Moreover, the existing OEE loss calculation in the industry is based on the loss type summarized from the past experience to calculate and further guide the production, but has the following defects: 1. there is no clear operation guidance in the art; 2. the classification of the loss is different and is not easy to understand; 3. the loss types are not easily expanded and analyzed according to actual conditions.

Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
According to the method and the device for optimizing the performance of the production equipment based on the comprehensive efficiency of the equipment, which are provided by the embodiment of the invention, a model for acquiring the loss rate of the production equipment is constructed according to the predefined loss classification information matched with the production equipment and the equipment operation data, and the loss data related to the comprehensive efficiency of the equipment is acquired according to the model. The loss data of the comprehensive efficiency of the equipment can be accurately analyzed, and the performance of the production equipment is further optimized.
In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The method for optimizing the performance of the production equipment based on the comprehensive efficiency of the equipment, which is provided by the embodiment of the invention, is described with reference to the attached drawings.
Fig. 1 is a schematic flow chart of a method for optimizing the performance of a production facility based on the overall efficiency of the facility according to an embodiment of the present invention.
As shown in fig. 1, the method for optimizing the performance of the production equipment based on the comprehensive efficiency of the equipment comprises the following steps:
Specifically, the equipment operation data can be extracted from a database of an existing system (e.g., YMS, MES) of the enterprise.
And 102, constructing a model for acquiring the loss rate of the production equipment according to predefined loss classification information matched with the production equipment and equipment operation data.
Specifically, as an example, the predefined loss classification information includes at least: time loss rate, performance loss rate, and defective product loss rate; the device operational data includes at least: time actuation rate, performance actuation rate, and percent of pass. The model for obtaining the loss rate of the production equipment is constructed as follows:
1 is (time activation rate + time loss rate) × (performance activation rate + performance loss rate) × (yield of pass + yield of defective products).
In the actual production process, the proportion of each loss needs to be determined, and then the adjustment of the process parameters and the production plan of equipment production is guided. To improve the overall efficiency of the plant, we need to analyze and adjust the following equations: 1-the overall plant efficiency + the plant efficiency loss. The aim of the method is to improve the value of the comprehensive efficiency of the equipment and reduce the value of the efficiency loss of the equipment, and for the convenience of analysis, the method needs to specify which items are included in the efficiency loss of the equipment, so that the medicine is taken according to the symptoms and the production is optimally adjusted, so that the ideal equation is as follows: the method comprises the following steps of 1, integrating efficiency of equipment, loss of a shutdown reason 1, loss of a shutdown reason 2, loss of performance, 1+ loss of performance, 2+ loss of defective products, 1+ loss of defective products, and 2+. In order to achieve the above analysis purpose, in the model construction for obtaining the loss rate of the production equipment, the identity equation 1 is skillfully constructed (time actuation rate + time loss rate) × (performance actuation rate + performance loss rate) × (qualified product rate + defective product loss rate), so that there is a reliable theoretical basis for obtaining the loss data related to the comprehensive efficiency of the equipment.
And it can be imagined that the time loss rate, the performance loss rate and the defective product loss rate in the model can be further refined according to the business requirements, namely, the loss classification is flexibly defined or added according to the production scene, so that the loss type is easy to expand, and the problem of incomplete classification of the comprehensive efficiency loss of the equipment is solved.
In summary, the model for obtaining the loss rate of the production equipment provided by the embodiment of the invention can not only obtain the loss data associated with the comprehensive efficiency of the equipment, but also flexibly expand the loss classification, and solve the problem of incomplete classification of the comprehensive efficiency of the equipment, thereby accurately analyzing the loss data of the comprehensive efficiency of the equipment.
And 103, acquiring the comprehensive equipment efficiency of the production equipment and loss data related to the comprehensive equipment efficiency according to the model.
To facilitate the analysis, we replace the analysis terms in the model with symbols, let:
the time start rate is T, and the time loss rate is T1And there is the equation T + T1＝1；
The performance start rate is P and the performance loss rate is P1And there exists the equation P + P1＝1；
Q is the qualified product rate and Q is the defective product loss rate1And there is an equation Q + Q1＝1。
The model for obtaining the loss rate of the production equipment is constructed as follows: 1 ═ T + T1)*(P+P1)*(Q+Q1)。
Specifically, as an example, obtaining the device comprehensive efficiency of the production device and the loss data associated with the device comprehensive efficiency according to the model includes:
for 1 ═ T + T1)*(P+P1)*(Q+Q1) The decomposition is carried out, and the decomposition is carried out,
1＝(T+T1)*(P+P1)*(Q+Q1)
＝T*(P+P1)*(Q+Q1)+T1*(P+P1)*(Q+Q1)
＝T*(P+P1)*(Q+Q1)+T1
for convenience, let T be1*(P+P1)*(Q+Q1)＝T1Then, then
1＝T*(P+P1)*(Q+Q1)+①
＝T*P*(Q+Q1)+T*P1*(Q+Q1)+①
＝T*P*(Q+Q1)+T*P1+①
Let ② ═ T × P1*(Q+Q1)＝T*P1Then, then
1＝T*P*(Q+Q1)+②+①
＝T*P*Q+T*P*Q1+②+①
Let (c) T (P) Q1And since OEE is T P Q,then
1＝OEE+③+②+①
The OEE represents the comprehensive efficiency of the equipment, the time loss data related to the comprehensive efficiency of the equipment, the performance loss data related to the comprehensive efficiency of the equipment and the defective product loss data related to the comprehensive efficiency of the equipment.
And 104, optimizing the performance of the production equipment according to the comprehensive efficiency of the equipment and the loss data associated with the comprehensive efficiency of the equipment.
Specifically, as an example, optimizing the performance of the production equipment according to the comprehensive efficiency of the equipment and the loss data associated with the comprehensive efficiency of the equipment includes: and arranging all loss data in a descending order, selecting at least one loss data for analysis, and optimizing the performance of the production equipment according to the analysis result. Through sequencing the loss data, the accurate loss data is given to a user, and the user is further accurately guided to optimize the performance of the production equipment.
Specifically, as an example, the step of arranging all loss data in descending order, selecting at least one loss data for analysis, and optimizing the performance of the production equipment according to the analysis result includes: determining key loss identifiers influencing the performance of the production equipment according to the attributes of the production equipment; selecting loss identifications corresponding to the arranged loss data larger than a preset threshold value; and carrying out classification analysis on loss data respectively corresponding to the key loss identifier and the selected loss identifier, obtaining an analysis result, and optimizing the performance of the production equipment according to the analysis result.
Preferably, after step 103 and before step 104, the method further comprises: and displaying the comprehensive efficiency of the equipment and loss data associated with the comprehensive efficiency of the equipment. Correspondingly, according to the comprehensive efficiency of the equipment and the loss data associated with the comprehensive efficiency of the equipment, the performance of the production equipment is optimized, and the method comprises the following steps: and receiving an optimization instruction which is triggered by a user and comprises at least one optimization option, and optimizing the performance of the production equipment based on the loss data selected in the optimization instruction.
