Risk factors in environment aspect
| Value | Environment | |||||
|---|---|---|---|---|---|---|
| Occurrence | Severity | Detection | Control | Information | Range | |
| 1 | It is almost impossible | No effect: the effect is unverifiable, change is not sensible | Sense perception is directly and immediately possible by anyone, at any time of the day | It does not require any regulation, spontaneously regularized | No information is required | Nobody is involved |
| 2 | Annually | Neutral: the effect is verifiable, but the caused change is not sensible | Sense perception is directly and immediately possible by anyone, but only in smooth atmospheric/optical/noise conditions (e.g. only in daytime) | Open-loop (nonfeedback) control is enough | All the information is available to know the failure modes and effects | Max. 1 person is involved in the factory, max. 1 day is the correction |
| 3 | Quarterly | Tolerable: unwanted changes can be detected, but they do not affect any essential features of the given unit | Especially difficult to detect sensory, even in daytime, under optimal conditions | Only local control, easily controllable using feedback | The failure modes and effects are known, but not all the information about effects given in advance, but can be acquired after the occurrence | 2 or 3 people are involved in the factory, or 4–5 days is the correction |
| 4 | Once a month | Acceptable as tolerated status: unwanted changes can be detected, they do affect more essential features of the given unit | Sense perception is possible only using tool (e.g. light, the use of contrast agents, the use of indicators, etc.) | requires local forecast, feed-forward control | The failure modes and effects are known, but not all the information about the effects is given in advance and also cannot be obtained after the occurrence | 4 or 5 people are involved in the company, or 4–7 days is the correction |
| 5 | Several times a month | Annoying: functions are sustainable, but conditions are deteriorating | Sense perception is not possible; however, the change is demonstrable mathematically (calculation, inventory, mass balance, etc.) | Higher-level control, easily controllable using feedback | The failure modes are known, but not all the effects, or not all information about the effects is given in advance, but can be obtained after the occurrence | Min. 6 people are involved in the company, 7-10 days is the correction |
| 6 | Once a week | Little problem: the irreversibility described above exists; however, the change is not over limit or qualification barrier, or the change is over limit, but the effect is reversible without any corrective action | Immediately can be detected by instruments in own ownership and use | Requires forecast from higher level, feed-forward control | The failure modes are known, but not all the effects, or not all information about the effects is given in advance, and can be only estimated after the occurrence | Impact on the total internal operation of the company but can be corrected internally |
| 7 | Several times a week | Problem: irreversibility exists, the change is over one limit or qualification barrier, the effect is reversible without any corrective action | Immediately can be detected by instruments from external source | Requires forecast from higher level, feed-forward control, but only partially effective | Failure modes are nor known folly and effects can be estimated only partly | Widespread involvement within the company, one business partner is involved |
| 8 | Once a day | Restrictive: the change is over each limit, regulation and so on, as a consequence the unit gets into lower quality class, but the change is reversible | Not all parameters can be detected using in-situ procedure | It requires the use of multiple control tools for multiple levels, but only partially effective | There is no information about failure modes and effects in advance, but can be obtained after occurrence | Widespread involvement within the company, more business partners are involved, environmental damage in max. 50 m radius |
| 9 | Several times a day | Harmful: the change is over each limit, regulation and so on, as a consequence the unit gets into lower quality class, the change is irreversible | Can be detected only based on sampling, in laboratory conditions | There is no influence, not controllable | There is no information about failure modes and effects in advance, and they can be obtained after occurrence only in part | Widespread involvement among the business partners, social environment and inside the company, environmental damage in 50200 m radius |
| 10 | Per shift | Terminating: the unit or the whole system ceases to exist or loses determinating features | Instrumental analytical tests cannot detect (or close to error limit), at most generation changes can be detected | There is no influence, going to unfavorable direction | There is no and cannot be obtained information about failure modes and effects | Widespread involvement among the business partners, social environment and inside the company, large publicity, environmental damage is in over 200 m radius |
