Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.

In a first aspect, an embodiment of the present invention provides a method of production planning.

Referring to fig. 1, the method includes the following steps S110 to S150:

s110, determining a first production order which can be completed in a future first planning period in a task pool according to production constraint conditions;

wherein the first planning period, for example, one month, one quarter, etc.

It will be appreciated that the production orders in the task pool are all unordered task orders, and that their production plans need to be arranged and placed.

Wherein, the production constraint conditions can comprise: factory capacity information, information of production orders that have been placed to production departments, resource readiness, etc. The capacity information of the factory refers to the production capacity of the factory, and generally, the larger the number of production lines is, the higher the capacity is; the higher the utilization of the production line, the higher the productivity. The information of the production order which has been issued to the production department includes the number of products, the kinds of products, etc. in the order which has been issued to the production department and is waiting for the production department to perform the production activity, which requires the time and resources of the production line to be occupied, etc. The resource preparation conditions comprise production line technology preparation conditions, material preparation conditions and the like. The technical preparation condition refers to whether technicians, equipment of a production line are ready or not, and the material preparation condition refers to whether materials required for producing products are ready or not.

In one embodiment, S110 may include the following steps S111 to S113:

s111, determining production time length and required resources required by each production order in the task pool;

s112, judging whether each production order in the task pool can be completed in the first planning period according to production constraint conditions, production duration required by each production order in the task pool and required resources;

s113, if yes, taking each production order in the task pool as the first production order;

wherein the production constraints include at least one of capacity information of the plant, information of a production order that has been placed to a production department, and resource preparation conditions including production line technology preparation conditions and/or material preparation conditions.

That is, first, the production time and the resources required for each production order in the task pool are determined, and the production time and the resources required for each production order in the production pool are respectively summarized. And then judging whether the allocable production duration of the factory in the first planning period can cover the summarized production duration according to various production constraint conditions, and judging whether the allocable resource of the factory in the first planning period can cover the summarized resource. The allocable production duration needs to consider the total production duration in the first planning period and the production duration required by the production order issued to the production department. The above-mentioned allocable resources need to take into account resources that are available in the first planning period, resources that are required for the production order that has been placed to the production department. If the allocable production duration can cover the summarized production duration and the allocable resources of the factory in the first planning period can cover the summarized resources, the method indicates that the production orders in the task pool can be completed in the first planning period, otherwise, the production orders in the task pool cannot be completed. If each production order in the task pool is capable of being completed within the first planning period, each production order in the task pool is taken as a first production order.

It can be seen that in determining whether each production order in the task pool can be completed within the first planning period, production constraints are taken into account, which are each factors that have an influence on production in the actual production process. In this way, it can be accurately determined whether each production order in the task pool can be completed within the first planning period.

Wherein the production constraint condition comprises at least one of capacity information of a factory, information of a production order issued to a production department and resource preparation conditions, and the resource preparation conditions comprise production line technology preparation conditions and/or material preparation conditions. The productivity information of the factory represents the enterprise production capacity of the factory, the resource preparation condition represents the internal and external resource constraint condition of the factory, and the information of the production order issued to the production department can represent the current workload of the factory, so that the first production order is determined based on the information, the actual scene is met, and the accuracy is high.

Further, the step S110 may further include the following steps:

if each production order in the task pool cannot be completed in the first planning period, determining whether overtime can be scheduled according to the current production calendar of the factory;

If overtime cannot be scheduled or each production order in the task pool cannot be completed in the first planning period after overtime is scheduled, screening from each production order in the task pool according to the attribute information of the production order, and taking the screened production order as a first production order; wherein the attribute information comprises the delivery date of the production order and/or the customer importance degree corresponding to the production order;

if overtime can be scheduled, and each production order in the task pool can be completed in the first planning period after overtime is scheduled, taking each production order in the task pool as the first production order, and updating the current production calendar.

