Therefore, compared with the mode that the conventional MRP mode is adopted by the ERP manufacturer to produce and manufacture products in a unified manner, the invention combines project management and product manufacture to form a brand-new framework for product mixed production and manufacture aiming at project requirements, and organically combines project requirements, project tasks, conventional purchase orders and production work orders by using a PRP (project requirement plan) and MRP (material requirement plan) dual engine and project requirement socket interface, thereby realizing the product production and manufacture mode supporting project manufacture and product manufacture in a mixed manner, effectively supporting nonstandard order-level micro project ETO business with low cost, complex process and rapid delivery, and improving the production efficiency of project products.

Further, a preferred embodiment of the product mix manufacturing method of the project business of the present invention is proposed based on the first embodiment and/or the second embodiment of the product mix manufacturing method of the project business of the present invention described above.

Referring to the application flow shown in fig. 4, in the embodiment, the product hybrid manufacturing method of the project business of the present invention is executed according to the following steps:

step 0, data management (material, BOM classification)

The following data definitions and maintenance are made:

materials: the method comprises the steps of setting material attributes 1 (general parts and special parts which are effective in a PRP module) and material attributes 2 (purchasing parts and manufacturing parts), and generating four combinations of general purchasing parts, general manufacturing parts, special purchasing parts and special manufacturing parts. Wherein general parts are processed by a material demand plan (MRP) and special parts are processed by a project demand plan (PRP).

Parameterized materials, BOM: the material has only one material code, but the material has the material object changed according to the parameter requirement, the material attribute is defined as a special part, and the BOM of the parameterized material can be changed according to different parameters. Like connecting pieces with the same model but different lengths, buttons with the same model but different numbers, and the like.

Product BOM: the bill of materials, also called a product structure table, is globally common and is the basis for the decomposition of the material demand plan. Logic checks are required, and BOM sub-parts such as generic parts cannot exist for specialized parts.

Item BOM: the BOM is initially imported by the product BOM and the parameterized BOM, is private to the project, can be modified without influencing the global BOM, and can increase the non-material requirements of the project, such as design, transportation and the like, which are the basis of project requirement plan decomposition.

The process route is as follows: the technical file describing the operation sequence of material processing and part assembly is a sequence of a plurality of working procedures, and comprises a global product process route and a single project private project process route, wherein the project process route is generated by leading the product process route into a specific single project.

Project Work Breakdown Structure (WBS): the product quantity of the sale contract project, the multi-level project requirement plan and tasks (activities) decomposed according to the project BOM and the process route. Including two mainlines:

(1) project requirement level numbers (1, 1.1, 1.2, 1.1.1, 1.1.2, etc. requirement tree structures) are indexes of project visualization, and the system automatically generates and manages project requirements and tasks at all levels.

(2) The project low-order codes (task levels of 0 order, 1 order, 2 order and the like) are the structural level sequence of the project BOM, the top level is 0 order, and the top level is 1 order, 2 order and 3 order … … in sequence.

Step 1, product BOM, parameterization BOM initial import project BOM (creating project requirement standard)

When receiving a project order, importing the product BOM and the parameterized BOM into a generated project BOM according to the parameterized requirements of customers, and simultaneously importing a project process route which is used as a standard basis for project requirement decomposition.

The project BOM is a single project private multi-level BOM that can be modified without affecting the global BOM and can increase the non-material requirements of the project.

Step 2, project Requirement Planning (PRP) (decomposition of project requirement)

The items of the sales contract are transmitted to the PRP module for processing, each detail line of the sales contract looks at the same miniature item, and each detail line of the sales contract has an independent item number (line number code) and is decomposed based on zero stock. PRP is divided into two layers:

(1) project plan (see step 2.1 in FIG. 4): that is, the product delivery requirements of the detail lines of the sales contract are requirements of the project itself. Distributing the attributes of the special parts and the common parts of the order line materials, generating a project 0-order task from the requirement of the special parts of the project, and submitting the requirement of the project common parts to an MRP module for meeting;

(2) project demand planning (see step 2.2 in FIG. 4): also known as project Work Breakdown Structure (WBS), is the lower level requirement of project breakdown. And decomposing the 0-order task of the special part project generated by the project plan according to the project BOM and the process route, dividing the flow by the attributes of the special part and the general part of the material, generating the 1-order task of the decomposed special part project, and submitting the requirements of the general part project to the MRP module for meeting. And similarly, continuing to decompose the task of the 1 st order of the project, and sequentially decomposing layer by layer until no task can be decomposed.

