Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, in one embodiment, it is provided that a kind of MRP calculates course control method for use, and the method includes:
Step S110, obtains demand bills data.
Demand document refers to the document representing material requirement. Just generate before the calculating that demand document is typically in MRP, such as product prediction list, sales order, export trade order etc. Carry out the calculating of MRP, must first obtain demand bills data.
Step S120, is sequentially carried out material net demand calculating, material substitution calculating and estimate simulation according to described demand bills data and calculates
In circulation enterprise, various demands are often independent. And in production system, demand has dependency. Such as, after order determines the quantity of required product according to demand, can being extrapolated various parts and raw-material quantity by new product structured file BOM (BillofMaterial, BOM), this material quantity calculating out according to logical relation is called related needs. Not only kind quantity has dependency, and required time is also relevant to the decision of production process.
Being typically based on the obtained demand of demand bills data is quantity gross, but because the existence of available stock amount, Allocation so that net demand amount and quantity gross are also inconsistent, so needing to carry out material net demand calculating.
It addition, when carrying out MRP and calculating, if during the available stock deficiency of subitem material, for reducing production cost, generally require and the material unclassified stores lacked substituted. Therefore, in the system of MRP is arranged, generally all can to the substitutional relation of material time row arrange so that the material substitution in later stage calculates.
The last estimate that carries out again simulates calculating.
Step S130, generates planned order according to the result that the simulation of described estimate calculates.
Generating planned order is the MRP final purpose calculated. Whole MRP calculate excessively in; system generally has the document newly increased; if and MRP calculates process and is controlled by the source code of system completely; calculating process cannot include the document newly increased in calculating; the data message that so may result in planned order there are differences with the data message being actually needed; and this species diversity constantly can expand along with the operation of system, brings loss to enterprise.
In the present embodiment, triggering event is both defined before step S110, step S120 and step S130. Such user can insert self defining programm very neatly in each triggering event, to realize self-defined control MRP calculating process.
Further, in other embodiments, this MRP calculates course control method for use and also includes the step of way of compiling control plug-in unit and activate described triggering event to call the step of described control plug-in unit, and it calls schematic diagram as shown in Figure 2.
Specifically, the step of described way of compiling control plug-in unit includes:
Create MRP and calculate the interim table of physics of process;
The document newly increased is joined the interim table of described physics.
The document newly increased is joined in the interim table of described physics, be mainly easy to follow-up calculating. Wherein, the document newly increased described in is one or more in production job order, procurement request list, purchase order, sales order and product prediction list.
In one embodiment, the data that the step of described way of compiling control plug-in unit also includes revising in the interim table of described physics calculate to adjust MRP.
As it is shown on figure 3, in one embodiment, it is provided that a kind of MRP calculates the system of process control, including:
Acquisition module 210, is used for obtaining demand bills data.
Computing module 220, for being sequentially carried out according to described demand bills data, material net demand calculates, material substitution calculates and estimate simulation calculates.
Order generation module 230, order generation module, generate planned order for the result calculated according to the simulation of described estimate.
Wherein, at least one module above-mentioned both defines triggering event, specifically as shown in Figure 3.
Being appreciated that in other embodiments, this MRP calculates Process Control System and also includes:
Collector, for way of compiling control plug-in unit;
Activation calls module, is used for activating described triggering event to call described control plug-in unit.
Wherein, described collector include for create MRP calculate process the interim table of physics creating unit, for the document newly increased being joined the adding device of the interim table of described physics and the data that are used for revising in the interim table of described physics to adjust the amendment unit of MRP calculating.
In one embodiment, the document newly increased described in is one or more in production job order, procurement request list, purchase order, sales order and product prediction list.
Above-mentioned MRP calculates course control method for use and system by defining triggering event before at least one step, make user can insert self defining programm very neatly in each triggering event, such as control plug-in unit, so facilitate user to realize self-defined control MRP and calculate process.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.
