

Describe system - The system or operation under consideration is described in detail, highlighting all the equipment within the system that will be operated to achieve the desired objective of the defined operation. 

Identify tasks to be carried out - Identify all tasks that are to be carried out to achieve the objective of the operation and present these tasks in the order that they should be carried out. This information can be represented by means of a flowchart. The order by which the tasks are carried out should reflect the normal safe working procedure of the system. To 

Determine operator behaviour - For each of the tasks identified in Step 2, determine the required operator s behaviours. Three types of behaviours are considered namely, skill-based, rule-based or knowledge-based behaviour. These behaviours are discussed in Sections 9.3. 

Determine the probability of occurrence - Using a generic database, determine the probability that a human error might occur while carrying out the task specified in Step 2. Use the information developed in Step 3 to assign the probability of occurrence of the human error. 

Determine the severity of occurrence - The severity of a human error should take into account the consequences of the error on the system, operation, environment and operator. This can be quantified in monetary terms or downtime.

The flowchart in Figure 9.1 illustrates the steps involved in carrying out the application of AHP to vessel operations (Pillay (2001), Pillay and Wang (2001)). This approach can be executed in the following seven distinct steps ...