If the project production task comprises a plurality of working procedures, each working procedure activity in the task is decomposed from the process route, and the working procedures are the implementation and cost carriers of the task. But only the task decomposes the lower-order project demand plan, the demand plan can be refined to the process activity level distribution demand, and the activities in the task do not participate in decomposition.

The project BOM and the process route are the source standards of a project Work Breakdown Structure (WBS), each project is private, the elements of the project BOM and the process route can be modified, the whole project requirement plan and the whole project task activities can be refreshed at any time, the project task number is unchanged, and the project requirement plan and the project task activities comprise the associated change quantity, the time, the attributes and even the material names. Of course, if the data management is unified, the product BOM and the process route can be modified and then imported and updated to the project BOM and the process route from the data management software.

Because the special-purpose piece generates the project task, resources are naturally distinguished and occupied by the project task, and the upper and lower tasks are independently delivered, the special-purpose piece does not need to be put in and out of a warehouse, and the special-purpose piece does not require materials to be strictly in a one-object-one-code mode.

Step 3, calculating the required gap of the universal parts of each project (the requirement of the universal parts to be met by MRP)

When all project plans and Project Requirement Plans (PRP) calculate demands, general-purpose parts, special-purpose part demands and corresponding project task information are gathered to 'project demand complete set and task progress analysis', and information transmission of the general-purpose part demands to the MRP module is carried out.

And (3) firstly, according to the priority order, the universal part requirement gaps of the project tasks are flushed by the inventory of the project resource virtual library, the universal part requirements of the project tasks which cannot be met by the inventory are transmitted to the MRP system in an independent requirement mode, a purchase order or a production work order is generated, and if no redundant material of the project requirements exists in the inventory, exception information is prompted and the redundant material is processed in time.

The above operations can be performed for many times when the project requirement is changed, the latest universal part requirement gap which can not be met by the 'project resource virtual library' is calculated, and the MRP module is ready to meet the gap.

Step 4, material demand planning (MRP) (demand correlation operation for general parts)

The MRP module predicts stock and the PRP module carries out material demand planning (MRP) operation through a universal part demand gap of 'project demand complete set and task progress analysis' operation to generate purchase orders and all-level production work orders of universal parts, and the purchase orders and all-level production work orders are merged into a library to serve as universal part resource supply to meet the requirement of the universal parts of a sale contract project.

It should be noted that the sales contract in PRP is different from the type of sales order in MRP, and the sales contract documents do not participate in the MRP calculation.

Step 5, project requirement complete set and task progress analysis (project requirement and supply balance)

Analyzing the satisfaction degree of the general parts and the special parts of the project requirements in the MRP and the project task progress, visually tracking the whole process of the project and timely adjusting the project arrangement.

After the universal parts are put in a warehouse by the MRP module, the universal parts are automatically triggered to be virtually transferred to a 'project resource virtual library' (the warehouse is set to not participate in MRP calculation) in real time according to a project requirement rule, the universal parts are occupied for project requirements, resource pre-distribution is carried out according to the priority of the project requirements, after optimization and adjustment, a standard material receiving sheet of project tasks is triggered, and delivery warehouses of the projects are uniformly set as 'project resource virtual libraries'.

If the enterprise applies a Warehouse Management System (WMS), a 'project resource virtual library' is not set at the level of the WMS in order to facilitate the management of the material batch information. After the general part warehouse delivers the material receiving list of the project task, the general part warehouse triggered by the WMS layer receives the material receiving and accounts deducting, and the 'project resource virtual library' receives the material receiving and accounts deducting are returned by the ERP layer.

And after the task of the special-purpose piece is completed, updating the complete state of the project requirements.

After the general and special parts of the project requirements are completely met and completed, the start time of the next task is refreshed, and the next task of the project is convenient to start.

After the project planning layer requirements, namely the product delivery requirements of the detailed lines of the sales contract, are all met, the sales contract can be scheduled for delivery.

The project requirement complete set and progress analysis can analyze the satisfying condition of a 'project resource virtual library', can also expand and analyze the on-the-way of a general part production work order and a purchase order, can complete project tasks in the future, and can simulate and analyze the future complete set condition.

Because the objects of project manufacturing management are interrelated project tasks, the material names, the quantity, the planning time, the material attributes, the upper and lower channel associations and the like are parameters of the project tasks, the project tasks can be flexibly changed without changing the project task numbers, and the method has stronger flexibility compared with the traditional production worksheet of material dimension. When the project requirements, the complete set and the task progress analysis deviate, the task arrangement of the whole project can be refreshed by adjusting the project priority, the requirement time, the project BOM and the like.

