And comparing the comprehensive index of each screw machine with the highest comprehensive index value, selecting an alternative screw machine with the difference value within the preset difference value range set by the processor, and determining the alternative screw machine as a third screw machine. Because the cost of the screw machine needs to be considered when the screw machine is selected, the processor can firstly acquire the equipment cost of the alternative screw machine with the highest comprehensive index in the alternative screw machines, then acquire the equipment cost of the selected third screw machine, compare the equipment cost of the third screw machine with the cost of the alternative screw machine with the highest comprehensive index, and determine the screw machine with the lowest cost as the target screw machine matched with the target order.
In one embodiment, a processor is provided for performing the screw selection method for a mixing station described above.
The processor may screen the original order according to a data calculation range of the screening of the mixing plant, wherein the data calculation range may be one or more of a regional range, a time range and a mixing plant model range of the mixing plant. And determining the order obtained through screening according to the data operation range as a target order, wherein the target order comprises a target metering value and target equipment metering time. The target metering value is the target nominal value of each metering device of the stirring station, and the target device metering time is the time required by each metering device to finish metering. The processor may determine a target production cumulative total for each target order based on the target metrology values, i.e., determine a current target order total production value based on each target metrology value for the metrology device.
After the processor obtains the target order and the target production cumulative total, the processor can obtain the equipment parameters of each alternative screw machine, namely the conveying speed and the accuracy value of each alternative screw machine. After the processor acquires the conveying speed and the precision value of each alternative screw machine, the efficiency matching degree of each alternative screw machine can be determined according to the conveying speed of each alternative screw machine, the metering time of the target equipment and the target production accumulation total value of the stirring station.
Firstly, the processor can verify the efficiency of the alternative screw machines, and according to the conveying speed of each alternative screw machine and the target equipment metering value, the efficiency of the alternative screw machines is verified by the formula: efficiency boundary value of screw = screw conveying speed x target equipment metering time, the efficiency boundary value of each alternative screw is determined.

After obtaining the precision boundary value of each alternative screw machine, the processor compares the precision boundary value of each alternative screw machine with the target measurement value, screens out alternative screw machines with the precision boundary smaller than the target measurement value, determines the alternative screw machines as second alternative screw machines, and determines the number of production discs when the second alternative screw machines are selected according to the target production accumulation total value, namely the actual second production accumulation total value of the second alternative screw machines. After the processor determines the actual second production running total for the second alternative screw, it may be according to the formula: screw accuracy matching degree = second production integrated value +.production integrated total value, the accuracy matching degree of the second alternative screw is determined.
After the processor obtains the efficiency matching degree and the precision matching degree of the alternative screw machines, the comprehensive index of each alternative screw machine can be determined according to the efficiency matching degree and the precision matching degree of each alternative screw machine. The processor may weight and sum the efficiency matching degree and the precision matching degree of each alternative screw machine to obtain a comprehensive index of each alternative screw machine, wherein the weight of the efficiency matching degree is a first value, the first value is determined according to the efficiency preference degree, the weight of the precision matching degree is a second value, the second value is determined according to the precision preference degree, and the sum of the first value and the second value is 1. While the first value is determined based on the efficiency preference of the alternative screw and the second value is determined based on the accuracy preference of the alternative screw. The processor may be according to the formula: comprehensive index = a% ×efficiency matching degree + b% ×precision matching degree, the comprehensive index of each candidate screw was determined. Wherein a is the efficiency preference, a% is the first value, b is the precision preference, b% is the second value, and the sum of the efficiency preference and the precision preference is 100, that is, the sum of the first value and the second value is 1. In general, the efficiency preference and the accuracy preference are the same, and are both 50.
After determining the composite index of each screw machine, the processor may determine the index value with the highest composite index of all the candidate screw machines, compare the composite index of each candidate screw machine with the highest composite index value, and determine the screw machine with the difference within the preset threshold as the third candidate screw machine. Since the efficiency and accuracy of the screw are considered when selecting the screw, the cost of the screw is also considered. The processor may first determine the equipment cost of the candidate screw machine having the highest overall index among the candidate screw machines, and after acquiring the equipment cost of the third candidate screw machine, compare the equipment cost of the third candidate screw machine with the cost of the candidate screw machine having the highest overall index, and determine the screw machine having the lowest cost as the target screw machine that matches the target order. Thus, the most suitable screw machine can be selected according to the three aspects of efficiency, precision and cost of the screw machine.
By the technical scheme, equipment parameters of the alternative screw machine and a target order of production required by the stirring station are acquired. And aiming at the target order, efficiency checking is carried out on the alternative screw machines, screw machines with proper efficiency matching degree are selected, accuracy checking is carried out on the alternative screw machines, and screw machines with proper accuracy matching degree are selected. After the efficiency matching degree and the precision matching degree of the alternative screw machines are obtained, the comprehensive index of each screw machine can be determined according to the efficiency matching degree and the precision matching degree. Because the cost of the screw machines is also required to be considered, the screw machines with the lowest cost are selected while the comprehensive index of the screw machines is considered, and the screw machine with the highest comprehensive index is selected from the lowest cost. So that for a target order, the best screw machine can be selected from efficiency, accuracy, and cost. The technical defect that only the efficiency of the screw machine is considered when the engineering is selected according to the manual experience in the prior art is avoided.
