INDEX process safety elements

Like VDA 6.1, AVSQ 94 does not include the requirements of ISO 9001. In this way issues of copyright are overcome, a practice shared by VDA and EAQF but not QS-9000. However, unlike VDA 6.1, AVSQ 94 follows the 20 elements of ISO 9001 with two additional elements, covering financial considerations and product safety. Those questions that go beyond ISO 9001 are marked and as every question is numbered it simplifies the evaluation process. A scoring method is employed to classify organizations in terms of a conformity index. Each question is awarded a point (0, 2.5, 5, 7.5, or 10), where 10 points means full compliance, 7.5 points means minor inadequacies, 5 points means inadequacies in application requiring improvement, 2.5 points means serious inadequacies in application, and 0 points is used for criteria not applied. Unfortunately all questions carry the same weight as no account of the impact of omission on product quality or customer satisfaction is included. 

ABSTRACT With Analytic Hierarchy Process (AHP), this paper sorts hierarchically various index on the impact of tender invitation and evaluation for mine safety equipments and forms an orderly hierarchical structure. By means of calculation, its weight is determined. Then a objective and scientific evaluation system of bid scheme is established with the combination of quantitative evaluation and qualitative evaluation, which reduces the influence of subjective elements and reflects an open, fair and just principle of competition. 

The process of calculating the index is shown in Fig. 9.3 it is briefly commented upon below. For any concrete application, however, [9] should be consulted. Penalty factors are assigned to hazardous elements and credit factors to good safety features. 

Software System Hazard Analysis This type of analysis is conducted similar to a hardware system hazard analysis (SHA), analyzing software functional processing steps to determine whether they may have any particular hazardous effect on the system. The analysis utilizes a hazard-risk index to illustrate the severity of each potential failure. The main advantage to this method is in its ability to positively identify safety-critical hardware and software functions as well as consider the effect of the human element in system software operations. The results of the software SHA, which identifies single-point failures or errors within a system, can often be used to assist in the development of a software fault tree analysis or, to some degree, a system FMEA. However, as with the other various SWHA techniques briefly described above, this method is also time-consuming and costly to perform.