That is, based on the current production calendar, if each production order in the task pool cannot be completed within the first planning period, it may be determined whether overtime can be scheduled according to the current production calendar. The production calendar is information such as which day the production activity is performed, which day the production calendar is put on, and the working time of the production day. For example, the current production calendar performs production activities for monday to friday of one week, holidays for friday, and the working time period for monday to friday is 8 from morning: 00 to 8: the working time period from the fourth day to the friday is 8 in the morning: 00 to 6 pm: 00, it is thus possible to arrange for the duration of the production campaign to be prolonged on tuesday, friday, or even for the production campaign to be scheduled on friday. And by the overtime mode, the working time of the production line is prolonged, and the working yield in the first planning period is further improved.

If each production order in the task pool is still unable to complete within the first planning period after the overtime is scheduled, or it is determined that the overtime cannot be scheduled any more based on the current production calendar, only a portion of the production orders from the task pool can be screened to complete within the first planning period, and the remaining production orders can complete within the next first planning period. The screened production order is used as a first production order of a first planning period.

When screening the first production order, the screening can be performed according to attribute information of the production order, wherein the attribute information comprises delivery date, customer importance degree and the like of the production order. For example, if a production order with a closer delivery date and a more important customer is selected as the first production order, a production order with a more distant delivery date from the current date or a less important customer may be placed in the next first planning period for execution.

Of course, if overtime can be scheduled and each production order in the task pool can be completed within the first planning period after overtime is scheduled, each production order in the task pool can be taken as the first production order. Updates to the production calendar are required if overtime can be scheduled.

It will be appreciated that, after the first production orders that can be executed in the first planning period, the first production orders need materials of which kind, the amount of materials needed, the production calendar of the factory, the productivity of each day in the first planning period, etc. can be determined by S110.

It is understood that S110 is actually a large schedule capacity assessment activity.

In one embodiment, prior to S110, the method may further include:

s100, generating a corresponding production order according to a sales order submitted by a sales department, and importing the production order into the task pool; the production order comprises delivery period, specification and quantity of products, importance degree of clients and whether personalized requirements exist.

That is, the sales department, after submitting the sales order, may generate a corresponding production order from the sales order. Specifically, a plurality of items of information of a sales order are input into a computing device, after the input is completed, the information generates a production order, and then the production order is imported into a task pool. The sales order may be an order for which a contract has been completed, or an intentional order received at a sales site.

The production order may include a plurality of items of information such as delivery date, specifications of the product and the number of each specification, customer importance, whether there is a personalized demand, etc. Individualization requirements, e.g., whether a particular component is specified, whether customer confirmation of the final solution is required, etc.

S120, determining a main production plan corresponding to each first production order, and splitting each main production plan into a plurality of work orders;

that is, a corresponding primary production plan is determined for each production order, and then the primary production plan is split to obtain a plurality of work orders, one work order corresponding to each production activity, for example, one work order being a work order assembled to form a handlebar, and one work order being a work order assembled to form a pedal.

Where work orders refer to the smallest planned unit of tissue production.

In one embodiment, determining the primary production plan for each first production order in S120 may include: and determining the specification of the product to be produced and the number of products corresponding to each specification according to each first production order, and obtaining the main production plan.

It can be seen that the main production plan can include what specifications of product are to be produced and how much of each specification of product needs to be produced. That is, a corresponding master production plan may be extracted from one of the first production orders.

In one embodiment, splitting each primary production plan into a plurality of work orders as described in S120 may include: splitting the main production plan corresponding to each first production order into a plurality of work orders according to the production strategy and the process line of the product corresponding to the first production order; the process line comprises whether self-made parts and manufacturing process information are needed or not;

wherein the self-made production work order is a production work order of parts to be self-made in the product; the part production work order is a production work order in which a plurality of parts are assembled into one component part of the product; the assembly production work order is a production work order for assembling each component part into the product; the zero production work order is a work order of production activities except homemade parts, assembling a plurality of parts into one component part and assembling a plurality of component parts into a product in the production process of the product; the assembly production worksheets, the part assembly production worksheets corresponding to the component parts of the product and the homemade production worksheets corresponding to homemade parts in all parts required by each part assembly production worksheet are in an assembly hierarchical relationship.

