Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for determining a project engineering process plan for a high pile wharf, it should be noted that the steps illustrated in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be executed in an order different from the order illustrated.
Fig. 1 is a flowchart of a method for determining a high-pile wharf engineering construction process scheme according to an embodiment of the invention, and as shown in fig. 1, the method includes the following steps:
and S102, acquiring engineering information of the high-pile wharf engineering.
In step S102, the project information of the high pile wharf project includes at least one of: and the subsection of the high-pile wharf engineering is divided into project information, construction process information and construction resource information. Optionally, the construction process information includes, but is not limited to, a high pile wharf type, wherein the high pile wharf type includes, but is not limited to, a beam slab type and other types; the construction resource information includes, but is not limited to, information about the type of equipment used during construction, work efficiency, work type, and construction team.
In an optional embodiment, the simulation model may obtain engineering information of the high-pile wharf engineering, where the simulation model is a model of a typical high-pile wharf construction process established by using a discrete system simulation technique, and the model may simulate each subsection construction engineering of a detailed construction process of the high-pile wharf under a given construction scheme and resource constraints, reflect characteristics of the subsection construction engineering, and may output information of a construction period, construction cost, and the like of the construction scheme for quantitative analysis. Meanwhile, the simulation model can comprehensively and definitely reflect the interrelation, the mutual restriction and the interdependence among all the construction processes, and reflect a key route in a plan with various processes and complex relations, so that managers can concentrate on catching the main contradiction to ensure the construction period. By utilizing the starting time of each construction process reflected by the simulation model, resources can be better equipped and utilized, so that the aim of reducing the cost is fulfilled. In the process of executing the high-pile wharf project, the influence degree of delay of a certain subsection construction project on the completion time of other subsection construction projects or the total construction period can be predicted, and measures can be taken to adjust as soon as possible. The application of the simulation model provides powerful support for engineering construction planning and intelligent decision making of the high-pile wharf. In addition, the simulation model of the high-pile wharf project can be established by programming in a JAVA programming language.
Optionally, the manager establishes the simulation model through the computer, and inputs the engineering information of the high-pile wharf project through the input device of the computer, for example, the manager inputs the wharf type used in the construction process of the high-pile wharf project, the type of the adopted equipment, the work efficiency, the work type and the like to the simulation model through the keyboard.
And S104, simulating the construction process of the high-pile wharf project based on the project information to obtain the initial construction process scheme information of each subsection project construction project in the construction process.
In step S104, the initial construction process recipe information includes at least one of: the starting time, the ending time, the resource intensity, the total construction period and the key route of the construction process.
Optionally, after obtaining the engineering information of the high-pile wharf engineering, the simulation model simulates the construction process of the high-pile wharf engineering, and the discrete system simulation technology and the cyclic network technology are adopted to simulate the construction process, so as to obtain the start time, the end time and the resource strength of each construction process in the construction process, and the total construction period and the key route determined in the construction process. The method can regard resources involved in the construction process as flow units, divide the flow units into working and queuing waiting states according to the queuing theory, simultaneously regard the whole construction process as a dynamic flow process of the flow units, establish a circulating network model for the construction process of an engineering object, perform simulation calculation on a computer, and simulate a construction period progress index under different resource configurations and construction plans. And then, comprehensively considering the construction progress of the high-pile wharf engineering, and performing initial assignment on the engineering information in the simulation model by using an expert experience method and an engineering comparison method to form initial information of each construction process.
In addition, it should be noted that the simulation technique can be divided into a continuous system simulation technique and a discrete system simulation technique according to the relationship between the system state change and the time. In the high-pile wharf engineering construction system, the state changes of the ship equipment, the pile caps, the beam lattices and other entities all occur at discrete time points and are discontinuous in time, so that a discrete system simulation technology is adopted in the application.
The simulation of the construction process of the high-pile wharf engineering is realized through the step S104, the relevant information in the construction process of the high-pile wharf engineering is comprehensively considered in the simulation process of the construction process, and the construction process scheme information of each subsection construction engineering is obtained according to the relevant information, so that the accurate analysis of the high-pile wharf engineering is realized.
And S106, optimizing the construction process based on the initial construction process scheme information to obtain the construction process scheme of each subsection project construction project.
In the process of the process information of each construction process obtained through the simulation model, the start time of the construction process on the non-critical route is the earliest start time of the construction process, so that the construction is concentrated in some time intervals, which causes excessive resource intensity or large difference of the demand of the resources in each time interval. If the resources are not optimized in a balanced manner, a phenomenon of labor rescue or work loss can be caused in the construction process, and the material supply can be disconnected or excessive, so that the smooth construction is influenced, and unnecessary waste of manpower and material resources is caused. Therefore, after the initial process information of each construction process is obtained by the simulation model, it is necessary to perform intensity statistics on the initial process information and perform resource balance optimization. Optionally, the starting time of the construction process of the non-critical route may be adjusted by the maneuvering time difference of each construction process to achieve balanced allocation of resources. The resource balance optimization in the high-pile wharf project aims to solve the problem of resource balance consumption under the condition of a certain construction period, namely the problem of 'construction period limitation and resource balance'.
Optionally, in the present application, a "peak clipping and valley filling method" is used to perform resource intensity equalization optimization, and the method achieves the purpose of gradually reducing the maximum resource intensity and reducing the fluctuation of the dynamic curve by adjusting the start time of a part of the construction process within the maximum resource intensity period based on the maximum intensity value of the dynamic curve of the resource.
Based on the schemes defined in the above steps S102 to S106, it can be known that, by analyzing and optimizing the construction process scheme information of each subsection of the high-pile wharf project, after the project information of the high-pile wharf project is obtained, the construction process of the high-pile wharf project is simulated based on the project information to obtain the initial construction process scheme information of each subsection of the construction project in the construction process, and then the construction process is optimized based on the initial construction process scheme information to obtain the construction process scheme of each subsection of the construction project.
It is easy to notice that, in the application, the relevant information in the construction process of the high-pile wharf engineering is comprehensively considered, and the construction process scheme information of each subsection construction engineering is obtained according to the relevant information, so that the accurate analysis of the high-pile wharf engineering is realized. In addition, in order to further improve the accuracy of analysis, after the construction process scheme information of each subsection construction project is obtained, each subsection construction project is further optimized, and then an optimal construction scheme is obtained.
Therefore, the scheme provided by the application achieves the purpose of predicting and analyzing the high-pile wharf engineering, the technical effect of improving the accuracy of prediction and analysis of the high-pile wharf engineering is achieved, and the technical problem that the existing method for predicting and analyzing the construction process of the high-pile wharf engineering according to construction experience causes inaccuracy of the construction process scheme of the high-pile wharf engineering is solved.
In an optional embodiment, after obtaining the engineering information of the high-pile wharf engineering, the simulation model simulates the construction process of the high-pile wharf engineering based on the engineering information to obtain the initial construction process scheme information of each subsection construction engineering in the construction process. Specifically, the simulation model configures the construction process flow of the high-pile wharf project according to the project information to obtain a configuration result, divides the construction implementation mode of the high-pile wharf project on the spatial arrangement according to the project information to obtain a division result, determines the construction sequence of each subsection construction project according to the configuration result and the division result, obtains resource information corresponding to each subsection construction project, and finally simulates the construction process according to the construction sequence and the resource information to obtain initial construction process scheme information of each subsection construction project.
In the above process, the resource information includes at least one of: device information, and manual information. The device information includes, but is not limited to, a device type, a maximum number of devices, and a minimum number of devices; the manual information includes, but is not limited to, work category maximum number, and work category minimum number.
In addition, the high-pile wharf engineering is divided, which mainly means that the high-pile wharf engineering is divided in spatial arrangement when the construction engineering is organized in flowing water construction, wherein the high-pile wharf engineering can be divided into a structure section, a construction section and a surface layer strip.
