Description

Intelligent dispatching method and system for port transportation grains
Technical Field
The invention belongs to the technical field of port bulk grain transportation, and particularly relates to an intelligent dispatching method and system for port bulk grain transportation.
Background
Bulk grain: in the operations of loading, unloading, transporting, storing and the like in the grain circulation process, granular raw grains appear in a bulk form.
In the process of loading, unloading, transferring and storing bulk grain in ports, the amount of bulk grain is reduced directly or indirectly due to factors such as scattering and leakage, dust emission, water wetting, crushing, insect and mouse damage, heating, mildew, pollution and the like.
The package and transportation of grains make the cost of package and manpower loading and unloading higher, which results in increased operation cost and can not meet the four-dispersion requirements of bulk, bulk transportation, bulk unloading and bulk storage. However, as the grain producing areas are widely distributed and have more receiving, storing, loading and unloading links, the grain packing transportation still occupies a larger proportion, the grain packing and bulk grain logistics mode coexist, and the grain logistics bulk advantage cannot be fully exerted. The construction of the specialized technical matching equipment for the fortification is imperfect, the requirement of the fortification operation cannot be met, compared with the grain production cost, the conventional grain transportation cost is too high and occupies most of the grain logistics cost, so that a technical scheme is needed in urgent need from the transportation side or the port loading and unloading side, the transportation efficiency is improved, and the transportation cost and the labor cost are reduced.

As shown in fig. 1, an embodiment of the present invention provides an intelligent dispatching method for port transportation grains, including:
step 101, acquiring all transit grain storages and mutual transportation paths which are near a port grain storage and can transport bulk grain for the port grain storage, performing topological operation on all transit grain storages and transportation paths to generate a bulk grain transportation directed graph, wherein the vertex of the bulk grain transportation directed graph is the port grain storage, traversing the bulk grain transportation directed graph, and finding out all paths from each transit grain storage to the port grain storage;

After the required bulk grain quantity is sent to the next transit grain storage, continuing to traverse until the required bulk grain quantity is sent to the port grain storage. For example, when bulk grain required for transporting from a middle grain warehouse is not only considered, but also considered, if a certain item of data exceeds a standard, for example, the temperature exceeds the highest temperature that grains can be stored, the grains may be spoiled, if the bulk grain is not transported timely, so that the purpose of selecting the middle grain warehouse can be better achieved by integrating indexes of the grains and transport paths of the middle grain warehouse, and when bulk grain is transported from one middle grain warehouse to the next middle grain warehouse, the bulk grain needs to be traversed, because the bulk grain needs to be transported from one middle grain warehouse to the next middle grain warehouse, during the time, the storage parameters of the corresponding bulk grain in other middle grain warehouses are likely to change, even the corresponding storage standard is not met, at this time, the bulk grain transported to the next middle grain warehouse may be required to continue to traverse, and the risk of spoiling the bulk grain generated by transporting from the middle grain warehouse which does not meet the storage standard can be greatly reduced.
The above transportation path searching model is provided that the number of bulk grains stored in the bulk grain storage must be equal to the number of bulk grains required by the port grain storage in the transportation directed graph, because in the actual operation process, the bulk grains stored in the vicinity of the port grain storage are generally equal to the bulk grains required by the port transportation, but one case is that the vicinity of the port grain storage is equal to the bulk grains required by the port transportation, and as shown above, the other case is that the vicinity of the port is equal to the bulk grains required by the port grain storage, and the bulk grains stored in the vicinity of the port are not equal to the bulk grains required by the port grain storage, so that the addition of the bulk grains stored in the vicinity of the port is required to meet the bulk grain required by the port storage, and the following steps are required:
specifically, when the bulk grain stored in the storage of the transfer grain near the port can meet the quantity of the bulk grain required by the storage of the grain in the port, the bulk grain stored in the storage of the transfer grain needs to be added, and the formed transportation path searching model can be as follows:
traversing a bulk grain transportation directed graph, if the quantity of the required bulk grains stored in the transfer grain bin can meet the quantity of the required bulk grains stored in the port grain storage, finding a first transfer grain storage which has the shortest path with the port grain storage and stores the required bulk grains, circularly traversing the bulk grain transportation directed graph, if the quantity of the required bulk grains stored in the transfer grain storage can be found and the sum of the quantity of the required bulk grains stored in the first transfer grain storage meets the quantity of the required bulk grains stored in the port grain storage, finding a cooperation relation between the transfer grain storage and the first transfer grain storage, and generating a cooperation relation set, wherein the cooperation relation set is expressed as:

And (5) corresponding grain storage, and finally determining the actual shortest path.
The method comprises the steps of firstly determining a middle-transfer grain warehouse with the shortest path with the port grain warehouse, wherein the middle-transfer grain warehouse stores needed bulk grain, but the quantity is insufficient, adding the needed bulk grain with the bulk grain in other middle-transfer grain warehouses to meet the quantity of the bulk grain needed by the port grain warehouse, finding a model through the transportation path to know that one middle-transfer grain warehouse can meet the quantity of the bulk grain needed, or other combination forms can meet the quantity of the bulk grain needed, and comparing the combination forms.
The invention not only considers the aspect of bulk grain transportation, but also considers how to improve efficiency from grain loading and unloading processes, because the prior art usually realizes the loading and unloading operation of the grain raw material bin by manpower, the links of arranging operation, commanding operation, supervising operation, recording operation and the like are all dependent on manpower, therefore, in the process of executing the loading and unloading operation of the grain raw material bin, the problems of unordered operation, easy error, human cheating, supervision inadequacy, low efficiency and the like exist, the invention simultaneously brings the scheme of automatic adjustment of loading and unloading equipment into the whole technical scheme of the invention, and the scheme is matched with the above transportation technical scheme, optimizes the prior art at the transportation end and the loading and unloading end, thereby achieving the technical effect of improving efficiency in the whole flow of the water path transportation of grains, and is as follows:
further, the operating time of the loading and unloading equipment is optimized when the needed bulk grain is loaded and unloaded.
Specifically, the optimizing the operation time of the loading and unloading equipment comprises: assuming that the required bulk grain transportation flow totally passes through N loading and unloading devices, the loading and unloading devices are sequentially arranged