The production strategy refers to the sequence of all production activities in the production process of one product. For example, one product of a production order is a bicycle, and the production strategy may be: purchasing other parts than the tire; the factory produces the tire by itself, then assemble the wheel; assembling a handle; assembling a pedal; the individual components are assembled into a bicycle. The steps of assembling the wheels, assembling the handles, assembling the pedals, etc. may be performed simultaneously.

Wherein, the process line comprises self-made parts and manufacturing process information; that is, which part or parts of a product need to be self-made and which parts need to be purchased, e.g., for bicycles, the factory itself produces tires, and other parts need to be purchased. The manufacturing process information includes which stations and modes of operation are required for the production campaign. There are various working modes, for example, the work of one station is completed and then transferred to the next station, and each station works simultaneously, etc. For example, during the production of a bicycle, some steps may be performed simultaneously, with some steps being in sequence.

That is, the primary production plan for a first production order may be split into work orders according to the production strategy and process lines for the product for that first production order. The kinds of work orders include a plurality of kinds, for example, a homemade production work order, a part production work order, a general assembly production work order, and a zero-order production work order. Wherein a self-made production work order is a production work order of parts in the product that need to be self-made, for example, a work order of producing tires. The assembly production worksheet is a production worksheet in which a plurality of parts are assembled into one component of the product, for example, a worksheet in which a handle of a vehicle is assembled, a worksheet in which a foot pedal is assembled, a worksheet in which wheels are assembled, and the like. The assembly production worksheet is a production worksheet for assembling each component part into the product, for example, a complete bicycle worksheet for assembling a handlebar, wheels and pedals. The production work order is a work order of production activities except homemade parts, assembling a plurality of parts into one component part and combining a plurality of component parts into a product in the production process of the product. For example, a work order for inflating a produced tire, such as inflating a tire, may be completed within a certain period of time within a first planning period, e.g., focusing on a certain day or days for inflating all tires.

It can be seen that, for a main production plan, multiple worksheets can be obtained through splitting, and each worksheet has a certain hierarchical relationship, for example, a hierarchical relationship is formed between a final assembly production worksheet, a part assembly production worksheet corresponding to each component part, and a homemade production worksheet of homemade parts in each part required in one component part, and the hierarchical relationship is called an assembly hierarchical relationship.

S130, designating the time of the online and the offline and the allocation of resources on a production line for each work order according to the association constraint condition among a plurality of work orders corresponding to each first production order, wherein the time of the online and the offline is in the first planning period;

it can be understood that, it is known from S120 that some worksheets have assembly hierarchical relationships, and these assembly hierarchical relationships may form association constraint conditions, and according to the association constraint conditions, an online time and an offline time may be allocated to each worksheet, and a resource may be allocated to each worksheet. Resources include both technical resources and material resources.

The time of the work order on line and off line refers to the time point when the required work station starts to execute the production activity corresponding to the work order and the time point when the required work station ends to execute the production activity. If a work order requires multiple stations and a work production activity is completed and then a next station is required, only the first station may be designated for offline time. Wherein, the resource allocation refers to the allocation of resources, such as material resources and technician resources, for each station of a work order.

In one embodiment, the association constraint includes a hierarchical relationship of assembly between worksheets; correspondingly, the S130 may include:

s131, according to the assembly hierarchical relation among the work orders, specifying the time of the work orders on line and off line on the production line and distributing resources for each work order so as to realize the scheduling of the work orders; the latest processing completion time of the self-made production work order of one self-made part or the purchasing and warehousing time of one purchased part is earlier than the starting processing time of the part production work order corresponding to the component part to which the part belongs, and the latest processing completion time of each part production work order is earlier than the starting processing time of the assembly production work order.

