The AHP is designed to solve complex problems involving multiple criteria. The AHP measure is a dynamic strategy created during the 1970s by mathematician Thomas l. Saaty; logical pecking order is one of multi rules dynamic technique that was initially improved. To put it clearly, it is a technique to get ratio scales from combined correlations. (AHP) is one of multi rules dynamic technique that was initially improved by prof. Thomas l. Saaty. To put it clearly, it is a technique to get ratio scales from matched examinations. Information can be obtained from genuine estimation, for example, value, weight and so forth or from abstract assessment, for example, fulfillment sentiments and inclination.
AHP permit some little irregularity in judgment since human is not generally steady.
The ratio scales are gotten from the vital Eigen vectors and the consistency file is gotten from the primary Eigen esteem. Simply need to peruse on and toward the end will comprehend. Along these lines, the guess is very acceptable. Hence, the total of Eigen vector is not one. At the point when standardized an Eigen vector, at that point get a need vector. The whole of need vector is one. AHP assists with catching both emotional and target parts of a selection. AHP fuses a valuable strategy for checking the consistency of the leader's assessments, subsequently lessening the inclination in AHP.(Saaty.2008)
3.2.1. Utilizing AHP to pick better option of transportation
The best way to select good option between multiband variable options to arrange pipelines for transportation petroleum safety by using AHP. The Analytic Hierarchy Process (AHP), introduced by Thomas Saaty (1980) is an effective tool for dealing with complex decision-making, and may aid the decision maker to set priorities and make the best decision. By reducing complex decisions to a series of pairwise comparisons, and then synthesizing the results, the AHP helps to capture both subjective and objective aspects of a decision. In addition, the AHP incorporates a useful technique for checking the consistency.
3.2.2. Checking the consistency
At the point when numerous pairwise examinations are played out, a few irregularities may regularly emerge. One model is the accompanying, accept that three rules are thought of the leader assesses that the primary model is somewhat more significant than the subsequent standard, while the subsequent measure is marginally more significant than the third basis.
Its clear irregularity emerges if the assessesment unintentionally that the third basis is similarly or more significant than the principal rule. Then again, a slight irregularity emerges if the leader assesses that the principal basis is additionally marginally more significant than the third rule.
A reliable assessment would be, for example, that the principal basis is a higher priority than the third measure.

4. YEMEN CONTEXTUAL ANALYSIS FIELDS
Even though Yemen is certainly not a significant hydrocarbon maker comparative with a few different countries in the Middle East region, the nation has adequate oil and flammable gas assets for both local interest and fares. Meanwhile, Yemen's troublesome security condition affected the production and transport of those assets.
In Oil and Gas Tasks Elective Determination utilizing AHP during the selection period of Oil and Gas extends, a few arrangements are created before Top managerial staff endorse, the top administration should be educated about the most encouraging arrangement, which could be chosen to accomplish the undertaking objectives.
Considering that not for all the arrangements the plan can be completely improved , the elective determination is regularly helped out subjective and generally emotional examination: normally the criticality positioning after assessment risk to defeat the vulnerabilities of this operation a more itemized and target approach can be utilized:
the (AHP). This paper depicts how the best option against a few seaward/inland pipeline projects has been chosen .The AHP has been applied soon after the assessment risk meeting to exploiting information related to the advantages of the plan having a place with various controls.
This procedure gives full comparison between various alternatives using numerically select the best undertaking elective from all the specialized perspectives, giving clear vision to this decision. At last, straightforward "advantages to costs ratios"
examination, likewise, the costs, intentionally put particularly for the advantages of the selections are evaluated, are remembered for the operation and the most encouraging arrangement can be distinguished.
The AHP is a standout amongst other known and generally utilized numerical dynamic process. The model utilizes human judgment to look at selection is considering changed variables, considering pairwise examination (How significant is A comparative with B?)
The AHP is an incredible and adaptable dynamic apparatus for complex, multi-rules issues. It enables leaders to pick the best other option, giving supports to their decision. The AHP introduced in this paper indicated to pipeline option determination from another seaward stage to current onshore oil terminal. To recognize different actionable sites. To study potential pipeline options from the recognized sites to the oil terminal. (Saaty,2008).
To carry out all necessary process to implement the plan, develop and lay the pipeline. To call attention to territories where more point-by-point reviews were required preceding the following plan stages.- The pipeline has been chosen having respect to the open security, the pipeline uprightness, the ecological effect, and the outcomes of break of liquid, focusing on the accompanying things. Topography and geography (seabed properties, soil properties, blocks, seismic action). Environment (earth touchy territory, region of regular protection intrigue, natural conditions).
Constructability availability, outsider necessities, restricted development period, neighbourhood imperatives. (Benuccia,2014)
