Reference numeral 21 denotes an output device for the final evaluation rank determination result.

  FIG. 2 is a flowchart of a safety climate evaluation method in a railway technical workplace showing an embodiment of the present invention.

  In the following, the safety climate evaluation method in the railway technical workplace will be described in turn.

[Preparation before scoring]
(1) First, the collected data is inspected (step S1).

  The collection data obtained at the target workplace is input by the input device 2. At this time, if no answer (missing value) occupies 1/3 to 1/2 in the survey form of the respondent, all the data of the respondent is deleted. In addition, the calculation is stopped when the data collected at the evaluation target workplace is 20 or less.

  In this system, a new evaluation item can be added to an already set evaluation item. That is, an evaluation item to be newly added is input. Then, the content importance evaluation system is activated.

In this content importance evaluation system, first, it is evaluated whether the content of the new evaluation item is related to safety or not at all. (0,1)
If the content of the evaluation item is evaluated to be related to safety to some extent, how important is it (in terms of positive and negative impacts)? Is evaluated on a 7-point scale.

For example,
If the evaluation item to be newly added is “A task that allows you to know the quality of work (good or bad) immediately”, as shown in FIG. 3, “Not related”, “Effects on the negative side”, “Plus” “Effect on the surface” and “Neither” are evaluated, and an evaluation value is set for each.

  It is determined whether or not the above evaluation meets the following criteria, and it is determined whether or not a new evaluation item is added.

Criteria (a): More than 10% of researcher DBs (databases) answered “items that have nothing to do with safety” or more than 20% of those in charge and new DBs have “no relationship with safety” Criteria (b): More than 10% of all DBs are items whose responses on the impact of importance (plus and minus) are reversed. Judgment is made by adding a new DB to the answer of DB + person in charge DB.

  If any of the criteria (a) and (b) is met, the hold is determined (restored in the hold DB).

  On the other hand, if the criteria (a) and (b) are not met, the average value of the values evaluated in seven stages in the above evaluation is calculated as a new evaluation item, and the weight value is calculated according to the rank shown in FIG. Set.

[Scoring for each evaluation item]
(2) Next, the raw point conversion unit 5 performs raw point conversion of each evaluation item. At this time, the process for the reverse item is also performed (step S2).

  For example, the evaluation item “Accident prevention is more important than anything in the workplace” is converted into a raw point as follows (see FIG. 4).

Not applicable at all -3
-2 not so much
If anything, it does not apply -1
Neither 0
If anything, it applies 1
Applicable to some extent 2
Very applicable 3
On the other hand, for the reversal item that “the way of work is too complicated”, a raw point that is reversed from normal to positive is assigned as follows.

Not applicable at all 3
Not very applicable 2
If anything, it does not apply 1
Neither 0
Somewhat true -1
Applicable to some extent -2
Very applicable -3
Thus, the raw point conversion of the evaluation items is performed for each item.

  (3) The representative value of the workplace is calculated and stored in the storage unit 6 (step S3).

  The average value of the raw score for each evaluation item for each target workplace is calculated.

Where n is the number of valid respondents in the workplace
a: Some evaluation factor
m _a1 : average value for the first item of evaluation factor a
SD _a1 : Standard deviation for the first item of evaluation factor a,
X _a1 : As the raw point conversion value of the first item of evaluation factor a,
m _a1 = (X _a1-1 + X _a1-2 +... + X _a1-n ) / n (1)
SD _a1 = √ {[(X _a1-1 −m _a1 ) + (X _a1-2 −m _a1 ) +... + (X _a1−n −m _a1 )] / n} (2)
It is.

  (4) The “content importance” rank of each item is weighted, and the calculated value is stored in the storage unit 7 (step S4).

The weight of the content item importance rank of the evaluation item is added to the above average value m _a1 of the workplace (see FIG. 5, FIG. 6, Table 1 and Table 2). The content importance rank and the weight value are shown in Table 1.

内容重要度ランクはＡ〜Ｅの５段階であり、ランクＡは重み付け値「３．０」，ランクＢは重み付け値「２．５」，ランクＣは重み付け値「２．０」，ランクＤは重み付け値「１．５」，ランクＥは重み付け値「１．０」であり、これらを職場の平均値に積算する。より具体的な評価項目と内容重要度ランクの例を表２に示す。

The content importance ranks are in five stages of A to E, rank A is weighted value “3.0”, rank B is weighted value “2.5”, rank C is weighted value “2.0”, rank D is The weighting value “1.5” and the rank E are weighting values “1.0”, and these are added to the average value in the workplace. Table 2 shows examples of more specific evaluation items and content importance ranks.

各評価項目の内容重要度ランクは、運転系統用〔輸送指令、駅（安全）、乗務員〕と保守系統用用（車両、施設、電気）の二通りに分けてＡ〜Ｅの５段階に分類される。素点変換された値が−３〜３の値であるため、積算後の得点は、「−９」〜「９」の間になる。

The content importance rank of each evaluation item is classified into five levels, A to E, for operation system (transportation order, station (safety), crew) and maintenance system (vehicle, facility, electricity). Is done. Since the value subjected to the raw point conversion is a value of −3 to 3, the score after the integration is between “−9” to “9”.

  Table 3 shows the number of evaluation items for each evaluation factor and content importance rank.

〔各評価要因に対する採点〕
（５）評価要因の得点を算出し、記憶部８で記憶する（ステップＳ５）。

[Scoring for each evaluation factor]
(5) The score of the evaluation factor is calculated and stored in the storage unit 8 (step S5).

Scoring the weighted contents importance rank as described above, calculates the average value for each evaluation factor, the workplace score F _a for the evaluation factors this.

Where a: some evaluation factor
k: Number of evaluation items used in the survey for a certain evaluation factor
Y _a1 : Value after weighting for the first item of evaluation factor a
F _a : If the score of evaluation factor a is
F _a = (Y _a1 + Y _a2 +... + Y _ak ) / k (3)
It can be expressed as.

  (6) Reflecting the distribution status “approach level” of the same region or occupation system, the value is stored in the storage unit 9 (step S6).

Regarding the score F _a of the workplace for each evaluation factor described above, the relative position of the score of the target workplace is evaluated as the degree of effort in the score distribution of the same conditions such as the same region and the same job category. Here, the average value and standard deviation of the score distribution under the same conditions are calculated, and the standard score based on the average value is calculated.

Where: a: some evaluation factor
F _a : Score of evaluation factor a in _a certain workplace (score before reflecting “Effort level”)
FM _a : Average value of score of evaluation factor a in workplace group of the same condition Fσ _a : Standard deviation of score of evaluation factor a in workplace group of the same condition FF _a : Compared with workplace group of the same condition, Standard score of evaluation factor a after reflecting “Effort”. However, when FF _a <20, all F F _a = 20, and when FF _a > 80, all FF _a = 80
Then,
FF _a = [(F _a −FM _a ) / Fσ _a ] × 10 + 50 (4)
It becomes.

An example of calculation of the standard score FF _{a for} the evaluation factor in FIG. 7 is shown.

  (7) A final evaluation rank is determined (step S7).

Against workplace standard scoring FF _a for each evaluation factors described above, the light of the final evaluation rank of 5 steps as shown in FIG. 8, to obtain the final evaluation results.

  The final evaluation rank is as shown in Table 4.
