The equipment cost quantification method provided by the embodiment of the application can determine the cost of each equipment in different quantification periods, and further obtain the cost of the equipment in the whole life cycle. The full life cycle cost may be used to make bidding purchases, vendor evaluations, and the like.
The specific application process of the full Life Cycle Cost (LCC) bidding purchasing application is as follows: the current national network equipment bid-recruitment purchasing bid-grading method is generally a comprehensive evaluation method, wherein the score consists of a business score value, a technical performance index score value and a bid price score value, the total score is 100, and the index proportion distribution is generally 10%, 50% and 40% respectively. The first bidder to rank the comprehensive review score is the winning bidder. The comprehensive evaluation method truly obtains certain economic benefit in the aspect of controlling equipment purchase cost, focuses on initial investment, but cannot effectively reflect the equipment life cycle cost.
And developing LCC bidding application practice, namely applying an equipment LCC portrait method, acquiring LCCs of equipment model, suppliers and other dimensions, comparing LCCs of equipment of the same type of different suppliers, and taking the LCC score of the supplier as an important factor of business targets in the material bidding score according to the principle that the lower the LCC is, the higher the score is. LCC bidding application practice specifically refers to equipment LCC promised bidding, bidding work needs to deepen continuously and cooperate with suppliers, the importance knowledge of the suppliers on the whole life cost is improved, the suppliers are required to promise to submit the relevant data of the whole life cycle cost of equipment in bidding, and the equipment LCC calculation is facilitated in a bid evaluation link.
The device LCC promised type bidding application firstly definitely confirms the range of the LCC bidding applicable device, and proposes a promised type bidding application practical scheme which takes purchasing device LCC as a principle.
Secondly, factors such as equipment operation maintenance and repair and fault cost and the like brought by equipment are fully considered, a provider is required to submit an equipment LCC promise data table aiming at the factors, and a historical provider and bidding provider equipment LCC data measuring and calculating model is established on the basis.

The specific application process of the full Life Cycle Cost (LCC) provider evaluation application is as follows: the provider evaluation means that a provider evaluation index system is established, and a proper evaluation method is selected to evaluate the provider. The national network equipment provider evaluation system mainly comprises four parts of contents including qualification, technology, after-sales and quality. The provider selection evaluation methods can be classified into qualitative methods, quantitative methods, and qualitative and quantitative combination methods. The national network equipment evaluation method is mainly a linear weighting method. The basic principle of the linear weighting method is to assign a weight to each index, and the more important the index is, the greater the weight is. The score of a provider is the sum of the scores of the indexes of the provider and the weighted products of the indexes, and the highest score is the best provider.
The LCC-based supplier evaluation method is a cost-based method in which a comparison is made between different suppliers by calculating purchase prices and various costs provided by the different suppliers, from which a supplier with the lowest cost is selected.

As an alternative to this embodiment, this alternative embodiment further optimally includes k1-k3:
k1, determining the economic life according to the cost of equipment to be quantized in different quantization periods.
The life of the equipment from its operation to its average use cost over the years is its economic life. The annual average usage cost is equal to the sum of the cumulative consumption value (depreciation) of the equipment and the costs of operation and maintenance and overhaul failures, etc., divided by the used years. And calculating the annual average use cost of the equipment to be quantized in different quantization periods, namely the cost of the whole life cycle, and determining the service life of the equipment with the lowest annual average use cost as the economic life.
The service life of the device is a result of the combined action of technical life (meaning the life of the device when it is rejected for technical reasons) and economic life (meaning the life of the device when it is rejected for economic reasons). Typically, the technical life of the device is longer than its economic life. Often, only technical life is considered when evaluating and deciding on the equipment, and in the use of today's equipment, economic factors have more and more influence on the type of equipment, and many equipment has been removed or rebuilt for another use well before the end of its technical life. Therefore, in the use of the equipment, the economic life of the equipment is measured and calculated and monitored, so that on one hand, the equipment can be prevented from being scrapped in advance before the economic life is not reached, and on the other hand, scrapping and retirement measures can be adopted for the service equipment with the super-economic life period as soon as possible, so that the operation and maintenance cost level of the equipment is reduced.
Calculating the economic life requires counting or calculating the cost of the equipment from the operation to the current use, and establishing a series (xn, yn), wherein x is the service life, and y is the total life cycle cost up to x years. Cost prediction is needed because part of the operational age cost data for a particular type of device may be missing. According to the measurement experience, when the operational period n is greater than 5, the data fitting curve is relatively accurate, so n is greater than 5. Array system The longer the time is counted, the more realistic the full life cycle cost LCC curve and LCC expression. If the data record of the equipment is not complete, the data of the equipment of the same type and the same manufacturer are preferably selected. Finally, a variation curve of annual average cost yn/xn along with xn is obtained, and the xn corresponding to the lowest point of the curve is the economic life of the equipment. By way of example, FIG. 3 provides an exemplary graph of a graph for determining economic life, wherein the horizontal axis is age, and the vertical axis is cost, and the units are primitives; the annual average cost, annual average run time cost and annual average asset consumption cost are included in FIG. 3, where N 0 The point is the economic life.
Illustratively, the present application provides an economic life calculation method for calculating an economic life by a cost average method:
the annual average cost is equal to the sum of the cumulative consumption value (depreciation) and the running cost (costs of operation maintenance faults, etc.) of the equipment divided by the year used. The corresponding year is the economic life N when the annual average cost is the lowest 0 。
Annual average costThe calculation formula is as follows:
wherein: c (C) 1 Is the initial investment cost;
project class costs for the nth year of the device;
non-project class costs for the nth year of the device;
disposal costs for the device at the end of the nth year.
And K2, when the equipment to be quantized is in an abnormal state and can be repaired, determining a maintenance scheme of the equipment to be quantized according to the current service time, the economic life and the design life, wherein the maintenance scheme is technical transformation or overhaul.

And if the equipment to be quantified is repairable, judging the service life, and determining the maintenance scheme of the equipment to be quantified by comparing the current service time, the economic service life and the design service life. The economic life is possibly smaller than the design life and possibly larger than the design life, and life judgment is carried out under different conditions according to the calculation result. The economic life is less than the design life: when the service time is less than the economic life, a overhaul scheme is selected; when the service life is between the economic service life and the design service life, the technical improvement and the overhaul can be selected; and when the service life is longer than the design service life, selecting technical transformation. The economic life is longer than the design life: when the service time is shorter than the design life, the technical improvement is selected; and when the service life is longer than the design service life, selecting technical transformation. The service life of each sectional area is not uniform, and the service life of a single area can not replace the service life of the whole line, so that the service life judgment is not carried out, and the repairable judgment result is used as a final scheme.
And K3, when the equipment to be quantized is in an abnormal state and cannot be repaired, determining that the maintenance scheme of the equipment to be quantized is technical transformation.
When the equipment to be quantized is in an abnormal state and cannot be repaired, the equipment to be quantized is directly subjected to technical transformation because the equipment to be quantized is not repairable.

The main characteristic of the technical improvement scheme is that the state of the equipment is changed after the manufacture, the cost of the original equipment cannot be used, and the equipment needs to be recalculated.
And L3, comparing the cost of each alternative scheme, and selecting the alternative scheme with the lowest cost as a target maintenance scheme.
In this embodiment, the target maintenance scheme may be specifically understood as a scheme that is finally selected to perform maintenance for the device to be quantized. Comparing the cost of each alternative scheme, selecting the alternative scheme with the lowest cost as a target maintenance scheme, and if the cost is the same, randomly selecting one alternative scheme as the target maintenance scheme or manually selecting by a staff; or other screening conditions are set for screening.