Step 6, the production work order is analyzed in a complete set (requirement balance of general production work order)

And analyzing the complete set condition of the materials before the production work order of the MRP module is on line in the production arrangement so as to facilitate the production to be executed according to a plan and avoid the on-line stop and the waiting of the materials.

Because the project requirements are virtually transferred to a 'project resource virtual library' (the warehouse is set to be not involved in MRP calculation), the complete set of production work order analysis and the complete set of project requirement analysis of the MRP module are not interfered with each other, but universal part resources can be optimized and allocated mutually.

Step 7, production scheduling and execution (production work order and production task combined scheduling)

After the process is completed and the progress is analyzed, the production work orders of the MRP module and the project production tasks of the PRP module are combined and optimized according to the productivity of a workshop.

A PRP module:

the project self-manufactures a production task to start and receive materials, the production task is handed to a next task according to the task specification after completion, the task state is updated, finished warehousing and next material receiving are not needed, and the PRP module is not provided with a warehouse. If all the processes of the process route decomposition exist in the project production task, the processes are the process activities in the task, and similarly, all the processes are started and material is received, and the finished product is handed to the next process or the next task according to the task specification.

The method comprises the steps of project special-purpose piece purchasing task, triggering special-purpose piece material purchasing orders (different bill types) after starting operation, receiving the purchasing orders in a fee mode (without material warehousing and ex-warehousing) after the special-purpose pieces arrive, triggering completion of corresponding purchasing tasks after the purchasing orders are received and confirmed, and absorbing the purchasing cost of special-purpose piece materials.

The project special part outsourcing task comprises a task level outsourcing and a task process activity level outsourcing, except for conventional start and warehouse material fetching, an outsourcing processing cost purchase order is triggered after the start, the outsourcing processing cost purchase order is received in a cost mode after the outsourcing part arrives, the outsourcing processing cost purchase order is not subjected to material warehouse entry and exit, and after the receiving of the outsourcing processing cost purchase order is confirmed, completion of the corresponding outsourcing task is triggered, and the cost of the outsourcing material and the outsourcing processing cost is absorbed.

And the MRP module is used for:

and (5) the production work order and the purchase order are delivered and stored in a warehouse according to the material form convention.

Step 8, logistics management (material of project production task)

A PRP module:

and (4) after the project production task is started, feeding the materials to a project task processing group according to a project task (activity) standard material receiving list triggered by the step 3, the project requirement complete set and progress analysis.

Excess material getting processing of tasks:

and (3) filling an excess material receiving list of the project task when the standard material receiving quantity is insufficient and excess material receiving is needed due to the reasons of process loss and the like, simultaneously triggering and increasing a new project requirement of the current level, triggering a new excess material receiving task of the same level if the requirement is a special part requirement, transmitting the new excess material receiving task of the same level to the step (3) and calculating the requirement gap of general parts of each project if the requirement is a general part requirement, and receiving materials from a project resource virtual library by using an MRP module inventory.

In order to distinguish cost responsibilities, the excess material receiving task generated by the excess material receiving sheet of the special part is provided with two fields: the system comprises a cost organization and an execution organization, wherein the cost organization is an organization for opening an excess material obtaining list, the execution organization is only responsible for completing tasks, and the generated task cost is collected into the cost organization.

Borrowing processing between items:

for general parts borrowing, the priority of a borrowing item is increased, a rule system is set to recalculate and refresh material resource occupation allocation according to the updated sales contract priority, and the resource occupation of partial tasks can be locked without participating in material reallocation;

for borrowing of special purchasing and outsourcing parts, each purchasing task and purchasing order of a borrowing party and a borrowed party are set as a community through borrowing change lists, the priority of a borrowing project is increased by default, the purchasing order of received goods is re-matched with the direction of each project task according to the sales contract priority, the collective verification and sales comparison sequence relation of each purchasing order and purchasing task in the community is changed, the project requirement matching and progress analysis table of the purchasing tasks is updated, the purchasing task cost of the projects is synchronously updated, and real objects are used according to the re-distribution quantity.

