[Abstract]:In recent years, with the rapid development of the national economy and the gradual opening of the aviation market, the air traffic volume and flight range are expanding day by day, and the work of aviation safety management is becoming more and more important. All kinds of rules and procedures and other human factors, organization and management factors, but the most critical factor is "people". To strengthen the management of "people", the key lies in the management of key technical personnel involved in the flight safety chain. In this paper, the key technical personnel of cabin service and operation control department, cabin crew and flight dispatcher, are taken as the research object. From the safety point of view, the problems of cabin crew's model license planning and a series of problems related to flight dispatcher's production planning are studied. The main contents of the paper are as follows:
Firstly, based on the maximum degree of production security and the goal of balancing the per capita income of the flight attendants, this paper studies the problem of aircrew type licensing planning and determines the number of crew members for each type licensing combination under the conditions of meeting the production task requirements and limiting the number of crew service types. This paper divides the problem of crew licence planning into two parts: crew demand estimation and crew licence allocation optimization, and mainly studies the problem of crew licence allocation optimization.
(1) Optimizing the allocation of crew type licences with limited number of crew service aircraft under the maximum degree of production security. Production security is the evaluation index of production operation security for the scheme of crew type licences.
(2) Optimizing the allocation of crew type licences to meet the constraints of production security and the number of crew service aircraft under the goal of per capita income balance.
Two, for the flight dispatchers, the main contents of the study are:
(1) Characterize the workload of flight dispatchers, get the peak time of dispatching workload, and analyze the flight composition with high peak load dispatching seats, so as to provide support for the rational allocation of routes.
(2) The work intensity of the assigned and released seats is represented by the workload of the unit time interval of the seats. The task scheduling problem of the assigned and released seats based on the minimum peak load is studied, and the work schedule with the minimum peak load of the released seats is obtained, which provides decision support for the rational allocation of the released tasks between seats.
(3) Given the set of dispatched and released seats, the task allocation problem between dispatched and released seats with the minimum peak load and the minimum total load is studied.
The methods and main conclusions adopted in this paper are as follows:
Firstly, in order to solve the problem of crew licence allocation optimization under the objective of production security, this paper proposes a solution construction algorithm, which can directly construct the optimal solution for a certain type of problem, and obtain the feasible solution with the maximum difference of 1/n0 from the optimal solution for other types of problems. Here N0 is the minimum number of demand for different types of aircraft production. Value.
Secondly, in the problem of optimizing the licence allocation of cabin crew with the maximal production guarantee and balanced per capita income, this paper abstracts the problem into a one-dimensional packing problem in which each box contains the same number of items, but the types of items are different. A greedy algorithm based on LPT algorithm is proposed and K < 2 is obtained. The optimal solution is given; k2, the worst case performance ratio is 2-M-1. Here, K is the number of type licenses available to the crew, and M is the total number of crew members.
Thirdly, in the research of task scheduling for dispatch and release seats based on minimum peak load, this paper describes the problem as a single machine scheduling problem with priority task scheduling. Each task has an arrival time, deadline and processing time. The goal is to maximize the peak load of the machine without delay in completing the task. Small, and put forward an effective algorithm, and proved that the algorithm of the task scheduling plan is the best arrangement.
Fourthly, two VNS algorithms, VND and RVNS, are used to solve the task allocation problem between dispatch and release jobs. In the process of solving the problem, two kinds of domain selection methods, insertion and exchange type jobs, are defined and used in the domain search algorithm. The modified parallel machine scheduling heuristic algorithm proposed by Vazirani is used to solve the problem. Finally, we use the flight release data of an airline to evaluate the effectiveness of our algorithm. The results of a case show that both VND and RVNS can provide stable and good results.
The main innovations of this paper are as follows: firstly, for the first time, the problem of cabin crew licence allocation is modeled, and an efficient algorithm (solution construction algorithm and greedy algorithm based on LPT algorithm) is designed to solve it; secondly, the task allocation problem of flight dispatcher is modeled for the first time, and the optimal algorithm is designed to solve it.