That is, when specifying the time of the on-line and off-line for each work order, it is necessary to consider the assembly hierarchy relationship between the respective work orders. Specifically, the latest processing completion time of the self-made production work order of a self-made part needs to be the processing starting time of the part production work order corresponding to the component part to which the self-made part belongs, and the purchasing and warehousing time of a purchased part is earlier than the processing starting time of the part production work order corresponding to the component part to which the purchased part belongs. That is, only after the production of the self-made parts and the purchase of the purchased parts, the assembly work of the corresponding components can be performed. The latest processing time of each assembly production work order is earlier than the starting processing time of the assembly production work order, that is, each assembly part can be assembled into a complete product after the assembly of each assembly part is completed.

Therefore, through the constraint of the assembly hierarchical relation, the appointed time of the online and the offline accords with the production strategy and the process line of a product, namely, the appointed time of the online and the offline accords with the actual production scene of the product, so that the executable of each work order of the product is greatly improved.

Further, S131 may specifically include: and designating the on-line and off-line time and the allocated resources on the production line for each work order according to the assembly hierarchy relation among the work orders, the resource preparation condition, the current production calendar and the working hours required by each work order.

That is, when specifying the time of the line up and down, not only the assembly hierarchy relationship but also the resource preparation condition needs to be considered, for example, some materials or some technicians need to be prepared to be completed on a certain date, and therefore the time of the line up and down specified for the work order requiring the materials or the technicians needs to be after the date and the date. There is also a need to consider the current production calendar, e.g. which day to produce, which day to leave on, working time period of the production day. The on-line and off-line times need to be scheduled to be valid during the working hours of the production day. It is also necessary to consider the man-hours required for each work order, and only after the production activity of one work order at one station is completed, the next work order can be arranged to carry out the production activity at the station. Of course, it is also necessary to consider that the scheduling of the work orders that have been issued at present, i.e., the time of the on-line and off-line of the work orders that have not been issued to the production department at present, in the first planning period, cannot affect the normal execution of the work orders that have been issued to the production department.

S140, selecting at least one work order from each work order of each first production order according to a business requirement rule, locking the selected work order, wherein the locked work order occupies the corresponding online time and the corresponding resource;

it can be appreciated that the business requirement rules are different in different application scenarios, and thus the manner in which at least one work order is selected from among the work orders is different.

In one embodiment, S140 may specifically include at least one of:

(1) If the business requirement rule is that the order is placed according to the production calendar, selecting each work order executed in a future second planning period from each work order of each first production order according to the time of the online and offline of each work order of each first production order; wherein the second scheduled period is one time unit which is closest to the current date in the production calendar, and the time length of the second scheduled period is smaller than that of the first scheduled period;

(2) If the business requirement rule is that the order is placed according to the production orders, selecting each work order of at least one first production order from each work order of each first production order according to the customer importance degree of each first production order;

(3) And if the business requirement rule is that the order is placed according to the insertion order, taking each work order of the temporarily inserted production order as the selected work order.

Wherein in (1), the time length of the second scheduled period is smaller than the time length of the first scheduled period, and the second scheduled period is one time unit closest to the current date in the production calendar. For example, the first planning period is one month, the second planning period is 5 days, the current date is friday, and the current production calendar is not overtime on Saturday, and the second planning period is Monday to friday of the next week. Therefore, each work order with the time of getting on and off line from the next week to the next friday is screened from each work order of each first production order, and each selected work order is locked, so that the work order can be ordered. This is the way the order is made in accordance with the production calendar.

In (2), if the importance of the customer of a certain or some first production orders is very high, the factory will very pay attention to the customer of the first production order, so that each work order of the first production order is selected from the work orders of each first production order, and the selected work order is placed. For example, if the importance of the factory to the first production orders of the customer a and the customer b is high, the work orders of the first production orders of the customer a and the work orders of the first production orders of the customer b are screened out from all the work orders of the first production orders, the work orders of the first production orders of the customer a and the work orders of the first production orders of the customer b are locked, and then the order is placed, the work orders of the two customers are not affected by other work orders, and the production demands of the two customers are preferentially ensured.

In (3), if one or more production orders are inserted into each current first production order, the business requirement rule indicates that the temporarily inserted production order needs emergency treatment, and the business requirement rule is to place the order according to the insertion order, so that each work order of the temporarily inserted production order is firstly locked and placed, and each work order of each current first production order is considered to deal with emergency treatment.