For item intermediate semi-finished product level special manufacturing piece borrowing (as shown in fig. 5), (1) a project task corresponding to a borrowed semi-finished product is disconnected from an original project, the project task is transferred together with related previous multi-tasks to generate a new project, a cost project code is updated, a project task low-level code is updated downwards in 0 order, the project task low-level code is put into a general-purpose piece library to serve as a public resource, and meanwhile, the project cost is calculated and transferred to the semi-finished product material cost. (2) The method comprises the following steps that a borrower modifies corresponding sub-pieces of borrowed semi-finished products into general pieces in a project BOM, and the corresponding semi-finished sub-pieces in the borrowed project BOM are divided into two sub-pieces: one sub-piece material attribute is a special piece, the loaned quantity is used as a required quantity, one sub-piece material attribute is a general piece, and the residual quantity after loaning is used as a required quantity (the quantity is not required to be generated when the quantity is 0). (3) The method is characterized in that the order priority of a borrower is higher than that of a borrowed party by default, the demands of the borrowed party and the borrower party on semi-finished products are calculated by PRP again, sub-pieces are modified into the demands of common pieces, semi-finished product material resources are distributed to the borrower and the borrowed party according to the order priority by the step 5, project demand matching and task progress analysis, the sub-pieces are the demands of the borrowed party of special pieces, and project production tasks and lower-level decomposition demands of borrowed quantities are regenerated.

The MRP module:

after the production work order is started, materials are picked up from a warehouse in a material mode according to the conventional legal material picking up and excess material picking up processes.

Step 9, product cost management (calculation of general parts product cost)

And processing general parts of the MRP module according to a conventional cost accounting method, and calculating the actual cost of work order materials by adopting a step-by-step method or distributing the cost difference by adopting standard cost circulation.

Step 10, project cost management (calculation of project task cost at each level)

Including project budget costs and project actual costs. The premise is that the product cost is calculated, and the universal part material receiving cost of the project task can be measured.

The item number has two fields: the project number and the cost project number are subject to the cost project number in the project cost calculation, so that the flexibility of the project cost calculation in the project change process is improved. The two fields are the same initially, but when borrowing between projects is carried out to cut off tasks and generate a new project, the cost project number field is updated to be a new project number, the project number field is kept unchanged, and the project cost is prevented from being still collected to the original project.

The project cost calculation logic of the PRP module is shown in fig. 6:

the overall project is that each level of task absorbs task material, labor and cost, after completion, the task/process cost is independently and parallelly thrown according to a low-order code sequence in sequence when the cost is up, and the cost of each task is directly added to be equal to the cost of the whole project.

Firstly, a final-stage project task absorbs materials, labor and cost of the task, the cost of the task is calculated along with the completion of the task, the cost is all thrown to the project in parallel, and a processed semi-finished product is transferred to the next process;

the next task absorbs newly-added materials (only the cost of material picking of the task from a warehouse is calculated, the cost of the semi-finished product transferred by the previous task is thrown, and the repeated calculation is not carried out), labor and expenses, the cost of the task is calculated along with the completion of the next task, the cost is thrown to a project in parallel, and the project is turned backwards;

and (4) sequentially throwing the cost absorbed by the tasks to the project by the follow-up tasks according to the sequence of the low-order codes until the task absorption and throwing of the 0 order are completed.

And after all tasks are finished, the whole project of the sales contract line is finished and closed, and the project cost is generated.

If the project task period is long and the project task is finished in a monthly span, the material, labor and cost of each month are respectively absorbed according to the month.

The calculation logics of the project budget cost and the project actual cost are the same, the cost structure is the same, project task-level cost comparison can be carried out, and cost management is refined.

Step 11, converting project cost into product cost

Because a group type company may have a part of subsidiaries which do not adopt a project manufacturing mode, in order to unify the settlement apertures of products sold and delivered by the group, products of the project can be put in storage before the sale contract project is finished and closed or delivered, the project number is used as a product batch number for distinguishing and tracking, and meanwhile, the project cost is converted into the product cost.

If no demand exists, the 'shipping' of the sales contract item can be used as a 0-order task to decompose the demand of the delivery product, if the demand is a general-purpose item demand, the warehouse delivery is absorbed in the cost of the delivery task, if the demand is a special-purpose item demand, the item task is regenerated, and the layer-by-layer decomposition is carried out.

As shown in fig. 7, assuming that the process of manufacturing the product mixture of the project service of the present invention by mixing the PRP and the MRP for the project requirement is embodied as an oil-electricity mixed extended range new energy vehicle, the whole process is respectively pulled and pushed by two engines of the Project Requirement Planning (PRP) and the Material Requirement Planning (MRP), and the pull and push are combined and combined with the stock to balance the project requirement and the resource supply. The PRP and the MRP respectively correspond to a generated project task, a purchase order and a production work order, are front and back driven wheels, and are used for promoting project operation and absorbing cost. The project work decomposition structure is a road sign of a road and records the operation process of a project. Production planning and scheduling (APS) is a navigator to allocate resources and optimize the best route. The project low-level code controls the cost budget and actual cost accounting of the project.