Optionally, the structure section is in the work progress, and high stake pier major structure divides into a plurality of structure sections that the structure is similar, and wherein, the construction of pile foundation uses the structure section to construct as unit order. The construction section is a division concept of horizontal construction of upper structural parts (e.g., pile caps, beam lattices, cast-in-place nodes, panels, and slab joints) within a structural section, and one structural section may be divided into a plurality of construction sections for construction, which are advanced in a horizontal direction. The construction process of pile caps, beam grids (including longitudinal beams, cross beams, track beams and ship leaning components), cast-in-place nodes, panels and plate joints is promoted by a typical construction section. The construction of the surface layer strip is not included in the category of a typical construction section, but the construction process of the surface layer strip is similar to the concept of the typical construction section, the surface layer is divided into a plurality of strips, and each part is constructed by the flow of the construction project.
Optionally, fig. 2(a) to 2(e) show a flow chart of an optional construction process, where fig. 2(c) is a schematic diagram of a basic construction process, fig. 2(d) is a schematic diagram of a pile foundation and soil retaining structure construction process, and fig. 2(e) is a schematic diagram of a cast-in-place process. As can be seen from fig. 2(a) to 2(e), in the horizontal plane, the construction direction is sequentially constructed in units of structural sections from the wharf end until completion. The construction sequence of the single structural section on the vertical surface is as follows: pile foundation → pile cap, beam lattice, node, panel, plate joint construction with construction section → surface layer construction → installation of wharf appurtenances and others. The superstructure in the structure section can divide into sea and land both sides by oneself, and every side is under construction alone, can start to promote the construction to the other end from the one end of structure section, also can start to promote the construction to the pier centre from the both ends of structure section. The resources involved in the construction process comprise ship equipment, human resources and template resources. Generally, the more resources are allocated, the shorter the construction period; the less the resource is allocated, the longer the construction period.
Further, after the initial construction process scheme information of each subsection project construction is obtained, in order to improve the accuracy of analysis and save resources, the simulation model optimizes the construction process based on the initial construction process scheme information to obtain the construction process scheme of each subsection project construction. Specifically, the simulation model firstly obtains initial process information of a construction process corresponding to each preset time period, then determines a resource intensity value in each preset time period according to the initial process information, determines a maximum resource intensity value from the resource intensity values in the preset time periods, and finally optimizes the construction process according to the maximum resource intensity value and the maximum target intensity value and preset rules.
Optionally, the optimizing the construction process according to the maximum resource intensity value and the maximum target intensity value and according to a preset rule includes: under the condition that the maximum value of the resource intensity in the current preset time period is larger than the maximum value of the target intensity, determining a first construction process in which the resource intensity value in the current preset time period is minimum; when the number of the first construction processes is one, postponing the construction starting time corresponding to the first construction process to the next preset time period; and under the condition that the number of the first construction procedures is multiple, acquiring adjustable time differences corresponding to the multiple first construction procedures, and optimizing the construction process according to the adjustable time differences.
Wherein, the step of optimizing the work progress according to the adjustable time difference comprises: acquiring adjustable time differences corresponding to a plurality of first construction processes, and determining a second construction process with the maximum adjustable time difference; when the number of the second construction processes is one, postponing the starting time corresponding to the second construction process to the next preset time period; and under the condition that the number of the second construction processes is multiple, acquiring the maximum value of the first resource intensity, and postponing the starting time of the corresponding second construction process when the maximum value of the first resource intensity is smaller than the maximum value of the target intensity until the next preset time period.
Specifically, the simulation model detects the construction process being constructed and detects the construction strength of the construction process being constructed each time Δ T (namely, a preset time period) is advanced in the simulation time, then counts the engineering quantity in the preset time period and the resource strength value in each preset time period, draws an initial resource strength dynamic curve graph, and determines the maximum resource strength value Rmax1 according to the resource strength dynamic curve graph.