After the required bulk grain quantity is sent to the next transit grain storage, continuing to traverse until the required bulk grain quantity is sent to the port grain storage. For example, when bulk grain is transported from a storage of intermediate grain, not only the length of the path but also the data of the grain in the storage of intermediate grain are considered, if a certain data is out of specification, for example, the temperature exceeds the highest temperature that the grain can storeIf the temperature is not timely transported, the grains are likely to be putrefactive, so that the aim of selecting the grain storage can be better achieved by integrating indexes of grains and transportation paths of the grain storage, and when bulk grains are transported from one grain storage to the next grain storage, the bulk grains are traversed, because the time is needed for transporting the bulk grains from one grain storage to the next grain storage, in the time, the storage parameters of the corresponding bulk grains of other grain storage are likely to be changed, even the storage parameters of the bulk grains cannot meet the corresponding storage standards, and then the bulk grains transported to the next grain storage are likely to meet the storage standards, so that the risk of grain putrefaction can be greatly reduced.
The above transportation path searching model is provided that the number of bulk grains stored in the bulk grain storage must be equal to the number of bulk grains required by the port grain storage in the transportation directed graph, because in the actual operation process, the bulk grains stored in the vicinity of the port grain storage are generally equal to the bulk grains required by the port transportation, but one case is that the vicinity of the port grain storage is equal to the bulk grains required by the port transportation, and as shown above, the other case is that the vicinity of the port is equal to the bulk grains required by the port grain storage, and the bulk grains stored in the vicinity of the port are not equal to the bulk grains required by the port grain storage, so that the addition of the bulk grains stored in the vicinity of the port is required to meet the bulk grain required by the port storage, and the following steps are required:
specifically, when the bulk grain stored in the storage of the transfer grain near the port can meet the quantity of the bulk grain required by the storage of the grain in the port, the bulk grain stored in the storage of the transfer grain needs to be added, and the formed transportation path searching model can be as follows:
traversing a bulk grain transportation directed graph, if the quantity of the required bulk grains stored in the transfer grain bin can meet the quantity of the required bulk grains stored in the port grain storage, finding a first transfer grain storage which has the shortest path with the port grain storage and stores the required bulk grains, circularly traversing the bulk grain transportation directed graph, if the quantity of the required bulk grains stored in the transfer grain storage can be found and the sum of the quantity of the required bulk grains stored in the first transfer grain storage meets the quantity of the required bulk grains stored in the port grain storage, finding a cooperation relation between the transfer grain storage and the first transfer grain storage, and generating a cooperation relation set, wherein the cooperation relation set is expressed as:

The method comprises the steps of firstly determining a middle-transfer grain warehouse with the shortest path with the port grain warehouse, wherein the middle-transfer grain warehouse stores needed bulk grain, but the quantity is insufficient, adding the needed bulk grain with the bulk grain in other middle-transfer grain warehouses to meet the quantity of the bulk grain needed by the port grain warehouse, finding a model through the transportation path to know that one middle-transfer grain warehouse can meet the quantity of the bulk grain needed, or other combination forms can meet the quantity of the bulk grain needed, and comparing the combination forms.
The invention not only considers the aspect of bulk grain transportation, but also considers how to improve efficiency from grain loading and unloading processes, because the prior art usually realizes the loading and unloading operation of the grain raw material bin by manpower, the links of arranging operation, commanding operation, supervising operation, recording operation and the like are all dependent on manpower, therefore, in the process of executing the loading and unloading operation of the grain raw material bin, the problems of unordered operation, easy error, human cheating, supervision inadequacy, low efficiency and the like exist, the invention simultaneously brings the scheme of automatic adjustment of loading and unloading equipment into the whole technical scheme of the invention, and the scheme is matched with the above transportation technical scheme, optimizes the prior art at the transportation end and the loading and unloading end, thereby achieving the technical effect of improving efficiency in the whole flow of the water path transportation of grains, and is as follows:
further, the operating time of the loading and unloading equipment is optimized when the needed bulk grain is loaded and unloaded.
Specifically, the optimizing the operation time of the loading and unloading equipment comprises: assuming that the required bulk grain transportation flow totally passes through N loading and unloading devices, the loading and unloading devices are sequentially arranged

After the required bulk grain quantity is sent to the next transit grain storage, continuing to traverse until the required bulk grain quantity is sent to the port grain storage. For example, when bulk grain required for transporting from a middle grain warehouse is not only considered, but also considered, if a certain item of data exceeds a standard, for example, the temperature exceeds the highest temperature that grains can be stored, the grains may be spoiled, if the bulk grain is not transported timely, so that the purpose of selecting the middle grain warehouse can be better achieved by integrating indexes of the grains and transport paths of the middle grain warehouse, and when bulk grain is transported from one middle grain warehouse to the next middle grain warehouse, the bulk grain needs to be traversed, because the bulk grain needs to be transported from one middle grain warehouse to the next middle grain warehouse, during the time, the storage parameters of the corresponding bulk grain in other middle grain warehouses are likely to change, even the corresponding storage standard is not met, at this time, the bulk grain transported to the next middle grain warehouse may be required to continue to traverse, and the risk of spoiling the bulk grain generated by transporting from the middle grain warehouse which does not meet the storage standard can be greatly reduced.
