Description
(I) in the field of technology
The invention provides an equipment system guarantee scheme optimization method based on a mixed heuristic algorithm, which aims at the geographical position and the layout form of an equipment system and generates an equipment system guarantee scheme under the condition of ensuring facility distribution constraint, service constraint, support personnel constraint and support time constraint according to the support requirements of each equipment. The method generates a feasible guarantee scheme for the complex equipment system through a hybrid heuristic algorithm so as to guarantee the reliable operation of the equipment system. The invention belongs to the technical field of reliability engineering.
(II) background of the invention
The modern war is a combined war integrating five places of land, sea, air, sky and electromagnetism, and is essentially the confrontation of an equipment system to the equipment system. Under the condition of combined operation, the problem of guaranteeing an equipment system is more complex and outstanding, and in order to fully exert the operation efficiency of the equipment system, related guarantee plans, transportation scheduling of spare parts, planning of guarantee schemes and the like become one of hot topics in recent years. According to the statistics of equipment system reports published in 2010, the operating and maintenance costs of an equipment system typically account for about 20% -35% of its life cycle. The high-efficiency guarantee scheme can reduce the operation cost of the complex equipment system, improve the availability and the operational efficiency of the complex equipment system and play a decisive role in modern war.
For a complex equipment system, due to the badness of the operating environment and the strong timeliness of guaranteeing the work, the following constraints are generally considered in the guarantee scheme: 1) and ensuring the working time window. In view of the performance and safety of the transport equipment, the security work can only be performed within a time window that meets the transport conditions. Meanwhile, due to the fact that the operation environment changes frequently, the working time window is guaranteed to be discrete; 2) and the resource availability is guaranteed. In consideration of various heterogeneous elements in a complex equipment system, the types of special/general guarantee equipment, spare parts, guarantee personnel and the like are more. Based on the guarantee scheme, if various guarantee resources can complete the guarantee task of the equipment, the guarantee operation can be carried out, otherwise, the waiting is needed; 3) resource transportation constraint is guaranteed. The size and weight limits of transportation equipment (such as vehicles, ships, airplanes and the like) cannot be exceeded by various security resources in the transportation process; 4) provisioning resource allocation constraints, taking into account that complex equipment architectures are typically distributed over multiple discrete areas, and provisioning is typically provided by multiple maintenance sites. There is usually a defined relationship between the constraint relationship between the security site and the system operating area. Therefore, in consideration of the above constraints, optimization of a guarantee scheme of a complex equipment system is a complex problem to be solved urgently.
Disclosure of the invention
The invention provides an effective global guarantee scheme optimization method under the condition of considering the constraint in the guarantee process of a complex equipment system, and the purpose and the problem to be solved are as follows: the equipment in a complex equipment architecture is usually distributed in w discrete areas, and it has b maintenance sites to provide support services for it at the same time, where w and b form a multi-mapping relationship. How to utilize the guaranteed resources in the b maintenance sites is a problem to be solved by the invention, and a complex equipment system guarantee scheme of w areas is generated under the conditions of meeting the requirements of guaranteeing a working time window, guaranteeing resource availability, guaranteeing resource transportation and guaranteeing resource allocation constraint.
The invention provides an equipment system guarantee scheme optimization method based on a mixed heuristic algorithm, which aims at the mapping relation between an equipment system and a guarantee site, the geographical position of the equipment system and the layout form of the equipment system, and generates an equipment system guarantee scheme under the conditions of guaranteeing facility distribution constraint, service constraint, support personnel constraint and guarantee time constraint according to the guarantee requirements of each equipment. The invention generates a feasible guarantee scheme for a complex equipment system by a hybrid heuristic algorithm, which comprises the following specific steps:
step (1): describing the requirements of the equipment guarantee model according to the state of the equipment;
step (2): describing each guarantee site according to the guarantee resource condition required by the equipment;
and (3): optimizing constraint modeling of a guarantee scheme;
and (4): evaluating the cost of a complex equipment system guarantee scheme;
and (5): generating a specific complex equipment system guarantee scheme according to the relevant constraint conditions;
in the step (1), according to the state of the equipment, the requirements of the equipment guarantee model are described in a specific implementation process as follows: determining the number u of the equipment to be maintained and the required guarantee time m in the maintenance period according to the specific state of each equipment in the complex equipment systemuAcceptable latest guaranteed timeNumber and type of required security personnelNumber of spare parts requiredAnd the like.
In the step (2), according to the guaranteed resource condition required by the equipment, the concrete implementation process of each guaranteed site is described as follows: in the process of guaranteeing a complex equipment system, a plurality of guarantee sites usually exist, and a fixed mapping relationship exists between each site and guarantee equipment:
for each guarantee station, the number of the transport equipment contained in the guarantee station is determined according to the position and the requirement of the guarantee station(For the type of transport equipment), the number and types of various security personnelMaximum number of persons in transport facilityMaximum guaranteed resource quantity that the transport equipment can bearAvailability status of security personnel(The support personnel representing the category γ are in a usable state), the usable state of the transport equipment(Representative categoriesIs in a usable state).
In the step (3), the concrete implementation process of the guarantee scheme optimization constraint modeling is as follows: according to the requirements of a complex equipment system, the constraints of guaranteeing a working time window, guaranteeing resource availability, guaranteeing resource transportation, guaranteeing resource allocation and the like need to be met in the process of guaranteeing. Meanwhile, if the guarantee process exceeds the guarantee time which can be accepted by the equipment at the latest, corresponding punishment cost is generated.
Constraint (1): the number of the transportation equipment providing the guarantee service for the equipment system does not exceed the sum of the number of the transportation equipment of all the guarantee sites;
constraint (2): in any guarantee period, the transport equipment does not exceed the maximum transport equipment number of the guarantee station;
constraint (3): in any guarantee period, the number of guarantee personnel on the transportation equipment does not exceed the maximum bearing capacity of the transportation equipment;
constraint (4): the same transportation equipment can not provide guarantee service for equipment in a plurality of areas at the same time;
constraint (5): the equipment only needs to carry out a guarantee task once in a guarantee period;
constraint (6): the route from equipment i to equipment i' can only pass once within the guarantee period;
constraint (7): all transport equipment can start from any security station and return to any security station after the maintenance task is completed. Meanwhile, during the guarantee period, the system can move to and fro to the guarantee station for many times;
constraint (8): if the transportation equipment needs to stay in place during the guarantee period, the starting point and the end point of the transportation equipment are the same equipment;
constraint (9): the system is used for scheduling the guarantee scheme and maintaining the guarantee working time window;
constraint (10): the arbitrary guarantee working time window must be greater than the guarantee time required by the equipment and the sum of the time for guaranteeing personnel and guarantee equipment to load and unload from the transportation equipment;
constraint (11): the time for the transport equipment to leave the guarantee site is set to 0;
constraint (12): the time difference between arrival at equipment i and equipment i' is related only to the transport time and loading and unloading time of the transport device;
constraint (13): after reaching the equipment i', the number of various security personnel on the transportation equipment changes.
In the step (4), the cost evaluation of the complex equipment system guarantee scheme is specifically implemented as follows: for the guarantee scheme of a complex equipment system, the cost mainly comprises three parts: the personnel cost, the punishment cost and the transportation cost are guaranteed. It should be noted that, since the guarantee requirement of each equipment in the guarantee period does not change, the required guarantee resource cost is also a fixed value, so it is not considered in the cost evaluation step. The cost evaluation correlation formula is as follows:
wherein, CtecTo guarantee personnel expenses; cpenPenalty cost; ctraFor transportation costs.
In the step (5), according to the relevant constraint conditions, a specific complex equipment system guarantee scheme is generated, and the specific implementation process is as follows: for the problem of optimization of the guarantee scheme of a complex equipment system, the problem can be divided into two subproblems for analysis. Firstly, because the equipment area and the guarantee site have a many-to-many mapping relation, the corresponding relation between each transport device and the guarantee area under the initial condition needs to be determined under the condition of satisfying the constraint; secondly, on the basis of guaranteeing the corresponding relation, feasible guarantee resources and guarantee personnel distribution paths are designed and generated, and finally a complete guarantee scheme is generated.