Further, the simulation model compares the resource intensity maximum value Rmax1 with the target intensity maximum value Rmax 2. Specifically, the simulation model selects a non-critical process which is positioned in the preset time period and can be postponed to start after the preset time period according to a priority postponing rule from back to front for resource intensity peaks of all preset time periods which are larger than the maximum value Rmax2 of the target intensity, and postpones the non-critical process to start after the preset time period, so that the resource intensity peaks are cut down once, and the resource intensity valleys are filled up once correspondingly. The simulation model then modifies the time parameters (e.g., start time, end time) in the corresponding construction process, and repeats the above process until the maximum resource strength value cannot be reduced.
In addition, the "priority deferral" rule may include: preferentially postponing the construction process with low resource strength; under the condition of the same resource strength, the construction process with large adjustable time difference is delayed preferentially; the adjusted peak intensity of the resource is lower than the peak value of the target resource.
It should be noted that the first maximum resource strength value may be obtained by any one or more of the following manners:
acquiring the starting time corresponding to each second construction procedure, and postponing the starting time to the maximum value of the corresponding resource strength in the next preset time period to obtain the maximum value of the first resource strength; and/or adjusting the resource allocation corresponding to each second construction process to obtain an adjusted second construction process, wherein the maximum value of the resource intensity corresponding to the adjusted second construction process is the maximum value of the first resource intensity.
In addition, before the construction process is optimized according to the maximum resource intensity value and the maximum target intensity value and according to a preset rule, the maximum target intensity value can be determined in any one of the following manners: determining a maximum value of the target intensity according to a product of the maximum value of the resource intensity and a preset weight, wherein the preset weight is a positive number less than 1, for example, 97% of the maximum value of the resource intensity may be the maximum value of the target intensity, and 97% is the preset weight; or determining the maximum value of the target intensity according to the difference value between the maximum value of the resource intensity and a preset value, wherein the preset value is a positive number.
In addition, it should be noted that the decision of the high-pile wharf construction project is a multi-objective optimization problem. The multi-objective optimization problem is that under the condition that the resource allocation of the process is not fixed (for example, the resource allocation quantity is not unique or within a range, and the work in the project has a combination form of various working hours and resource demand for selection), the preset targets of cost and construction period are finally achieved by adjusting the resource allocation of the construction process and the work starting time of the construction process. In the method, the optimization model is solved by adopting a genetic algorithm, so that the intelligent decision of the construction process is realized.
Optionally, fig. 3 shows a flow chart of a method for determining an optional construction procedure of a high-pile wharf project, and as can be seen from fig. 3, the method mainly includes four stages, namely, a project and resource information entry stage, a construction planning stage, a construction network generation stage, and a simulation and optimization stage. In the engineering and resource information input stage, a user selects a high-pile wharf type through a computer and then inputs branch project information, ship equipment and manual information of the wharf. In the construction planning stage, the simulation model divides the construction project into a structure section, a construction section and a surface layer strip, and selects a subsection project process flow to further determine the construction equipment and the manual information of each construction process. In the stage of generating the construction network, the simulation model generates a network diagram of the construction processes according to the process flows of the sub-engineering, wherein the network diagram of the construction processes is a directed network relation diagram among the construction processes. In the simulation and optimization stage, the simulation model optimizes the construction process to obtain an optimization result. Specifically, under the condition that the process resource allocation is fixed, the minimum value of the total resource input amount is calculated, so that the construction cost is minimum; under the condition that the process resource allocation and the total resource input amount are fixed, reasonably arranging the construction sequence to ensure that the total construction period is shortest; and under the conditions that the resource allocation of the process is variable, the total resource investment is fixed or the total resource investment is not limited, performing multi-objective optimization. And finally, generating a construction plan according to the optimization result, wherein the construction plan comprises but is not limited to a construction period, a key route, a resource allocation plan, a process construction schedule, a resource input plan and the like.
Therefore, according to the scheme provided by the application, the computer simulation technology is applied to the construction planning process of the high-pile wharf, the special characteristics of the high-pile wharf engineering can be met, the method has strong pertinence, and the actual problem in the construction process planning of the high-pile wharf can be better solved.
