Emergency Stop Push Button Switch 6. Signal Lamp Turn gear engaged 7. Solely an emergency stop is possible from other operating stands, too. In position Remote Control, the engine can be started from the SaCoS operating panel or, optionally, from external systems. In this mode of operation, the speed set point adjustment is carried out from SaCoS or the external system, which is normally the power plant control system. By using engine speed setting switch in position "Lower", engine speed setting is count down step by step as long as switch is hold in position.
By using engine speed setting switch in position "Raise", engine speed setting is count up step by step as long as switch is hold in position.
Momentary Contact Push Button Start At local operation the momentary contact push button Start permits the operator to start the engine, if there is no start blocking active via SaCoS.
Momentary Contact Push Button Acknowledge Engine is turned After turning the engine by the operator, this has to be acknowledged by pressing this push button. This function is an option 5.
Before another engine start is possible, the emergency stop switch must be released by pressing again. As long as the red lamp of the switch is illuminated, an emergency stop is active and an engine start is not possible.

This lamp is also illuminated in case the emergency stop was, for instance, triggered in the engine control room or another place. The Reset then is to be carried out from there.
Signal Lamp Turning Gear Engaged The signal lamp indicates that the turning gear is engaged and that an engine start is not possible. SaCoS will not permit a regular engine start.
Emergency Stop Push Button 9. Emergency Start Push Button 8. Emergency Stop Push Button Mechanical The emergency stop valve is provided with a mechanical emergency stop push button, which directly acts on the emergency stop valve. Thus, an engine emergency stop is possible even in case of a safety system breakdown. Emergency Start Push Button Mechanical At the emergency start valve, another push button is installed for mechanical actuating of the start valve. It works independently of the SaCoS system and can be used to start the engine in case of an engine control breakdown Emergency Start.
For this start function, no start blockings of the operating and control system are active. The operator is fully responsible for the engine lubrication and cooling, as well as for the condition of the driven system!
Table 1: Hierarchy Structure This structure is different from the traditional AHP, as in the last level there are not alternatives. The evaluation is performed from the intensity levels assigned to each sub- criteria related to each alternative, instead of evaluating the pair-wise comparisons of alternatives.
All the sub-criteria are represented with the same evaluation categories: Excellent, Middle and Lower. The Tables 2, 3 and 4 reflects the obtained data of this initial study. This set of criteria and sub-criteria are meeting the conditions defined by axioms of ROY and BOYSSOU : a Exhaustiveness: all relevant aspects to characterize the problem and the most appropriate alternative were considered.
All criteria and sub-criteria were taken from his work, which was based on interviews with players working with projects in this area. Despite the fact that we have twelve criteria considered and, sometimes, up to twelve sub-criteria in the same criterion, they are necessary and complementary as shown by BARATEIRO The analysis concluded that this aspect is necessary to maximize the investments in a petrochemical plant.
In this approach the decision-makers' judgments are aggregated into a single decision matrix by calculating the geometric average of the trials.
The decision matrix of the group is shown in the Table 5. Table 5: Evaluation Matrix for Main Objectives For the matrix defined in Table 5 the inconsistency degree was calculated at 8. The values of the auto-vector correspond to the importance degree weights that must be used in the application of criteria C1 to C From Table 6 to 17 we have the group decision matrix for the sub-criteria of each criterion C1 to C Table 7: Evaluation Matrix for Experience and References For the matrix defined in Table 7 the inconsistency degree was calculated at 5.
The values of the auto-vector correspond to the importance degree weights that must be used in the application of sub-criteria C to C Table 9: Evaluation Matrix for Local Support For the matrix defined in Table 9 the inconsistency degree was calculated at 5.
Table Evaluation Matrix for Portfolio of Field Instruments For the matrix defined in Table 11 the inconsistency degree was calculated at 3. Table Evaluation Matrix for Portfolio of Flow Meters For the matrix defined in Table 12 the inconsistency degree was calculated at 3. Table Evaluation Matrix for Portfolio of Analyzers For the matrix defined in Table 13 the inconsistency degree was calculated at 5.
Table Evaluation Matrix for Portfolio of Predictive Maintenance For the matrix defined in the Table 15 the inconsistency degree was calculated at 9.
Table Evaluation Matrix for Custody Transfer Portfolio For the matrix defined in Table 17 the inconsistency degree was calculated at 6.
Finally we have the group decision matrix regarding the intensity levels.

When working with ratings, SAATY advises that the priority vectors be idealized, that is, the best category is assigned with the value 1.
Table 18 reflects the results for the intensity levels.
The idealized values will correspond to the score obtained by the supplier in accordance with each sub-criteria evaluation. Figure 5: Weights for Main Criteria b Weights for each sub criterion: values obtained from the auto-vector of Table 6 to Table 21 shows an example of an evaluation performed for a supplier.
Conclusion Globalization and competition are demanding an increasing efficiency for the supply chain. Automation is an important item in terms of impacts on the CAPEX and OPEX and the supplier proper choice of this item is very relevant to the implementation of a large petrochemical project.
In this type of project, only the MAC may represent a download order around of USD M and this fact alone justifies a technical evaluation of suppliers based on a methodology of proven success.
The use of this methodology can reduce the number of trials required from the decision maker when the alternatives are numerous. Most of the results obtained in this article are aligned with the initial work produced by BARATEIRO : the supplier's capability, experience and references, the project execution plan, the technology and the portfolio of asset management were the most important items in both studies.
We understand that the model proposed in this paper, for technical analysis of the MAC suppliers, can contribute for the choice of the best alternative that meets the technical requirements for such large petrochemical projects, reducing impartial judgments that may occur when an appropriate methodology is not used. Ho, W. European Journal of Operational Research, , Rio de Janeiro, SAEN, R. McGraw-Hill, New York, International Journal of Services Sciences, 1 1 , Table Evaluation Matrix for Portfolio of Flow Meters For the matrix defined in Table 12 the inconsistency degree was calculated at 3.
The Reset then is to be carried out from there. At the first moment of the crisis all segments were affected, however, the Brazilian oil and gas market remained the majority of its investments based on Petrobras plans, the oil state company, to be one of the five largest integrated energy companies in the world by Journal of Mathematical Physics, 54 It is usually attributed to Ferdinand de Saussure the invention of the theory of the linguistic sign.
The Multiple Criteria Aspects For the purposes of this paper we considered the use of multi-criteria techniques to solve the supplier selection problem SSP.
It works independently of the SaCoS system and can be used to start the engine in case of an engine control breakdown Emergency Start. McGraw-Hill, New York,
