Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle allocation simulation system for simulating the vehicle layout of an agitator vehicle for transporting ready-mixed concrete in a ready-mixed concrete manufacturing plant.

[0002]

2. Description of the Related Art In a ready-mixed concrete manufacturing plant, ready-mixed concrete is appropriately manufactured in response to shipping requests from a plurality of shipping destinations according to the shipping amount and delivery time of each shipping destination. A suitable number of agitator vehicles for transporting fresh concrete are arranged, and the produced fresh concrete is loaded on each of the agitator vehicles and shipped to each shipping destination. Here, the vehicle allocation of the agitator vehicle is performed based on the vehicle allocation plan created in advance so as to comply with various conditions such as the number of shipping destinations, the shipping amount, and the carry-in time. This vehicle allocation plan is created. The work is not easy at all, and the veteran dispatcher spends a lot of time every day relying on his years of experience and intuition.

[0003]

However, in the conventional method of creating a vehicle dispatch plan as described above, the vehicle dispatch plan is created only by a very limited number of experienced vehicle dispatchers because it depends largely on the experience of the vehicle dispatcher. It was not possible to do so, and the burden on such a dispatcher was heavy. Also, when creating a vehicle allocation plan, it is difficult to deal with situations where there are not enough agitator vehicles at the time of actual shipping, so even if you are a veteran vehicle dispatcher, you will definitely have a generous vehicle allocation plan. This tends to increase transportation costs.

In view of the above points, it is an object of the present invention to provide a vehicle allocation simulation system for an agitator vehicle to assist in easily creating an appropriate vehicle allocation plan even if not a seasoned vehicle dispatcher.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a vehicle allocation simulation system for an agitator vehicle according to claim 1, in which an agitator vehicle for transporting ready-mixed concrete in a ready-mixed concrete manufacturing plant is used.

The third step of automatically reading out the required casting time from the actual data, and Computer is characterized by consisting of a fourth step of dispatching simulation of the agitator wheel based on various data obtained at each step.

Further, the vehicle allocation simulation system for an agitator vehicle according to a second aspect is characterized in that in the vehicle allocation simulation, at least the required number of agitator vehicles is derived on an hourly basis.

Further, in the vehicle allocation simulation system for an agitator vehicle according to claim 3, the agitator vehicle is equipped with a GPS for operation management, and the agitator vehicle is based on the operation information from the GPS and the plant and its shipping destination. The feature is that the actual travel time required to move between the locations and the actual pouring time required for pouring ready-mixed concrete at the shipping destination are aggregated and stored as actual data in the computer. I am trying.

[0008]

According to the vehicle allocation simulation system for an agitator vehicle according to claim 1 of the present invention, a vehicle allocation simulation computer installed on the plant side is provided with at least a capacity of ready concrete production per unit time of the plant. Enter in advance. Then, in response to the shipping request from each shipping destination, the dispatcher inputs at least the shipping amount to each shipping destination, the carry-in time, etc. into the computer. Here, on the basis of the past shipment record, the computer, for each shipping destination, the moving time required for the agitator vehicle to move from the plant to the shipping destination, the pouring time required for pouring ready-mixed concrete at the shipping destination, etc. The aggregated data is stored as actual data, and the actual data according to the input shipping destination is automatically read.

When the shipping schedule for one day has been entered into the computer, the computer will simulate the dispatch of the agitator vehicle based on these various data. The results of this simulation are graphed in various forms and output to a monitor or printer, and the dispatcher creates an optimal dispatch plan by referring to them.

As described above, the vehicle dispatcher only needs to input the order data into the computer in response to the shipping request, and the computer automatically reads the past performance data of the shipping destination, and performs the vehicle dispatch simulation based on these various data. Since this is performed, even if the dispatcher who has little experience is able to easily and quickly create an appropriate dispatch plan while observing this simulation result.

Further, according to the vehicle allocation simulation system for an agitator vehicle according to the second aspect, as a result of the simulation, the required number of agitator vehicles required for shipping at least one day is derived on an hourly basis.
By looking at this result, the dispatcher can easily and surely know how many agitator cars are needed between what time, and based on this, a dispatch plan can be created and the agitator owned by the company Compared with the number of cars, it is possible to make a request for a hired car without waste in time units.

According to the vehicle allocation simulation system for an agitator vehicle according to the third aspect of the invention, the travel time actually required for the agitator vehicle to travel from the plant to the shipping destination is determined from the operation information from the GPS provided in the agitator vehicle. And the actual casting time required for pouring ready-mixed concrete is automatically stored in the computer as the actual result data, so that the actual result data can be obtained easily and surely and based on this. Therefore, the simulation for the subsequent shipment can be performed accurately.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a flow chart showing a procedure for executing a vehicle allocation simulation system for an agitator vehicle according to the present invention. A computer installed in a vehicle allocation center on the plant side preliminarily manufactures ready-mixed concrete per unit time of the plant. The ability, for example, how many cubic meters of ready-mixed concrete can be produced in one hour is input (S1).

Then, upon receiving a request for shipment of ready-mixed concrete from each shipping destination such as a construction site, the dispatcher inputs into the computer the order data such as the shipping amount and the delivery time for the shipping destination (S2). After finishing the input of the order data, it is confirmed whether or not there is order data from another shipping destination (S
3) If there is, return to S2 to continue inputting order data,
If not, proceed to S4.

