Detailed Description
The present invention will be further explained below.
As shown in the figure, the method comprises the following specific steps:
A. establishing an SPN model of an oil and gas pipeline emergency repair scheme: establishing an SPN model by an SPN method according to an oil and gas pipeline emergency repair process; storing the characteristics of all approach road construction methods, the characteristics of all emergency repair area construction methods, the characteristics of all maintenance and emergency repair operation methods and the characteristics of all ground disaster methods in various event types into a server for calling the SPN model; the method specifically comprises the following steps:
the random petri net (SPN) can analyze the system performance, can well process the dynamic process of information transmission, and can perform mathematical description on multitask and feedback loop execution. The careadam Petri proposed a Petri net in 1962, which is a tool for system analysis and modeling, and can be used for describing and processing asynchronous, distributed, parallel and other information. In the beginning of the 80 th 20 th century, Molly introduced the implementation delay of the transition into the system, and correlated the corresponding implementation rate for each transition in the Petri network, thereby constructing a Stochastic Petri Network (SPN) of the system.
Defining: the stochastic Petri net is a six-tuple:
SPN＝(P,T,F,W,M,λ)
wherein: (ii) P ═ P1,P2,P3,…,PmM is a positive integer, representing a non-empty finite set of positions, denoted by small circles "°; ② T ═ T1,t2.t3,…,tnN is a positive integer representing a non-empty finite set of transitions, the transition being represented by the symbol "□"; ③ of
Representing a non-empty finite set of transition input arcs and transition output arcs, and representing a flow relation between positions and transitions; w is a weight function, each input arc or output arc is weighted, W (p, t) or W (t, p) represents the weight of a directed arc directed to t by p or p by t; m is a mark which represents the distribution of the mark at each position in the petri net, and the mark represents the resource or information in the system. M0 is an initial identification; λ ═ λ { [ λ ]1,λ2,λ3…λkAnd represents a set of transition real-time rates.
The SPN modeling can describe the time sequence of various activities in the emergency rescue process of the oil and gas pipeline and process the links of generation and transmission of information in the emergency rescue process. The mode that the SPN is used for describing the system structure mainly represents the process of generating or changing information and other resources in the emergency rescue process by using the position and the transition, namely each state of the system in the emergency rescue process; and defining each position and the transition label by adopting an SPN model according to an oil and gas pipeline emergency repair process, thereby establishing the SPN model of the oil and gas pipeline emergency repair scheme.

TABLE 1 description of position and transition
First, effectiveness analysis of oil and gas pipeline accident emergency rescue system
And judging whether the emergency system SPN meets the boundedness and the effectiveness by a T-invariant method. T-invariant:
due to the boundedness of the Petri net, the N is an essential condition of the structure bounded net, namely that a positive integer vector X exists, so that AX is 0, and the condition is satisfied due to the value of the T-invariant, so that the emergency treatment model is the bounded Petri net.
When the vector component of the T-invariant is 1, the corresponding transition is triggered, and when the vector component is 0, the corresponding transition is not triggered.
Reflecting the flow relationships in different situations, e.g.
Indicating that transitions T1, T2, T3, T4, T5, T6, T7, T8 are triggered, reflecting a trigger sequence that initiates an emergency procedure. It can thus be seen that all transitions are likely to be triggered, all tasks can be performed, and the model is a live Petri net.
Simulation analysis of emergency rescue process efficiency of oil and gas pipeline accident
According to the steps of the SPN performance analysis method introduced above, the oil and gas pipeline emergency rescue SPN model is firstly expanded into a strongly-communicated workflow network, namely, each position and transition in the SPN model requires input and output conditions, and an appropriate transition or position needs to be added manually, such as t10 in FIG. 6. Then, according to the conversion rule from the SPN model to the markov chain, a markov chain isomorphic with the SPN model is constructed, as shown in fig. 7.
The initial identity M0 of the SPN model is (1,0,0,0,0,0,0,0,0,0), indicating that there is a marker in position P1. There are no marks in other positions. Specifically describing the emergency state of the gas pipeline accident as follows: the gas pipeline has an accident, and no other related action is available. The meaning of the other identifiers is similar to the above explanation and will not be described in detail here. The set of everything identities reachable from the initial identity is denoted as R (M0) ═ M0,M1,M2,M3,M4,M5,M6,M7,M8,M9And (5) expressed by a matrix as:
λ represents the number of times that transitions occur in the SPN model per unit time, i.e., the occurrence rate.
Obtaining a transfer rate matrix Q of the Markov process according to the existing MC:
substituting the transfer rate matrix Q into the characteristic equation of the Markov chain model to obtain the following relational expression between the state probabilities.
A stable probability P [ Mi ] ═ xi can be obtained for each reachable identity, with the results shown in table 2.
TABLE 2 reachable identity stability probability
The performance index of the model can be calculated by adopting the stable probability value in each state identifier: probability density function of position, utilization rate of transition and average execution time of system.
The location busy probability density function may describe a location busy level. In the natural gas pipeline accident emergency rescue SPN model, the probability of busy position actually refers to the probability of busy state in each rescue stage. The transition utilization characterizes the time occupancy of each activity throughout the emergency response.
