Description

Technical Field

[0001] The present invention relates to the technical field of cost calculation, and in particular to a secondary equipment cost management system based on LCC cost calculation. Background Art

[0002] Cost is a value category of commodity economy and a component of commodity value. People must consume certain resources to carry out production and operation activities or achieve certain goals. The monetary expression of the consumed resources and their objectification are called costs. With the continuous development of commodity economy, the connotation and extension of the concept of cost are constantly changing and developing. From another perspective, cost can also be the price that must be paid for making a certain choice. When people give up fish and take bear's paw, "fish" is people's cost. When merchants invest, the money they pay is the cost of their investment.

[0003] The general LCC cost calculation secondary equipment cost management system on the market cannot monitor the entire process of secondary equipment from procurement to decommissioning when performing cost calculation, and it is inconvenient to optimize the entire process of secondary equipment from procurement to decommissioning, which is inconvenient for cost control. For this reason, we propose a secondary equipment cost management system based on LCC cost calculation. Summary of the invention

[0020] G A =Q A ×J A

[0021]

[0022] According to the above formula, the value of the safety mean can be obtained, and then all the safety means can be sorted to obtain a safety mean table.

[0042] In one embodiment of the present invention: the LCC calculation module can collect common calculation models, and then optimize the model according to the information of the secondary equipment, so as to obtain an LCC calculation model suitable for the secondary equipment. The LCC calculation model can comprehensively consider the time value factor and accurately calculate the full life cycle budget cost of the secondary equipment, and then transmit the processed information of the LCC calculation module to the cost analysis module.

[0043] In one embodiment of the present invention: the cost analysis module can perform a multi-dimensional analysis on the measurement structure, so as to calculate the budget cost of different secondary equipment, and can also calculate the budget cost of secondary equipment under different usage scenarios, and then compare the obtained multi-dimensional budget costs to view the budget cost differences under different equipment types and different usage scenarios. At the same time, different maintenance plans can be obtained according to different secondary equipment maintenance methods, and then the budget costs of different maintenance plans are calculated, and the information processed by the cost analysis module is transmitted to the budget management module.

[0044] In one embodiment of the present invention: the budget management module can formulate a full-cycle operation process according to the budget cost calculated by the LCC calculation model. The full-cycle operation process refers to the entire process from purchase to retirement of secondary equipment. The staff needs to operate according to the full-cycle operation process in the operation from purchase to retirement of secondary equipment, and the staff's operations need to be monitored in real time when executing the full-cycle operation process. At the same time, the staff can also urgently adjust the content of the full-cycle operation process to deal with the occurrence of different situations, and then transmit the information processed by the budget management module to the strategy optimization module.

[0048]

[0049] According to the above formula, the value of the safety mean can be obtained, and then all the safety means can be sorted to obtain a safety mean table. Then, according to the safety values ​​of different tools and the cost used to solve the problem, the maintenance cost-effectiveness is calculated, and a replacement plan is analyzed for the staff.

[0050] In one embodiment of the present invention: the maintenance perception module can obtain the secondary equipment information collected by the data acquisition module, so as to obtain the initial state information, current state information, maintenance state information and retirement state information of the secondary equipment, and then analyze the loss rate of the secondary equipment according to the initial state information, current state information, maintenance state information and retirement state information of the secondary equipment, and set a predicted time period at the same time, and predict the state change of the secondary equipment within the set time period according to the current state information and the loss rate of the secondary equipment. When the state of the secondary equipment reaches the maintenance state within the set time period, the maintenance signal will be transmitted to the preparation module.

[0051] In one embodiment of the present invention: the preparation module is used to collect weather conditions. When the preparation module receives a maintenance signal, it will analyze the time point when the status of the secondary equipment reaches the maintenance state, and then calculate the time when different maintenance personnel need to go to the maintenance location in advance according to the changes in weather conditions, so that the maintenance personnel can arrive at the maintenance location in advance.

[0052] Example 1, please refer to the attached Figure 1 The data collection module can collect all the required data through various means to meet the needs of cost estimation. When collecting data, it can give priority to collecting data from nationally certified websites to improve the authenticity of the data. When calculating costs, some factors that cause cost changes can be added to improve the accuracy of cost estimation.

[0053] Example 2, please refer to the attached Figure 1 The budget management module can monitor the entire process of secondary equipment from purchase to retirement in real time, so as to facilitate the management of secondary equipment when needed and better control the costs generated in the full cycle operation process of secondary equipment.

[0054] Example 3, please refer to the attached Figure 1When the maintenance perception module predicts the time of the next maintenance, the staff can directly input the maintenance time of the secondary equipment into the maintenance perception module. At this time, the maintenance perception module no longer needs to calculate the next maintenance time. At the same time, the maintenance time set by the staff will not cover the predicted maintenance time. When the maintenance time set by the staff is after the predicted maintenance time, the predicted maintenance time can send information reminders to the staff. At the same time, the staff can input other factors that affect the time it takes for the maintenance personnel to go to the maintenance location into the preparation module, so that the time consumed by the maintenance personnel to go to the maintenance location can be analyzed more accurately.

[0055] Specifically, through the setting of the LCC calculation module, when it is necessary to calculate the cost of the full cycle operation process of secondary equipment, the LCC calculation module can scientifically and accurately calculate the cost of the full life cycle of secondary equipment. Through the setting of the budget management module, the full cycle operation process of secondary equipment can be understood in more detail. The strategy optimization module can optimize and improve the full cycle operation process of secondary equipment, thereby forming an optimization plan, which can further reduce the cost of the next full cycle operation process of secondary equipment.

[0056] Specifically, the safety index analysis module can calculate the safety index of different secondary equipment during maintenance. At the same time, there are different maintenance plans for the same equipment. At this time, the safety index analysis module can calculate the safety index of all maintenance plans, so that the staff can understand more maintenance plans and can choose different maintenance methods when maintenance personnel are repairing, making the way of receiving fault problems more flexible.

[0057] Specifically, the maintenance perception module can predict the next maintenance time of the secondary equipment, so that preparation can be made for the maintenance of the secondary equipment in advance, increasing the effect of the maintenance of the secondary equipment. At the same time, the preparation module can calculate the time required for maintenance personnel to go to the maintenance site based on weather and other reasons, so that maintenance personnel can go to the maintenance site in advance, so that the secondary equipment can be repaired more timely.

[0058] Working principle:

[0059] First, obtain the relevant cost data of the full-cycle operation process of the secondary equipment, then establish a scientific and accurate LCC calculation model, and accurately calculate the full life cycle cost of the secondary equipment, then conduct a multi-dimensional analysis of the calculation results, and then analyze different maintenance plans for different secondary equipment and different problems, and then analyze the costs of different maintenance plans, and be able to monitor the full-cycle operation process of the secondary equipment, so that the full-cycle operation process of the secondary equipment can be managed more conveniently. When the staff executes the full-cycle operation process of the secondary equipment, they can urgently adjust the content of the full-cycle operation process of the secondary equipment. Finally, optimize the full-cycle operation process of the secondary equipment and obtain an optimization plan, so as to facilitate cost control, and then analyze the safety index of different maintenance plans, and obtain the safety index values ​​of different plans. When the secondary equipment is in use, it can predict the time when the secondary equipment needs to be repaired next time, so that it can prepare for the maintenance of the secondary equipment in advance, and can calculate the time for different maintenance personnel to go to the maintenance place, so that the maintenance personnel can go to the maintenance place in advance, so as to repair the secondary equipment in time, and the whole workflow ends here.