Upon completion of inputting all order data, the computer automatically confirms whether or not there is a shipment record for each input shipment destination (S4), and if there is a record, the agitator vehicle moves between the plant and the shipment destination. While reading the actual data such as the moving time required to do it and the pouring time required for pouring ready-mixed concrete at each shipping destination (S5), the dispatcher will only work if it is a new property and has no shipping record. The moving time of the agitator vehicle and the placing time at the shipping destination are roughly predicted and the temporary record data is input (S6).

Then, based on the various data obtained in S1, S2, S5 and S6, the dispatch of the agitator vehicle is simulated by a computer (S7), and the results of this simulation are graphed in various forms and displayed on a monitor or a printer. (S8), and the dispatcher creates a dispatch plan with reference to this result (S9).

On the other hand, when the ready-mixed concrete is shipped to each shipping destination in accordance with the vehicle allocation plan thus created, the vehicle allocation center monitors the operation of each agitator vehicle by the GPS provided in each agitator vehicle (S10), and the plant and each plant. The travel time actually required for the agitator vehicle to move between the shipping destinations and the pouring time actually required for pouring the ready-mixed concrete at each shipping destination are automatically aggregated as actual data (S
11). The result data thus aggregated is stored in the computer (S12), and is read out at the time of next shipment and used for simulation.

Here, the contents of the simulation will be described in detail. The computer subtracts the moving time required for the agitator vehicle to reach each shipping destination from the delivery time of each shipping destination, and the shipment from the plant for each shipping destination. Specify the time. In addition, the manufacturing time required to manufacture the ready-mixed concrete for each shipping destination in the plant is calculated from the plant capacity input in advance, and the manufacturing start time is specified so that it can be shipped at the shipping time specified above. .

Then, in the plant, at the start time of each production, ready-mixed concrete is produced in an amount corresponding to each shipping destination,
The ready-mixed concrete produced is sequentially delivered to one or more agitator cars at each shipping time, and these agitator cars move to each shipping destination over a predetermined traveling time, and each shipping destination takes a predetermined placing time. We will simulate a series of manufacturing and shipping work by placing fresh concrete, returning each agitator car that has become empty to the plant after a predetermined moving time, cleaning processing and preparing for the next shipment on an hourly basis. .

Based on the above simulation, the production schedule of ready-mixed concrete in the plant, the shipping schedule for each shipping destination, the operation schedule of each agitator vehicle, etc. are derived, together with the required number of agitator vehicles per hour. The graphs are output as shown in FIGS. 2 to 5 and output to a monitor or a printer. Then, the dispatcher creates an optimal dispatch plan with reference to these graphs.

At this time, if there is a time zone when the number of agitator vehicles owned by the plant cannot meet the shipping schedule, it can be easily confirmed from the graph of FIG. Immediately make appropriate adjustments such as advancing the delivery time to some shipping destinations within the allowable range, appropriately distribute the shipping times, and then simulate again. The result is immediately output to the graph, and if the shortage has been resolved, the dispatcher will make a dispatch plan while referring to the graph at that time, while if the agitator vehicle runs short, Request a car with a shortage of agitator units per unit.

As described above, in the past, if the agitation vehicle was running short in the shipping schedule, the hiring request was made and the vehicle allocation plan was created accordingly.
According to the present invention, it is possible to easily change even after the shipping schedule has been issued once, and the changed schedule can be immediately confirmed in the graph, so that the shipping schedule can be adjusted many times and a detailed shipping schedule can be set. It is possible to create a vehicle allocation plan by making a lean request for a hired car.

If the production schedule of the ready-mixed concrete of the plant exceeds the production capacity of the plant per unit time, it can be easily confirmed from the graph of FIG. 3 to prevent an unreasonable order and prevent an appropriate order. It can be carried out.

Further, since the operation schedule of each agitator vehicle is clarified from the graph of FIG. 5, it is easy to prioritize the operation of the company's own agitator vehicle, and it is possible to reduce the cost. It is possible to accurately grasp the vacant time and, for example, by accepting orders for spot shipments according to the time zone, it is possible to expand new business opportunities.

As described above, if the dispatcher inputs only the order data to the computer in response to the shipping request, the computer automatically performs the dispatch simulation based on the various data, and graphs the simulation result in various forms. Since it is output, even if a dispatcher with little experience can quickly respond to various requests and refer to these graphs, an appropriate dispatch plan can be created easily and quickly. is there.

Further, since the operation information from the GPS provided in the agitator vehicle is automatically stored in the computer as the performance data, the performance data can be obtained easily and surely, and thereafter, based on this, It is possible to accurately perform the simulation for the shipment of. Furthermore,
Even if the actual result data already exists, it is preferable to update the actual result data every time because accurate simulation can always be performed.

In this embodiment, the raw concrete production capacity per unit time of the plant is given as the data to be inputted to the computer in advance, but other than this, for example, the maximum load amount of each agitator vehicle may be inputted. If the lever data is also added to the simulation,
It is possible to create a vehicle allocation plan that is more efficient in transportation.