Therefore, when locking order, a plurality of processing modes exist, and different processing modes can be adopted according to different business requirement rules, so that the locking order process is very flexible, changes according to actual conditions, and meets the actual requirements of application scenes.

The locked work orders occupy a certain time and resources for getting on and off lines, so that the work orders which are locked subsequently can not be used for getting on and off lines, which are occupied by the work orders which are locked previously, any more, and therefore the locking can ensure that the time and the resources for getting on and off lines of the work orders are not occupied by the subsequent work orders.

And S150, issuing the locked worksheets to a production department, so that the production department performs production activities according to the received on-line and off-line time and the received resources corresponding to each worksheet.

That is, the locked work order is issued to the production department, so that the production department receives the work order and then performs production activities according to the time and resources of the work order, i.e., executes the work order.

In one embodiment, the method provided by the embodiment of the invention can further include:

if the work order which is locked but not executed is needed to be unlocked according to the actual production situation, the work order and each work order which has an assembly hierarchy relation with the work order are unlocked, the unlocked work order does not occupy the corresponding online time and the corresponding resource, and an unlocking instruction is issued to the production department.

In a practical scenario, for example, there are cases where a temporarily inserted work order needs emergency treatment, a work order that has been previously locked but has not yet been executed needs to be unlocked, and when unlocking, not only this work order but also each work order having an assembly hierarchical relationship with the work order needs to be unlocked, because state consistency between each work order having an assembly relationship is to be maintained. The work order after being unlocked does not occupy corresponding online and offline time and resources. And issuing an unlocking instruction to the production department, wherein each work order which does not need to be unlocked after the production department receives the unlocking instruction is equivalent to the work order being withdrawn. If a work order was previously locked and has been executed, the work order cannot be unlocked.

It can be seen that the unlocked worksheet is a worksheet that has been locked but has not yet been executed, so that the production process of the production department is not disturbed, and timely and flexible handling is also possible when an emergency situation is encountered.

In summary, in the method provided by the embodiment of the invention, first production orders which can be completed in a future first planning period in a task pool are determined according to production constraint conditions, then main production plans corresponding to each first production order are determined, each main production plan is split into a plurality of work orders, further, the time for getting on/off line is designated for each work order and resources are allocated for each work order, at least one work order is selected according to business requirement rules, and the selected work order is locked, so that the locked work order occupies the corresponding time for getting on/off line and the resources, the production activity time and the production activity required resources of the locked work order can be ensured, and finally the locked work order is issued to a production department for production activity, and the work order is completed. It can be seen that in the above process, the production order that can be completed in the first planning period is selected as the first production order in consideration of the production constraint condition first, so that the first production order that can be completed in the first planning period can be obtained. And the main production plan corresponding to one first production order is split into a plurality of work orders, so that the production activity of the first production order can be refined, the production departments can directly produce according to the work orders, a large amount of coordination and scheduling work is not needed, and the executable performance can be improved. Moreover, when the time of the online and the time of the offline are specified and the resources are allocated, the association constraint conditions among the worksheets need to be considered, so that the time of the online and the time of the offline are specified and the resources are allocated to meet the association constraint conditions among the worksheets, and the executable performance of the worksheets is further improved. The method can solve the problems of accumulation of work in process, slow planning response and the like of the prior workshops due to the improvement of the executable performance.

Therefore, the embodiment of the invention can solve the problem of scheduling the production plan facing to the personalized customization demand, and solves the technical problems of reasonable production plan and fine distribution of production tasks of manufacturing enterprises with the personalized demand of customers in a multi-variety small-batch order production mode. In addition, elements such as order information, enterprise production capacity, internal and external production constraints and the like can be comprehensively considered, so that the production schedule is more balanced, more reasonable, more flexible and more executable. Meanwhile, time and cost are saved, and resource waste is reduced.

In a second aspect, an embodiment of the present invention provides a production scheduling apparatus, referring to fig. 2, the apparatus 100 includes:
